Note: The heat index, also known as 'felt air temperature' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. 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 especially vital to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
