Drink more fluids in hot climates, hot weather, or during activity in
hot environments to help prevent dehydration and decrease the risk of a
heat-related illness. Water or commercial sports drinks are good
choices.
Drinking sports drinks containing electrolytes and carbohydrates may
help support athletic performance during very strenuous activities. The
electrolytes provided in sports drinks may prevent muscle cramps caused by loss
of salt.
The temperature of the fluid can be cold as long as this does not
cause stomach cramps.
