We have been drinking beer on the beach all our lives to cool off. Science warns of great danger to our body

by

On any summer afternoon, the beaches and terraces are filled with people seeking refuge from the high temperatures, and the instinct of the vast majority is to order a cold beer. This classic drink in Spain gives a false sensation of immediate coolness and temporary relief, but here the question we must ask ourselves is: is it really useful to drink it to alleviate the sensation of heat? A myth. Given this classic scene, science suggests that it is a bad idea to have a beer to quench thirst, since alcohol causes exactly the opposite by triggering a response that dehydrates us. And this is explained by a fundamental hormone called vasopressin or antidiuretic hormone. As its name indicates, its function is to retain water in the kidneys when the body needs it because it is dehydrated, and alcohol suppresses it almost immediately. And it is something proven, since studies show that ethanol blocks the release of vasopressinpointing out that after ingesting alcohol, an acute drop in this hormone is observed in the bloodstream. This causes the kidneys to stop reabsorbing fluids and begin to expel water at a rapid rate to promote the production of urine and, therefore, the loss of fluids. an experiment key here demonstrated that the subjects studied lost up to 0.9 kg of water weight in just two hours. That is, for every beer you drink to “hydrate” your body expels more liquid than it consumes. And this is a context of heat and high sweating; It is a one-way ticket to a state of dehydration if you do not also drink water. The broken thermostat. The second big problem with drinking alcohol in the sun is thermal. Alcohol is a powerful vasodilator and this means that it widens the blood vessels, bringing more blood to the surface of the skin, which produces that typical facial flushing and sudden feeling of heat when we drink. And although at first the breeze on the skin may make us feel cooler, we are actually compromising our ability to regulate internal temperature. A model published in International Journal of Legal Medicine demonstrated that drinking alcohol before facing a high temperature environment drastically worsens the body’s response. Alcohol literally “hacks” the brain nuclei responsible for thermoregulation, activating abnormal responses of the body to heat. Water is the best. Drinking a cold beer has logically become socially rooted in our society, but when you are thirsty and have been sweating for a long time, it is best to hydrate with water first. And this also confirms that there is no alcohol that is “safe” from a medical point of view. Non-alcoholic beer can be an option since, since it is composed mainly of water and lacks alcohol, it does not have an effect on our antidiuretic hormone.

“The problem is not drinking coffee, it is needing five cups to be functional”

by

It is the first action of the morning for millions of people, the starter of offices, the companion of night shifts and the fuel of exam times. For a long time, coffee has been at the center of the nutritional debate, often demonized for its stimulating effects, but now this is something that is slowly changing. The problem. Just like pointed out Recently, the psychologist María Ros, the real elephant in the room is not the substance itself, since the problem it’s not drinking coffee“it takes five cups to be functional”. In this way, when we cross the line between enjoyment and absolute dependence on keeping our eyes open, the focus must move away from the coffee maker and onto our lifestyle. The consumption barrier. To understand when coffee becomes a problem, you must first establish what is safe consumption. The main international health agencies are quite unanimous on the matter, since, for example, the EFSA established at the time a clear opinion that today serves as a standard: for healthy adults (not pregnant), consumption of up to 400 milligrams of caffeine per day does not pose safety problems for our health. To put it in perspective, an espresso is around 60-80 mg, and a cup of filter coffee can be closer to 100-150 mg. That is, we are talking about a margin of about three or four cups a day. In the case of the US regulator, matches with these figures, and points out that unwanted effects begin to emerge the moment this threshold is exceeded. The positive side. Beyond not being dangerous, the latest evidence point because regular consumption of 3 to 4 cups a day could be more beneficial than harmful. This fits into different articles that associate moderate consumption with lower mortality and a reduced risk of developing various pathologies. Even at a cardiovascular levelan area where coffee has always generated suspicion, current medical literature emphasizes that in regular consumers the effects on blood pressure are transitory and reversible. The danger of coffee. We speak at these levels when it stops being something pleasurable and becomes an urgent need to combat mental exhaustion. This way, if a person needs to binge cup after cup simply to avoid experiencing crippling drowsiness or to be able to stay focused on their work, coffee is acting as a painkiller for an underlying problem that needs to be addressed. We must remember that caffeine works by blocking adenosine receptors in the brain, the neurotransmitter that makes us feel tired. It doesn’t eliminate tiredness, it simply puts a “bandage” on the brain’s sensors, so using large amounts of caffeine to compensate for chronically insufficient rest creates a perfect storm. The experts. Institutions like the Mayo Clinic warn of the cascading effects of this excess by pointing out that tolerance is capable of developing, causing more and more caffeine to be needed for the desired effect. The problem is that overconsumption quickly leads to anxiety, nervousness, headaches, palpitations, tachycardia and digestive problems such as worsening gastroesophageal reflux. Furthermore, a vicious circle is created, since if you drink a lot of coffee to perform because you have slept poorly, that excess of circulating caffeine will prolong sleep disturbances the next night, feeding back stress and insomnia.

