While France freezes, Greece is at 27ºC in the middle of January

by

While Spain was preparing to live the coldest Twelfth Night in 40 years and Western Europe collapsed in the face of a cold and snow stormthere are parts of Europe and the Mediterranean basin that They are practically in summer. And no, it is not a figure of speech: during last nightthere were people on the Greek island of Crete sleeping with air conditioning. What has happened? “35 degrees in Algeria, 20 in Russia, tropical nights in Greece, records throughout the central and eastern Mediterranean from Algeria to Turkey (with the only exception of Italy)”, said M. Herrerameteorologist specialized in extreme events. But what is striking is not the description, what is striking is what it means. Because the map that heads this article is not one of absolute temperatures, but of anomalies. And that can obviously distort the matter a bit. However, the absolutes (with data from the Greek National Observatory in Athens in hand) are amazing: we are talking about 27.5 degrees last night in Falasarma and 25.3 in Neapolis. At night. That is, we are talking about temperatures similar to those of August. Or worse because, indeed, we are in January (as the rest of Europe is suffering) The warmest night in Europe while part of the continent remains isolated under snow? It seems so. And not only because of the specific data (it is possible that the record for the warmest night in Greece will not be surpassed: Falasarna suffered one night at 28.3 in 2021), but because but because the heat is as widespread as snow in the West. We have seen night temperatures of 16 °C in Sevastopol (Crimea) and 13 in Tuapse (Russia). Furthermore, if everything continues as expected, there will be nights at 20°C in the Russian Caucasus and above 25°C in Turkmenistan and the Caspian coast. A real madness that, If Herrera is rightwill go down in the climatic annals of the continent. The image of a Europe divided in two is tremendous. But the question is why. And the answer is simple: an extremely wavy ‘jet stream’. We already know that the jet ripples, but rarely can you see an ‘S’ of this size. While in the west the atmospheric circulation introduces arctic air; In the east, a gigantic ridge favors south-southwest winds. The wavy structure of the jet is pumping polar air into France and Saharan air into Greece. Then local effects exaggerate the anomaly. In Spain, for example, thermal inversions place us at -14 degrees, while in Crete the subsidence causes extremely hot and dry air.

he left everything agreed after the Second World War

Of all the possibilities that are being heard about “the Greenland thing”one, possibly the most plausible, is getting lost in the conversations. No money, no political pressure, not even the “military option”. If the United States wants something in the Arctic, it only has to turn to an old and little-known Cold War pact. There is no need to buy what you control. The Donald Trump’s obsession “buying” or even “taking” Greenland is actually based on a false premise, because for more than seven decades the United States has already had a freedom of military action extraordinary without the need for formal sovereignty, something that turns his recent threats more into a political gesture than a real strategic necessity, despite the fact that he justifies them in terms of national security and the presence of Chinese and Russian actors in the Arctic. The 1951 agreement. The core of this situation is in the defense agreement signed in 1951 between the United States and Denmark, which gives Washington the right to build, operate and maintain military bases throughout Greenland, deploy personnel and control air and maritime operations, a scope so wide that Danish experts recognize that, in practicethe United States can get almost anything it wants simply by asking for it, without resorting to annexations or impossible purchases. From WW2 to the Cold War. The origin of the agreement dates back to Nazi occupation of Denmark during World War II, when fear that Germany would use Greenland as a platform to America led to a defensive pact which allowed the United States to expel the Germans and build more than a dozen bases on the island. That presence that remained during the cold war through radars and early warning systems and which today focuses on strategic Pittufik Space Basekey to tracking missiles over the North Pole. Headquarters of the Schalburg Corps, a unit of the Danish SS, after 1943. The building occupied was the lodge of the Danish Order of Freemasons located on Blegdamsvej, Copenhagen. Why buying is impossible. Beyond the military, the idea of ​​buying Greenland collides with a clear political and legal reality: Denmark cannot sell it and the Greenlanders themselves, who today have the right to decide their future through referendumthey overwhelmingly reject any US takeovera position reaffirmed by his prime minister and backed by polls showing massive opposition to a Washington takeover. The 2004 amendment. The defense agreement was updated in 2004 to explicitly recognize Greenland as an equal part of the Kingdom of Denmark and force the United States to consult on any significant changes to its military operations, a requirement that, according to Danish analystsworks more as a diplomatic courtesy than as a real brake, since if Washington wanted to expand its presence it could do so immediately without violating the existing framework. Trump, Venezuela and escalation. The recent American coup in Venezuela and the capture of Nicolás Maduro seem to have emboldened Trump and his entourage, who talk about Greenland as if it were an inevitable lootprovoking an angry reaction in Copenhagen and Nuuk, where it is warned that any attempt at occupation rempire the international orderwhile European leaders remember that the legal framework already gives the United States everything it needs without resorting to threats. It’s all about minerals and the Arctic. It we counted yesterday. Beyond military geopolitics, Greenland attracts for its enormous reserves of critical minerals and, very importantly, for your key position in an increasingly navigable Arctic, although even here experts agree that the United States does not need to control the territory to access those resources. The reason is simple: Greenlanders are open to doing business with anyone… as long as their sovereignty and right to decide are respected.

