If fluid lost as sweat is not replaced dehydration occurs. As a result, the consumption of fluid is critical to the safe and effective functioning of the body during exercise.

The variability in sweat rate between individuals, sports and environmental conditions emphasise that there is no single ‘one size fits all’ recommendation for fluid intake.

Dehydration, by as little as 2% of body mass (1.4 kg for a 70 kg individual), can reduce both mental (concentration, focus, reaction time) and physical (endurance) performance.
