Why We Should Drink Eight Glasses Of Water Each Day

By: Maria Esposito Normally, approximately 2.5 litres of water is required daily for a fairly sedentary adult in a normal environment to replace the total loss of water that occurs though urine, faeces, skin and lungs.

To replace the water loss about 1 to 1.2 litres needs to be in drinks, (mainly water or cold herbal teas), 0.9 ml is taken though food and 0.3ml will be made by the body (oxidative metabolism).

What happens if you don't drink enough water?

1. The pulse rate goes up and there is an increase in the rectal temperature

2. Respiration rate goes up

3. Experience numbness and tingling in the fingers and toes

4. Increase in concentration of the blood

5. Diminution of blood volume and more difficult circulation

The difficulty and inadequacy of the circulation of blood under these conditions leads to:

1. breathing problems

2. gastro-intestinal upsets

3. feelings of sickness and not wanting to eat

4. if it carries on for an extended period it will cause problems with muscle movement and unstable emotions

In an animal trial, restricted water intake led to irritablitiy and in some cases, bad temper.

Thirst

Under a great deal of physical activity it has been demonstrated that a man will only choose to drink half of the water intake needed to replace losses from sweat and urine. It takes a period of rest and a meal for the cravings for water to return to replace losses.

Hot Drinks

After drinking hot liquids, the internal temperature of the body rises, resulting in sweating. This cools the body down. This is sometimes used in the practice of medicine when an increase in body temperature is required for a short time, or whether sweating is required. So it is preferable to choose cool or cold drinks rather than hot ones to replace fluid losses, particularly if hot drinks are the only types of drinks that are normally chosen.

Drinks containing sugar

During periods of physical activity that last under an hour and a half, water is the preferred choice. However drinks that contain a small amount of carbohydrate can sustain power better than water alone during activities that would create fatigue in an hour or longer.
