When exercising or playing an active sport, the body stays cooled off by sweating. However, if people lose too many fluids or don't drink enough, they could become dehydrated, which could lead to muscle spasms, heat stroke, kidney failure and other dangerous health effects. That's why it's important to stay hydrated during sports practices and games.
The National Institute of Arthritis and Musculoskeletal and Skin Diseases recommends drinking 8 fluid ounces every 20 minutes, if not more often. That way, athletes can replenish all of the water that they've been sweating out.
If kids become hot and sweaty and start to feel dizzy, weak, confused or nauseous, they're body may be sending signals of dehydration. They should alert a coach, take a break and drink some water. In hot weather, it's also good to drink beverages with electrolytes to restore sodium and potassium levels in the body.
