Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
