Practicing sport but also a heat wave rhymes with sweat, sweating being a thermal self-regulation mechanism that must be respected.
First thing you need to understand: perspiration is a thermal self-regulation system. In particular, it allows the body to cool down when a spicy food, external heat or physical activity tend to warm it. In the context of an exercise, it can thus be the witness of the response of our organism to the setting in motion of our body. But beware, it manifests itself more or less abundantly in everyone, without being an indicator of the effectiveness of the exercise in question.
Sweat, made up largely of water, does not reflect the expenditure of calories. Sweating only leads to occasional weight loss, offset by the hydration and rehydration that this harmful heat source requires for the proper functioning of the body.
What to drink? Quality first: the liquid of which we are made up of more than 90% is water. So drinking water is definitely the best advice you can give. Certainly not soda: for example there are more than 10 sugar cubes per glass for a cola.
And even less alcohol because the more you drink an alcoholic beverage, the more you become dehydrated. How much to drink? It depends. Heat, physical activity. But there is one unstoppable witness… the amount that comes out. Less than 1 liter of urine per day is a sign that you haven’t drunk enough.
A thermal self-regulation system, not calorie expenditure
Some think that sweating is a good method of weight loss or sweating can be used occasionally to reach the required weight. To fulfill a long-term objective, this is of no use. If you were planning to refine your figure with hours of sauna and no physical activity: you can forget!
