Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
