Take note of the fact that heat index values are based on shaded circumstances with light airflows. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
