Meta thought it was a good idea for its AI to generate images from your Instagram photos. Days later he has already turned back

Last week Meta launched Muse Image and Muse Video, its new AI models integrated into the Meta AI app. However, the launch was quickly overshadowed by the criticism he received one of the functions of the image generator. Within Muse Image, in addition to writing the normal prompt, Meta thought it was a good idea to let us tag other Instagram users to Generate images from your photos. All you have to do is type the at sign with your username and Muse Image can access your profile to create any image you can think of. The problem with all this is that Meta activated it by default for all public Instagram accounts, without warning or of course asking for permission. If you wanted to prevent anyone from tagging youyou had to manually disable it from your account settings. Meta backs off: they will no longer be able to tag us in Muse Image Muse Image was announced last Tuesday, July 7, and in the following days the criticism of this decision began to accumulate. Four days later, on Saturday the 11th, Meta issued a statement in which They responded to the controversy. According to Meta, their intention with the tagging feature was to “offer a useful creative tool” and “give users control over whether their public content could be mentioned.” The best way to give control to users would have been to let us activate it if we wanted to be tagged and not the other way around. Meta has confirmed that The labeling function has been removed. This is the full statement: Earlier this week, we announced that one of the ways users can generate images in Meta AI is by @-tagging the public Instagram accounts they want to reference. Our intention was to offer a useful creative tool and give users control over whether their public content could be mentioned in this way. We’ve received feedback that this feature missed the mark and is no longer available. Image | Meta, edited with Magnific In Xataka | Meta has a long history of privacy scandals.

Which cinemas meet the requirements designed by Christopher Nolan

Let’s tell you what is the best way to see The OdysseyChristopher Nolan’s new film. It is his particular adaptation of Homer’s poem, which with the director’s filmography and its spectacular cast has already become one of the film events of the year before its premiere. Nolan is known for having very particular tastes when it comes to recording his films, and ‘The Odyssey‘has not been an exception. Therefore, if you want to experience his film as he intended it, you’re going to need to seek out cinemas with particular characteristics. And this is what we are going to talk to you about. See The Odyssey as it was intended by Nolan In order to see The Odyssey as it was designed by its director, we will need a cinema with specific technologies and characteristics. Cinema should be IMAX and in 70mmsince that is how the film was shot. But now comes the bad news, because No cinema in Spain meets these two characteristics at the same time.. We have cinemas that allow you to watch movies in IMAX and others that support 70mm, but no theater in our country combines both. Best cinemas to see The Odyssey in Spain Taking into account what we just told you, you have two options: go to IMAX theaters or theaters that support 70mm with a 2.20:1 aspect ratio. These are the theaters that support each of these features. IMAX cinemas in Spain: Palafox Cinemas, in Zaragoza Kinépolis Valencia, in Paterna, Valencia Kinépolis City of the Image, in Madrid Cinesa Parquesur, in Leganés, Madrid Cinesa Heron City, in Las Rozas, Madrid Cinesa Diagonal Mar, in Barcelona Cinesa Festival Park, in Mallorca 70mm cinemas in Spain: Aragonia Cinemas, in Zaragoza Palafox Cinemas, in Zaragoza mk2 Cine Paz, in Madrid Phenomena Experience, in Barcelona If you have any of these cinemas nearby, you will be able to see The Odyssey in the best possible way in Spainalthough without getting to experience the film as it has been conceived by its director. In Xataka | There are people very angry about the inaccuracies in Nolan’s ‘The Odyssey’. But not because of the uniforms: because of the diversity

This is the sad story behind La Atalaya de Ciudad Real, the most perverted Franco sanatorium

