Heat index

The average heat index in September is computed to be a fiery hot 98.6°F (37°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
When referencing the heat index, its values are suitable for shady environments and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
