The body uses water to help dissipate heat through sweat and evaporation of sweat. Water lost as sweat must be replaced through water consumption to help the body maintain temperature regulation. During moderate activity, the CDC recommends drinking at least 1 cup of water every 15-20 minutes to replace water lost through sweat.
Sports drinks are likely unnecessary to replenish the body’s electrolytes when adequate hydration is combined with regular meals. However, sports drinks may be beneficial to help balance the body’s water and electrolytes when tasks conducted under hot temperatures result in prolonged sweating over several hours.
Limit consumption of energy drinks, alcohol, and caffeine-containing beverages such as coffee, tea, and soda. These beverages can contribute to dehydration, increasing the risk of heat illness.
Staying hydrated starts before work then continues throughout the day and after work. Attention to personal hydration decreases the risk of heat illness and other risks associated with chronic dehydration, such as kidney stones.
