The Body’s Requirements:
Water makes up about 60% of a human body mass
If you had to drink all of the water rewuired for your body’s numerous functions you would have to drink 40,000 glasses every day. However our bodies have a fantastic ability to conserve water by efficient recycling. To maintain health, it is necessary to replenish the supply by drinking six to eight glasses of water each day.
Dehydration:
Dehydration occurs when the body’s tissues lack sufficient water to function efficiently. The effects of dehydration depend onthe amount and rate of water loss. Up here in the tropical heat expect to lose alot more water every day. Also young children, the elderly and anyone suffering acute illness such as diarrhoea or fever dehydration can occur much more rapidly.
Some of the symptoms of dehydration include thirst, weakness and tiredness, dry and inelastic skin and sunken eyes. If you experience any of these you are already dehydrating.
Water and physical activity
Althetes and people who work outdoors strenuously should ensure a plentiful water intake.
Often athletes will drink less water than they lose through sweating during sport.
Cramps - are a common ailment related to loss of water. Water needs to be replaced before, during and after activity to alow proper hydration and optimal performance.
Alcohol
Also this festive season remember that Alcohol intake causes the body to lose fluit and this loss can be significant! It is important to replenish water while drinking alcoholic beverages. Try a glass of water between drinks. Much of the effect of hangovers is caused by dehydration.
The Wonders of Water
QLD’s tropical climate can be very hard on our bodies. If you spend alot of time in the sun your body loses more water through the lungs and sweating in an effort to keep your body temperature under control. Drinking plenty of water (6-8 glasses a day) allows the body to perspire freely and keep the body temperature cool.
So please remember if you’re feeling tired, thirsty or even just lack-lustre. Have a big glass of water this summer and replace what you’re losing! And most of all, Have a safe and happy New Year!
