Climate change has a lethal side effect that we are only just discovering: it locks us in the house and prevents us from moving
The increasingly frequent heat waves are not harmless for the population as they cause thousands of deaths each year, with vulnerable people being the most affected by this unwanted effect. But beyond this, which is what impacts anyone the most, we are also seeing how the increase in temperature is causing let’s reduce our physical activitysince when the street becomes an oven, sedentary lifestyle skyrockets. It is studied. The first major published work In this regard, he appeared on the scene in March of this same year and analyzed data from 156 countries collected between 2000 and 2022 to identify the “thermal frontier” in which our behavior changes radically from having good physical activity to moving to a sedentary lifestyle. With all this data, the limit was placed at 27.8ºC average temperature, since, according to the study, for each additional month in which a country exceeds this average temperature, global physical inactivity increases 1.5 percentage points. And it is not a simple summer anecdote, but stopping walking, running, cycling to work or playing in the park has direct physiological consequences. In Xataka The El Niño numbers are so strong that they are beginning to make half the world nervous. We have to be able to differentiate risk from hysteria Looking to the future, The figures are chilling, since if we continue with the current trend in an inactive manner, physical inactivity caused exclusively by excess heat will cause between 470,000 and 700,000 premature deaths additional each year around the world. Added to this is the economic impact, since lower productivity and increased medical spending will mean annual losses of between 2,400 and 3,680 million dollars. Spain, Due to its geographical location and its tendency towards desertification, it has been identified as one of the European countries most affected by this phenomenon, along with critical regions such as Central America, the Caribbean, sub-Saharan Africa and Southeast Asia. Because? To understand the reasons that reach these extremes, we have to look at another study that analyzed 74 years of hourly data, combining temperature and humidity to coin the concept ‘limiting heat’. With this term we talk about those environmental conditions in which the human body cannot carry out physical activity outdoors without its core temperature reaching dangerous levels. The most alarming thing about the study is the speed at which we are losing “working” hours per year. The annual time we spend in conditions of “severe livability limitation” has doubled since the 1950s, and it is not something that affects only the elderly. It affects us all. In young adults, historically there were about 25 hours a year of heat so extreme that it prevented them from moving safely. But today that figure has shot up to 50 hours annually and continues to increase. In the case of those over 65 years of age, their tolerance threshold is lower and they have gone from suffering 600 hours of climate confinement per year to more than 900 hours per year. This means that they spend more than 10% of the year in restrictive environmental conditions. In Xataka The map that splits Europe into two when the heat arrives: where there is air conditioning and where there isn’t He pushes us to the couch. The WHO itself has been warning that climate change acts as a “threat multiplier.” Here we have the perfect example, since heat not only makes us directly sick, but also enhances other modern pandemics such as obesity, cardiovascular diseases and diabetes by promoting a sedentary lifestyle. The solution is not just to tell people “go out and do sports earlier” or “join a gym with air conditioning.” Pass byrethink citiessince if the streets do not have shade, if the parks are cement slabs without climatic shelters, and if urban planning does not adapt to the new temperatures, going for a walk will cease to be a medical recommendation and will become a risky sport for four months a year. In Xataka | The networks are filling up with maps that promise the end of the heat. One thing is what we would like and another, very different, is what we know (function() { window._JS_MODULES = window._JS_MODULES || {}; var headElement = document.getElementsByTagName(‘head’)(0); if (_JS_MODULES.instagram) { var instagramScript = document.createElement(‘script’); instagramScript.src=”https://platform.instagram.com/en_US/embeds.js”; instagramScript.async = true; instagramScript.defer = true; headElement.appendChild(instagramScript); – The news Climate change has a lethal side effect that we are only just discovering: it locks us in the house and prevents us from moving was originally published in Xataka by José A.
