Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
