Life cannot exist without water; it is a fundamental building block of our bodies, and besides that you would get thirsty.
Throughout our daily life, whether we are couch potatoes or super active, it is so essential to maintain our fluid levels, and all the fluids we are likely to ingest contain water.
Providing we drink, with the exception of alcohol, then dehydration is unlikely to occur.
But best of all just plain old drinking water is the most beneficial; it requires the minimum of digestive activity and is the most efficient in ridding the body of wastes. Not to mention it is also the cheapest.
When we need water, during a hot day or after exercise, our body triggers our mind into wanting to drink, to quence our thirst. Often we can misjudge hungry signs for thirst.
During an absorbing activity where our concentration is focused on performing well, the demands of the body for fluids can easily be ignored or not recognized. Our mind is totally on something else.
We can then run the risk of dehydration leading to muscle cramps, dizziness and other unpleasant symptoms. My son just the other day was too busy at the beach to drink although he had water there and later that night was very sick.
It is important that you drink water before exercise, preferably about 2 hours before starting and at least half to one pint depending upon the level of exertion you expecting to make.
If you are exercising in a hot environment you are likely to perspire more and will need to drink more water to replenish your fluid level. Remember exercise can be many shapes and forms, a walk with the dog, a swim at the beach not just exercise that you have done at the gym.
Only a 2% loss of body weight due to sweating can cause a drop in blood volume. This, in turn, causes the heart to beat harder in order to circulate the blood around the body.
During your exercise routine take a break every 15 minutes or so to take a mouthful or two of cool water, or if particularly strenuous, take a drink of a proprietary brand sport beverage.
Weight loss during exercising is not primarily caused by burning fat. By far the major contributor is fluid loss so top up on water after you finish your routines to keep your fluid levels balanced and avoid the risk of dehydration.
There are more effective ways to lose weight if that is your objective.
Somebody has said that if you wait until you are aware of being thirsty you are already becoming dehydrated¨.
The body more readily absorbs cool drinks during exercise than warm drinks.
A note of warning. It is unwise to drink an excess of water or a sports beverage during exercise, the danger increases as the activity becomes more strenuous so drink no more than a moderate amount, about 400 – 800 ml in each hour.
There have been examples of athletes suffering from severe salt loss in the blood as a result of drinking excessive amounts of fluid whilst exercising and some fatalities have resulted.
