Note: The heat index, also known as 'felt air temperature' or 'feels like', measures the perceived warmth when incorporating the humidity present in the air. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. 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 hold great significance to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Rising body temperatures due to excess heat retention could signify impending heat disorders.