Any Carles Porta fans in the room? If you have seen ‘Crims’ or some of his other documentary series, you already know the enormous impact that Catalan true crime has. But Ciudad Real has his own black chronicle. And it is perhaps one of the darkest and most unknown stories of our country. And, therefore, more interesting to unravel. If every city has its cursed hill, on the outskirts of Ciudad Real La Atalaya stands out, with privileged views and a legend that has been feeding itself for decades. We have it all: lady in white, psychophonies and there is something much more prosaic and sadder, which is nothing other than a building that never served its purpose and houses a tragedy that mythology ended up devouring. With tuberculosis tea, not terror. In 1943, the Ciudad Real city council bought those lands. At the request of the Patronage of Tuberculosis Patients, La Atalaya was part of a Franco plan of thirty-five anti-tuberculosis sanatoriums spread throughout Spain. The hill met the condition required by the national competition: sufficient isolation to avoid contagion, but not so much as to make access difficult. In 1954, work began and in February 1955, the first floor was ready, with capacity for three hundred beds. The problem is that medicine moved faster than brick: by the time the building could be opened, antibiotics had already drastically reduced cases of tuberculosis in Spain. Before housing a single patient, the sanatorium was born obsolete. Without job or benefit. Good location and good brick, but it was time to reform. In 1961, ownership of the building passed to the National Psychiatric Trust. The works are even slower and are not completed until 1970. A year later, in 1971, the building finally opens its doors as a regional center for people with mental disabilities. Or that’s how it was defined. And it operated like this for twenty-five years, until its final closure in 1996. From then on it was abandoned. Cobwebs, thefts, noises and a black legend that is gaining strength: rumors of mistreatment of inmates, screams of torture that can still be heard and a three-meter figure walking through the empty hallways. I would like Slender Man or the monster from ‘Backrooms‘ have so much presence. The real tragedy occurred. Easter 1987, early morning of April 20. It’s not a song. That morning, a 33-year-old police officer, Isidro Mejías, unloads his service weapon at a Citroën Visa where a young couple, María del Mar Perales Serrano and Alfredo Lozano Galán, ages 19 and 21, are. He then got into the victims’ own car and shot himself in the temple. What just happened? The Lanza newspaper titled the April 22 cover: “A police officer, alleged perpetrator of the death of two young people in La Atalaya.” The door locks were locked, suggesting the couple saw danger coming and tried to protect themselves by locking themselves inside. According to those close to the agent, married and father of two children, he led a normal life and had no known serious problems; The victims’ family did not know him at all either. Without a motive, the urban legend was later filled with crimes of passion, sects and curses. Today a plaque at the site remembers the young people who died. The lady in the white nightgown. The thing doesn’t end here. Because the ghostly woman, dressed in whitewhose figure proverbially appears on the curve leading to the old sanatorium, has been seen by motorcyclists and drivers for decades. several people interviewed for Misterios Conquenses They assure the same. It is not uncommon to find someone who has seen someone and confirms that yes, this folklore motif is repeated here more than anywhere else. The photos of silhouettes difficult to explain taken by Carlos Torrijos, the lights in the sky recorded by witnesses and collected by TVE in 2004… until Iker Jiménez echoed and turned La Atalaya into the territory of reference of the La Mancha mystery. Where does it come from? The theory says that she was a patient at the children’s psychiatric hospital who jumped out of a window, or that she was a girl kidnapped and murdered on the spot—there is no police record of this kidnapping. It even links to a previous appearance from 1939, weeks before the end of the Civil War, when several witnesses claimed to see a woman in white on successive nights who radiated her own light. Demolition and end of the curse. In 2007, the building was officially condemned; unofficially, to “end evil.” The abandonment left structures in dangerous conditions. But even that didn’t quite work: months after the demolition, the burned body of the doorman of a nearby nightclub was found near the scene. And the legend immediately incorporated it into its story. The pain comes from behind, as always. In the Manchego Studies Notebooks (#49) the prolonged inquisitorial persecution of witchcraft and witchcraft in the current province of Ciudad Real is documented, where cases of torture such as that of María de Lao are identified. Today the hill is a municipal forest park, with hiking trails, a children’s area and picnic areas. The Ciudad Real resident who goes out to play sports and the one who goes up at night looking for the lady’s curve coexist there, without much conflict. Your own video game. Local studio Sonrisilla Games—formed by designer Marta Ruiz (‘Waxipola’) and developer Samuel Sanjuan (‘SamKnight’)—is finishing ‘Stories from the Watchtower – The Witcher‘, a graphic horror adventure set on the hill. The project was born after the developers event Guadalindiein Malaga. And, apparently, it has required a lot of journalistic work from its creators: collection of oral testimonies, comparison of real events and interviews with those who experienced the history of the sanatorium up close. The game will be released in months and will mix the black chronicle of 1987, the myth of the witch of The Watchtower and the popular witchcraft documented in the area. Behind it … Read more

