Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
