Think of what you need to survive, really just survive. Food? Water? Air? Facebook? Naturally, I'm going to concentrate on water here. Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human adult body is water.

According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.

Each day humans must consume a certain amount of water to survive. Of course, this varies according to age and gender, and also by where someone lives. Generally, an adult male needs about 3 liters per day while an adult female needs about 2.2 liters per day. Some of this water is gotten in food, the rest we need to drink. 1

Here are 5 surprising reasons we all need to drink more water.

 

1. Clearer Skin

Certain toxins in the body can cause the skin to inflame, which results in clogged pores and acne . While science saying water makes the skin wrinkle free is contradictory, water does flush out these toxins and can reduce the risk of pimples. source

 2. Brain Booster

A study in London found a link between students bringing water into an exam room and better grades, suggesting H2O promotes clearer thinking. While it’s unclear if drinking the water had anything to do with a better score, it doesn’t hurt to try it out! source

3. Balance of Body Fluids

Your body is composed of about 60% water. The functions of these bodily fluids include digestion, absorption, circulation, creation of saliva, transportation of nutrients, and maintenance of body temperature. source

4. Manages Headaches and Migraines

If you have a headache or migraine, the first thing that you can do to get some relief is drink plenty of water. Headaches and migraines are often caused by dehydration.

In a study published in the European Journal of Neurology, researchers found that increasing water intake helped reduce the total number of hours and intensity of headaches in the study participants. source

5. Helps Burn More Calories

Most of the studies listed below looked at the effect of drinking one, 0.5 liter (17 oz) serving of water.

Drinking water increases the amount of calories you burn, which is known as resting energy expenditure (4).

In adults, resting energy expenditure has been shown to increase by 24–30% within 10 minutes of drinking water. This lasts at least 60 minutes (5, 6).

Supporting this, one study of overweight and obese children found a 25% increase in resting energy expenditure after drinking cold water (7).

A study of overweight women examined the effects of increasing water intake to over 1 liter (34 oz) per day. They found that over a 12-month period, this resulted in an extra 2 kg (4.4 lbs) of weight loss (8). source

Quick hacks for drinking more water:

  • Drink half your body weight in ounces of water (if you weight 120lbs, drink 60oz of water each day).

  • Carry a bottle everywhere with you as a reminder to keep drinking.

  • Try adding different fruit and herbs to your water for a refreshing treat. 

  • Drink water and other fluids until you urinate frequently and with light color.
