Heat wave: why some support heat, others not

Although we are used to changes in season. Consequently, temperature, the experience of a heat wave can be unbearable for some people. Moreover, While others see nothing to complain about. Similarly, Two Vaudoises tell us in which camp they are located (below). For example, But why are such differences?

The vascular system

“The body has different means to manage its temperature. Nevertheless, including the skin vascular system,” explains the D^r Mathieu Saubade, sports doctor at Chun And in Unisanté, in Lausanne. However, This system is made up of blood vessels located in the dermis, under the skin. For example, When it is hot. Similarly, the latter expand, which increases the heat wave: why some support skin blood flow and promotes the dissipation of heat to the outside. Similarly, Conversely, in winter, the vessels contract, preventing it from escaping. Meanwhile, This vascularization capacity is different from one person to another. Moreover, ”

In other words, those who quickly become red when it is hot have a reactive skin vascular system. Moreover, Unlike people who keep white skin, even in full sun.

The sweat glands

“Another thermoregulation system is perspiration,” continues the specialist. Therefore, Everyone has more. Similarly, less the same amount of sweat glands, but they do not work in the same way from one individual to another. Meanwhile, Some people sweat a lot. This makes their temperature drop by evaporation of sweat, while others less. They therefore manage to evacuate heat and support it badly. ”

The brain and the mind

Another essential component of thermoregulation, which varies enormously from one individual to another, is the feeling. Mathieu Saubade specifies: “The hypothalamus, located in the brain, is the main thermostat of the organism. Each person has a different neuroendocrin tolerance threshold. Genetics partly explains it, but also our hot or cold management experiences. A person who has been traumatized a very cold day will have more difficulty managing the frosts than someone. who has not experienced this type of experience. The mind is very powerful. and those who are used to submitting to extreme efforts or temperatures better support the heat wave or harsh winters. ”

Resist the heat wave, it trains!

With more and more hot summers, people who do not support heat should not resolve to suffer. heat wave: why some support “It is possible to train the body to better manage temperatures. Athletes are generally more effective in their thermoregulation because they are used to sweating. Make saunas regularly. as well as cold baths leads to the cardiovascular system and the sweat glands to work well, ”explains Mathieu Saubade. To train the mind. nothing like to surround themselves with people of trust already used to these practices, and go gradually makes the experience fun and easier.
