Heat index

During August, the heat index is computed to be a blisteringly hot 43°C (109.4°F). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.
Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived 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. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. 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.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
