Note: The heat index, also known as 'feels like' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
