Why We Need to Drink Water
Our bodies are estimated to be about 60 to 70% water. Blood is mostly water, and our muscles, lungs, and brain all contain a lot of water. We need to drink water because water is needed to
- Regulate body temperature
- Provide the means for nutrients to travel to all our organs, which is necessary for body function.
- Water also transports oxygen to our cells,
- Remove waste (through urine and bowel motions.)
- Protect our joints and organs.
- It is needed for Digestion, Absorption, Circulation and Excretion
- Helps the body metabolise stored fats (helps in weight loss and reducing cellulite)
- Improves the look of our hair, skin, eyes, and muscle tone.
- Balances the PH in our body (It is important, as a lot of modern diseases can be helped by having the right PH and reducing acidity.)
Almost all of the body's living cells need and depend on water to perform their functions. Water carries nutritive elements to the cells and carries away waste materials and salts to the kidneys.
Water serves as an important constituent of lubricants, helping to cushion the joints and internal organs, keeping body tissues such as the eyes, lungs and air passages moist, and surrounding and protecting the foetus during pregnancy.
Water is needed in each step of the process of converting food into energy and tissue. Digestive secretions are mostly water acting as a solvent for nutrients; in effect, water softens, dilutes and liquefies food in order to facilitate digestion. It also helps move food along the alimentary canal. Differences in the fluid concentration on either side of the intestinal wall facilitate the absorption process.
Water does not contain any calories. The body absorbs water through the stomach and gut. Water leaves the body through urine, sweat, and stool and at times, vomiting and diarrhoea.
How Much Water Should We Drink
The General rule is 8-10 glasses a day, which works out to be 2.5 - 3 Litres daily. That is the average sort of day, but there are exceptions to the rule where you might need to increase this amount of water during that day.
It is important to balance the amount of water going in to the body with the amount of water being lost by the body. This is especially important for persons who are:
- Very young
- Ill with fever, vomiting or diarrhoea
- Taking medications that cause the body to lose water
- Living in hot, humid, dry or high altitude climates
- People who sweat a lot due to work
- People working in Air Conditioning (as it tends to dehydrate you)
- Travelling on a long airplane trip
