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.
Just under half of this should be in the form of drinks such as water or cold herbal teas and just under a litre from food. The remaining 300ml is created by the body from its own metabolic processes.
Problems that arise from not drinking enough water is as follows.
1. Pulse rate and rectal temperature increases
2. Increase in respiration
3. Numbness and tingling are experienced in the extremities
4. Increase in blood concentration
5. Diminution of blood volume and more difficult circulation
Problems and inadequacies of the circulatory system under conditions of inadequate fluid intake leads to:
1. difficulties in breathing
2. gastro-intestinal upsets
3. nausea and loss of appetite
4. eventually difficulty in muscular movements and emotional instability
In an animal study, where water was restricted the animals were highly irritable and in some cases bad tempered.
Thirst
It has been demonstrated that under intense physical activity a male will only drink voluntarily around 50% as much water as what is required to replace losses from urine and sweat. Only after rest and food do the cravings for the required amount of water return to replace the fluid deficit.
Hot Drinks
Drinking hot liquids can cause a rise in internal body temperature. The body will sweat to bring the temperature down. In medical practice this is sometimes used as a deliberate ploy to temporarily raise body temperature or induce the body to sweat. So cool or cold liquids are preferred to hot ones to replace fluid losses. This is especially the case if hot drinks are always the preferred choice rather than cold ones.
Sugar drinks
Water is the preferred choice of liquid for physical activities that last less than 90 minutes. For activities that would create fatigue after an hour or so, drinks that contain some carbohydrate are better for sustaining power output than water alone.
