5 questions about hydration

From childhood to your golden years, staying hydrated is a simple thing you can do for your health.

The key is to drink water consistently, especially at times when staying hydrated becomes extra important: in hot weather, while exercising, during pregnancy, and whenever you want to be on the top of your physical game.

Why is drinking water so important?

Water is vital to the proper functioning of the human body. In fact, the adult body is about 60% water(1). So it’s essential to maintain proper hydration. Water is also indispensable in distributing nutrients through the blood circulatory system to where they are needed throughout the body.

How much water should you drink every day?

In addition to the water contained in food, adults should drink at least 1.5 liters* of water every day(2), which more or less comes out to the rule of thumb of 8 glasses**. It’s good to drink more water than that if you’re physically active or located in a hot climate, since those conditions lead to greater fluid loss through sweating.

When is the best time to drink water?

If you’re thirsty, then you are already dehydrated! The optimal approach is to drink water throughout the day before feeling thirsty, in order to prevent dehydration.

Are there times in life when you should drink more water?

Pregnant women and nursing mothers need additional fluids. It’s also important to stay hydrated when you’re sick. The thirst mechanism declines as you age, so it’s important for older people to drink regularly throughout the day, whether they feel thirsty or not.

How can you stay hydrated?

The best way to stay hydrated is to consistently drink water throughout the day before you feel thirsty. Fruits and vegetables deliver essential vitamins, and minerals, and herbal teas are a tasty way to warm up and to hydrate. Keeping a bottle of water at your side, whether you’re at home, working, or exercising, makes it easy to refresh and replenish one of your body’s most basic needs.
