Body thermoregulation

Man is a homeotherm: a living being whose constant average temperature is independent of the surrounding environment...

Resisting cold, adapting to heat, maintaining a constant internal temperature of around 37°C, whatever your metabolic rate or the temperature of the surrounding environment: this is the principle of thermoregulation.

When a person is exposed to the cold for too long, their body may become unable to maintain an adequate temperature to function properly. If the oral temperature falls below 35°C, the person is hypothermic.

Hyperthermia, on the other hand, is a rise in body temperature caused by an accumulation of heat. This phenomenon occurs particularly in the event of sunstroke or heatwave.

Too much cold or too much heat is a source of discomfort, and can even lead to injuries such as frostbite...

Why are hands and feet more exposed to the cold?

Feet and hands are the first limbs affected by the sensation of cold, mainly due to reduced blood circulation at these levels. In addition to a sensation of local cold, this creates a loss of motricity and overall body fatigue.

The brain, alerted by this unpleasant sensation, triggers a surge of energy to warm the hands and feet, without success for the most sensitive.

For example, people with Raynaud's disease (3-12% of men and 6-20% of women are affected). This is followed by a feeling of weakness accompanied by shivering.

The benefits of heated garments

To (re)act when the body can no longer do so, and to prevent the risks associated with the cold, G-Heat has developed a range of heated garments to provide continuous warmth, well-being and comfort during your activities.

High-performance garments, suitable for outdoor activities in cold weather, which can even be used without batteries when temperatures remain cool but bearable, but also as comfort aids for all those suffering from cold.
