Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
