Note: The heat index, also known as 'feels like' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
