Heat index

Understand that the heat index values take into account shaded locations and mild winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
