It may make you live with extreme heat faster

Exposure to severe heat may lead to faster aging, which is new Ticket I was published today in the magazine Science progress Suggest. The elderly who live in more hot areas in the United States showed aging faster at the molecular level than people living in cooler areas.

The study was considered in the standards of the biological or linguistic age of the person, which is based on how a person’s body works at molecular and cellular levels and does not necessarily coincide with the age of a person based on childbirth. Long -term exposure to heat has been associated with an increase in a person’s biological age for up to 2.48 years. The effect on the body is similar to the effects of smoking, according to the authors of the study.

“We are somewhat amazed (in) how large this effect,” says Eun Young Choi, the main author of The Study, and a post -PhD partner at the University of Southern California. “Severe heat effects may not appear immediately as a diagnostic healthy condition, but it may have silent losses at the cellular and molecular level that can develop years later into disability and disease.”

The research included blood -collected samples of 3,686 adults between the ages of 56 years or older who live throughout the United States. The authors of the study compared those samples with the heat index data, a scale of temperature and humidity, between 2010 and 2016. They found a relationship between greater exposure to severe heat and the greatest jump in the Lagini era. A person who lives in a place where the heat index is 90 degrees Fahrenheit or higher for a period of half a year.

“The interesting thing here is that many monitoring data focuses on the acute effects of heat exposure-and this paper confirms that there are chronic effects on the Lagini era, which are important predictions of environmental health.” freedom.

Nuri Sarma and Choi says it is important to keep in mind that the study does not take into account whether a person has access to air conditioning or other ways to stay cold. There is a room for more research on factors that may make the individual more flexible or more vulnerable to heat.

“Our discovery does not necessarily mean that every person who lives in Phoenix, Arizona, for example, has an old biological age. This is really a medium effect,” says Choi. “Two people in the same neighborhood can have completely different levels of personal exposure depending on whether they have air conditioning.”

This also shows that there are steps that can be taken to maintain people’s safety in the world of warming. Aside from stopping climate change, this can seem like cultivating more trees and drawing white houses Preventing urban areas from hunting the same amount of heatAnd open more public places where people can access air conditioning. Finding solutions becomes easier when people are more aware of the potential dangers.
