Heat index

In February, the average heat index is appraised at a torrid 36°C (96.8°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Understand that the heat index values take into account shaded locations and mild winds. 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 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Adhere to precautions and respect sun safety doctrines. Avoiding sunburn is vital. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes. Heads up! UV intensity is amplified by reflections from water and sand.
