Heat index

Note: The heat index, also known as 'apparent temperature' or 'feels like', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
