Note: The heat index, also known as 'feels like' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly 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.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
