Although many pensioners go into warmer climate for retirement, a new USC Leonarda studio shows that extreme heat can accelerate the aging process Swws reported in the elderly.
It seems that people living in areas with several days of hot weather faster old at a molecular level than the residents of the cooler regions, according to the study, published in the Science Advances journal.
The effect has been shown to accelerate “biological aging,” the researchers revealed, causing new concerns to influence long -term health.

Although the chronological age is based on the date of birth, the biological age is measured that the good body functions at the molecular level, according to the National Institute of Agreement.
Having biological age higher than your chronological age is associated with a higher risk of illness and death.
Also, extreme heat (categorized as 90 degrees Fahrenheit and more) is long connected to health problemsIncluding an increased risk of death, SWWS report states.

In the study, Senior author Jennifer Ailshire (professor of gerontology and sociology at USC Leonard Davis School) and co -author Eunyoung Choi (NAC Leonard Davis postdoctoral scholarship player) examined the biological time changed over the six -year periods in thousands of American and older years.
Blood samples taken at different points are analyzed to certain changes – called “epigentic changes” – in the way individual genes are included “on” or excluded, “the public statement said.

The research team used mathematical tools called “Epigenetic Watches” for analyzing these patterns and biological assessment, as SWWS reported.
They then compared the changes of older participants in biological age with the history of heat at their locations and the number of thermal days, which the National Meteorological Service reported from 2010 to 2016.
Participants living in areas with more than half of the year above 90 degrees Fahrenheit have experienced up to 14 months of additional biological aging compared to their colleagues about cold weather. (East)
Analysis has discovered a “significant connection” between an area with multiple days extreme heat And individuals who have a greater increase in biological age, even after adjusting other factors.
“Participants living in areas where thermal days are defined as 90 degrees Fahrenheit or more – they occur half a year, such as Phoenix, Arizona, have experienced up to 14 months of additional biological aging compared to those living in areas of less than 10 thermal days,” Choi said in a statement.

The study used the heat index, not just the air temperature, to take into account the relative humidity, Ailshire noted in the edition.
“Older adults are not sweating in the same way. We start to lose the ability to have a skin cooling effect that comes from that evaporation of sweat.”
“It’s actually a combination of heat and moisture,” Ailshire said.
“Especially for older adults because [they] Do not sweat the same way. We start to lose the ability to have skin cooling effect It comes from that evaporation of sweat. “

Dr. Chris Scuderi, a family doctor based in Jacksonville, Florida, spoke with Fox News Digital about what he noticed about the heat and aging in his field.
“I noticed a significant increase in hospitalization and incidents associated with heat among older adultsespecially during a record temperature last summer in the northeast [Florida]”said Scuderi, who was not involved in the studio.

Certain medicinesLike antidepressants and heart medicines such as beta blocker, it can further impair the body’s ability to regulate the temperature, which increases the likelihood of a disease associated with heat, the doctor states.
Some chronic health conditions can also change the normal body reaction to heat, conditions of centers for the control and prevention of the disease (CDC).

Scuderi offered some tips to help people beat warmth.
They include scheduling outdoor activities during cooler parts of the day, maintaining appropriate hydration and check all medicines with Family doctor identify any potential problems.

Another CDC advice is to drink water before you feel thirst.

“If your doctor limits amount of fluid You drink or drink you on water pills, ask them how much you should drink during hot weather, “recommends the website.
The next steps for the research team will be a determination that other factors could make someone more vulnerable to biological aging associated with warmth and how it can be associated with health.

In the meantime, Ailshire noted that the findings could encourage creators of politics, architects and others to retain heat and features of adapted age while updating urban infrastructure, such as building bus stops with shaded surfaces, planting multiple trees and increasing urban green areas.
