science explains what happens to your body (and your brain) depending on the time you choose

by

In social circles, the truth is that there are sometimes very interesting debates about common customs, such as whether it is better to shower first thing in the morning or just before getting into bed. Here, while there is a group of people who defend tooth and nail the revitalizing power of water in the morning to “start” the day, others say that there is nothing like hot water at night to conclude sleep. And here science has something to say. It makes us sleep better. If you have trouble falling asleep, the science here suggests that a nighttime shower may be a good idea, and explained in a meta-analysis published in 2019 in the magazine Sleep Medicine which analyzed 17 different studies. Here it was concluded that bathing or showering with hot water between one and two hours before going to bed reduces the time to fall asleep by approximately 36%. Because? Here hot water is our main ally, since it warms the skin and, therefore, increases blood flow to the extremities such as the hands and feet. From here, when you get out of the shower, that heat dissipates quickly, causing a drop in the body’s core temperature. And this is the key, because this thermal drop mimics the natural cooling that our body experiences before sleeping, which sends an unequivocal signal to the brain to release melatonin, which is the sleep hormone, and reduce levels of cortisol, which is related to stress. It depends on the time. From a psychological point of view, morning and night showers fulfill completely opposite functions and it depends precisely on the time at which we take them. In the case of the morning showerthe goal is increase performance with the activation of the sympathetic system by stimulating muscle tone and, above all, preparing us for the stress of the day. In the case of the night shower, as we have said before, an attempt is made to activate the parasympathetic system with a longer and more leisurely duration of the shower with the aim of reducing the accumulated physical and mental tension, fulfilling the function of an authentic ritual of transition and disconnection. According to psychology. Here we enter territory that is not so clear, but which indicates, for example, that people who prefer a shower at night do so because they have a lower tolerance for dirt, which is why they prefer to remove all the sweat of the day before going to bed. But it is also noted that people who prefer solitude tend to prefer nighttime showers, precisely because, after a day full of stimuli, the bathroom becomes a capsule of sensory disconnection. In the end, it is a way to relax from everything that has happened throughout the day. Images | freepik In Xataka | Cooling down is the forgotten step in our exercise routines. And that affects how we shower

The most predictable ocean system in the Pacific has collapsed for the first time in 40 years. And no one really knows why.

by

For the first time in at least 40 years of systematic records, the Gulf of Panama’s “seasonal upwelling” (the mechanism that pushes cold, nutrient-rich water from the bottom to the surface every first quarter of the year) collapsed in 2025. 2026, fortunately, is not repeating the pattern. But what researchers are discovering is no more reassuring. Has the outcrop “gone”? Not exactly: it didn’t completely disappear; but it started 42 days late, lasted only 12 days (compared to the usual 66) and cooled the waters to 23 degrees (instead of the average 19). And yet, it is counterintuitive. First, because La Niña (the ENSO phase that ruled in 2025) It usually favors blooms in the eastern Pacific. Second, because until now we thought that warming intensifies large outcrops. And, third, because the upwelling has returned this year (with some collapses in between). None of this fits with what we have learned over 30 years of direct ‘in situ’ measurements (and satellite images). But wait a second, what is this “outcrop” thing? It is an effect of the increase in intensity of the ‘Panama low-level jet‘; a jet that pushes surface water deeper and allows cold, nutrient-rich water from the depths of the Gulf of Panama to rise. This outcrop is key to the life of some 60,000 km2 of the Pacific. The fact is that it is also the most predictable system in the Pacific. Since we started measuring it, he had never missed his appointment. What happened in 2025. The allies did not have the strength to break the thermal stratification of the surface and, therefore, were not able to activate the outcrop other than as a simulation. And why should we care? To begin with because, according to the same researcherss, “more than 95% of Panama’s marine biomass comes from the Pacific thanks to the rise of nutrients”: that is 2.76% of the GDP of the Panamanian republic. But it goes beyond the Central American country: the upwelling areas occupy less than 1% of the world’s ocean surface, but They generate around 50% of fishing catches of the planet It also has an important oceanic and climate impact, of course; but it tells us very interesting things about what we can expect in the future. Because if, suddenly, a phenomenon that we thought was very stable (and that we have known about for as long as we can remember) can disappear, what can happen? What, in reality, is the Gulf of Panama telling us? Image | O’Dea et al. (2025) In Xataka | 2023 was the year in which El Niño and climate change competed. In the Amazon we already know who won

