Heat index

Always consider that heat index estimations are for light winds and places in the shade. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Rising body temperatures due to excess heat retention could signify impending heat disorders.
