Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
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. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
