Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
