Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people.

Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
