Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
