Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