Samsung has tripled its profits

by

The madness with the RAM memory prices is conditioning how the PCs that are sold are assembledthreatens with increase in the price of mobile phones and there is even talk that Mobile phones with 4GB of RAM are coming back. But what is bad news for the vast majority is excellent news for a few, and there is a clear winner. Samsung is getting rich. Samsung has published the fourth quarter 2025 results and the figures make it clear that if there is a winner in the problem of RAM prices, it is them: Operating profit for the quarter was $14 billion, a year-on-year increase of 208%. Compared to the previous quarter, operating profit has increased by 64.3% and revenue has increased by 8.1%. It sells more, but above all it sells more expensively. If we look at the photo of the full year, Samsung has earned 33% more than in 2024. Why it is important. Samsung consolidates itself as a leader in the memory sector and enters a phase of extraordinary profits. Is the technology company that has appreciated the most in 2025, with a growth of 123.11%, all driven by the very high demand for memory to meet the needs of AI. The best option. Samsung shares They have risen almost 30% in the last month and 1.8% after the results were announced. The excellent results and valuation place Samsung in a very advantageous position in the market. According to Macquarie analysts “We did not find a better option than Samsung in the entire AI supply chain.” HBM. Seizing the moment, Jun Young-hyun, head of the semiconductor division, has assured that they hope to catch up with SK Hynix in advanced HBM chips, which are a key component in data centers. Samsung already announced its HBM4 chip a few days ago and its objective is clear: to once again be NVIDIA’s number one supplier. Unstoppable escalation. According to the latest report of Counterpointthe memory market is in a hyper-bullish phase. At the end of 2025, prices rose by 40-50% and another similar increase is expected in the first quarter of 2026. For the third quarter, they talk about 20% more. In other words, a 64GB RDIMM module (used in servers) cost $255 in September 2025, rose to $450 at the end of the year, and will cost $700 in March of this year. 1,000 dollars. The border of $1,000 is not that far away and reaching it seems feasible given that analysts predict that the situation It will continue throughout 2026some even point out that extends until 2028. If reached, it would be almost double what it rose in 2018 when another price peak occurred. No low prices, thank you. The insatiable demand for AI is causing shortages, which in turn are causing prices to rise. A possible solution would be to increase production, but Samsung and SK Hynix flatly refused arguing that there is a risk of overproduction. Currently, Samsung is only managing to fulfill 70% of DRAM orders. Looking at the numbers, it is clear that it is profitable for them.

