Hydration 101

Did you know that 60 percent of your body weight is water? That tells you how important water is to your health.

Summers are supposed to be carefree, but there is one thing we need to be extra cautious about when the temperatures rise – hydration. It’s easy to underestimate the heat and how fast our bodies become dehydrated.


To keep cool, follow these pointers:

  • Pass on the salt. Don’t salt your meals, especially when they already contain a lot of sodium. Salt “evaporates” water in the body and can lead to dehydration.
  • Fill up on fruits and vegetables. Eat food with high water content, including lettuce, watermelon, broccoli, grapefruit and cucumber.
  • Drink up. The American Dietetic Association recommends at least eight cups of water every day. You should also avoid caffeinated beverages, which can dehydrate you.

You can usually reverse mild to moderate dehydration by drinking more fluids, but severe dehydration needs immediate medical treatment. 


Staying hydrated is especially important when it comes to student athletes. Visit gwinnettsportsmed.com to learn more and to request your free Sports Injury Toolkit, a guide on how to prevent and treat many common sports injuries.