Huawei is building a semiconductor empire. And in the middle of the crisis, now it is going for its own DRAM factory

If Huawei has a message for the United States that tried to ostracize it with the five-year-old vetothat message is “thank you.” It was the same president of the Chinese company who commented a few days ago that, without the pressure from the westChina and Huawei could not have developed their technology at the speed they have. Because Huawei is developing an empire, and the latest reports suggest that they are going for the missing piece: DRAM memory. And they are creating a megafactory so as not to depend on anyone in a market that is far from improving. DRAM factory. It is estimated that SK Hynix, Samsung and Micron have more than 90% of the global DRAM market. With the big three focusing all their production on AI platforms, neither consumers nor companies of consumer products can access components at competitive prices, so they look for alternatives. It is said that Apple would be looking at the Chinese CXMTbut now there are those point that Huawei is creating a DRAM factory with government support. The company Swaysure, from Shenzhen, one of the technological hearts of the country, would be building with Huawei a factory with the capacity to create 12-inch wafers. The planned production would be 140,000 wafers per month and, in charge of all this, would be a former director of TSMC. chip empire. China has one goal: that at least 80% of basic technology that their companies use is supplied by national companies, and Huawei plays a fundamental role there. It is no longer about the huge campuses that they have to promote their own business, but also their presence in all the technological sectors of the country and the importance that they are gaining by becoming one of the pivots of semiconductors in China. With the help of SMIC, they have managed to develop chips with an advanced architecture in record time and, in addition, it is estimated that at least 11 factories throughout the country operate it with the help of allied companies. They create logic chips, have foundry services, and also operate in the DRAM chip segment. With the new company led by Swaysure, they would take another step to achieve greater independence from the big players in the memory and NAND chip sector. In the end, it is about creating an industrial network that allows us to achieve that 80% goal and, above all, be more independent from foreign technology. Images from Planet Labs and Financial Times in which you can see the evolution in the construction of a Huawei and SwaySure plant between 2022 and 2025. parallel reality. To achieve this, Huawei has some of the most impressive technological and R&D campuses on the planet, which has allowed them in a very short time to not only rise from the ashes, but create a parallel reality. In terms of software, HarmonyOS is on more than 1 billion devices, the Huawei Clouyd service is growing outside of China in countries in Asia, Africa and Latin America, and then there are the chips. They have the Ascend and Kunpeng optimized for both AI and edge computingrecently introduced a supercluster for advanced AI tasks and intend to change the paradigm of the evolution and development of processors with a ‘Tau Law’ under which they will begin to create their new Kirin consumer chips that we can see in devices such as mobile phones and tablets. And that they have the Chinese government support It is a guarantee. Chinese lever. Returning to Huawei’s RAM, this movement is not designed to compete against the big three in the sector, but rather to not depend on them. That is, Huawei should not want to be Samsung in such a short time, but having the capacity to make its DRAM, it could stop depending on Samsung or SK Hynix, for example. Furthermore, these types of movements are part of a more long-term strategy, one in which Huawei has gone from being a large company in China to being one of the lungs of the country’s technological developmentdriving the AI ​​platforms of other companies with its hardware and being the heart of some of the data centers in which China is going to invest 300 billion dollars over the next five years. HE esteemIn fact, Huawei will take over 60% of the Chinese AI chip market in 2026. Now, no matter how much they invest and create new foundries, they still have a hot potato: no one manufactures advanced lithography machines like ASML’s to which Chinese companies have restricted access. They are advancing through alternative techniques and reverse engineeringbut if China wants to be the first technological nation in the short term (an objective that they have marked themselves), at some point they will need those huge, next-generation “printers.” Image | ASML In Xataka | US adds Netherlands to Pax Silica alliance: ASML host nation enters anti-Chinese bloc

