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. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
