Heat index

The heat index value during September is calculated to be a fiery hot 36°C (96.8°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