We have been told that drinking water on an empty stomach helps you lose weight. Scientific evidence says otherwise

by

The Internet and social networks are full of supposedly easy tricks that promise almost miraculous results with a minimum effort for our body. One of these tricks is a habit that many people do as if it were a ritual: drinking a large glass of water, “yes or yes”, as soon as we get out of bed in the morning. This simple gesture promises to ‘wake up’ the intestines, activate the metabolism and promote weight loss. It’s a myth. What we hear on social networks is not always true, since we must face a large number of myths that have no scientific support behind them. And right now the best scientific evidence does not support this idea, Although it is true that drinking water increases our energy production. Thermogenesis. To understand where this widespread myth comes from, we must analyze the term “water-induced thermogenesis”, that is, the ability of our body to begin producing energy after drinking a glass of water. Here is a classic study In the medical literature it was observed that the consumption of 500 ml of water managed to increase the metabolic rate by around 30% during a period of 30 to 40 minutes. But although this percentage may seem incredible, the reality is that the acceleration of the metabolism translated into a total expenditure of 24 kilocalories. That is to say, its effect was so small that short-term weight loss was hardly going to be noticed due to this. It has been verified. Subsequent research in the fields of endocrinology and nutrition has attempted to replicate these data in different contexts. We have one of the examples in a clinical trial that evaluated the physiological effects in overweight or obese people, where an increase in energy expenditure of 24% was found for 60 minutes after ingesting 500 ml of water. But again it was seen that this slight temporary metabolic rebound does not imply a fat loss that is relevant in itself. On the scale. If now, instead of staying in the laboratory, we go to the real effect that this habit has on patients, we find that the narrative of water on an empty stomach as a slimming remedy loses much of its support, since the scientific evidence on weight loss attributable to water consumption is, in general terms, limited and of low to moderate quality. And the studies that have been done, despite pointing to weight loss, have a follow-up that is too short and a methodology that prevents giving a firm conclusion about applying this recommendation. The power of water. That dismantling the myth of a glass of water on an empty stomach is anticlimactic does not mean that hydration has no value in a weight control strategy. And the evidence suggests that drinking water helps to lose weight indirectly, since the mere fact of modifying the diet to go from a high consumption of sugary soft drinks or industrial juices to drinking water eliminates hundreds of calories a day with little effort. In addition, various trials suggest that drinking water before meals makes us feel full much sooner, which will reduce the amount of calories that we end up eating and, therefore, advancing a little further in the diet.

Drinking tap water in Asia is almost crazy except in a country where it is a source of pride: Singapore

