Heat index

February's heat index is calculated to be a sweltering 38°C (100.4°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