Ouigo and Renfe unleash a price war like we have not seen in a long time

by

Who was going to tell us 20 years ago that we would change the traditional races at the doors of El Corte Inglés on January 7 to burn the F5 on the Renfe website. Or, much more inconceivable, that of another French company that was going to compete with the public company to take us on high-speed trains through our country. However, this is how we are. January sales. Since yesterday, January 7, Ouigo has put it up for sale train tickets at reduced prices. So reduced that it is possible to find options for nine euros because 80% of the available tickets are discounted. The maximum price of these tickets is 33 euros. The offer will last until next January 14th… as long as there are tickets available. An almost carbon copy maneuver Renfe has undertaken. Since January 8, the Spanish company has opened juicy discounts on its train tickets. In this case, the offer extends until January 18 on AVE, Avlo, Alvia, Intercity, Euromed and AVE Internacional tickets, but it is not specified how many tickets are available with discounts that offer AVLO tickets at seven euros and AVE tickets at 15 euros. CNMC source: https://www.cnmc.es/sites/default/files/6291881.pdf New year, cheap trains. It has been a constant since competition entered the Spanish railways. Train prices in our country plummet every beginning of the year, as shown in the graph above referring to the Madrid-Barcelona corridor from the Railway Traveler Report presented by the CNMC every quarter. The image above refers to the most used broker in our country and, therefore, the least susceptible to price changes. Obviously, the image is repeated on trips to Andalusia or the Levant. Thus, all companies lower prices with juicy discounts at the beginning of the year. Then they rise due to Easter and the arrival of summer and suffer a small drop again in the third quarter before picking up again at the end of the year. It repeats. If we take a look at the report that collects data from just one year ago, we see how the number of passengers has been increasing in recent years but that prices had to drop to transport a passenger with fewer incentives to move in a quarter without major holidays and worse weather prospects. That made it so that in 2025, according to data from the CNMCin the first quarter of the year, AVE prices fell by 9.2%, Iryo prices by 11.2%, Ouigo prices by 16.1% and AVLO prices by 19.5% compared to the previous quarter in the Madrid-Barcelona corridor. And December is one of the most expensive months of the year to buy tickets and this is repeated in all corridors. With leaden feet. Although the offers are attractive, we must not lose sight of the fact that it is a specific ticket sale and that what sets the trend is the average price at which most tickets are sold. And the last few months tell us that ticket prices are going up. This quarter’s performance is something we will have to wait to find out but if we look at last year’s data from the same Madrid-Barcelona corridor, only Iryo lowered prices in a representative manner when compared to the previous year. It did so by 5.4%, followed by AVLO which lowered prices by 3.9%. However, the AVE only fell by 0.9% and Ouigo raised prices by 5.6%. On average, the price only fell by 0.9%. It is true that in the Andalusian corridors and in Madrid-Valencia, prices fell significantly last year, with drops in the average ticket price of between 10 and 17%. Of course, it must be taken into account that these are destinations where the seasonal influence is more pronounced than in Madrid-Barcelona, ​​a more stable corridor in passenger volume. Fewer offers and more profitability. We give this notice because in recent times we have seen how the prices of Spanish trains have been rising. According to the latest report from the CNMCwhich refers to the third quarter of 2025, the average interannual price of this period increased by more than 25% in Madrid-Barcelona and remained more or less stable in all corridors except Madrid-Málaga, which Until last year it did not have the Ouigo factor. However, from all companies they have paved the way so that we get the idea that the price is going to rise. So much Iryo as Ouigo They have announced that they are ending losing money to enter a new market. Both have made changes in management and from Renfe they have warned that If the competition raises prices they will follow.

The V16 beacon sold by Carrefour drops even further in price. It is made in Spain and comes with its own app

Although there are many V16 beacons that allow us to comply with DGT regulations, personally there are only two that I would buy for what they offer: the Help Flash IoT+ and the LEDOne. In both cases because of their number in candles and because they connect to their respective apps. Of course, the latter is now more attractive to me than the first, since Carrefour has lowered its price to 29.99 euros. The price could vary.

