A new study using telemetry to monitor hydration and temperature status found that the athletes own body adequately regulated temperature and found no relationship between hydration status and temperature. Temperature and measures of dehydration (sodium and urine concentration) stayed within normal ranges. Even large losses of fluid do not lead to heat illness.

As if the body would not protect itself given its sophisticated homeostatic mechanisms; mechanisms so complex they are still not fully understood. It is a grandiose claim that research or sports products can improve these evolved homeostatic mechanisms that serve not only we homo sapiens, but all mammals.

Professor Noakes smacks down the guidelines as “linked to an extensive marketing campaign, directed by the sports drink industry.”
