What is meant by humidity?

The term humidity has often been used as a stand in for things like fog or mist; these are all examples of atmospheric water vapor content. The term is also casually used to describe the amount of moisture in the air. This may be confusing, but there is actually a big difference between these two concepts, which we will explore now.

Humidity is defined as the saturation of air with water vapor, and it can be described using several different measures including relative humidity, absolute humidity and dew point.

Air consists of gases and water vapor.30-50% of wetness in the air is not bad but if the proportion keeps increasing in the air that can have a bad effect on human health. Humidity in the air also effects the skin as the pores of the skin are clogged and skin can't breathe leading to acne and other skin infections.Warm or hot air can hold more water in the air and this can make humans sweat more than normal and cause exhaustion.