We saw one of its highest prices before the end of 2025 and it reached 49.95 euros, so if you still do not have one of these beacons or are looking for an additional one, it may be interesting. The LEDOne is a connected V16 beacon that visually stands out for its format, very different from what we usually see in other brands. Includes a base that raises the beacon itselfa point that may be interesting when placing it in different vehicles. Regarding its technical sheet, the LEDOne offers, according to the brand itself, 120 effective candleswhich is interesting in order to have better visibility than with the minimum required by the DGT itself.

It has become a bottomless pit of people stripping women with AI

by

Since AI Grok has conquered what was once Twitter, the social network has become an infinite well of content generated by artificial intelligence. The problem is when that content is used to misinform or ends up harming other people. And today, Grok has become one of the main sources of sexualized images created without consent. Just like they count According to Bloomberg, the chatbot generated approximately 6,700 such images per hour during a 24-hour period in early January. The magnitude of the problem. On X there are many users who spend their time using Grok to modify photos that other people publish on the social network, generating versions in which they appear scantily clad or in sexualized situations. The middle appointment the findings of independent researcher Genevieve Oh, who identified that during the analysis carried out between January 5 and 6, Grok produced these images at a rate 84 times higher than the other five websites most active in this type of content. Oh estimated that 85% of the total images produced by Grok have been generated to sexualize. What’s special about Grok. Unlike other chatbots like ChatGPT, Claude either GeminiGrok doesn’t impose many limits on generating sexualized content from real people. Users can tag Grok’s account in replies to other people’s posts and request that he modify the original images. The most common requests include phrases such as “put her in a bikini,” “take off her clothes,” or “change her clothes to a see-through bikini.” The chatbot generates these images in a matter of seconds and publishes them automatically, linking them to the victim’s original publication. Victims without response. Maddie, a 23-year-old medical student cited per Bloomberg, woke up on New Year’s Day to discover that several strangers had altered a photo of her and her boyfriend using Grok. First they removed their partner from the image and put her in a bikini, then another user asked Grok to replace the bikini with dental floss. “My heart sank. I felt hopeless, helpless and just disgusted,” she said. When she and her friends reported the images through X’s moderation systems, they never received a response. In a different case, X determined that there were no “rule violations” in the reported content. According to the mediumthe images were still on the social network at the time of the publication of the report. Cases media. The problem has even reached public figures. And as they say from Guardianmultiple users asked Grok to alter an image of Sweden’s Deputy Prime Minister, Ebba Busch, to show her in a bikini. In addition to this, two British government ministers have also been victims of these manipulations. Eliot Higgins, founder of Bellingcat, a group specialized in investigative journalism, counted to the outlet how Grok responded to instructions such as “bikini now” or “put a bikini with the Confederate flag on her” over the photo of Busch in Parliament. Musk and X’s response. In the face of recent criticism, Elon Musk claimed in X that “anyone who uses Grok to create illegal content will suffer the same consequences as if they uploaded illegal content.” However, this strategy of punishing users instead of preventing the chatbot from generating the content appears to have proven ineffective. Just like they count From Bloomberg, when someone requests to remove those images in the comments, Grok often apologizes and says he will take them down, but in many cases the images remain and the system continues to generate new ones. Legality. Carrie Goldberg, attorney specializing in online sexual crimes, explained to the outlet that the scale of deepfakes on X is “unprecedented” and noted that the platform “is not acting as a passive editor. It is actually generating and creating the image.” In this sense, the Law Take It Downapproved in the United States in 2025, holds platforms responsible for the production and distribution of this type of content. Brandie Nonnecke, of Americans for Responsible Innovation, counted Bloomberg that platforms have until May 2026 to establish the required removal process. Increasingly widespread use. Although the technology to create sexual deepfakes is not new, as there are dozens of websites and Telegram bots dedicated to undressing people, the fact that this capacity is hosted by a social network as well-known as X marks a turning point. And unlike specific image manipulation services, Grok is free, produces results in seconds and is available to millions of users on X. Sloan Thompson, of the EndTAB organization, pointed out Wired said that “when a company offers generative AI tools on their platform, it is their responsibility to minimize the risk of image-based abuse. The alarming thing here is that X has done the opposite. They have integrated AI-enabled image abuse directly into a mainstream platform, making sexual violence easier and scalable.” Cover image | Tamara Bellis and Antonio Vallejo In Xataka | We are entering a new era of robotics driven by AI and Disney is its perfect showcase

