It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
