Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 particular importance for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
