Heat index

The average heat index in September is computed to be a blistering 43°C (109.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is found by incorporating humidity levels into the air temperature measurement. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