by

Whether for work or vacation, I have traveled to Asia on several occasions and one recommendation has always followed me: “always drink bottled water”, even for tasks like brushing your teeth, it is better not to risk it and rinse your mouth with water that you know is safe. The recommendation spreads to most of East and South Asia, with destinations such as Thailand, Vietnam, China and India. However, a little over a week ago I visited Singapore and there was something that fascinated me: it’s not just forgetting to always carry a bottle of water, it’s that there wasn’t even one in the hotel room. Instead, a message recommended drinking tap water because it was of exceptional quality. That a country has quality water is not something miraculous, but Singapore is an anomaly in itself: it rains a lot, but it barely has land, so it lacks large aquifers or large rivers. In fact, for decades it depended on water imported from Malaysia (still doing it). However, they have managed to build one of the most advanced and reliable water treatment systems in the world thanks to the engineering and public policy behind it. The four national taps. In 2001 the public agency Public Utilities Board (PUB) assumed full control of the water cycle with a unified vision: from rainwater to the water that falls down the drain, achieving a snapshot of the whole, available and necessary resources. Singapore’s maxim with water is divide and conquer. Thus, it has four different water sources, the Four National Taps managed by the PUB: water from local basins, water imported from Malaysia, reused water and desalinated water. Taking into account that Singapore has had its ups and downs with Malaysia, the other three taps have been gaining importance. Marina Barrage, Singapore’s 15th reservoir to store water. Bob Tan Why is it important. In Southeast Asia, water pollution from industrial waste, agrochemicals and a heterogeneous and deficient sewage network means that the norm is to use bottled water. We have already seen that Singapore lacks the land to achieve water self-sufficiency and depending on a third party for something as basic and essential as water is a dangerous alternative. In this scenario, NEWater stands as the most strategic tap: self-generated water without depending on rain, the terrain or the neighbors. Although with quite a bit of small print. The local watershed. Through a network of drains, canals and rivers, rainwater is collected and channeled through its 7,000 kilometers of pipes to its 17 reservoirs before treating it for consumption. This collection takes place in two thirds of Singapore’s territory. From here, the water follows a conventional purification system. It is the least innovative route, but it is solid, functional and growing: the construction of the eighteenth reservoir is already planned on the land that Singapore is reclaiming from the sea, Long Island. Water imported from Malaysia. This is the most vulnerable tap and therefore the most susceptible to being eliminated (for now, minimizing as much as the rest of the taps can). He first agreement between Singapore and Malaysia dates back to 1927 and laid the foundation for water supply and land leasing on Gunung Pulai, but is no longer in force. This was followed by three other agreements signed in 1961, 1962 and 1990. Initially this source provided half of Singapore’s demand, but as explains the National Library and National Archives of Singaporefollowing the expiration of the 1961 agreement in 2011, the government aims to be self-sufficient by 2061, when the 1962 and 1990 agreements end. Sewage. Is called NEWateris capable of covering 40% of the total demand of the country and from wastewater it is capable of achieving drinking water of superior quality to standards of the WHO. They tried it before, in 1974, but the project failed due to costs and technical problems. The current sewer system cost 10 billion dollars and is designed to last 100 years. It all starts underground: the sanitation system DTSS It collects all the urban wastewater through a 206-kilometer network and takes it by gravity (without the need for pumping) to the four recovery plants located in Ulu Padan, Kranki and Changi (there are two there). There they use membrane bioreactor, reverse osmosis and ultraviolet disinfection technologies. They currently have a global recovery rate of 90% and a capacity of 227,300 cubic meters per day. NEWater operation diagram. Data. NEWater with Gemini translation Seawater desalination. Singapore It has five desalination plants and all of them use reverse osmosis as the main treatment, although with different pretreatment combinations. Desalination is a well-known technique in water engineering, but little applied for one reason: costs. So to optimize the energy process, among the PUB’s main R&D objectives is to reduce energy consumption to less than 2 kWh per cubic meter. The first was SingSpring and is capable to produce 136,380 cubic meters of water per day, covering around 7% of the country’s water needs. The Tuas plant won the “Oscar” of salinization plants in 2019 thanks to an advanced pretreatment system that combines dissolved air flotation and ultrafiltration to mitigate membrane fouling. Keppel Marina East has an adapted dual system that works for both seawater and freshwater. Yes, but. From a technical point of view, Singapore’s water infrastructure is brilliant, but it is not without its problems. The first is energy: desalination consume 3.5 kWh per thousand liters of treated water, much more than 0.7 kWh NEWater Faucet. Desalination has a high environmental and economic cost and is highly dependent on electricity. Spoiler: about 95% of Singapore’s electricity is generated from imported natural gas. On the other hand, drinking water that comes from the sewer, despite its quality, generates a certain social rejection, which is why the majority is destined for industry, where such pure water is ideal for the manufacture of semiconductors. On the other hand, faced with a growing demand for water, the challenge for the future is scalability to maintain its reliability based … Read more

drinking alcohol is for old people

by

We knew that it takes years expanding strongly throughout Spain and which attracts more and more people, but the great proof that the ‘late’ has become a massive phenomenon just arrived now. And in the form of report. The trend has grown so much that the nightlife employers’ association has dedicated a study to it that analyzes its impact and clientele in detail. Among all his conclusions there is one eloquent one: he already moves 26.5% of the billing of leisure venues. And there are no signs that that will change. From the bars to the office. There are several signs that reveal to us that a trend has become a business with a future: people begin to talk about it on the street, it grabs headlines, it generates noise on the networks… All this ‘lateness’ been doing it for years. Now it adds a new clue that confirms that it has stopped being a passing fad and has become a real gold mine for the hospitality industry. The National Federation of Leisure and Entertainment Entrepreneurs (‘Spain at Night’) has just dedicated its first sector studya comprehensive report that answers some key questions about a trend that basically involves advancing a leisure offer that until recently was limited to nighttime hours: How and when did it emerge? What audience does it move? And how much money does it generate? The key data: 58.8%. There is who places the origins of ‘tardeo’ in Albacete at the beginning of the 2000s, from where it first made the leap to the Levantine coast and later (thanks to the changes in habits brought about by the pandemic) to the rest of the country. Whether or not this is the case, the undeniable thing is that the ‘lateness’ has had a deep impact on the sector. The study concludes that they have opted for it close to 58.8% of leisure and hospitality venues, which explains why it accounts for 26.5% of their turnover. They are not the only percentages that give an idea of ​​the extent to which hoteliers have been jumping on the bandwagon of evening leisure. The same report shows that 62.2% of the clubs hold afternoon sessions every weekend. If we talk about cocktail bars, they are 41.4%; and 24% among restaurants. Who late? That’s probably the most important question the study answers. The public that usually moves the ‘evening’ in Spain is on average 39.4 years old, significantly above the average nightlife clientele, which is around 29. It may seem like a minor or even obvious fact, but it is essential to understand other peculiarities of the trend. The increase in age is also accompanied by greater spending: if the average ticket for night owls is 20 euros, in the case of late-night regulars the average rises to 25. This is not bad at all if we take into account that for years bars have been dealing with another phenomenon: a generation Z that seems less interested in alcohol than his predecessors and is changing the way of drinking. New format, new offer? That profile millennial or generation the leisure offer of the afternoon sessions. Customers order mixed drinks with vodka, gin, rum or whiskey, although they also drink beer, soft drinks and glasses of wine. As for music, it is not strange that people look for songs that were played during their youth. “Until recently the favorite music was the so-called ‘remember’. Now we are in ‘afternoon 2.0’. We started to see afternoon ‘indie’ sessions for people who went out at night 10 years ago,” explains to The Newspaper Vicente Pizcueta, from Spain by Night. Partying yes, but conciliating. The success of ‘afternoon’ cannot be understood without taking into account the pandemic and how it altered our leisure habits, giving more relevance to the evening offering. However, there is another factor that explains why we are increasingly opting to go out in the afternoons: Spain gets older little by little. In 1975 the average age was 33 years, today it is over 44.5. This makes it clear that the weight of a more adult client profile who still wants to party, but who at the same time has other obligations, such as dependent children, has increased. The vast majority of the ‘afternoon’ offer continues to be concentrated on Saturdays (84.9%) and 63.4% of those surveyed recognize that what leads them to go out is to enjoy with their friends, but there is another data that is equally revealing: 38.9% look for options that are compatible with their family life. “It is true that the issue of conciliation is fundamental,” confirm Pizcueta. “You go out in the afternoon, leave the children with the grandparents, pick them up at dinner time, go to bed early and the next day you can get up early to go to the countryside.” Do we know anything else? Yeah. The reportin which Coca-Cola has also participated, leaves out some interesting ideas that help to better understand ‘lateness’. For example, although DJ sessions are the most common, there are also many celebrations that combine music with gastronomy, offer live music or even opt for themed and private parties. That the format has convinced so many businesses is not surprising either. Especially if we talk about bars and clubs. Although the public that attends afternoon and night parties is so different that sometimes businesses have to clearly divide both sessions, the ‘afternoon’ allows them to extend their hours of activity. They open earlier, bill earlier, earn more. According to the hoteliers’ study, on average the ‘afternoon’ sessions start around 5:30 p.m. Images | Marcel Strauss (Unsplash) and Artem Polezhaev (Unsplash) In Xataka | Madrid has been filled with “dopamine parties”: alcohol is gone, salads and ice baths are here