In Alicante they are experts making works with ancient art. Until they found a Roman sphinx embedded in a staircase

Recycling in the architecture of Antiquity (or the Middle Ages) was neither an ecological sensitivity nor an aesthetic trend. Rather, it was pure and simple economic survival. If you had good quality square stone, go ahead and build. It mattered little whether that stone had been part of a temple dedicated to Jupiter, whether it was the statue of a disgraced emperor or, as in this case, a mythological creature. It has a name: architectural cannibalism is known in the art world as spolia. And thanks (or because) of it, Spanish archeology has just solved a mystery that had been gathering dust in a warehouse for decades. In the archaeological site of El Monastil, located in the town of Elda (Alicante), researchers have “decrypted” a piece who had been camouflaged under a false identity for too long. The rain acting as an archaeologist. It all started in the year 2000, during the arduous excavation work of a late Roman wall located in El Monastil. Workers unearthed a three-step ladder that looked like a typical routine structural find. The following year, the Levantine climate worked its magic: torrential rains swept the area and caused the ashlars to collapse, exposing new features. Upon inspecting the damage, the team led by archaeologist Antonio M. Poveda discovered that one of the blocks was not conventionally quarried stone. The deliberate marks betrayed a previous history. Which? That someone, during the Visigoth or Byzantine occupation in the 5th or 6th centuries, mutilated a monumental sculpture, cutting it down with a sledgehammer to turn it into a simple step. Twenty years of confusion. Carved from local beige limestone, it was barely 31 centimeters high and 55 centimeters wide; what remains is a tiny fraction of its original volume. This sphinx was missing its head, wings and legs, with a surface so eroded by blows that its identification became a headache: an Iberian female figure or a random goddess? It wasn’t until last year, when the Archaeological Museum of Elda A thorough cleaning was undertaken when, in collaboration with Professor Ferrán Arasa i Gil, one of the greatest experts in Roman sculpture in Spain, remains were compared. And the shape matched too well with other sphinxes found in limes Germanic, from Romania and northern Italy. The verdict was unanimous: a Roman funerary sphinx from the 1st century AD The sophisticated security system for the afterlife. This creature of Egyptian origin and Greek traces is no ornament. And here is the key: it is a psychopomp, the guide in charge of collecting the soul of the deceased and transporting it. Its presence in the tomb fulfills an apotropaic function: the fierce gaze and hybrid posture, with the body of a lion and the torso of a woman, exist to scare away looters and protect the eternal sleep of those who rested beneath it. Have you seen ‘The Neverending Story’? His famous fulminating sphinxes are inspired by the same. Apparently, the owner of this piece was part of the rural elite of Ilici Augusta (current Elche). They were landowners who, in a time of great prosperity under Augustus and the Julio-Claudians, competed to display social status through monumental mausoleums. Built next to the Via Augusta. So the figure was another banner of power and prestige in full Romanization. He plunders well without looking at who. For the Visigoths, the sphinx was no longer a sacred symbol. The case of Elda, with this disdain for the artistic past in favor of pragmatism, rhymes quite well with other recycling imposed in Baetulo (Badalona), Segóbriga (Cuenca), Obulco (Jaén) or Carissa Aurelia (Cádiz). The most canonical example is found in the mosque of Córdoba: Abd al-Rahman I reused Roman and Visigoth columns and capitals, from the temple of Janus, from previous Christian villas and basilicas, to raise the forest of columns in the prayer room. In Toledo, the Christ of Light is the ancient Bab al-Mardum mosque. San Pedro de la Nave, in Zamora, was a 7th century Visigoth church dismantled and reassembled like a collage. And the same with the Basilica of Santa Eulalia, in Mérida, built on a Roman temple dedicated to Mars. Even the Almohad minaret of the Giralda in Seville was converted into a Christian bell tower by the braves. What makes special Monastil is that it is an inexhaustible “matryoshka” of civilizations. This Alicante site is a time capsule where the Bronze Age, the Punic presence, the Roman military base from the time of Pompey, the Byzantine monastery and the later Visigoth church overlap. In this immense network of strata it is easy to find history cut up and relocated, outside the contexts for which it was created. Many now lie in the warehouse of the Elda museum, treasures waiting to be reclassified and archaeological history rewritten.

