If not, you're missing some major health benefits. But it's really packed with power. We reported earlier this year on the study that determined that drinking plenty of water may help prevent bladder cancer.
Water also helps in weight loss and prevents kidney stones from forming.
Doctors at UT Southwestern Medical Center at Dallas say about 70 percent of your body is water, and you lose about two liters of water a day. Older adults should be especially conscientious about getting their daily dose of water. They still need the same amount of water, but they may be less likely to feel thirsty. UT Southwestern experts say hot weather or illness makes dehydration even more likely. The result can be weakness, delirium or even death.