Young people are stopping drinking beer like crazy. That’s why Mahou wants to sell you water as cosmetics

by

On May 28, social networks in Spain woke up flooded with pink, lychee and promises of beauty. That day YUZZ saw the lightthe new business adventure of the influencer María Pombo in alliance with the brewing giant Mahou San Miguel. Under the motto Here You Glowis presented not as a simple drink, but as a revolutionary concept of fun skincare: a soft drink that “takes care of you on the inside so that you shine on the outside”, formulated with hyaluronic acid and vitamin C. The deployment was massive: the strategy started with mystery videos, a WhatsApp channel that was fuming with thousands of followers looking for clues and culminated in an experience pop-up in the heart of Madrid. However, beyond the indisputable success of the call, the launch uncovers a striking contradiction: that of an industry traditionally linked to nightlife and beer trying to bottle the idyllic universe of health, cosmetics and well-being. Why does a brewery sell beauty? Beer is beer you might be thinking. However, the alcoholic beverages sector is going through a moment of profound transformation in the face of the decline in consumption among new generations. This is where they make the leap towards functional soft drinks, since it responds to an unstoppable global trend. In fact, the wellness market It already moves 480,000 million dollars in the United States, with annual growth of up to 10%. Europe follows in the same wake, and Mahou is looking for its piece of the pie. But to connect with Generation Z and millennials It is not enough to launch a product; a narrative is needed. This is where María Pombo comes in. The industry is witnessing an evolution of influencer marketing, it is no longer about paying a well-known face to hold a can, but rather a “shared business model” based on co-creation. Pombo has been involved from day one, sharing the development process organically with her more than four million followers. This drastically reduces the consumer’s natural resistance to conventional advertising. The label under the magnifying glass. While marketing works perfectly, the scientific community has raised eyebrows when analyzing the list of ingredients. Can you really drink cosmetics? According to Dr. Emiliano Grillo, specialist in Dermatology, is blunt in the magazine Cuore: “There is no way for you to eat the skincare“. The expert warns that, for oral hyaluronic acid to have a real impact, it would require much higher doses than those anticipated in this type of recreational formats. But the biggest problem with YUZZ is not what it promises, but what it hides: sugar. Although the brand prides itself on being a low-calorie drink without sweeteners, nutritionist Paola Sánchez explains in the same medium that each can contains about 10 grams of sugar, the equivalent of two cubes, from the concentrated apple juice that serves as a base. The pharmacist Mencía Hermosa goes one step further and points out the paradox of the product: the consumption of sugars is directly involved in the glycation process, a mechanism that damages collagen and “contributes to skin aging.” That is, the soft drink could be torpedoing the effect it promises to generate. For her part, the pharmacist and disseminator Lena de Pons dissects the formulation in Infobaedenouncing that “the narrative sells more than the evidence.” De Pons clarifies that YUZZ is governed by food regulations, not cosmetics. Legally, they can only claim that it helps collagen because it covers 15% of the Nutritional Reference Value (NRV) of vitamin C, a tiny amount. “A fruit salad has more antioxidants,” says the expert ironically, also regretting that the word “science” is used in the campaign without providing independent studies that support the bioavailability of its formula in the body. The undeniable triumph of narrative. At the end of the day, the reality of YUZZ depends on the lens through which you look. If we evaluate it under the rigor of dermatology, trying to replace a cream with a soft drink is nonsense. As a timely and recreational alternative to a mixed drink with alcohol or a traditional soft drink loaded with artificial additives, it is an option that the experts themselves consider acceptable. But in the corporate field, the move is masterful. How to conclude Article 14in a saturated market where attention is the rarest commodity, getting an entire country to debate about your brand is the greatest success. Mahou and María Pombo have made the initial impact. Now they face the real challenge: to demonstrate that this cross between a brewery and skincare It has enough commercial history to survive on the shelves once the noise of social networks has died down.

