Heat wave: drink yes, but not too much!
Faced with rising temperatures, hydration tips abound and recommend to as many people, especially the most vulnerable, drink plenty of water. But contrary to popular belief, older people do not need to drink heavily to avoid dehydration. This is what reminds Jean-Louis San Marco, professor of medicine at the University of Marseille.
With age, one sweats little so one loses little water. The urinary system is also slower. "So to make them drink excessively is to take the risk of drowning them," explained the doctor to our colleagues in France 3. According to him, each year, this overhydration would make unsuspected victims. The solution: adapt your consumption to your activity. If you stay in the shade, at home, you do not need to drink more than 1.5 liters a day. To cool off, we can also opt for misting, which deposits on the skin fine water droplets. Just add the air of a fan. Water evaporates, which evacuates heat and replaces perspiration.
