At the end of the day, when fatigue sets in, it is not uncommon to feel a shiver, despite the still mild temperature. Is it really fatigue that causes this? Or is it a legend? Dr. Gérald Kierzek, medical director of Doctissimo, answers us.
A yawn followed by a shiver. It’s the evening, it’s been a long day, and you’re suddenly hit by the cold even though it’s 22° at home. “It’s probably fatigue” we often say. But what is the link between fatigue and feeling cold?
A system slowed down
Dr. Gérald Kierzek, medical director of Doctissimo, simply explains the causal link, why we are cold:
“This feeling of cold is a message, our body’s way of telling us: “You are tired, you lack energy””.
Indeed, the metabolism, the functioning of the body, goes to rest in the event of fatigue and this minimum speed prioritizes vital functions. The energy is then dedicated to the brain, heart and breathing. “Heat production, on the other hand, which consumes a lot of energy, is put on hold. Your interior thermostat, regulated by the thyroid, will set the temperature to the minimum” explains our expert.
There are not thirty-six cures for feeling cold, but a series of healthy reflexes to have reminds us of Dr. Kierzek:
- The first remedy is of course rest, going to sleep, to rest your body and recharge your batteries;
- The second is to use a healthy and balanced diet, because food provides fuel for the body;
- Finally, the last remedy is to move, to practice regular physical activity. “Because sport remains to this day the best anti-fatigue remedy.” concludes our expert.
