Two white men in the 60s were hundreds of miles apart, one of the states of Arizona and another in Washington state. They are the same and have the same economic and social background. They also have similar habits and in the same physical condition. But the man in Arizona is faster than a man in Washington – faster than 14 months, no one smokes or drinking. Both exercise regularly. Why is the matter that lives in the desert in the southwest is more than one year of the mobile more than his partner in the northwest Pacific?
One Studies published this week In scientific progress journals, the case of high heat is older than millions of Americans faster than their partner in a cooler weather. The impact of a chronic high temperature, researchers, it is equivalent to the effect of smoking that is a habit of cell aging.
Due to the average temperature of the world still increases due to the impact of greenhouse gas caused by the wider fossil fossil fuel of the world population is exposed to high heat, which has More than 21,000 Americans killed since 1999.– In 2023, Phoenix Arizona, which some people analyze fresh education. 31 days at the temperature higher than 110 degrees Fahrenheit– That year is The warm year in the record Around the world – the notes that are Quickly superior in 2024–
Higher heat contact The effects of short -term and long -term long -term health– People may experience heat -related illnesses such as dehydration and fainting or treating a hemorrhea, which is the most serious form of heat -related illnesses, which may lead to death. The elderly and young children are especially at risk of these effects because they have a turmer problem or maintain a stable body temperature. In the several months and the heat of the heat can be done Causing chronic symptoms that are more intense Such as kidney disease and cardiovascular disease and increasing the risk of a person Mental health problems and Dementia–
Eun Young Choi, a doctorate researcher at Leonard Davis School of Geerontology of the University of California and the main author of the study wants to find things that may push for the long -term health effects of cell contact. Especially in people who are close to Yuk 60. She is especially interested in the “non -occurrence” of heat contact, which means that she hopes to get heat affecting people who do not appear in an emergency room with heat -related or heat strips. Her hypothesis is the heat, alien, overall health, whether someone will feel that it is interesting.
To test the theory, Choi has analyzed blood samples from more than 3,600 people, older than 56 years, participating in a large national health and retirement study. Those participants conducted blood tests in 2016 or 2017, Choi and Jennifer Ilche, the author, then use the weather and climate data to assess the number of “heat days” as specified by the national weather service. After that, compare people in those groups with each other by using a set of biological tests that determine how old the cells of that person are.

“With a long-term heat for a year and six years-we see a consistent relationship between heat and age (cellular)” in different biological tests. Choi said people who live in a place at a temperature of more than 90 degrees F for half a year, compared to people who live in areas with food more than 10 days of temperature or higher than 90 degrees.
“This study is one of the first empirical assessments that occur in the long -term heat. It is directly related to the acceleration of the aging process,” Vivek Shandas, Professor of Portland University, which studied the impact of climate change to the city and not participating in it. “Increase the existing work by sighing that the short -term death may be the result of the elderly with long -term heat and periodically for heat.”
two Previously study Found that people who experience the heat age faster and education in rats Show continuously that the heat cellsBut Choi's studies are the first national representative research to draw connections. The size and diversity of her volunteers help that many factors that make this type of information cause the Choi to not find the main difference between the population data – indicating that the heat destroys the cells all over the board in the elderly.
However, what Choi does not consider is a way that people adapt to protect themselves from heat. Some of the rich Americans may be inside with air conditioning all day and night.
Previous research shows that the temperature is higher than the average does not affect the entire population equally. The heat is extremely dangerous for those who live in a city with a large number of wooden patchs and concrete. These zones in various places such as New York City and Chicago are called Urban Heat Islands and they will receive. Heat up to 7 degrees Than the surrounding rural areas The heat islands in the city tend to match the neighborhood. Non -skinned communities are imprisoned in the past by dividing the ethnic separation.Which is one reason that the general color of the color Experience the maximum heat. In the urban area rather than white people who are not average heisplain These people have little chances to be Can pay air conditioning–
“We know that some population, such as those who work outside the population that are not exempt from people living in the heat islands in the city, the population that is imprisoned and low -income residents tend to have a longer period to experience the past in the past).” Shandas “as we may draw these discoveries to suggest that some population must receive more attention and look at when they see the expectations.”
Choi hopes that future education will occur to tease these differences, particles because in 2040 1 in 5 Americans will be 65 years old. – Increased from 1 in 8 in 2000. Choi's studies also affect all age groups, not just people aged 50 years and over. “I don't think basic biology is very different,” she said. And we need to follow people from birth to the age of whether these effects can go back. “
