The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
