Heat index

In September, the heat index is computed to be a sweltering 39°C (102.2°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. 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. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. 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. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
