After the story about drinking and the loss of water, people rushed to count the losses with sweat, breath and intestinal contents.
Everyone saw how we exhale a lot of steam in the cold. The thought immediately arises that this is how water leaves the body. It doesn't really go away. This is such a miracle.
Carbon dioxide
The point is that we exhale the same amount of carbon dioxide and water.
If we have everything in order with the level of carbon dioxide in the blood, then we cannot lose water with breathing.
The fact is that carbon dioxide is produced in our country by burning carbohydrates and fatty acids. The result of this combustion will be water and carbon dioxide in equal parts.
And we exhale water and carbon dioxide in equal parts.
It turns out that no matter how we breathe steam, we cannot lose water in this way. Because the very fact of exhaling carbon dioxide indicates that we have received the same portion of water somewhere inside us. Magic.
I advise you to read my articles on salt and water:
