Excessive heat not only if it doesn’t feel tired, does it really make you live faster?
Scientists already increase the risk of excessive heating heat, cardiovascular disease, kidney dysfunction and even the risk of death. I often see these effects as a researcher learning how the environment affects the aging process. However, few investigations have been explored how the temperature affects the biological aging: gradual deterioration of cells and tissues that increase the risk of age-related diseases.
The new research of my team and the advances of the magazine magazine can accelerate biological aging in the molecular level, the warm-up climate shows that the warm-up climate is increasing.
Excessive temperature remaining hidden in the body
My colleagues and I have examined blood samples from more than 3,600 major adults in the United States. Measurement of DNA replacement samples – using epigenetic watches that seize metility, measured the biological age – it changes.
DNA methylation applies to chemical changes to DNA, which acts as a key to turn on and off genes. Environmental factors can affect these switches and how can be affected how genes affecting the risk of aging and disease over time. Measurement of these changes through epigenetic watches can seriously predict the risk of age-related disease.
Research in animal models, known as an harmful epigenetic memory of extreme heat, or showed that sustainable changes in DNA metilation. Research shows that a single episode of extreme heat stress can lead to long-term turns in the DNA metility between different types of mice. To test the effects of the heat stress, we climbed the epigenetic clock information to climate records to evaluate the faster biological aging of people living in faster environments.
We often saw older adults living in the areas in very hot days show that they showed faster than in the cool areas. For example, the participants living in the airs of at least 140 extreme heat per year – the heat index is classified as days exceeding 90 degrees (32.33 degrees Celcius), each year in areas of more than 10 days less than 10 days less than 10 days less than 10 days.
This connection between the biological and excessive temperature, the level of physical activity and socio-economic situation, and the accounting for a large number and community factors. This means that those who live in hot environments among people who have similar lifestyles can still live faster than biological levels.
It was more surprisingly surprising – excessive heating has a comparable effect until aging as a consumption of smoking and heavy alcohol consumption. This shows that the growth of heat can be silently in a level with old age and other great-known environmental and lifestyle stress.
Long-term social health results
Our study poured light on the connection between heat and biological aging, and many unanswered questions remain. It is important to clarify that our findings do not mean every additional year in extreme heat. Instead, our research reflects the population-level differences between groups based on local heat. In other words, we took the image of all the populations at once in a moment; Was not designed to influence individually people.
Our study also does not fully draw all the ways that people can protect from extreme heat. The factors like air conditioning, outdoors and profession exposure to exposure, all play a role in shaping personal thermal secretions and its effects. Some individuals can be stronger, while others may face greater risks due to health conditions or socio-economic barriers. This is an area where you need more research.
At the same time, this excessive heat is more than a healthy health in health – this can speed up the aging process silently with long-term results for public health.

Elderly adults are especially sensitive, because aging reduces the ability to adjust the body’s temperature effectively. Many-year-olds also receive medicines such as beta-blockers and diuretics that can disrupt heat tolerance, are becoming more difficult to cope with high temperatures. Thus, medium hot days as those who reach 80 degrees (26.67 degrees Celcius), can disrupt health risks for elderly adults.
As the US population is rapidly strengthening the waves of age and climate change in the world, it is not real to say that they simply move to the refrigerators. The development of age-appropriate solutions that allow older adult communities to remain safe and can help to have a hidden but significant impact on extreme heat, which allows you to protect the most sensitive populations.
