When the temperatures rise, getting enough to drink is important whether you’re playing sports, traveling or just sitting in the sun.
Keeping the body hydrated helps the heart more easily pump blood through the blood vessels to the muscles. And, it helps the muscles work efficiently.
For most people, water is the best thing to drink to stay hydrated. Sources of water also include foods, such fruits and vegetables which contain a high percentage of water. Sports drinks with electrolytes, may be useful for people doing high intensity, vigorous exercise in very hot weather, though they tend to be high in added sugars and calories.
Hydration isn’t just important during physical activity. Sitting in the sun on a hot or humid day, even if you aren’t exercising, can also cause your body to need more fluids.
