We all know we should be drinking water, right? I mean our body is composed of about 65%. But why? It’s commonly recommended to follow the 8×8 rule. Drink eight 8 ounce glasses per day, but there are some benefits to staying well hydrated that aren’t talked about that often. We have all heard that drinking water helps your skin stay hydrated and clear (celebrities often site it as their “beauty secret”), but did you know that it’s good for brain function too? Yep, water does a lot more than just keep your skin glowy. We’ve rounded up some of the top benefits to drinking lots of H20 in addition skin health.

#1. Prevents headaches.

One of the main causes of headaches is dehydration. If you are prone to frequent headaches, try upping your water intake. This is a natural, side-effect free way to help prevent or treat those pesky headaches.

#2. Improves digestion.

Drinking water during and/or after a meal can help aid in digestion. Water helps break down the food that you consume, thereby helping the body absorb nutrients better. It’s also necessary to digest soluble fiber, which helps soften stools, and make them easier to pass. Sorry, TMI but it’s true. This can, in turn, aid in waste elimination and boating.

#3. Increases energy and aids in weight loss.

Dehydration can affect motivation and make you feel fatigued. Muscle is about 80% water, so it makes sense that they are more sluggish if not properly hydrated. Drinking water can also boost your metabolic rate which means it can help you lose weight. Consuming at least 2 liters of water a day can boost your energy expenditure by 96 calories. Increased energy and weight loss? Yes please!

#4. Improves brain function.

Your brain is severely influenced by your hydration status, and even mild dehydration can impair brain function. Studies have shown decreased concentration, impaired mood, and memory loss due to lack of hydration. Stay smart and drink water;)

#5. Prevents hangovers.

This may seem obvious to some, but staying thoroughly hydrated may be a way to alleviate or prevent hangovers. Alcohol is a diuretic, which means it makes you excrete more water i.e. pee a lot. Having a glass of water in between drinks and one big glass before bedtime is a good way to help reduce hangover symptoms. While dehydration is not the only factor that produces a hangover, it is the culprit for dry mouth, thirst, fatigue, and headache.

Now go drink a big glass of water!
