How much water do you need to drink?
If you weigh 160 pounds, you need to drink at least 80 ounces of water or other fluids per day.
If you exercise, you should drink another 8 ounce glass of water for every 20 minutes you are active.
Water protects your Overall Health
Clinical studies show that drinking 8 glasses of water a day can decrease the risk of colon cancer and bladder cancer, and may reduce the risk of breast cancer. Preliminary research suggests drinking 8 to 10 glasses of water a day can ease back and joint pain for up to 80 percent of sufferers.
Water Aids in Digestion
Healthy digestion requires adequate fluid intake. The colon is your body's fluid regulator. If you're not drinking enough, your colon steals water from the waste material and gives it to the body, causing the stools to be water deprived or hard. These hard, dry stools are difficult to pass, because they stick to the dry wall of the colon.
By drinking plenty of water each day, you help your body stay hydrated enough, so that it doesn't need to extract much water at all from the solid waste materials that are moving through the colon.Since the waste material keeps its water, it stays soft and pliable so that it's able to move through the colon at a much easier and faster rate.
One of the important jobs of water is to help your kidneys remove wastes like uric acid, urea, and lactic acid. If you do not have enough water to dissolve the wastes then they cannot be removed effectively and you run the risk of kidney damage.
