Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. 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 extremely significant for babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. An elevated level of relative humidity hinders evaporation, leading to decreased heat elimination from the body, inducing a sensation of excess heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
