How much water do you need to drink?

For most people, not 8 cups. In 2002, Heinz Valtin, a nephrologist at Dartmouth Medical School, USA, spent nearly a year searching for evidence for the claim "you need to drink eight glasses of water a day" and ultimately failed. "We found no scientific evidence for this advice," Valtin said.

So how much do we need to drink? "It depends on your body size and how active you are," says Kristin Reimers, director of the Center for Human Nutrition in Omaha, USA. You can tell if you're drinking enough by looking at the color of your urine. Light yellow indicates that you are sufficiently hydrated. If not, listen to your thirst. "Our bodies have an amazing ability to tell us when we need water," says Valtin. "You don't have to force yourself to drink water."

What other drinks are taken into account?

Have. Juice, milk, soda and other liquids all help to hydrate the body. Even caffeinated beverages - long accused of dehydrating the body - are taken into account. In a study conducted by the Center for Human Nutrition in 2000, participants were given plain water alone or in combination with other caffeinated beverages. The results showed that no matter what they drank, they consumed the same amount of water. Food is also another good source of fluids. Fruits and vegetables can make up 95% of the water. Nutritionists have estimated we can get 2 to 4 cups of water a day from food.

Is it possible to drink a lot of water?

You can, but not sure. "Our body's water balance system is so sensitive and precise that a case of water poisoning is unlikely," says Valtin.

Is tap water safe?

Usually it's safe. But its quality depends on the source of the water, how it is treated, the distribution system as well as the pipes it flows through, so you need to know for sure what is coming out of your faucet.

Should I bring water to test?

Even if your water supplier assures you, you still want to test for lead and arsenic in your water, as these can be harmful to your family's health. Sometimes lead contamination comes from pipes in the homes themselves, so what people claim is not necessarily accurate.

Should I use a filter?

If you know that your water is contaminated with lead, arsenic or other harmful substances, it is a good idea to purchase a filter. Also depends on what you want to filter to buy a filter accordingly.

Is bottled water better?

Not necessarily. Bottled water is not necessarily better, cleaner, or safer than tap water and has its own problems. In a 2000 test in the United States, it was found that one-third of water bottles contained toxic levels above the safe limit.

Does water temperature matter?

Whether you drink cold or warm water, it makes no difference to your body. But do not use hot water directly from the faucet, it will carry more lead than cold water. Allow the water to cool for at least 60 seconds.

Does the water go bad?

Have. More precisely, the things in it will be damaged. Water is an excellent environment for bacteria. So think again before drinking from an unfinished water bottle from the other day. A Canadian study found high levels of bacteria in half-baked water bottles that weren't pasteurized. Please wash the bottle with warm soapy water. Place the water bottle in a dark and cool place because light and heat will damage the bottle.
