Air humidity in closed spaces
People's health is affected strongly by the environment in which they live. One highly significant factor is the indoor climate in residential buildings. Air is a mixture of different gases, one of them being water vapour. However, the amount of water vapour which the air can contain is limited. The warmer the air is, the more water vapour it can hold. If the air is too moist then the standard of living can be seriously impaired by mildew, allergies and respiratory illness.
How does moisture get into the air? Our bodies emit moisture constantly into the room around us. Moisture is also produced in kitchens and bathrooms, by house plants, by outdoor humidity penetrating through the walls of a building and being stored in masonry, and so on. The relative air humidity rises if this more humid air is not replaced from time to time. If this does not happen, then condensation can form on cooler objects, or the air humidity can rise around cool objects. Condensed moisture provides an ideal breeding ground for mould and mildew. The results are health-damaging.
