Note that heat index values are valued for light wind and location in the shade. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Rising body temperatures due to excess heat retention could signify impending heat disorders.
