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. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
