During exercise, how much water should be consumed per hour depending on sweat rate?

• A. 4-8 oz every 15-20 minutes
• B. 4-8 oz every 15-20 minutes or 16-32 oz per hour depending on rate of sweat
• C. 16-32 oz per hour regardless of sweat rate
• D. 64 oz per hour

Answer: (B)

During exercise, your fluid strategy should match how much you’re losing in sweat, so you replace losses without overwhelming the gut. Sip about 4-8 ounces of water every 15-20 minutes, which amounts to roughly 16-32 ounces per hour. Because sweat rate changes with effort, temperature, humidity, and individual differences, adjust within that range based on how much you’re sweating. If you’re sweating a lot, toward the higher end; if sweating less, toward the lower end. Options that fix the hourly amount or push very high intake don’t fit real-world needs and can cause stomach upset.