the last time all humans were on Earth

by

It sounds like the beginning of a work of science fiction, but it is a quiet milestone in the history of our species. On Tuesday, October 31, 2000 marked the last day in which every human being on the planet was on this side of the atmosphere. Since then, there has not been a single moment in which all of humanity has been confined to our home planet. A historic launch. That October 31, 2000, A Soyuz spacecraft took off from the Baikonur Cosmodromein Kazakhstan, carrying Expedition 1 of the International Space Station on board: American commander Bill Shepherd of NASA and Russian cosmonauts Sergei Krikalev and Yuri Gidzenko of Roscosmos. The crew arrived at a fledgling ISS on November 2, 2000. It only had a couple of modules (the Russian Zarya and the American Unity, assembled in 1998), but since then, the orbital laboratory has been occupied continuously. For 24 and a half years, there is always a human floating about 400 kilometers above our heads. A quarter of a century. The International Space Station is a collaborative project between five space agencies (the American NASA, the Russian Roscosmos, the European ESA, the Japanese JAXA and the Canadian CSA). It is not only a symbol of international cooperation, but an unparalleled scientific laboratory, which orbits the Earth every 90 minutes at a speed of almost 28,000 km/h. In this quarter of a century, the orbital station has reached a habitable volume greater than that of a six-bedroom house, with a wingspan of 109 meters and an average of seven people always on board. It can dock up to eight spacecraft simultaneously and has hosted almost 3,000 investigations from more than 108 countries, taking advantage of microgravity to study everything from particle physics to the effects of space travel on the human body. The ISS passes the baton. Aged and with age-related ailmentslike the air leaks that cause headaches for its operators, the ISS partners plan to abandon it in 2030, before a ship developed by SpaceX tow it to a safe place for atmospheric reentry. NASA’s strategy is clear: move from being the primary owner and operator to becoming a key customer, thus ensuring continued human presence in low-Earth orbit. This will allow further research in microgravity (which is crucial for future missions to the Moon and Mars), maintain international collaboration and foster a commercial space economy. USA announced last year its intention to reduce the budget allocated to the ISS hoping for a quick transition to new commercial space stations. Companies like Axiom Space (with its Axiom Sation project), Blue Origin (with its Orbital Reef) or Voyager Space (with Starlab, in collaboration with Airbus) are developing new private orbital platforms. What if they are not ready on time? If commercial stations do not arrive by 2030, humanity will continue to inhabit low orbit thanks to China. Banned from the ISS, China has expanded its presence in space with Tiangong space stationcontinuously inhabited since 2022. Not only does China plan to double its size from three to six modules in the coming years, but it is already opening its doors to international cooperation, as demonstrated by the recent agreement to train and send Pakistani astronauts to the Chinese space station. With NASA focusing on a business model and deep space exploration, Beijing is strategically positioned as a central player and potential alternative in low orbit, especially for nations seeking to collaborate outside the American framework. A changing environment. But there is another reason why the United States has focused on the Moon and Mars. Low Earth orbit faces the increasingly critical challenge of space debris. Millions of objects, from dead satellites and rocket upper stages to small undetectable fragments generated by collisions or anti-satellite missile tests. This debris travels at enormous speeds and represents a constant and potentially catastrophic collision risk for astronauts. The ISS itself has had to carry out numerous evasive maneuvers in recent years. Managing this problem through better tracking systems (especially for small objects), active removal of the most dangerous debris and, above all, prevention and mitigation in the generation of new space debris (such as rapid deorbitation of rocket stages) will be essential to ensure the safety of future crews in the long term. For now, and for just over 25 years, we continue to inhabit the space. October 31, 2000 was the last day of an era in which humanity was anchored exclusively to the Earth. Since then we have been, without interruption, a species with an extraterrestrial presence. Human permanence off Earth seems assured, but its sustainability will require even more effort and global cooperation.

