We are constantly told that drinking 2-3litres of water every day is important. But why? As humans, we need water to survive. With the human body consisting of approximately 60% water, including the brain which is approximately 70% water, and the lungs roughly 90% water, it is crucial that you keep hydrated in order for the body to function at its optimum level.

Adequate hydration:

  • Removes toxins from the body
  • Helps with digestion and metabolic function
  • Provides elasticity to muscles and joints

Inadequate hydration:

Water is actually more important for your body than food. While you can survive without food for one month, you can only live without water for approximately one week.

A lack of water in your body reduces your blood volume, and therefore the amount of blood circulating. As a result, the heart is forced to pump harder and faster in order to deliver oxygen-bearing blood around the body which can affect the regulation of body temperature and also inhibit muscle contractions.

During exercise the body maintains optimal body temperature by sweating, resulting in a loss of body fluid. Replacing these fluids is necessary to reduce the risk of heat stress, maintain normal muscle function, and prevent performance decreases due to dehydration.

Some early indicators of dehydration include dizziness, irritability and headaches. If it progresses you may become clumsy, exhausted and you could experience nausea and vomiting.

*As a general rule, to remain adequately hydrated: for every 1kg of body weight, you would need 0.033 litre of water EG: 100kg person = 3.3 litres of water. 75kg person = 2.4L. 50kg person = 1.65 litres of water per day.
