The body can gradually improve its ability to cope with heat when it is exposed to high temperatures repeatedly over time.
This is a well-known principle in the world of sports, where athletes train in hot conditions to improve their heat tolerance.
Researchers are now examining whether saunas and hot baths can produce a similar effect, according to The Guardian.
According to the researchers, the body may begin to sweat earlier, increase blood flow to the skin, and reduce strain on the cardiovascular system when it is later exposed to heat.

Heat requires caution
The researchers emphasize that most studies have been conducted under controlled conditions.
In these studies, temperature, duration, and participants' health status are closely monitored. As a result, it is still unclear whether the same benefits can be achieved safely at home.
In addition, saunas and hot baths may pose risks for people with a fever, unstable angina, a recent heart attack, or uncontrolled low blood pressure.
These individuals should avoid heat exposure until they have been evaluated or treated by a doctor.

Sauna is not a solution during heatwaves
Regular heat exposure may help the body adapt to hot conditions over time, but this does not mean that visiting a sauna will provide protection during a heatwave.
The researchers stress that heat acclimation should take place before the hottest periods of the year and should not be used as an emergency measure on extremely hot days.
During a heatwave, it remains most important to follow public health guidance by staying well hydrated, avoiding strenuous physical activity during the hottest hours of the day, and taking extra care of vulnerable people.
