Note: The heat index, also known as 'feels like' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are essentially critical for children. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