It is not that mass tourism has settled in Madrid, Barcelona or Rome, it is that it has reached the Galapagos Islands

Last summer, and while Spain declared war to the sector, vacation rental reached heights that until recently would have seemed more typical of a dystopia. In fact, the platforms began to do business by pool rental for hours. Meanwhile, in places like New York, those who turned off Airbnb in 2023, had discovered that two years later only The hotels are happy. With this scenario, the Galapagos Islands have found the problem at home. The arrival of Airbnb. I told it the new york times. In the Galapagos Islands, one of the most delicate natural environments on the planet, the rise of Airbnb after the pandemic has transformed the tourism landscape. Alicia Ayalaknown as “the queen of Airbnb”, symbolizes This twist: rents apartments at affordable prices that attract backpackers and middle-class families, in contrast to the elitist tourism that dominated for decades. Figures? There is more than 1,300 accommodations of this type compared to some 300 regulated hotels, which has generated an explosion of low-budget visitors who spend less and, according to critics, contribute to environmental deterioration and the trivialization of a declared place World Heritage. Impact and tensions. Criticism focused on the inability of short-term rentals to meet the strict environmental standards that do apply to hotels, forced to pay permits, provide funds for conservation and manage waste in a territory without drinking water or sustainable energy. The proliferation of uninformed visitors multiplies harmful behaviors: garbage on beaches, harassment of protected fauna or consumption of threatened species. In fact, researchers warn that uncontrolled tourism threatens to turn the islands into a “Venice of nature”, where the immediate economy takes precedence over the preservation of unique ecosystems. Mass tourism and local economy. The archipelago went from receiving 6,000 visitors annually in the seventies to a forecast of 300,000 by 2025driven by commercial flights, social networks and the appearance of cheap excursions replacing traditional luxury cruises. What is happening is a stage that repeats in the whole planet. This overcrowding has left family hotels with empty rooms, while they compete against Airbnbs that operate with lower costs and little supervision. At the same time, the tourism sector holds at 80% of 30,000 inhabitants, so the dilemma between immediate income and sustainability becomes more acute in an isolated environment that depends on expensive imports and limited services. The legal (and political) battle. Although the Ecuadorian Constitution and the special legislation of the Galapagos recognize the rights of nature and limit hotel development, the absence of specific regulation for Airbnb creates a vacuum (the problem is not only regulatory but also effective application of an already existing prohibition) that hosts have taken advantage of. The Ministry of Tourism has declared illegal many of these accommodations and has ordered closures, but lacks effective control mechanisms, while platforms such as Airbnb claim to comply with current regulations and ask for clear rules. UNESCO has urged Ecuador to slow growth and regulate digital tourism, although attempts by hoteliers to achieve changes have remained without an official response. Threats and uncertain future. To the tensions over tourism problems add up of illegal fishing, drug trafficking and, in August 2025, the merger of the Ministry of the Environment with that of Energy and Mines, interpreted by experts as a turn towards the exploitation of resources above conservation. In this context, the dispute between regulated hotels and Airbnb hosts reflects a deeper conflict: to what extent Ecuador is willing to sacrifice ecological integrity of the Galapagos to sustain their economy. Between the pressure of tourism growth, the lack of effective regulation and political signals that prioritize extraction over preservation, the future of the archipelago as a natural sanctuary remains, more than ever, in question.

