Heat index

For most parts of December, the heat index is calculated to be a scorching 41°C (105.8°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
