Heat index

In September, the average heat index is computed to be a very hot 38°C (100.4°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. 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 particularly meaningful for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. 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 risks increase with rising body temperatures, especially if heat release isn't efficient.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
