We’re mostly made of water, so it makes sense that whatever comes out, has to go back in to keep you properly hydrated and in order. While every body has its own needs, the general consensus is that you should be drinking at least eight 8-ounce glasses of water per day (calculate how much you really need). The benefits of drinking water are plentiful, but here are a few you should definitely know about.

Reduces Appetite

If you’re looking to cut back, drinking water before you eat your meals has also been shown to reduce appetite, especially in older people. So, for as much as you love those cookies or an extra slice of casserole, a pre-meal glass of water might help you cut down on eating more than you really need to keep you full.

Reduces Calorie Intake

Since water is free from everything, including calories, it’s linked to consuming fewer calories and added sugars versus what you would be consuming if you chose a sugary soda over water. Water really is the best way to hydrate, but there are other drinks that are good for hydration too, and some that aren’t so good.

Recovery From Exercise

Drinking water while you exercise is essential to refuel your body with the fluids you’re losing from sweat, but drinking after you exercise is just as important for rehydration. It might be tempting, but don’t go for caffeinated beverages which aren’t as effective for hydration. Here are the 10 best foods to eat before a workout.

Flush Out Toxins

Water flushes out toxins from your body and allows your kidneys to properly function by eliminating toxins and waste from bodily fluids and allowing your body to clear everything out without any problems. If you’re struggling to drink enough water every day, these tricks might help.

Boost Metabolism

Drinking water can help boost your metabolism, too. A study in the Journal of Clinical Endocrinology and Metabolism found that drinking about 17oz of water increases metabolic rate by 30 percent in healthy men and women. Mild dehydration can slow down your metabolism by as much as 3 percent, so keep drinking!

Aids Digestion

Properly digested food will leave you feeling comfortable instead of bloated, which is key especially if you’re working out regularly. Getting enough water is really important to prevent constipation and maintain a healthy gut. These ideas for flavored water will help you meet your daily water goals.

Pumps Up Your Muscles

Water keeps your muscles healthy and strong, as well as safe from tears and pulls, which are no fun. Water helps transport nutrients to muscles for fuel, is necessary to move and flex muscles and helps prevent cramping. Even a slight dehydration can result in a decrease in muscle strength.

Reduce Cravings

Some people confuse dehydration with hunger, so it’s likely you won’t crave as many unhealthy treats or snacks if you’re drinking water more frequently. Water isn’t a replacement for healthy snacks and meals, but might be able to help you steer away from unnecessary junk food.

Burn More Calories

Drinking cold water alone is a mini-workout! When you drink cold water, your body gets to work and starts burning calories to warm the water to match your body temperature. Keep in mind, though, it’s a really small amount and won’t move the calorie-burning needle in a substantial way, but every little bit helps! If you find plain water too boring, try infused water for more flavor and interest.
