Risk of overhydration

Like a lot of advice on social media, this one isn’t based on any scientific research, Vincent Valinduk, a general practitioner and author of the book, is quick to point out. 70 gestures of health (1). “There is no interest in drinking so much water a day, it is even dangerous for health,” continues the doctor, who first of all urges you not to treat yourself on social networks.

Consuming too much water can actually be toxic to the body. “Our body, being 65 percent water, we must maintain this natural balance,” says the doctor. In the case of an imbalance, one can suffer from water intoxication, also called “hyperhydration”.

The symptoms are serious. Overhydration “decreases the concentration of salt and sodium in the blood and causes nausea, vomiting or even headaches,” notes Vincent Valinduk. In some extreme cases, neurological disorders can develop, even brain swellings, which pose a threat to life.”

The keys to good hydration

No need to resort to a maxi-flask. To stay properly hydrated, your doctor reminds you to drink 1.5 to 2 liters of water each day, depending on your age, environment, or health. During sports practice and high heat, “we increase our intake to about 2.5 liters because sweat dehydrates.”

The ideal is to listen to yourself and hydrate yourself regularly according to your needs, while keeping in mind that “the feeling of thirst disappears with age”. In addition to the recommended water intake, the doctor reminds us that it is important to have a balanced diet, particularly with fruits and vegetables that can replenish hydration.
