For clarity, heat index numbers account for light winds and areas under shade. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.

Enhance your sun protection with tightly woven, yet airy clothing.
