Why is drinking water so important?

Did you know that water is the most abundant nutrient in our body? Our body is approximately 60% water and our brain is 70% water. Our lungs are nearly 90%! Each day, our body must replace 2.4 liters (approx 2.5 quarts) lost through breathing, sweating, digestion. That’s a LOT of water!

Water helps transports nutrients and medications throughout the body. Water Benefits are:

  • Aids in metabolism
  • Prevents constipation
  • Facilitates digestion
  • Regulates body temperature

What happens when we are dehydrated?

  • Water controls your dehydration and can lead to heat shock, fainting and even death.
  • Your brain has priority to take water from the rest of your body when you’re thirsty.
  • Your heart has to work harder
  • Higher blood viscosity
  • Toxins accumulate
  • High blood pressure Blood clotting
  • Kidneys get overloaded, Toxins accumulate then they cannot be flushed, they can be damaged
  • Digestive problems
  • Constipation
  • Acid reflux
  • Indigestion

Estimating Fluid Needs:

Institute of Medicine (IOM) Food and Nutrition Board determined total water intake of: 2700mL/day for women 3700mL/day for men to meet the needs of the general healthy adult 11- 15 cups/ day.

What is dehydration: Loss of body fluid exceeds fluid intake OR Fluid intake fails to replace fluid loss. It has been reported that as many as one million elderly are admitted to the hospital each year with dehydration as one of the reasons for admission.
