Note: The heat index, also known as 'felt air temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. 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 heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
