In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
