To work well, our body needs water. We all know that we should drink at least 2 litres of water a day but here are some more reasons why our body needs water.

1. Lubricates the joints

One of the reasons for joint pain is the lack of drink water. Cartilage, found in joints and the disks of the spine, contains around 80 per cent water. Long-term dehydration can reduce the joints’ shock-absorbing ability, leading to joint pain.

2. Produces saliva and mucus

Saliva helps us digest our food and keeps the mouth, nose, and eyes moist. This prevents friction and damage. Drinking water also keeps the mouth clean. Try to have plain water instead of sweetened beverages, as it can also help reduce tooth decay.

3. Delivers oxygen throughout the body

Blood is more than 90 per cent water, and blood carries oxygen to different parts of the body. It is essential to drink water to help the oxygen flow throughout our body.

4. Boosts skin health and beauty

When you are dehydrated, your skin becomes more vulnerable to skin disorders and premature wrinkling. Drink water to maintain healthy, youthful and glowing skin.

5. Cushions the brain, spinal cord, and other sensitive tissues

Dehydration can affect brain structure and function. It is also involved in the production of hormones and neurotransmitters. Prolonged dehydration can lead to problems with thinking and reasoning.

6. Regulates body temperature

Staying hydrated is important for keeping your body temperature under control. Your body loses water through sweat during physical exercise and in hot climates.

Your sweat keeps your body cool, but your body temperature will rise if you don’t supply the water you lose. That’s because your body loses electrolytes and plasma when it’s dehydrated.

If you’re sweating more than usual, make sure you drink plenty of water to avoid dehydration.

Also, having a lot of water in the body may help to reduce physical tension if heat stress happens during sports or some form of exercise.
