Heatwave: how does the human body combat the heat?
37°C: that's the internal temperature our bodies need to maintain, summer and winter alike, in order to function properly. But how do we adapt to heatwaves?Focus on thermoregulation and solutions for keeping cool.
THE HUMAN BODY, A VERITABLE THERMOSTAT
Man is a homeotherm, capable of maintaining a constant internal temperature, whatever the external heat. This fascinating process, known as thermoregulation, relies on several mechanisms:
- Perspiration: as sweat evaporates, it cools the skin.
- Vasodilation: blood vessels dilate, bringing more blood to the skin's surface to dissipate heat.
- Ventilation: we breathe faster to evacuate heat through exhaled air.
WHEN HEAT BECOMES A DANGER
When the outside temperature is too high, thermoregulation can be put to the test.Hypothermiaandhyperthermiaare the two dangers to watch out for.
How to beat the heat : the right thing to do
To help your body stay cool, adopt the right reflexes:
- Hydrate regularly, even if you're not thirsty.
- Wear light, loose-fitting cotton or linen clothing.
- Stay in the shade and avoid strenuous exercise in the heat.
- Prefer cool showers and baths.
- Use cooling towels for relief.
Cooling jacket: an effective solution
When the heat is on, cooling vests are an invaluable ally. Effective and easy to use, they provide immediate and lasting relief. Whether you're a sportsman, an outdoor worker or simply sensitive to the heat, cooling vests will help you get through the summer in complete serenity.
Don't wait until you're in a dangerous situation to take action! Take the initiative and adopt the right gestures to protect your body from the heat.
