Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
