Long-lasting activity may cause heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important 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.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. 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. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