Now a new “rival” has emerged in Morocco

by

Until a few days ago, the map of human evolution in Africa had a major “black hole” of knowledge. We had data that indicated that the Homo sappiens It emerged about 300,000 years ago thanks to the remains of Jebel Irhoud and we knew that our most distant ancestors ran around the continent a million years ago. But in the middle there was no information about it. A new study. To address this gap, an international team led by paleoanthropologist Jean-Jacques Hublin has published in Nature a discovery that not only fills that void, but also It forces us to recalibrate when and how we begin to be “us.” They have finished putting the focus on a quarry in Casablanca (Morocco) where the remains of what could be our oldest direct ancestors have appeared. A treasure under the quarry. This site is not entirely new, but what has been revealed is. In the so-called Grotte à Hominidés Researchers have been able to find three jaws (two from an adult and one from a child), isolated teeth, vertebrae and a fragment of a femur. This femur the truth is that It has a macabre history behind it, since it has marks of hyena teeth, which suggests that these individuals were not buried, but rather were the feast of the predators that lived in this cave. But the interesting thing about these remains is undoubtedly in their morphology, which presents very primitive features, but, at the same time, their teeth and the structure of their jaw show “derived” features that already point directly towards the Homo sapiens. Technology behind the date. In paleoanthropology the difference between an “interesting find” and a “revolution” usually lies in the dating of the discovery. Something that today can be done with great precision thanks to the combination of geology with modern techniques. In this case, the researchers used the technique of magnetostratigraphy to analyze 180 sediment samples to identify the Brunhes-Matuyama transition. This transition in the sediments is fundamental, since it is a global event that occurred about 773,000 years ago, when the Earth’s magnetic field was invested (magnetic north became the current geographic north pole), and which is useful for dating sediment samples. Its dating. By finding the fossils right in this stratum that we have so well studied along with when it occurred, we can now set a date of 773,000 years with a margin of error of just 4,000 years for these fossils. And although 4,000 years may seem like a large margin of error, the reality is that in geological terms it is like telling the time in a very exact way (even with its seconds). The end of the reign of Atapuerca. For years, the Homo antecessor from Atapuerca (Spain) was proposed as the common ancestor of sapiens and Neanderthals, to make sense of this void. But this discovery completely changes the narrative we have on the table. Hublin’s study suggests that these Moroccan hominids are evolutionarily closer to us than the Homo antecessor. In this way, while the Spanish fossils seem like a lateral branch that adapted to the European environment, those from Casablanca would represent the main African lineage. Something that also fits with current genetic studies that place the divergence between modern humans and Neanderthals approximately 800,000 years ago. It doesn’t fit everyone. Like any great advance, this scientific article has raised a lot of dust in the sector, since not all experts are convinced that the origin is exclusively African. On the one hand, María Martinón-Torres, director of CENIEH, criticism The study ignores recent Asian fossils (such as those from Harbin or Hualongdong in China) that also show modern features at ancient dates. On the other hand, Antonio Rosas, from the CSIC, raises a reasonable doubt: If these fossils are close to the root of the common ancestor, why don’t they show traits that also point towards Neanderthals? What it means for the future. This discovery in Casablanca breaks the paradigm that the Homo sapiens It was a recent “invention” from 300,000 years ago. Instead, it suggests that it was a much longer, more complex and deeply rooted process in North Africa. What is happening right now is that Hubblin’s team is continuing to dig. With current dating technology and the possibility of finding more cranial fragments, the next step will be to try to extract ancient proteins from the teeth to confirm, through paleoproteomics, if the DNA confirms what already seems obvious: that the bones are older than we think.

