Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. 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.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
