You’ll be able to stand a more vigorous workout
One of the many benefits of drinking water is that it will help with your workout. Muscles need a good balance of electrolytes like sodium, potassium, and magnesium to function properly. Without proper hydration, electrolytes can’t exchange as easily, and the muscles can lose plumpness and be more prone to cramping. “If you’re working on building muscle, you won’t get that intensity if you’re not hydrated because the muscles are demanding water,” says Bruning. Drink eight ounces of water before physical activity to stay hydrated. You probably don’t need to carry a water bottle during a light or moderate workout, but you should have water or a sports drink on hand for vigorous activity or when you’re exercising in the heat, says Bruning.
Your kidneys will function better
Kidneys flush waste from your body in the form of liquids and they need sufficient water to do that. If you’re chronically dehydrated, it could be harder for kidneys to do their job, and a blood urea nitrogen test could show you if they’re not functioning properly, says Bruning. Plus, without needing regular bathroom visits, a hard mineral could form and cause kidney stones, says Kelly Pritchett, PhD, RD spokesperson for the Academy of Nutrition and Dietetics. “When urine production is low, the kidneys are forced to concentrate the urine, meaning a heavy concentration of minerals,” she says. Don’t miss these surprising signs of dehydration.
You’ll get an energy boost
Many people don’t realize that one of the benefits of drinking water is that it helps your energy levels. Your body needs water to keep up its energy levels, which is why you might feel sluggish if you aren’t drinking enough water every day. “Some people turn to caffeine because they think they’re always tired, but something like caffeine won’t necessarily have beneficial effects on energy levels if they’re not hydrated as well,” says Bruning.
