Heat index

Throughout September, the heat index is appraised at a burning hot 48°C (118.4°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
