Heat index

For most parts of February, the heat index is computed to be a scorching 44°C (111.2°F). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.
Keep in mind the heat index values are meant for areas in shade and with light wind. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the feeling of heat when considering both air temperature and humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