We believed that laboratories and millions were needed to build a GPU. A maker is setting one up at home

For years we have assumed that build a GPU It was a field reserved for companies with advanced factories, engineering teams and million-dollar budgets. It wasn’t an absurd idea: just look at the complexity of any modern graphics card to understand why it seemed out of reach for a person. But what he has done Matthias Balwierzknown as Bitluni, forces us to qualify that certainty. It has not replicated a GeForce nor does it intend to compete with NVIDIA, but it does is building from home a graphics machine with thousands of RISC-V microcontrollers. The first phase brings together 8,192 of those microcontrollers, each linked directly to an RGB LED. This decision makes the montage difficult to fit into the usual categories: the design brings together in the same structure the graphic processing and the surface on which the result must appear. In technical terms, it is designed to act as both a graphics card and a screen, without depending on a separate monitor. Of course, the project remains a partial prototype, still far from the scale and capabilities planned for the complete system. A GPU made pixel by pixel That architecture was not defined from the beginning. The maker began thinking about building some type of screen, but when studying the cost and difficulty of the project he ruled out resorting to components Addressable RGBwhich would have made the whole set too expensive. The alternative was more direct: solder an LED to each microcontroller and turn each chip into a visible graphics unit on its own. The decision contained part of the budget, although it multiplied the design, assembly and programming work necessary to coordinate thousands of elements. The scale becomes clearer when we look at the complete objective. A resolution of 1920×1080 would have required more than two million microcontrollers, shooting the cost and complexity far beyond what Bitluni had set itself. The maker then lowered the ambition to 320×200 pixels, a resolution associated with video games of the DOS era, but which still requires 64,000 chips. The components installed so far represent just a first stage of a machine that would multiply its size almost eightfold if it is completed. To organize such a large amount of hardware, Bitluni divided the system into 16×32 “pixel” boards, conceived as independent modules within the set. These are distributed in a circular arrangement that reminds of Cray-1the historic supercomputer of the seventies, although the reference is mainly visual. Internal coordination is also hierarchical: each group of 32 microcontrollers is under the control of a more powerful CH32V unit, in charge of organizing the operation of that section and serving as an intermediate level within the machine. The choice of the QingKe CH570 explains part of the economic logic of the project. It is a microcontroller with a 32-bit RISC-V CPU, a limited instruction set and a frequency of up to 100 MHz. It also integrates a USB controller, a 2.4 GHz transceiver and support for Bluetooth 5.0 LE. Bitluni was able to buy each unit for about $0.13, but the advantage is diluted when multiplied by the entire planned matrix: only the chips necessary to reach 320×200 pixels would exceed $8,000. The problem grows when projecting the power supply of the complete system. It speaks of an estimate of 2,161 W, equivalent to about 655 amps at 3.3Vfor the final planned configuration. The media points out that each microcontroller consumes around 10 mA, although it does not offer a breakdown that allows us to separate the expense of the chips, LEDs and auxiliary electronics. To support such a load, Bitluni has turned to a source Corsair WS3000 and own converters capable of transforming the 12 V output into the required 3.3 V. A big part of the project is also making the infrastructure that allows everything else to work. Bitluni designed the PCBs, power circuits, interface boards and breadboards, tackling a six-layer board for the first time. The complexity of the design ended up pushing him to the limits of the manufacturing service he used. In parallel, he studied an immersion cooling solution and came to the size of the acrylic container he would have needed, although he left that option on hold for economic and environmental reasons. Programming posed another problem of scale: it was not enough to manufacture the boards, the code also had to be loaded into each microcontroller. To avoid doing it by hand, Bitluni 3D printed a small tool with three contacts and attached it to the carriage. a 3D printer. A Python script sent G-code commands to move it to the exact position of each chip and complete the process in a repeatable manner. The printer thus stopped manufacturing parts to become an automated programming machine. This machine does not compete in performance, efficiency or size with a modern graphics card, nor has it yet reached the scale that Bitluni projected. Its value lies in exposing, through separate components, tasks that a commercial solution concentrates or distributes among specialized chips and circuits: calculation, control, power, coordination and visualization. By rebuilding them with low-cost microcontrollers, the maker has turned an unusual idea into a system that can be designed, tested and expanded in stages. It is not a conventional home GPU, but an engineering experiment taken to unusual limits.