Malaga had some enviable rustic plots. Now you have a time bomb with 167,000 tons of debris and asbestos

by

The volume of the figures is scary. According to official data from the Ministry of the Interiorthe Civil Guard has uncovered the illegal dumping of 167,000 tons of waste from construction works within the framework of what is called “Operation Cover”. This macro-operation has so far resulted in the investigation of twelve natural persons and three legal entities, all of them strongly linked to the construction and earthworks sector. They are accused of alleged crimes against the environment for systematically evading all legal controls required for the treatment of this waste. The trap of economic profit. Why was this location chosen? The answer, as is usually the case in environmental crimes, lies in economic benefit. As the environmental technical magazine explains Rethemethose investigated used rustic plots located in the Axarquía region to convert them, de facto, into clandestine landfills. The objective was purely lucrative: to avoid at all costs the payment of the corresponding fees for the treatment of this debris in duly authorized recycling plants. Behind the mountain of garbage. The problem is that it has become a critical focus for the residents of the area. According to what they warn from the Interiorthis negligence represents an enormous risk of fire due to the amount of flammable material that has been piled up. In addition, there is a real fear that toxic waste will seep underground and ruin the water in local aquifers. However, the most disturbing discovery in the area has been the appearance of fiber cement (asbestos) among the rubble. According to the local media South Journalimproper handling and exposure to the elements of this “highly dangerous” material causes the release of harmful fibers into the air, posing a direct and lethal risk to public health. The judicial future of operation “Cover”. With the damage already done on the ground, the focus now shifts to the courts. The police proceedings carried out have been handed over to the Environmental Prosecutor’s Office of Malaga, which will be in charge of leading the judicial procedure against the fifteen accused. However, the case is far from closed. The investigation carried out by agents of the Nature Protection Service (Seprona) of the Civil Guard remains open. The authorities have intensified surveillance in the province and it is not ruled out that new actions or accusations may occur in the coming months. The ghost of Nerja and urban pressure. This discovery in Axarquía is not an isolated case, but rather the symptom of a structural problem. local media provide fundamental context to understand the magnitude of the situation: the strong urban pressure in the province of Malaga and the immense volume of waste generated by brick greatly complicate control in rural and agricultural areas. Furthermore, what happened a few years ago with the illegal landfill in Nerja. In an old quarry located within a protected area (the Sierra Almijara natural park), more than 802,000 cubic meters of uncontrolled garbage accumulated over 18 years (from 1998 to 2016). Despite the obvious environmental catastrophe, the legal complexity of the matter led to all the accused, including businessmen and senior political officials of the municipality, being finally acquitted through sentences issued in 2023 and ratified in 2025. The bill we all pay. Hiding 167,000 tons of waste under the rural carpet of Axarquía is the empirical demonstration that the apparent economic “savings” of a few private companies ends up becoming a heavy and unfair toxic debt for the entire society. What was going to be a rustic plot dedicated to the land, today is nothing more than a time bomb loaded with asbestos, polluting liquids and flammable materials that waits under the sun for someone to finally assume the real cost of deactivating it.

The Spanish atmosphere has been loaded with fuel and now it’s time to pay the bill

