It seems that the extreme heat accelerates biological aging in older people, suggesting that the risk of age-related diseases could be sparked.
“This is a first-scale first study to link to long-term exposure to human biological aging,” says Eun Young Choi At Southern California University. “Adults living in areas with extreme hot days in the cooler regions.”
Choi and his colleagues studied genetic data from 3600 people from 3600 people in the US. All were 56 years of age or older at the time.
The biological age of each participant calculated using three so-called epigenetic clocks, analyzing the models of chemical tags called the DNA methyl group. These models vary as they grow old and the changes have been associated with age-related diseases.
Researchers also studied air temperatures that took parties in a few kilometers in a few years later.
Participants were approximately 200 days, at least 32.2 ºC (90.2c) in six days. This amount changed according to the clock.
“Heats the exposure that increases the speed of biological aging,” he says Austin Argentieri At Harvard University, who did not participate in the study.
Previous studies on people in Taiwan and Germany have also found a style of tightening the link between extreme heat exposure and biological aging.
But epigenetic clocks do not catch the aging process or people risk the risk of diseases, says Argentie. “More work to be affected by extreme heat, extreme warmth, biological aging and age-related diseases, mortality, or lifestyle, would have been driven home from that.”
Moreover, the study did not consider entering air conditioning or spent for a long amount of time, which would change his personal exposure to warmth, says Argente. The team controlled for other factors, age, sex, race, wealth, ethnicity, smoking, alcohol consumption, obesity and physical activity.
More studies should explore the results that live in young people or in different countries, whether people may have different perspectives to keep cool, says Argentie.
The greatest risk of aging due to extreme heat can help spread measures to protect and protect the policies, says.
