Note: The heat index, also known as 'feels like' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
