While water is an essential part of hydration, try coconut water for a deliciously refreshing alternative that does more than just hydrate. Coconut water boosts your metabolism, keeps your body cool, rehydrates the cells, detoxifies and fights viruses, and transports oxygen and nutrients throughout the body, too. It’s also a rich source of electrolytes (and particularly high in potassium), which we need to replenish when exercising in the heat.
