Why do we need to drink water?

We know we should drink water, but why? What happens in the body when we drink enough – and what happens when we don't? Here are the answers!

Water – the body's best friend

Water is not just a thirst quencher. It is actually one of the most important building blocks of the body. Approximately 60% of your body is made up of water. Every cell, tissue and organ needs it to function properly.

Here are some reasons why water helps the body:

You think better.

Your brain is largely made up of water. When you're dehydrated, you may have trouble concentrating, feel tired, or get headaches. Just a little dehydration can affect your mood and mental acuity.

Muscles work better

Without enough water, you can get cramps, lose energy, and have a harder time recovering. Water also helps transport nutrients to your muscles.

You maintain the right temperature

Water regulates your body temperature. When you get hot, you sweat (sweat cools you down). But if you don't replenish your fluids, your body's cooling system can stop working properly, which can be dangerous.

The body clears out waste

Water helps the kidneys filter waste products from the blood. If you drink too little, it will be harder for the body to clear out what it doesn't need, which can damage the kidneys in the long run.

Skin feels better

When you’re hydrated from the inside out, it often shows on the outside. Your skin can feel more supple and refreshed. This doesn’t mean that water is a miracle cure for wrinkles – but it does help your skin function properly.

How much water do you need?

It varies depending on age, body size, activity and weather – but a common guideline is around 1.5–2 litres per day. And no, it doesn’t have to be just water – tea, fruit and vegetables also contribute to hydration!
