Drink plenty of water before, during, and after you are active. This is very important when it’s hot out and when you do intense exercise to help prevent dehydration and decrease the risk of a heat-related illness. Water or commercial sports drinks are good choices.
Drinking rehydration drinks containing electrolytes and carbohydrates may help support athletic performance during very strenuous activities. The electrolytes 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.
