Question

How does relative humidity affect the comfor of people? Can you explain the physiological reason for this?

Answer 1

the lower the relative humidity, the faster water can evaporate from your skin. Evaporation is a cooling process, so you'll cool off faster in less humidity, given the same temperature

Answer 2

People feel uncomfortable when both the temperature and the humidity is high. That is where the heat index comes into play. People are less able to sweat in higher humidities because the air is more saturated, which means less moisture can be added to the air.

Answer 3

Water vapour in the atmosphere  is a powerful absorber of the heat radiation(terrestial radiation) emitted by the earth's surface.Thus it traps the heat near the surface and makes the atmosphere(near the surface) warm and sultry.Hence, less evaporation takes place over the body leading to less cooling of the body.So,you feel uncomfortable and the intensity of this uncomfortable feeling is given by what is called 'Heat index' which is an apparent temperature(more than the actual temperature) derived by combining the actual temperature and the relative humidity.
