Note: The heat index, also known as 'feels like' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
