Heat index

During January, the heat index is calculated to be an extremely hot 42°C (107.6°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