As towns dry out and the desert advances, women in Morocco climb the mountains to capture the fog and turn it into drinking water

by

A chance experiment took place in the 1980s. Some researchers working in the Atacama Desert accidentally left a simple metal mesh exposed to wind at night. The next morning they discovered that it was covered in water droplets in one of the driest places on the planet. That seemingly trivial scene ended up inspiring an idea that decades later would change the lives of entire towns. Capture the fog before it disappears. As the desert slowly advances over southwestern Morocco and traditional wells begin to dry up, several villages in the Aït Baâmrane region have found a solution which seems closer to a science fiction image than to conventional hydraulic infrastructure: capture the fog from the mountains and convert it into drinking water. For generations, the women of these communities spent up to four hours a day walking to remote wells and returning carrying barrels weighing almost 25 kilos on their heads. That routine organized the entire life of the villages, kept many girls out of school and reflected the extent to which the lack of water conditioned any daily activity on the edge of the Sahara. Giant nets convert air into water. The change began when huge polymer networks They appeared on the slopes of Mount Boutmezguida, at more than 1,200 meters above sea level. The idea is surprisingly simple: take advantage of the moisture from the Atlantic fog that regularly passes through the Anti-Atlas mountain range. The tiny droplets become trapped in the mesh, condense and end up descending towards deposits connected to kilometers of pipelines by gravity. Without complex pumps or large industrial infrastructure, the system manages to carry water directly to homes using only wind, altitude and ambient humidity. Thanks to the advances in materials engineeringthese modern networks are much more efficient than the experiments carried out decades ago in countries like Chile, Yemen or Eritrea. And the fog reached the tap. When the system went live, neighbors gathered to see something they had never seen before: water coming directly from a faucet inside a home. That “fog water”as they began to call it, quickly transformed the daily life of the villages. Women stopped spending part-time carrying water and many girls were able to attend school regularly again. The project, promoted by the NGO Dar Si Hmadnot only modified water management, but also the social balance of communities where transporting water had been an exclusively female responsibility for centuries. The cultural challenge of drinking water that did not touch the ground. The technology worked from the beginning, but convincing everyone was much more difficult. Some inhabitants they distrusted of a water that had never passed through the earth and that, as they believed, lacked minerals and “life”. The fog represented something ambiguous, almost unreal, too far from traditional sources. Over time, the rejection disappeared as the families verified that the water was safe and constant. The transition also forced us to work unexpected social issues: Some women felt that they were losing part of their central role in the home by no longer being in charge of fetching water. That is why the project ended up incorporating literacy, technical training and community management along with hydraulic infrastructure. Finding water is impossible. The UN has recognized this May 2026 that the Moroccan system is one of the more interesting examples of climate adaptation against desertification. The project shows that some extremely dry regions can still take advantage of invisible resources which until now were hardly used. However, it also makes clear that does not exist a universal solution: capturing fog only works where mountains, ocean humidity and very specific atmospheric conditions coincide. Still, the image is powerful for a planet increasingly affected by water scarcity: as wells empty and temperatures rise, there are entire communities in Morocco that have literally begun to harvest clouds to survive.

