Heat index

During February, the heat index is appraised at a burning hot 47°C (116.6°F). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
