Many people might consider me a water fanatic, especially when it concerns my patients and their recovery. Most of us do not take the time to research the effects of water on our bodies. I decided to prepare this blog post with that in mind. Your car will not run without fuel and neither will your body. Water is essential for survival, and the human body can only do without water for about one week. Compare this with the ability to survive for a month without food, and it is easy to appreciate the importance of water.

  • The Human Body: ~60% water

  • Blood: ~92% water

  • The Brain & Muscles: ~75% water

  • Bones: ~22% water


These values probably surprise some of you. Water has an undeniable role in the proper functioning of our bodies and systems. I feel like most of us undoubtedly know that water is important, but rarely heed advice to drink more water. With this assumption, check out some of the many benefits of staying well hydrated:

  • Water helps to maintain healthy body weight by increasing metabolism and regulating appetite.

  • Water leads to increased energy levels. The most common cause of daytime fatigue is actually mild dehydration.

  • Drinking water can significantly reduce joint and/or back pain.

  • Water leads to overall greater health by flushing out wastes and bacteria that can cause disease.

  • Water can prevent and alleviate headaches.

  • Water naturally moisturizes skin and ensures proper cellular formation underneath layers of skin to give it a healthy, glowing appearance.

  • Water aids in the digestion process and prevents constipation.

  • Water is the primary mode of transportation for all nutrients in the body and is essential for proper circulation.

So the next time you reach for the afternoon cola or energy drink, try a large glass of water. I think you will be surprised how your body responds to a full tank!
