Heat index

Take note of the fact that heat index values are based on shaded circumstances with light airflows. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
