I/2 oz per pound of body weight?? Holy cow, I might as well just put the garden hose in my mouth and turn the spigot on.Britesea said:Actually, sometimes high blood pressure can be a sign of dehydration. Very few people drink as much water as they really should (1/2 oz per pound of body weight). Thirst is NOT a reliable indicator of dehydration. If you aren't getting enough water, the blood literally gets thicker, which means the heart has to work harder to pump it.
