Summer Hydration


Summer is here! With the hot weather and people getting outside more often for various activities, it’s a good time of year to review the importance of staying hydrated.

How much water do you need to drink?

You should drink water every day. The general guideline has been six to eight 8-ounce glasses a day. Different people need different amounts. Most people stay adequately hydrated by drinking water when they are thirsty. Other drinks and foods help you stay hydrated as well. Fruits and vegetables contain water. Teas, coffee, and sodas have water content as well. Overall, it’s recommended that you limit caffeinated drinks as caffeine can cause you to urinate more frequently and feel jittery. Other drinks may have unwanted calories. Sports drinks can be helpful when you are exercising as they contain carbohydrates and electrolytes that can increase your energy level but watch the labels.