why drinking a Diet Coke in the middle of 2026 is an impossible mission

by

Any consumer who has recently walked through the soft drinks aisle in a supermarket will have come across a particular scenario: the word “light” (or “diet”, depending on the country) is conspicuous by its absence. Instead, a tide of “zero label” cans and bottles dominate the shelves. Everything indicates that the iconic Diet Coke is in the doldrums. However, it is enough to look at social networks to discover a little resistance. Among young people of Generation Z, this drink has not only not disappeared, but has become a true object of desire and a lifeline against work stress. And to make matters worse, in the middle of 2026, opening one of these cans has become almost a miracle due to a geopolitical and logistical crisis that is suffocating the world. What is really happening with the Diet Coke? The rise of “Zero” At the beginning of this decade, the industry left the word “diet” for dead. “No Gen Z person wants to be on a diet these days,” sentenced in 2021 Greg LyonsCEO of PepsiCo, illustrating what seemed like a definitive change in mentality throughout the industry. Corporations assumed that young people associated the term with strict regimes or deprivation, while the designation “zero” offered a much cleaner profile. As a result, The Coca-Cola Company has put all its financial muscle behind its Zero variant. The financial data they confirm it: during the third quarter of 2025, Coca-Cola Zero Sugar experienced an impressive 14% growth. In contrast, the Diet Coke (either Diet Coke) barely expanded 2%, driven almost exclusively by demand in North America. On a technical level, the difference between the two is not a myth. As detailed in the German media RNDthe Diet Coke Original has a slightly different flavor than classic due to its specific blend of artificial sweeteners (aspartame and acesulfame K) and flavorings. The Coca-Cola Zeroon the contrary, was formulated years later with the explicit objective of imitating the brand’s original flavor as closely as possible, attracting an audience that was fleeing the stigma of “regime” products. Welcome to the “Fridge Cigarette” But Internet culture has its own rules, and corporations don’t always dictate trends. Far from dying like a drink for the generation boomerthe Diet Coke experienced a brutal organic resurgence from 2023. It all started with viral trends that invited you to “marinate” the can in the refrigerator for days to enhance its bubbles, and reached its peak when superstars like Dua Lipa showed on TikTok how they mixed the drink with pickle juice and jalapenos. This fervor led to a new concept that has taken the internet by storm: the fridge cigarette (or “refrigerator cigarette”). Young people have adopted the act of opening a can of Diet Coke cold like the modern equivalent of going out for a cigarette. For Generation Z, the metallic sound when opening the ring emulates the spark of a lighter. It’s not about nicotine, but about the ritual: a perfect excuse to get up from your desk, get away from the screen and claim a little break in the midst of modern hyperproductivity. It is an act of self-care disguised as rebellion. The company, of course, was quick to notice. Sue Lynne Cha, vice president of marketing at Coca-Cola, recognized this rebirth among young people, leading the brand to invest heavily in this renewed popularity. They launched campaigns very focused on Generation Z, such as “Love language” and “Know The Signs”, the latter narrated by comedian Kristen Wiig, encouraging workers to take a #DietCokeBreak. To sustain this momentum, the company injected an additional $18 million into advertising in 2024 alone. The “Black Swan” of 2026 Just when the Diet Coke crowned as the status symbol of work breaks, geopolitical reality dealt it a lethal blow. Right now, the world is facing an unprecedented raw materials crisis. The Third Gulf War has blocked the main sea routes of the Middle East, a region that concentrates almost 9% of the global aluminum supply. This bottleneck has generated a deficit of two million tons, skyrocketing prices and forcing European smelters to declare “force majeure” situations. How does this affect the “refrigerator cigarette”? Directly on the waterline. No aluminum, no cans. The shortage is so severe that in regions like India—where Diet Coke sold exclusively in this format—the drink has almost completely disappeared. According to FortuneIndian entrepreneurs have capitalized on this drought by organizing clandestine themed parties where admission is charged and coveted cans are raffled off, turning the Diet Coke in a true luxury item. This desperation is not trivial in a country where, according to the Indian Council of Medical Research, almost 10% of the adult population is diabetic and depends on sugar-free options to indulge. An effervescent mixture Added to this cocktail of logistical scarcity and network fanaticism is the eternal debate about health. Historically, cola drinks have been in the medical spotlight. Specialized portals such as WebMD and Medical News Today They constantly warn about the risks associated with these soft drinks, linking them to insulin resistance, increased visceral fat and even arguing that the dopamine spike they generate in the brain is comparable to that of highly addictive substances. With the version lightthe focus is on its sweeteners. a study published in Cell Metabolism suggests that aspartame could be harmful to cardiovascular health in mice, although the European Food Safety Authority (EFSA) and other experts have remained skeptical of this methodology, reaffirming that normal doses are safe. And what do new consumers say about this intersection of medical accusations? Which doesn’t matter exactly the same to them. Unlike the millennials Obsessed with wellness, Generation Z embraces this drink with an almost nihilistic attitude, driven in part by a 2000s nostalgia that has resurrected old aesthetic standards. As Andrea Hernandez, founder of the newsletter, explained Snaxshot, to The New York Timesthe mentality is: “Oh, aspartame is terrible for you… I absolutely don’t care.” It is an affordable vice, a small transgression in a world full … Read more

has reclaimed 25% of land from the sea and converts wastewater into drinking water

