3. Thirst Equals Dehydration
Thirst most definitely is the mechanism through which our body tells us that it needs water. This, though, does not mean that the body has become dehydrated. Thirst results from a reduction of 2 – 4 % body water. This decrease does not pose any threats to the body as long as your kidneys are fine. Drink a glass of water and this will go away.
Dehydration, on the other hand, occurs when the decline in body water is over the 5 – 8% threshold level. At this point dehydration will be accompanied by other problems like dry mouth, tiredness and dizziness.
The American Council on Exercise’s guidelines does mention drinking about 10 oz/a glass of water every 10 – 20 minutes when you are involved in stressful activities. Such activities include exercise, and if after a ‘heavy’ work you do feel parched, simply drink up a glass of water.
