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 hazard
When the outside temperature is too high, thermoregulation can be put to the test. Hypothermia and hyperthermia are the two dangers to watch out for.
Combating the heat: the right gestures
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.
Choose cool showers and baths.
Use cooling towels for relief.
Refreshing cap: the gesture that saves
G-Heat cooling caps provide immediate and lasting relief from the heat. Whether you're a sportsman, outdoor worker or simply sensitive to the heat, they'll help you face the summer with peace of mind.
