Your breath, skin, and muscles may be telling you that your body is dehydrated.
Many people who are dehydrated have no idea until their bodies begin to show signs and symptoms of dehydration.
This is probably the case with tennis superstar Serena Williams, pictured above in Milan, Italy, this week.
Up to 60% of the human body is water. We lose up to 400 ml per day by just breathing.
Coughing, perspiring, or talking causes even more water loss.
Our water content can be depleted quickly if we don't replace the water loss by drinking the equivalent of at least 6-8 cups of water per day (or 48 to 64 ounces based on body weight).
Please note that the daily recommended water intake is based on a cup which measures 240 ml or 8 ounces.
For the purpose of this post, a tall drinking glass (such as the one pictured below) equals 2 cups of water or 16 ounces.
So you should drink at least 4 tall glasses of water to meet your daily recommended water intake.
SIGNS AND SYMPTOMS OF DEHYDRATION
Active people lose an average of 2500 milliliters (83 ounces) of water per day.
But even drinking 64 ounces of water per day won't replace 2500 ml (83 oz) of water loss.
The following calculation is an example of the amount of water you should drink based on your body weight.
Please note that the calculations below are based on a standard cup of water (240 ml or 8 ounces).
Based on the above calculations, if you weigh 150 pounds, multiply 150 x .5 = 75 ounces. That is equal to drinking 4 or 5 tall glasses of water a day. Or 4 regular sized bottles of Crystal Springs water per day.
The American College of Sports Medicine recommends adding 12 ounces of water to the above calculations if you plan to work out or perform strenuous physical activity (such as a prolonged sex session).
