Water: Without it you will die in a week
It is overlooked by many people in terms of its importance, and people should understand why water is so important for them. It helps the body to regulate temperature, disperse heat, get rid of waste and toxins, deliver nutrients to the body, and it is the medium by which many chemical reactions take place in the body.
Water is second in importance only to oxygen
Between forty five to sixty percent of a person’s body weight is made up of water. The difference is because muscle contains eighty percent water, and fat contains only twenty percent water. Some people are fatter than others, and this is why some people carry more water than others do. It is for this reason that the average woman carries less water than a man does.
Maintaining the right balance of water in the body is simple enough, replace the water that you lose every day, and you will be fine. People lose water at varying rates due to different environmental factors and activity levels. If you live in a hot and humid area, you will lose more water than someone living in the Northern hemisphere. Likewise, if you are particularly active, you will lose water faster than your couch potato neighbor.
Typically, you will disperse of water each day in the following way:
- 200 ml per day via the gastrointestinal tract.
- 300 ml per day via the lungs.
- 500 ml per day is evaporated through perspiration.
- 1500 ml per day is lost via urinating.
Dehydration occurs due to increased blood osmotic pressure, decreased blood volume and a reduced supply of saliva to the body. All of these reactions in the body stimulate your sense of thirst, which is located in the hypothalamus in the brain. Sadly, this process is rather slow, and you can sometimes only realize that you are thirsty when it is too late.
While you can survive without food for thirty days and can only survive a few days without water, you are surely going to feel hungry long before you feel thirsty.
Normal functioning adults need six to eight glasses of water each day. If you exercise, then you need to drink more than this. Before exercising, drink a minimum of half a liter of water and make sure that you have access to water during your training session. If you want to remain hydrated, you need electrolytes and water.
Many electrolyte based drinks contain glucose, and this can be a challenge if you are watching your weight. Even though you are exercising, it is possible that you will pick up unwanted pounds due to the extra sugar. One option is to take Rehydrate.
This is an electrolyte replacement solution that you add to water
Rehydrate contains magnesium, sodium and potassium all in the right balance to keep you fit and healthy. The magnesium contained in the solution will help to prevent you from experiencing cramps due to loss of magnesium. The best part of rehydrate is that it contains no artificial ingredients or sugar.
The take away from this post is that you should drink water long before you begin to feel thirsty. If you exercise regularly, then you need even more water as you will perspire much more than someone who does not exercise. If your exercise sessions are longer than one hour, you will need to drink an electrolyte replacement drink in addition to drinking water.
