Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', takes into account both air temperature and humidity to illustrate what people actually feel. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level 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 are highly critical to babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
