It’s good Known that heat causes exhaust in the body. But age?

HAS Recent study Concluded that extreme heat accelerates the aging of the human body, a world fact given the frequency of inconsisory of waves of heat due to climate change.

Research does not speak of the effects of solar radiation on the skin, but of biological aging. Unlike chronological age – the answer you give when you have asked you how old you are – your biological age reflects how your cells, tissues and organs work. Biological age can be calculated by examining physiological and molecular markers in the body as well as using various tests, for example by measuring pulmonary function, cognitive capacity or bone density.

Over time, revealed that research has revealed that exposure to extreme heat can make body systems, which appear in people’s blood pressure tests, chololesterol and blood function. In the long term, this can incron the risks of cardiovascular diseases, cancer, diabetes and dementia. Research, which was published in the journal Climate change of natureNoted that the aging effect of extreme heat was comparable to other behaviors known to be harmful to the body, such as smoking or alcohol consumption.

The researchers analyzed long -term medical data of 24,922 people in Taiwan, collected Bethaeen 2008 and 2022. Meanwhile, the island experienced around 30 waves of heat – defined by the research team as high temperature periods which last several days. Researchers first calculated the biological age of individuals, based on the results of various medical tests, such as hepatic, pulmonary and renal function. They then buy the biological age of people with the chronological age of tea, to see at what speed their biological clock was ticks linked to their real age. They then refer to this information against the likely exposure of people to heat waves.

The results have shown that the more extreme heat events have experienced, the more quickly their biological age accelerated at their chronological age. On the average, the cohort of people studied, being exposed to two years of heat waves helped eight and 12 days at the biological age of a person.

“Although the number itself may seem small, over time and in different populations, this effect can have important implications for public health,” Guo, an environmental epidemiologist at the University of Hong Kong and the main author of the study, told a study, in a statement of nature.

The study also revealed that people doing physical work and these resources in rural areas were more likely to be affected by accelerated organic aging, it was very well due to greater exposure to the effects of heat waves. However, an unexpected positive effect was also observed: the impact of heat exposure on real biological aging has decreased in the 15 years analyzed. The reason behind this is unknown, although Guo highlights the possible influence of cooling technologies such as airline, which have become more common in recent years.
