Heat index

The heat index value for September is calculated to be a blazing hot 45°C (113°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.
Know that the heat index computations account for shaded terrains and slight winds. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. 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. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Persist with safeguards and heed sun safety doctrines. Keeping sunburn at bay is of prime importance. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
