The human body consists of 60 percent water and we often hear how important water is for the smooth operation of our organs, tissues and cells. But it has been a good deal of discussion about how much water we need to drink. Traditionally recommendation been eight glasses of water a day (. Or about 64 oz), but recently that the recommendation has been refuted
While more than half of body composition can be water, we also lose a good deal of water every day through sweat, urine output and stool. It is important to replace the water that is lost through these natural processes.
If you do not get enough water, or replace the water that is lost, you can become dehydrated, which leads to all kinds of challenges. These include drowsiness, among others. In extreme cases, you can get very sick if you are dehydrated.
Traditionally we were told to drink eight glasses of water a day (about 8 oz. Each). This was said to replace the water we lose naturally through various bodily functions and help nourish the cells and organs with a fresh supply of water.
Other recommendations suggest that men should drink more water than women (13 cups for men and nine cups for women) and how much you drink should be related to how much you weigh and how physically active you are.
Factors affecting demand for water
There are a number of factors that affect how much water you need apart from the standard eight glasses-a-day rule. These include:
* How much and how hard you exercise
* Your Environment If you live in a particularly cold or warm place, water will your needs be different.
* Your health If you have suffered recent illness, your needs will be greater
* Your personal needs -. Are you pregnant? Breastfeeding? These may affect the need for water.
Does It All Has to be water?
In short, no. While the majority of your daily fluid should be water, you can count other beverages from water intake. These include tea, coffee and sports drinks.
You can also count high water content fruits and vegetables to your water consumption. These include fruits like grapes and watermelon and vegetables like lettuce and tomatoes.
New Thinking on water intake
A 2002 article in “American Journal of Physiology” refuted the claim that drinking eight glasses of water is the way to better health. Dr. Heniz Valtin argued that only people with a tendency to withdraw certain diseases would benefit from the traditional recommendations.
The new thinking is that people should drink water if they are thirsty, and they should drink enough water so that the urine is clear and not yellow. Drinking too much or too little water can tax the kidneys, so finding the right balance is crucial.
If you are overweight, pregnant or nursing, or in bad health (or have been sick), the water will your needs be greater.
