Note: The heat index, also known as 'apparent temperature' or 'feels like', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
