For September, the heat index is evaluated at a torrid 98.6°F (37°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Note that heat index values are valued for light wind and location in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 extremely significant for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
