Humidity is the amount of water vapor in the air. Too much or too little humidity can be dangerous. For example, high humidity combined with hot temperatures is a combination that can be a health risk, especially for the very young and the very old. Humidity plays an important role in our daily weather.
Relative humidity is the ratio of water vapor in the air compared to the amount of water vapor the same air at the same temperature holds when it is saturated. Hence if the amount of water vapor in the air remains constant and the temperature falls the relative humidity rises.
