Question: What dehydration means

Answer: Dehydration occurs when your body’s water content is too low. Here are some body signals that indicate you haven’t had enough fluid:

- headaches
- fatigue
- mood changes
- slow reaction times
- dry nasal passages
- dry or cracked lips
- dark coloured urine
- muscle cramps
- weakness
- confusion
- hallucinations.

If you experience any of these symptoms, you may need to increase your fluid intake.

If you don’t rehydrate, your physical and mental performance is likely to be affected. A loss of fluid equal to two per cent of body mass (for example a 1.4 kg loss in a 70 kg person) is enough to cause a detectable decrease in performance. A loss of fluid equal to more than two per cent means you risk nausea, vomiting, diarrhoea and other gastro-intestinal problems.

It’s not possible to train your body to handle dehydration, so don’t delay fluid replacement to ‘get used to dehydration’. When you need water, you need it.
