Note: The heat index, also known as 'feels like' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. 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 are especially vital to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
