What is the connection between excessive heat and premature aging?

The world has become a great climate Fritözü and we potatoes, at least this feeling. In this extreme heat ballet, our body suffers in different ways in the increasing blood pressure and recent data between dehydration, sunbathing, other physiological disorders, It may also be a factor that contributes to accelerating aging.

The study, published by researchers at the Leonard Davis School of Southern California, Leonard Davis Gerontology, offers data from a six -year study that proposes a strong correlation between heat exposure and increasing biological aging epigenetic markers.

Was he curious? Take your sun cream, a bottle of water and let’s give some more information About how hot waves can affect your biological age and accelerate aging.

Excessive heat wrinkles

The effect of overheating on human health is not an innovation. There are Brazilian studies This points to the relationships between the increase in mortality on hot daysEspecially among people with chronic diseases such as elderly populations and diabetes, hypertension and other circulatory diseases.

This risk increase caused by heat waves is associated with physiological effects such as dehydration in the human body, increased body temperature, increased sweat production, and blood vessel expansion.

The effects of continuous exposure to the temperature can be seen with more dry, reddish, peeling, pain or even epithelial cancers due to mutations caused by thermal stress. But how are we inside?

The study of Leonard Davis Gerontology at the University of Southern California was shown This excessive heat affects us longitudinallyIt can even damage our genes, change the ways of expressing themselves and accelerating aging.

The survey included 3,686 people over 56 years of age, participants of the US Health and Pension Study. The average age of the participants was 68.6 years old, for example, 54% consisted of women.

The group analyzed the epigenetic markers in the blood of the participants and analyzed the degree of methylation of DNA over time. Metylation analysis has been shown that genetic aging is a good “accountant ..Because the indicators indicate a larger metic in the genetic chain that interferes with the expression of genes according to age progress.

Thus, blood samples were analyzed, gathered at different intervals between 2010 and 2017: 7 days, 30 days, 60 days, 365 days and 6 years later.

In each collection, the climatic history data of each participant obtained in the National Weather Service is associated with the climate history of the residential areas. During the working period, the “heat” data included information about air moisture, so what we call “thermal feeling”, not only the air temperature, but also “thermal feeling”.

The temperatures in the environments were not taken into consideration, only the time to expose to external environments. The results make progress in the biological aging of people living in warmer regions, and there may be a difference between chronological and biological age up to 14 months.

For the research group, this aging acceleration caused by the temperature can naturally be attributed to the way the body loses the thermal regulation capacity according to the aging process, thus making the body more vulnerable against excessive heat effect.

This sensitivity can even be a predictive for larger DNA methylation that contributes to imbalance in genetic expression. Thus, the genes to be expressed can be silenced, while others can express themselves without regulation.

Another interesting truth is that the effect of overheating is a rapid and accumulated factor. Even if the signs do not appear at first, intracellular action can already give the first evidence, It will accumulate different comfort over time and cause potential damage to the future..

According to the researchers, to isolate socioeconomic factors, demographic differences, lifestyle, physical activity, alcohol consumption and smoking, epigenetic aging indicators continue to be associated with excessive heat factors.

Less despair and more water

It’s very calm right now. Although the study is a good evidence, the correlation is not a reason. Heat can really intervene in our health to be a risk factor for pathological aging, but the mechanisms triggered by this relationship have not yet been fully clarified.

Such research has a warning role about the need to develop strategies in order to think. In healthier processes for aging, including architecture and urbanism in the equation.

The “heat islands izlen, resulting from the lack of large structures, asphalt lands and green areas, contribute to the increase of thermal feelings and consequently increases our exposure to excessive heat supported by climate change.

In addition to the macro structure, we should take into account our actions of investing in health, food, exercise, leisure and professional balance.

To grow old healthy, even at this temperature, do not forget the bottle water, sunscreen and look for more cool environments. And if you want to continue to be informed with content like wine, continue to follow Tecmundo. Until later!
