Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off.