by

Spain has been chaining one temperature record after another for a week and the culprit, as we have been explaining, is a subtropical ridge that the country has maintained between five and ten degrees above normal. Nothing particularly surprising, nothing that hasn’t happened two dozen times in the last few years. For complete the déjà vuIn fact, the same number has dragged a disproportionate amount of Saharan dust for days. And now, it’s time to suffer the consequences. Never corner a DANA. As I said, we can describe the third week of April with three words: heat, stability and suspended dust. But starting on the 23rd the situation changes and a trough is becoming detached from the general circulation and It is going to be configured in the form of DANA. The party starts here. The synoptic configuration is clear: a DANA in the southwest with the ridge still strong in the east and very warm air between the two structures. We have the basic ingredients of convection. What can we expect? AEMET forecast stormy showers locally stronghail and very strong gusts of wind in almost the entire interior of the Peninsula. Today, the highest risk areas are the west and center of the peninsula (Extremadura, Castilla-La Mancha, Castilla y León, western Andalusia), the Pyrenees and the Iberian System. If everything continues as it is, April will end up as the third warmest month on record and all that atmospheric energy will be channeled over the land. To put it in perspective: all this is going to cause average temperatures to drop more than 14 degrees in a matter of days. What does the heat have to do with the storm? Physicists use the Clausius-Clapeyron equation to explain that the atmosphere’s capacity to retain water vapor grows by approximately 7% for each degree of warming. The hotter, the more water vapor; more water vapor, (if the conditions are right) wilder storms. It is true that we are experiencing an unusual April… but the average temperature in Spain has risen 1.69 °C between 1961 and 2024 and heat waves last three days per decade. That is, the “outside the norm” in this case It means things are changing. and what we are going to experience (the passage from the 36 to the flood) is the new normal.

Millions to protect a war frigate. A Bluetooth tracker worth a few euros has been enough to follow her in real time

by

Protecting a warship costs a fortune. We are talking about sensors, protocols, personnel, weapons and a security chain designed to minimize any unnecessary exposure. That is why what has happened with the Zr.Ms. Evertsena frigate of the Netherlands Navy integrated into the battle group of the French aircraft carrier Charles de Gaulle. According to Omroep Gelderlandtheir position could be tracked in real time for hours with something much more mundane and cheaper: a simple Bluetooth tracker sent via military mail. The story does not begin with a technological gap or with a particularly complex maneuver, but with something much more earthly: a postcard. That was what the aforementioned medium used to introduce the tracker into Evertsen through the military mail service. The sources do not specify what device was used, beyond describing it as a low-cost tracker. It is easy to think of a Apple AirTagbut there is no indication that it was that specific model and the market offers many similar alternatives. How a minor failure left a frigate exposed The case gains another dimension when you look at what Evertsen’s mission was at that time. According to the source, the frigate was part of the group that escorted the Charles de Gaulle and its function was to help protect the aircraft carrier of possible air or missile threats. This task makes its location especially sensitive data within an ongoing military mission. In other words, it was not just about knowing where a ship was, but about being able to keep track of a relevant piece within a real operation. The really delicate thing about this episode is not only that a tracker managed to enter the military postal circuit, but what that suggests about certain procedures that continue to operate with a logic from other times. According to the media itself based on official videos from the ministry, the packages did go through X-rays, but the envelopes did not follow the same control. That combination opened enough of a gap to compromise the discretion of the deployment. We are not facing a spectacular failure, but rather an apparently minor vulnerability, but sufficient to allow the ship to be monitored. Once the initial filter was passed, the case stopped being a hypothesis and became a real follow-up. According to the reconstruction published by the Dutch media, the tracker signal made it possible to follow a path that went from Netherlands to Cretewith steps through Den Helder and Eindhoven airport before reaching the port of Heraklion. There, in addition, images from a camera fit that clue and showed the Evertsen moored at the dock. On March 27, once out of port, the frigate continued broadcasting its position for about 24 more hours: first it skirted the Cretan coast and then headed east, until the device stopped giving a signal near Cyprus. The official reaction came after publication and was, at least in part, corrective. The Dutch Ministry of Defense made changes following this incident and stopped allowing battery-powered greeting cards to be sent to Evertsen, as well as announcing a broader review of military mail guidelines. At the same time, the department held that the tracker was located while the correspondence on board was being sorted, once the frigate had already left the port. And although he admitted that the ship could be followed at sea, he assured that this did not constitute an operational risk. There is a quite obvious reading in closing this story. The frigate was still part of a military mission, protected within a much larger device, and yet a low-cost domestic object managed to open a tracking window for hours. Not because it replaced the big threats, but because it slipped through a minor seam that no one had fully adjusted. That’s what makes this episode especially revealing: remember that, in 2026, security doesn’t just depend on large systems.

