A study published in Science Advances concludes that people from warmer places aging faster than those of cooler places. “The impact is similar to the effect of smoking and drinking alcohol,” says the main author.
People who live in warmer places grow faster than those who get used to cooler sites. Exposure to extreme temperatures aging as much as smoking or drinking water, suggests a .
The researchers analyzed the exhibition of people over 56 years at different temperatures in the United States. Blood samples of more than 3,600 people.
The study concludes that people exposed to more extreme temperatures aged faster than those who live in cooler places, even after taking into account the financial situation, habits of life and education.
People from warmer regions two United Stateshow where the heat index exceeds 32 degrees Celsius for more than half the year, it seemed 14 months older biologicallythan people from cooler places such as Seattle, which only 10 days a year exceed this value.
“The impact is similar to the effect of smoking and drinking alcohol,” says Eunyoung Choi, lead author of the study and gerontology specialist at the University of Southern California.
Prolonged exposure to extreme heat can modify or behavior two genes People: accelerates molecular aging and affects health, the study says.
High temperatures cause short -term problems, as can be seen in requests for help from health authorities in heat vacancies, but the investigation relates to extreme temperatures to aging and early onset of health problemssuch as dementia, diabetes and cardiovascular disease.
O number of extreme heat days in the United States may increaser in much of the country until the mid -century. At the same time, Americans are aging, which means that their organisms are no longer so heat resistant.
Researchers consider the results important to help authorities to prevent future damage.
