Relative humidity indoors : factsheet.: H144-33/2016E-PDF

"Besides oxygen, the air we breathe also contains water vapour. The amount of water vapour in the air can affect your comfort, your health and the structural integrity of your home and its contents. Humidity is the amount of water vapour in the air. The relative humidity (RH), which is expressed as a percentage, is the amount of water vapour the air contains compared to the maximum possible at that temperature and pressure. The RH is affected by temperature, which explains why differences can be observed according to seasons. In general, RH levels in homes tend to be lower in winter and higher in summer"--P. [1].
