Without enough water, skin, the largest organ in the body, can become dry and wrinkled. Do you drink enough water every day?

Percentage of Total Body Water Lost

In a day’s work, the body loses about 8 to 12 cups of water and all of that fluid needs to go back in. When you become dehydrated, your blood loses volume and your heart can’t circulate blood effectively. The eventual result… heart failure.

  • Decreases your sweat rate
  • Increases your core temperature (causing exhaustion from heat strain)
  • Decreases maximal cardiac output (i.e., the highest pumping capacity of the heart that can be achieved during exercise)

NOTE: A loss of only 20% of total body water could result in death.
