Water is essential for nearly every part of the human body function. It’s the transport system which moves nutrients around the body and carries out waste. Water breaks down food, keeps your body temperature balanced and keeps your skin elastic. We can live for weeks without food but only a few days without water. The following are just some of the important things water does in the body;
- Media for biochemical reactions
- Efficient cooling effect and required for perspiration
- Carries nutrients and oxygen to all cells and helps body absorption
- Moistens oxygen for breathing
- Protects and cushion vital organs
- Removes waste
- Cushions joints
Did you know;
- The human body contains between 55-75% water depending on the ratio of body fat to muscle.
- The human brain is 92% water
- Muscles are 75% water
- Bones are 22% Water
Although thirst indicates a lack of fluid, it is not a reliable measure of water need. Pay attention to the signals of water loss and minimise risk of dehydration, when more than ½ to 2 litres of fluid are lost can be life threatening.
On any ordinary day the average adult requires two litres of plain water, however on a training day you will need an additional 1 litre to ensure you are getting enough.
