Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
