Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
