Hydration Tips & Guidelines

Drink a glass of water as soon as you wake up to kickstart hydration after hours without fluid intake.

Don't wait until you're thirsty. Sip water consistently throughout the day for optimal hydration.
🏃‍♂️ Exercise Hydration
Drink 17-20 oz of water 2-3 hours before exercise, and 6-8 oz every 15-20 minutes during activity.
🍎 Food Sources
About 20% of daily fluid comes from food. Fruits and vegetables are excellent sources of water.
🌡️ Hot Weather
Increase intake by 12-16 oz for every hour of activity in hot weather to replace sweat losses.
