Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
