Young ones are generally at greater risk than adults due to their limited sweating ability.

In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