More than 2,000 years ago, people were already taking to the grave the greatest “bestseller” of all time: the ‘Iliad’

by

No matter how many centuries pass or where they dig their shovels, the soil of Egypt remains a box of surprises for historians. Just checked it a team of archaeologists who have found a surprise when exploring an ancient necropolis from the Roman era of Al-Bahansalocated almost 200 km from Cairo. In addition to mummies, vessels with ashes and amulets, the researchers located one of the largest bestsellers of all time: the ‘Iliad’. The question is… What was he doing there? In a place in Minia… The news has taken care of advance it the Ministry of Tourism and Antiquities of Egypt, which gives an idea of ​​the relevance that the country gives to the discovery. An archaeological campaign led by doctors Maite Mascort and Esther Ponce has discovered mummies and funerary offerings in a necropolis from the Roman era of Al-Bahansa (Minia), the ancient Oxyrhynchus. The site is not exactly new. In fact, the Government speaks of two parts of the necropolis: number 65 and number 67, a Ptolemaic burial. located in 2024. The tombs were also not spared from grave robbers, who once damaged the coffins and probably took valuables with them. Still, the Spanish-Egyptian mission has made interesting discoveries. To the other world with Homer. Perhaps the most fascinating is the one found inside one of the mummies from the Roman period. When examining the body, the archaeologists extracted a papyrus with a fragment of the ‘Iliad’, the universal work attributed to Homer. To be more precise, they identified the passage ‘Catalogue of Ships’from the second book of the Greek epic and which describes part of the Achaean forces deployed in the Troy campaign. “This discovery adds a literary and historically significant dimension to the site,” they celebrate from the Egyptian Ministry of Tourism. Gold leaf and decorated linen. It was not the only surprise that archaeologists got when exploring the tomb no.65. The necropolis preserved several mummies from the Roman era carefully wrapped in linen decorated with geometric motifs. Even the polychrome wooden coffins and the fragments of gold leaf that were attached to some of the corpses are preserved. Tongues of gold and copper. It was not the only thing that the archaeologists found. When exploring the hypogeum, the researchers located three languages made with gold and a fourth made with copper next to the mummies that were still preserved in the funerary chamber. These were probably mortuary amulets that were placed in the mouths of the deceased to facilitate their journey to the Hereafter. Why is it important? Beyond how curious they may be, the findings are valuable for two main reasons. To begin with, as has been responsible for highlighting the head of Archeology and Tourism, Sharif Fathi, confirm the wealth and enormous diversity that accumulated in the Egyptian civilization over the centuries, including the Ptolemaic era and the domination of Rome. Furthermore, the mummies and other vestiges offer a valuable clue about the funerary practices used in Al-Bahansa in Greek and Roman times. Vessels with ashes. When exploring the east of tomb No. 67, from the Ptolemaic period, the archaeologists found a ditch with three limestone chambers in which they were still preserved. historical treasures. For example, in one of the rooms they located a stone slab and a vessel with charred remains that seem to belong to an adult, in addition to the bones of a baby and the head of a feline. All carefully wrapped in fabrics. In the second chamber there was also a container with the remains of cremated people and an animal of the same species. Statues representing the god were located in the surroundings. Harpocrates and even a figurine of the god Cupid.

