Note: The heat index, also known as 'real feel' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. 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.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
