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, CSSD, 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 you 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.
Your skin will glow
When your skin cells aren’t getting the water they need, they’ll start to wither and shrink. But if you drink enough water, your skin will look more lustrous and get plumpness that erases fine lines that form when you’re dehydrated—just don’t expect it to make you look 20 years younger, says Bruning. “Wrinkling is a natural process of aging, and it won’t erase those wrinkles,” she says. “It’s not that miraculous.” This is the exact amount of water you should be drinking every day.
