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 are especially crucial for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
