The Importance of Water
Drink water to stay healthy
There is a lot of talk about water and how necessary it is to maintain life and health. ?An adult?s body contains about 70% water. It is a major part of every cell, tissue and organ. It is crucial in almost all body functions and without it we would die very quickly.
What does water do in our body?
? Maintains body temperature ? it takes a lot of energy to raise or lower the temperature of water so the body is able to maintain a relatively stable temperature.
? Cools the body ? during exercise, illness or on a hot day, body temperature often rises which triggers sweat production. The sweat evaporates off the skin which cools the body.
? Balances electrolytes ? every cell needs a certain balance of electrolytes (ions that conduct electrical currents), as do extracellular fluids. The body maintains its electrolyte balance by excreting water and triggering thirst as necessary.
? Provides body fluids ? blood is mostly water. Muscles, lungs and brains all contain a lot of water. Water is a major part of synovial fluid (the lubricant that protects joints and allows them to move easily), amniotic fluid (that protects unborn babies), mucous, tears and saliva.
? Maintains pH levels ? carbon dioxide reacts with water, making carbonic acid, which then detaches to make hydrogen and bicarbonate which increases the body?s acidity and lowers the body?s pH ? a very finely balanced thing!
? Gives cells their shape and stability.
? Transports oxygen and nutrients through the blood.
? Help elimination of waste through urine and faeces.
You lose water through breathing, sweating, urination, bowel movements and so on. You lose more when you?re active or unwell. Some medications, alcohol, caffeine etc may increase your water loss. Other causes include, vomiting, diarrhoea, fever, burns and diabetes.