Clint Eastwood filmed in Spain for the first time in 1964 and the impact was lifelong

by

In 1964, Clint Eastwood agreed to travel to Spain to shoot a low-budget film that, in his own diagnosis, “was probably going to be a total failure.” What he found when he arrived (an international team in perpetual chaos, actors and director unable to understand each other without an interpreter, a tree stolen through deception and a crane obtained thanks to a bishop) only confirmed his worst suspicions. Several decades later, he still remembered it. For a handful of pesetas. ‘A Fistful of Dollars was not a high-risk project, but quite the opposite: it cost around $200,000, co-financed by Italy, Germany and Spain, and Eastwood (then a television actor with no relevant film credits) was paid $15,000. Sergio Leone did not even sign his name: in the credits he appears as “Bob Robertson.” Ennio Morricone, as “Dan Savio.” Why Spain. The choice of Spain was not an aesthetic whim. The Franco regime had been facilitating the presence of foreign productions in Spanish territorypartly because of the economic benefits and partly because the presence of international stars served to soften the external image of the dictatorship. And for the production companies it was a bargain: the costs were much lower than those in the United States, the army provided extras when necessary and the landscape of Almería (one of the poorest provinces in the country, with very high unemployment) functioned as a perfect substitute for the American West. A single hat. Conditions on the set were, to put it mildly, spartan. There was no electricity or trailers with basic services and Leone and Eastwood did not speak the same language (one Italian, the other English), so they communicated through specialist Benito Stefanelli. Filming was done completely without sound: this was added in post-production, and Eastwood did not dub his own voice into English until the film was released in the United States in 1967. Your own clothes. Eastwood himself explained in 2007 who arrived with his own wardrobe to the filming: the black jeans he had bought on Hollywood Boulevard, the boots he brought from the series ‘Rawhide’ and the hat he got in Santa Monica. They bought the poncho in Spain. And that hat, unique and irreplaceable, sums up the project’s production philosophy well: “If I lost it, it was finished. There was no way to replace it.” They don’t shut up, they don’t shut up. What caught the most attention, however, was not the material precariousness but the atmosphere: off-screen people were playing frisbeetold jokes, talked non-stop. “They were not used to the silence of a shoot, where sound is important,” he recalled. He ended up using the need to play his part in the middle of that revelry as an exercise in concentration. There is no tree. Decades after filming wrapped, Eastwood still remembered two anecdotes as if they had happened weeks before. The first happened when they needed a specific tree for a hanging scene, they couldn’t find a suitable one and the only one available was on private property. Leone counted that the technicians convinced the owner that the tree was dangerous. In the version that Eastwood told in 2007, the alibi was different: they introduced themselves as highway department workers. There is no crane. The second anecdote that Eastwood remembers is from the filming of another film, ‘Death Had a Price’. The team needed a crane that they couldn’t afford. A company near the filming location had one, but it was a religious holiday and that company could not work. Leone went to see the local bishop and explained that his company was Jewish and therefore not subject to the Catholic holiday, so the bishop gave him permission to work. With that permit in hand, he went to the company with the crane: they couldn’t use it that day, but the Italians could, and they lent them the material.

Meta will surpass Google in digital advertising for the first time in history

by

That Google is the queen of online advertising is one of the great constants of the Internet, but everything indicates that the reign is approaching its end. If the predictions come true, for the first time in history, Meta will be the company that generates the most advertising revenue. Projections. At the moment the surprise has not occurred, but the projections of the advertising analysis firm Emarketer are clear: Meta is going to snatch the throne of online advertising from Google in 2026. Specifically, they project that Meta will earn 243.46 billion dollars from advertising, while Google will earn 239.54 billion. Why is it important. Google’s dominance in the online advertising market was absolute. In fact, that domain has been in the regulators’ crosshairs for years and It has become very expensive for Google. Meta’s surprise, although not by a huge difference, is confirmation that the internet has been reconfigured with social networks and that the cake is much more distributed. Considering that Google has built its empire on the foundation of online advertising, it is even more relevant. The Meta Boost: AI. Meta has a portfolio of products with millions of users such as Instagram, Facebook, Threads and WhatsApp. According to Emarketer, the company has been “incredibly patient” in building solid usage habits in its user base before introducing ads. But what has caused this acceleration has been the integration of AI in content recommendation systems. This has allowed them to increase the viewing time of Reels by 30%, which translates into more advertising and therefore more income, specifically they are expected to reach the 50,000 million only with Reels. Goal Advantage+. It is the suite with AI that Meta offers advertisers. In addition to offering the platform to advertise, Meta also provides a ton of tools ranging from advertising actions to the creation of the ads themselves with generative audio, text and video AI. According to the brand’s results, revenue from video generation reached $10 billion in the last quarter of 2025. It was seen coming. It is not something that happened overnight, but rather The change has been in the works for years.. The displacement of searches was moving to other specialized platforms such as Amazon, Instagram or TikTok. With the emergence of AI, the landscape has become even more fragmented: with chatbots that provide answers to many user queries without us going through the classic search engine. Google is no longer the ‘default’ when doing a search, especially for younger generations who prefer audiovisual content. OpenAI enters the business. A few days ago we talked about OpenAI’s ambitious plans for its newly launched advertising business. The company hopes that, by 2030, they will have generated $100 billion with ads on ChatGPT, that’s nothing. It is still a much smaller amount than those managed by Meta or Google in a year, but it is enough for the impact to be noticeable. With social networks the exodus of searches began and perhaps we are facing the second great displacement. Time will tell.

