Heat index

Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
