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.

This water loss needs to be replaced. One litre or so needs to be as water or other non dehydrating fluids such as cold herbal teas. A little under a litre will come from food intake. The body also makes about 300ml through its own oxidative metabolic processes.

Problems that arise from not drinking enough water is as follows.

1. Pulse rate and rectal temperature increases

2. Respiration rate goes up

3. Numbness and tingling are experienced in the extremities

4. Increase in blood concentration

5. Reduced blood volume and more difficult circulation of the blood

Problems and inadequacies of the circulatory system under conditions of inadequate fluid intake leads to:

1. difficulties in breathing

2. gastric upsets

3. nausea and loss of appetite

4. if it continues, muscular and emotional problems

In a scientific study involving animals, the restriction of water gave rise to irritabliity and for some, 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

Ingestion of hot drinks may cause internal body temperature to rise, which will result in sweating in order to cool the body down. Hot drinks are sometimes used in medical practice when it is desired either to temporarily increase body temperature of induce sweating. Therefore cold or cool drinks are preferred to hot drinks to replace fluid during the day, especially if the hot drinks are the only fluid daily intake.

Sugary drinks

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.