by

There is a country in the world that, when it runs out of space, manufactures more. And when it doesn’t have water, it recycles it infinitely. It’s not science fiction: it’s Singapore, a city-state that surpasses the six million inhabitants concentrated on an island that was barely 580 square kilometers and that today it occupies 736 square kilometers. A growth of almost 25% in just over half a century. It is not ambition, but necessity: it does not have enough land or its own rivers or aquifers, so it has had to cook everything for itself. Since its independence from the United Kingdom, it has not only increased its surface area: it has also built one of the most sophisticated water management systems on the planet, capable of converting wastewater into drinking water. of superior quality to standards of the World Health Organization. Singapore’s territorial resilience. Singapore has understood that its land and water (scarcity) problems are not independent, so it is solving them jointly and in a long-term plan (its sewage system is literally designed to last 100 years). It is the urban resilience applied to territorial development in its maximum expression, that is, the capacity of a territory to face climate, demographic and economic change through its infrastructure. A concept promoted by organizations such as the United Nations Office for Disaster Risk Reduction of which Singapore is today the most advanced student. A living laboratory in real time. If those southern geometric shapes don’t seem natural, it’s because they aren’t. Google Earth Context. The quick response to why is Singapore doing all this? It is because it lacks land and water, but reality is based on three essential axes that invite urgency: Geography. Singapore is a small island (more than New York) with a brutal population density, it does not have mountains that function as a natural reservoir or large rivers or aquifers. The rain is abundantbut collecting it in such a small field is a challenge. Strategic dependence. Historically, it has imported water from Malaysia through different agreements (the last one expires in 2061) but that represents a strategic vulnerability of the first order. Also they have imported sand from neighboring countries such as Indonesia, Vietnam and Cambodia. Climate change. Singapore is especially vulnerable to the threat of sea level rise as 30% of the territory is less than 5 meters above mean sea level. How to gain land. We enter first-class public works engineering. The traditional method consists of dredging sand from the seabed, transporting it to where it is required and filling the hole. The problem is that Singapore has run out of sand to dredge and no countries to sell it to it. As own governmentcountries such as Malaysia, Indonesia and Malaysia have banned sand exports to Singapore over the years citing environmental reasons. The second method is the dutch poldera construction that consists of setting up a dam to gain land, so that the water is then pumped outside and the soil is kept dry permanently with a drainage and pumping system, so that the land created remains below sea level. Less sand is needed, but it requires sophisticated and permanent hydraulic engineering. In any case, gaining land is increasingly expensive, complex and more delicate from an environmental point of view. Polder operation diagram. Dutch Water Sector Megaprojects to gain land. It is enough to look at a satellite map of the south of the country to see geometric shapes that do not exist in nature and that are geographical proof of their projects. And more specifically, a glimpse of some of the most impressive: Pulau Tekong. The best example of a polder is this project started in 2008 and completed in September 2025 from the hand of the Dutch Deltaresinvolved the recovery of 810 hectares of land located 1.2 meters below sea level. Jurong Island It is today a petrochemical hub, an industrial estate that was born from the merger of seven islands: Pulau Merlimau, Pulau Ayer Chawan, Pulau Ayer Merbau, Pulau Seraya, Pulau Sakra, Pulau Pesek and Pulau Pesek Kecil. Long Island It is his most ambitious and futuristic project. It will join three strips of land in the east (from Marina East to Tanah Merah) to gain 20 kilometers of coastline and about 800 hectares. How to gain water. Singapore’s water strategy is an absolute global benchmark and is carried out by the National Water Agency. Its strategy is articulated around four sources of supply (its four national taps): water from the local basin, imported water, desalination and NE water (from NEWater). The idea is simple but effective: diversify supply sources as much as possible so that, no matter what happens, the city’s supply is not compromised. And that no drop of water leaves the cycle without being reused. The first two consist of the local capture of rainwater in its network of 17 reservoirs and the agreement with the State of Johor (Malaysia), which began in 1962 and expires in 2061. For desalination they use reverse osmosis through membranes and have five plants in operation. But he tap More interesting is the NEWater, capable of covering 40% of the total demand of the country. How do they do it? With a three-stage treatment consisting of microfiltration, reverse osmosis and disinfection. The resulting water is so pure that it is used for industrial and cooling purposes. Megaprojects to gain water. Although we have already outlined the main lines of Singapore’s water strategy, there are truly impressive specific projects: DTSS (the deep tunnel sewage system): is a huge underground network for wastewater management 206 km long that is centralized in three recovery plants in Changi, Kranji and Tuas. The recovered wastewater is what is then passed to NEWater. Marina Barrage. A project that serves to get an idea of ​​the Singapore mentality: it is a reservoir built in the center of the city thanks to a 350-meter dam. It combines three functions: producing drinking water, keeping possible floods at bay … Read more

