11 Facts And 4 Myths About Water: Hydration & Health

Author: Rosemary Buckle, M.D.

Do you know what is the most popular drink in the United States? You might naturally think of the cheapest, most common, and oldest drink known to mankind: water.

If so, you’re right. But only until recently! It wasn’t until last year that water became, once again, the most popular beverage in the U.S. For several decades, soda held that top popularity slot. Now, however, the average American drinks 58 gallons of water per year, while soda intake per person is down to 44 gallons per year.

That’s good news, considering just how important a role water plays in our health. To learn more about the role of water, see the infographic below, shared from Medical Daily.

Proportions of Water in the Human Body

  • Approximately 2/3 of the body is made up of water.
  • 57-60% of body weight in the male body is water.
  • 79% of a newborn infant’s body weight is water.
  • The amount of water in the body decreases from birth to old age.

Benefits of Drinking Water

Drinking water has many benefits. It helps with…

  • Digestion
  • Regulating body temperature
  • Chemical reactions in the body
  • Joint lubrication
  • Flushing out waste and toxins
  • Lubricating the eyes
  • Body growth

Studies have also claimed water helps improve concentration levels, reduce headaches, improve joint and muscle health, improve physical performance, and improve emotional outlook.

Myths About Drinking Water

  • “You can’t drink too much.” In fact, overconsumption of water can be fatal. The American Chemistry Society claims that drinking six liters of water could be fatal in a 165-lb. adult male.
  • “Drink eight 8-oz glasses per day.” The source of this myth is unknown. Most recommendations call for more water than just 1.9 liters per day. The average male should drink 3.7 liters per day; the average female, 2.7 liters per day.
  • “Drinking water helps you lose weight.” While water might be a better response to some snack impulses, there’s nothing about drinking it that will cause weight loss.
  • “Only water will provide hydration.” Other fluids can help you hydrate and replenish minerals!

Your minimum water intake may be affected by your diet, age and weight, whether or not you are pregnant or breast-feeding, your medications, medical conditions and health issues, exercise and activity levels, and environment.
