10 Benefits of Staying Hydrated

The adult human body is made up of about 60% water. This is as high as 73% in the heart and brain, 83% in the lungs and even 31% in the bones! Despite this most of us are only drinking 5.5 of the recommended 10 cups of water each day. Not drinking enough water can have significant effects on your physical and mental well-being as well as your ability to perform in your daily activities at home and at work.

The rule of thumb is, if you’re thirsty, you’re already dehydrated.”