We believed that procrastination was a time management problem. Neuroscience has shown that it is a survival instinct

by

Almost all of us have been in the situation of being faced with a task that must be done no matter what, such as studying an exam or handing in an assignment. We know that it is something important, and that we should start addressing it now, but suddenly we are doing something totally different and insignificant like reorganizing the drawer or watching a video on YouTube. What seems so common is what we call procrastinationand we understand more and more why we do it. The context. For decades, popular culture has told us that procrastination is a time management problem or, worse yet, simple laziness. However, neuroscience has a very different message when it points out that procrastination It is not an organizational failure, it is a crisis of emotional regulation. The brain. To understand procrastination, we must first look at the anatomy of our brain, which often functions as a large battlefield divided into two sides. On the one hand we have the limbic system, which is one of the most primitive parts of the brain and whose function is simply to keep us alive, away from pain and seeking immediate pleasure. On the other hand, we have the prefrontal cortex, which is the most evolutionarily ‘modern’ area, located right on the forehead. This is where we have rational thinking, long-term planning and logic. What is known. Already a 2021 review pointed out that these areas are activated when you have to do a task that generates anxiety, boredom or insecurity, such as studying an exam. And it is no wonder, because the limbic system detects this situation as a “threat”, and automatically hijacks the prefrontal cortex to prioritize immediate emotional relief by looking at Instagram over the long-term benefit of starting to study to pass. We know more. Now, this year, a new study has taken a new step to understand this brain system, by identifying in primates a specific neuronal circuit that functions as a “brake” for motivation, and that connects two parts of the brain: the ventral striatum (VS) with the ventral pallidum (VP). The researchers discovered that when we face tasks associated with discomfort or the possibility of failure, this VS-VP circuit is activated, inhibiting the action, as if it were an emotional protection mechanism taken to the extreme. The most striking thing about the study is that, by interrupting this circuit in the laboratory, the subjects immediately restored their motivation, “releasing the brake” and tackling the difficult task. It’s not laziness. This new line of research is consistent with previous research that associated procrastination with stress, fear of failure, and anxiety. In this way, when seeing a blank document or a very complex Excel sheet, the amygdala activates a flight response. In fact, it has been seen that chronic procrastinators tend to have worse connectivity between the amygdala. the anterior cingulate cortex, which makes them less able to filter negative emotions and distractions. In short, the brain will procrastinate to protect itself from the psychological discomfort caused by a task. Hacking. Seeing how complex this all is, blaming yourself or calling yourself “lazy” is of no use. But it is true that you have to follow a strategy to be able to hack our perception of stress and reward, starting to break up the work, making it so that, instead of setting out to “write the entire work”, you should opt for “write only the title and the first paragraph for five minutes” to trick the amygdala. It is also possible to block sources of easy dopamine with a blocking system on your computer or mobile phone that makes it difficult to access Instagram or YouTube to watch a video. This way, if the immediate reward requires an effort like going to the next room for the phone, the prefrontal cortex has time to intervene and put us in concentration mode.
