Is Your Drink (De)Hydrating?

Foods and beverages affect hydration in different ways, depending on factors such as water content and other ingredients.

Foods and beverages that include sodium are the most dehydrating, whereas plain water or herbal teas are the most hydrating. Sugar increases your body’s water needs due to the amount of water required to metabolize sugar, so while sugary drinks may taste refreshing at first, they actually can be dehydrating. Caffeine can have some diuretic effects, though a small amount, such as 1-2 cups of coffee or tea, won’t have significant dehydrating effects. Drink more than that and you will see some dehydrating effects.

Here’s a quick guide for how your food or beverage will affect hydration.

  • Herbal teas

*Sugar-Sweetened Sports Drinks: For anyone engaged in moderate to high intensity exercise that lasts an hour or longer, sports drinks are more appropriate than water in order to replace carbohydrate stores and electrolytes.

Everyone’s hydration needs are different, and your needs depend on your age, physical activity level and your environment. Active people that live in warm climates will need more water than those that are not very active and live in cooler climates, for example. Stay hydrated by drinking water regularly throughout the day.