How to safely defrost your car windshield glass

by

Let’s explain to you how to defrost your car windows quickly and safelywithout risking them breaking or having any damage. Because on these extremely cold days we may have to go out in the car and encounter this inconvenience. When this happens, we can be left not knowing very well what to do, especially when we are in a hurry. This can lead to dangerous mistakes such as using hot water or adding salt, which can damage the windshield. Therefore, we are going to try to give you several tips that are safe. Use the car heater This is perhaps one of the slowest methods, but it is the safest. Simply put the car in gear, activates the air conditioning heatingand put your car’s defogging mode so that the air flow goes to the glass. This will progressively soften the ice, something that It will make it easier for you to remove it with a cloth or scraper.. It may take several minutes, but it prevents the most damage to the glass. Use plastic scrapers There are plastic scrapers designed specifically for carsand to avoid damaging the windshield glass. These will help you remove the surface layer of ice with firm and smooth movements. You should avoid any type of sharp or metal scraper to avoid scratching the windshield. If the smell is very thick, you can combine the plastic scraper with the car heater from the previous point and with the defrosting liquid. Use deicing liquid It is also useful use commercial deicing liquids specifically prepared to melt ice. They are fast and efficient, and are formulated not to damage the glass or paint of your vehicle. This is the best solution, although in order to use it you must have remembered to buy this liquid and carry it in the car. If so, you just have to spray it on the windshield and wait a few seconds for it to work, and then scrape it off. Be careful with warm water When the car glass is frozen, the great contrast in temperatures resulting from pouring hot water can cause the windshield to break instantly due to thermal shock. But if you use warm water with caution, then it can serve. What you have to do is avoid making the water too hot, just lukewarm. Then, pour it slowly and evenly to melt the ice little by little. Always with care. In Xataka Basics | How to see the warnings for extreme cold and snow anywhere in Spain

turning ChatGPT into a pocket doctor

by

More than 230 million people ask ChatGPT questions about health and wellness every week. It is not an estimate, it is data from OpenAI published alongside the announcement of ChatGPT Healthyour new personalized section for medical and wellness consultations. ChatGPT Health. ChatGPT Health was presented just a few hours ago as a new section within the app, designed to go beyond the specific queries that users already made. The goal is more ambitious: centralize health data and medical history in a single place, turning ChatGPT into something closer to a health monitoring platform than a simple conversational assistant. How it works. Currently available for “a small number of early adopters” in the United StatesGPT Salud will be integrated as another section within the app. It will allow you to make queries like any other GPT, with some key points: We can integrate it with Apple Health (and all your data on mental health, steps, weight, heart health, etc.) We can integrate it with wellness apps like MyFitnessPal It is specially developed to upload our clinical history and most recent tests In detail. In addition to these integrations, ChatGPT Salud is designed to function as a healthy habits assistant. It will also be integrated with apps like Peloton to suggest classes or guided meditations, apps related to creating recipes like Instacart, or Weight Watchers to guide nutrition in GLP-1 medication users against obesity and diabetes. Why is it important. OpenAI works closely with health experts in the development of its models. Still, ChatGPT has not been without controversy, especially in the mental health space, where the model generated various criticisms and forced response guidelines to be adjusted in recent updates. The launch of GPT Salud is not a rectification, it is a declaration of intent: AI not only does not turn back in the clinical field, but rather aspires to consolidate itself as a “pocket doctor”, always available, increasingly integrated and with a growing role in everyday decision-making related to health. Yes, but. AI-fueled psychotic breaks, demandsand people asking ChatGPT how can you inject botox to herself. OpenAI makes it clear that ChatGPT health is not coming to replace your GP, but use the app as if it were He is a regular. Fairly recent surveys show that 17% of the adult population uses chatbots at least once a month to search for information related to their health. Dependency and retention. ChatGPT is still, by far, the most used AI chatbot in the worlddespite the advance of alternatives such as Google Gemini, DeepSeek or Grok. But OpenAI cannot rest on its laurels, and a of the best ways to stop the drop in users What Gemini is causing you is dependency and retention. ChatGPT is still by far the most used AI chatbot in the worlddespite the push of alternatives such as Google Gemini, DeepSeek or Grok. But OpenAI cannot afford complacency. The growth of Gemini is having an impact on retention of user (with a significant drop in GPT) and, given this, health is a clear winner. They are not one-off queries, they are recurring. By including clinical information, ChatGPT stops being a question and answer chatbot, it becomes a medical agenda. The health app market continues to grow in users, and integrating them natively into ChatGPT retains the user even more Image | Pexels In Xataka | ChatGPT is writing medical and economic studies.

