Note: The heat index, also known as 'apparent temperature' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