The internet has become obsessed with drinking hot water in the morning. Science is clear about what it does (and what it doesn’t)

by

We live in an age obsessed with ice. From the omnipresent iced coffee winter to complex viral drinks like sleepy girl mocktail that flood our social networks. However, in the midst of this liquid sophistication, the most revolutionary gesture for our gastrointestinal and mental health upon waking might be the simplest, most boring and cheapest of all: a glass of hot water. Faced with the inertia of an accelerated modern life full of stimuli, serving ourselves a glass of water at a pleasant temperature is presented as the first self-care gift that we can give to our body after emerging from the inertia of sleep. But what is the truth behind this practice? Is it an internet myth or a truth backed by science? The viralities of social networks. Just enter platforms like TikTok or Instagram to see thousands of influencers documenting how this morning habit deflates them, gives them energy and improves their digestion. As documented New York Timeshot water has become the new wellness superstar on-line. However, what the internet has dubbed a novel “longevity hack” is actually a fundamental pillar thousands of years old. This practice is deeply rooted in Indian Ayurveda (where the morning ritual is known as usha paana) and Traditional Chinese Medicine (TCM). In these cultures, it is believed that the cold turns off the agni (the digestive fire) and weakens the vital energy or Qiforcing the body to expend extra energy to warm the stomach. Hot water, on the other hand, balances the Yin and the Yangkeeping the body calm. Plain water, tea or infusions? When experts talk about this habit, they literally mean just that: water. Pasu Harisadee, traditional Chinese medicine educator, points out that “simple water is the most neutral base and the most recommended for most.” Of course, additions are allowed. Squeeze a little lemon provides vitamin C; add fresh ginger strengthens defenses and combats nausea; and a touch of honey can soothe the throat. However, the medical portal Verywell Health makes an important distinction versus tea or coffee: although infusions provide fluids, the caffeine present in coffee or certain teas has a slightly diuretic effect. Pure hot water is the undisputed champion of direct hydration. The golden rule and the temperature paradox. This is where medicine draws a non-negotiable red line: be careful not to get burned. Although some portals such as Healthline suggest that hot drinks They can be consumed in a range of up to 71ºC, oncologists and gastroenterologists are much more strict. As a study published in Frontiers in Nutritionconsuming drinks over 60ºC (140ºF) on a regular basis is associated with an increased risk of esophageal cancer, in addition to damaging oral tissues and burning taste buds. The ideal temperature should be lukewarm or comfortingly hot, never smoking to the point of burning. As Helen Ruckledge summarizes, nutritionist: “A tip: if you choose hot water, boil it and let it cool instead of drinking it directly from the tap.” The science behind. The core of this debate lies in separating magic from physiology. And in this area, experts have very clear positions: Intestinal hygiene and digestive “awakening”: This is the most supported benefit. Ana Luzón, Nutrition and Dietetics technician, explains in ABC which is about pure “mechanical efficiency”. Our body is at about 37ºC; Introducing ice water suddenly means a little thermal stress. Hot water acts as “intestinal hygiene”, dissolving food remains and mucus. For her part, Dr. Lisa Ganjhu, a gastroenterologist consulted by The New York Timesillustrates it perfectly: during the night, the digestive system is paralyzed. Hot water generates waves of contraction and relaxation in the muscles of the esophagus, stomach and intestines. “It’s basically telling everyone, ‘Okay, get up. We’ve got to get going,’” he says. This natural lubrication is key to combating morning constipation. Achalasia relief: To give it a deeper medical dimension, hot water is particularly useful for people who suffer from achalasia, a rare disorder that makes it difficult for food and liquid to pass into the stomach. Heat helps relax the lower esophageal sphincter, making the swallowing process easier. Relaxation of the nervous system: Holding and drinking a hot cup activates the parasympathetic nervous system, which is responsible for the “rest and digest” mode. This calms muscles, reduces tension, and relieves morning anxiety. Besides, a 1978 study already explained, the steam from hot water helps clear nasal congestion and relieves cold symptoms much better than room temperature liquids. Debunking myths: Neither ‘detox’ nor fat-burner. The big question that haunts the reels: Does hot water detoxify? No. Kristen Smith, nutritionistand Diane Lindsay-Adler, dieticiandetail that water does not magically eliminate toxins, the liver and kidneys are responsible for that. Hot water simply helps these organs do their job of filtering properly by keeping them hydrated. It is vital to compare this with dangerous internet methods. The obsession with do “detox” based on liquid diets or juices is a danger. A Northwestern University study showed that eliminating fiber living on juices for just three days is enough to ruin the intestinal microbiome. Hot water, on the other hand, is safe and assists the body without destroying the flora. Does it speed up metabolism and lose weight? Neither. There is no solid scientific evidence that it acts as a fat burner. There is a very brief metabolic cost while the body adjusts the temperature of the liquid, but it will not cause you to lose weight. The temporary weight loss that some notice on the scale is due, purely and simply, to the fact that the hot water has helped them go to the bathroom. The other side of the coin. A good analysis is not complete without its counterpoint. When is it not a good idea to drink hot water? If your goal is pure rehydration (for example, after intense exercise), a 2013 study showed that fresh water (at about 16ºC, similar to that of the tap) is the most effective. Additionally, there is a curious paradox with sweat: drinking hot … Read more
