How much water to drink per day
People will often scoff at the idea of drinking x amount of water per day, but
the truth is most of what we drink in the 'modern world' actually serves
to dehydrate you ! Here is an interesting article with a good way to determine
what you should actually drink.
Calculating Your Own Daily Water Requirements
By Dr. Thomas Stearns Lee
The human body is composed of 25% solids and 75% water. Brain tissue is said to consist of 85% water.
It has become a practice to regard a "dry mouth" as a signal of body water needs, which is further assumed to be well-regulated if the sensation of "dry mouth" is not present. A dry mouth is the last outward sign of extreme dehydration, however. Damage occurs to the body at a persistent lower level of hydration. Because of a gradually failing thirst sensation, the body becomes chronically and increasingly dehydrated.
Signals of dehydration can be any of the following symptoms:
Heartburn, stomach ache
Non-infectious recurring or chronic pain
Low back pain
Mental irritation and depression
Water retention ( ironic but true! )
Further problems often develop when the sensation of thirst urges an intake of water, and instead, soda pop, coffee, or alcohol-containing beverages are taken to quench the thirst. While these beverages contain water, they are actually dehydrating fluids. Not only do they eliminate the water contained in them, but they also cause you to lose further amounts of water from your body's reserves!
Daily Water Requirements: Drink 50-75% of your body weight in ounces. Sedentary people: 50%; Active people: 75%
Pounds of body weight 150 lbs
Water requirement from above (75% of body weight for an active person) 112.5 Oz
Add for dryness of climate
Add for strenous exercise
Total per day 144.5 oz.
Divide by the number of hours you're awake to find your hourly water requirement: 144.5 ÷ 16 = 9 oz.
Therefore, a 150-pound active person who works out should drink 9 oz. of water for each hour awake.
This is only an estimate. "Actual milage may vary."
