Heat index

For September, the heat index is evaluated at a very hot 98.6°F (37°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Understand that the heat index values take into account shaded locations and mild winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
