Why Water
|
|
Evidence from medicine, sport, and education shows that drinking plenty of water is essential for switching on our minds. Brains dehydrate rapidly and, before we are even aware of being thirsty, concentration lapses, boredom sets in, and drowsiness and confusion take over.
|
|
Teachers have found that by encouraging students to drink water frequently, behaviour improves, conflict declines and work levels increase.
|
|
Hospitals report dramatic improvements in geriatric and psychiatric wards when patients have been encouraged to drink water frequently, even up to twenty glasses a day! Degenerative diseases reverse, memory function improves, and greater calmness and co-operation have become evident.
|
|
Sportspeople know that dehydration is a common cause of failure on the sportsfield. Good coaches insist that their athletes keep up vital supplies of water during training and competition. This enables brains and bodies to perform at the optimum level established by practice and training.
|
|
Pure water is essential as the body reacts differently to water containing added foodstuffs, flavours or juices. Caffeine (contained in tea, coffee and cola drinks) and alcohol are diuretics, which have the effect of removing water from body cells (people who drink these substances need more water to make up the deficit). Where the purity of water supplies is unreliable, distilled, bottled, or de-ionised water should be used, rather than that from the tap.
|
|
Nutritionists recommend that an average-weight adult drink 1.5 to 2 litres (six to eight glasses) of pure water each day (More water is needed at times of vigorous physical activity, or increased emotional stress, to overcome the dehydrating effects of the activity or stress).

Everyone interested in improving their brain function as well as their general health should take the majority of their liquid intake as water. Energy comes from food, but the ability to properly utilise this energy depends on keeping the body well hydrated. Efficient mental and physical function depends on water being available to all body and brain cells.

Students perform better in tests and examinations when they drink water through study sessions (a glass every hour and a half is good and many people find frequent sipping from a drink bottle with a sipper helpful). Improved performance in examination rooms has been noted when the examinees have taken a glass of water beforehand. It should be noted that pure water does not increase urine production to nearly the same degree as coffee, tea, or alcohol. Many schools and universities now allow examinees to take a water bottle into examination rooms for the same reason that long distance runners and cyclists are encouraged to take water during racing.

Drinking water frequently is a vital for the well-being of mind and body. It is cheap, simple, and miraculous! Fortunately, many businesses, schools, hospitals, and factories are now providing water purifiers and encouraging people to drink more water for improved mental and physical productivity.