The scientific explanation behind summer lipothymia

With the arrival of heat waves, streets, beaches and public transport become a perfect breeding ground for a horrible fainting or heat stroke to occur. Something that is not too isolated, since only in 2025 were high temperatures behind 3,832 deaths in Spaina number that tragically exceeds those killed in traffic accidents. An emergency. Many of these heat-related problems start with something that can go unnoticed, such as heat syncope or lipothymiawhich presents as dizziness with blurred vision and, in a matter of seconds, total disconnection. Given this, the question is obligatory: what exactly happens in our body that makes our brain decide to “turn off”? The reason. To understand why we faint, we have to go to the European Society of Cardiology, which in your official guide defines syncope as a temporary loss of consciousness due to less blood flow reaching the brain for a few moments. To understand it, when we are exposed to high temperatures, the human body activates its basic cooling mechanism, which is the dilation of its blood vessels. The goal here is to dissipate heat and cool us down, and that’s why it’s easy to see how people turn red in the heat and also feel weaker from the drop in blood pressure. And there is more. If we add to this drop in tension the stress of standing for a long time without moving or dehydration, blood tends to accumulate in the legs due to the effect of gravity. This causes the heart to not be able to pump enough blood upwards and the brain, being momentarily deprived of oxygen and nutrients, activates its emergency system, which is fainting. When falling to the ground, the horizontal position cancels the effect of gravity, allowing blood flow to return to the brain and the person to regain consciousness. Different terms. One of the most common mistakes is to put all the health problems that they cause us in the same bag and it is important to differentiate them in the following three situations: Heat syncope: It is a brief fainting due to the “sequestration” of blood in the extremities due to vasodilation and dehydration, and which does not usually leave serious consequences if there is no serious contusion and recovery is rapid. Heat exhaustion: This is a systemic condition that occurs when the body loses a lot of fluid through sweat. It is characterized by extreme weakness, nausea, headache and sweaty skin, but with the difference that there is no serious neurological alteration. Heat stroke: This is a vital medical emergency that threatens a person’s life, since the body’s thermostat collapses. In this situation, the core temperature reaches or exceeds 40°C and severe nervous system dysfunction occurs with delirium, seizures, and even coma. The risk factors. There is a large cocktail of situations that predispose us to some of these situations, such as For example, heavy meals. After a summer feast, the body redirects a large amount of blood flow to the digestive system to process the food. With the vessels already dilated by the heat, the brain is left with a very narrow margin of blood supply. This means that a little physical activity here can lead to dizziness or fainting, making light meals almost an obligation in summer. Age is also important to take into account, since the people most vulnerable to any of these medical situations are those over 65 years of age. And it is only because aging attenuates the thirst reflex and slows down the body’s vasomotor response, which causes many people to become dehydrated without ever feeling the need to ask for a glass of water. The recommendations. To avoid reaching a situation of this type, it is important to maintain good hydration throughout the day, emphasizing vulnerable people who should drink despite not being thirsty. Additionally, avoid going outside during critical hours of the day with higher temperatures or have light meals to avoid straining the body much more in the face of high temperatures.
