If you care about your health, you’ve probably already heard this recommendation: Drink at least 8 8-oz glasses of water every day. Drinking something less bland than water is not considered beneficial for your health, so all these cups of coffee you’ve drunk today don’t count. Soda doesn’t count either. Sorry.
Water is obviously good for you but...
Is drinking 8 glasses of water per day really that necessary?
According to Heinz Valtin, a retired professor of physiology, the answer is no.
He says that drinking lots of water can be beneficial for people with certain health concerns, such as kidney stones or urinary tract infections. But after a research in 2002, he reports there is no evidence that healthy people need to drink lots of water every day.
So, to drink or not to drink? If you’re thirsty, go get that glass of water. Most likely, you meet your daily hydration needs by letting thirst be your guide.
