Water's important role in the body

Water helps nearly every part of the human body function.The human body contains over 75% water. Water is the transport system which moves nutrients around the body as well as carrying waste out of the body. Water breaks down food, keeps your body temperature balanced and keeps you skin elastic. We can live for weeks without food but only a few days without water. The following are just some of the important things water does in the body:

  1. Liquid in a range of body temperatures
  2. Media for biochemical reactions
  3. Efficient cooling effect
  4. High latent heat prevents freezing
  5. Water is required for perspiration.
  6. Carries nutrients and oxygen to all cells in the body.
  7. Moistens oxygen for breathing.
  8. Protects and cushions vital organs.
  9. Helps body absorb nutrients.
  10. Removes waste.
  11. Cushions joints.

 

Water Facts

The human body contains between 55-75% water depending on the ratio of body fat to muscle.

  1. The human brain is 75% water,
  2. Blood is 92% water.
  3. Muscles are 75 % water
  4. Bones are 22% water

Water is vital for body temperature regulation, therefore fluid replacement is vital. During summer when the temperature increases, your body requires even more fluid to maintain it's normal body temperature. Even when there is zero intake of water there are always unavoidable losses.

Water In: Solid Foods (34 ozs.), Metabolic Water (10 ozs.) and Beverages (34 ozs.)

Water Out: Evaporation (min 34 ozs.), Sweat ???, Faeces (3+ ozs.) Urine?

 

Dehydration

Remember! Although thirst indicates a lack of fluid, it is not a reliable measure of water need. It is important to pay attention to the signals of water loss and minimise risk of dehydration before thirst sets in. Establishing a strong fluid habit is important for everyone.

  1. 1-5% Thirst, vagueness. Discomfort, increased pulse, nausea
  2. 6-10% Dizziness, headache, laboured breathing, walking difficulties
  3. 11-20% Delirium, twitching, inability to swallow. Severe lack of water, or extreme dehydration, when more than 1/2 to 2 litres of fluid are lost can be life threatening.

 

Benefits of Good Hydration

  1. Increases physical and mental alertness
  2. Extra moisture of all systems
  3. Energy Systems
  4. Protection - Cancer Research!
