Why We All Need Water

What do you think is the best drink in the world?

Well it might not taste of anything, but plain old water really is the best drink in the whole world!

Do you know why water is so amazing?

Over half of your body is water.

Every single cell in your body is mostly made of water and needs to be surrounded by water all the time to work properly. This is because the water in your body performs a huge number of important functions that keep you healthy.

Water transport things around your body.

Water is the main ingredient of your body fluids such as digestive juices, blood, lymph and urine (wee). Your blood acts as a transport system. It carries good things like oxygen and food to all the cells in your body and removes the things that your cells don't want such as carbon dioxide.

Lymph is a liquid that carries germs and toxins away from your body. Urine allows your body to flush out waste and excess water completely.

It keeps you cool

Your body needs to keep itself at a temperature of 37°C at all times. If the weather is very hot or if you have been exercising your body uses water to cool you down by sweating. When you exercise your muscles create a lot of heat and sweating helps your body remove this heat.

Our bodies are losing water all the time – when we go to the toilet, when we sweat and even when we breathe - so we need to replace it to keep our bodies in balance.

How much water do we need to drink?

The amount of water you need to drink depends on what you are doing and how hot it is. You will need to drink more water than usual when you play sports or are running about so it's a good idea to keep a bottle of water nearby so you can top up as you go.

You also need to drink more when in very hot weather. If you don’t drink enough water you could end up with dehydration which will make you feel sick and. If you get very dehydrated it can be very dangerous indeed. Your brain will tell you when you need to drink by making you feel thirsty. You can also tell when you are dehydrated by the colour of your urine. When your body is short of water, you will go to the toilet less often, and your urine will be dark yellow in colour. If you are drinking enough your urine will be pale and there will be more of it!

Do we have to drink water?

Plain water is by far the best drink you can give your body, but all drinks such as fruit juices and milk also contain water. You just have to be careful about how much fruit juices or pop you drink as they often contain a lot of sugar which isn’t good for your teeth.

Did you know that certain foods also contain water? Fruit and vegetables in particular contain a lot of water in their juice so tucking in to an apple or a peach is a good way to help top up your water levels.