Women consistently sleep worse than men. And science has finally discovered why it is

by

For years we have been able to have a perception in many homes: the women tend to sleep worse, wake up more and feel more tired than men. This is something that for a long time has been dismissed as a subjective perception, but Science has now wanted to close the debate, pointing out that it is not only a perception, but that there is a gender gap documented. The data. The Global Sleep Survey 2025carried out on a massive sample of more than 30,000 people in 13 countries, has produced a key figure: 38% of women have problems falling asleep more than three times a week, compared to 29% of men. Something that in Spain is not a very different situation, since according to the cross-sectional studies recently published in Naturewomen have much higher scores on the Pittsburgh Sleep Quality Index (PSQI), indicating worse subjective quality. In this way, while 44.6% of Spanish women report poor sleep quality, in men the figure drops to 30.1%. A paradox. Tests with motion sensors suggest that women sometimes have higher “sleep efficiency” on paper, but it is perceived as greater exhaustion. The person responsible for this is the sleep fragmentationwhich is related to constant waking up or even in mothers due to having to get up to care for a baby, for example. The hormonal factor. It is undoubtedly one of the big differences that exist between men and women, since estrogen and progesterone levels fluctuate drastically during the menstrual cycle, pregnancy or menopause. In the specific case of menopause it can be seen as a drop in the level of estrogen, in addition to produce alterations in bone formationalso increases the immediate degradation of rest. The data indicates that 51% of the Menopausal women suffer from sleep disordersshown a big difference: 44% of women in this stage report serious problems compared to 33% of non-menopausal women. If we go to pregnancywe see something similar with physical (from discomfort) and hormonal disruptions that create a pattern of alertness that often doesn’t fully recover until years after childbirth. The mental load. Beyond the hormonal load, the social factor is, perhaps, the most difficult to correct. One of the most important is the role that women have in many cases regarding the care of other people. According to the data compiled by the University of Michigan and diverse reviews on BMJ Openemployed women wake up twice as often as their partners to care for children or dependent relatives, even when they are the main breadwinners of the home. This “caretaker” role keeps the brain in an “alert” situation, making it attentive to whether a baby cries at night or a dependent family member has any need. This causes 76% of caregivers to report poor sleep quality.since the brain cannot unconsciously disconnect to monitor the well-being of the environment. Its consequences. Poor sleep not only means being tired the next day, but also has more serious clinical consequences. One of the most important is the increase in the probability of having a metabolic diseasesuch as diabetes. In addition, it increases accelerated cognitive deterioration and causes an increase in anxiety and depression disorders. And what is interesting in this case is that the female brain in sleep deprivation is more vulnerable to emotional dysregulation. The solution. The scientific community, from the Sleep Research Institute (IIS) to publications in Frontiers in Psychiatryagrees that it is not enough to increase “sleep hygiene” by leaving your cell phone before going to sleep, for example.
