Damp and health problems
Damp in a house or other property can have an impact on the health of the residents and other
users of the building. The effects are most noticeable in residential properties, as the person would
be exposed to the damp on a regular basis.
Damp can encourage the growth of mould in a house, and many people find that they are allergic to
the mould spores that are produced and released into the air. This can cause respiratory problems
when the spores are inhaled, such as chest infections and worsening of chronic conditions such as
asthma. It is important to keep the house well-ventilated as this can help to reduce the risk of
mould growth and will allow the spores to leave the property. Mould in a property can also increase
the risk of developing infections such as the flu, and will generally make the symptoms last longer.
The main health risk of living in a damp house is respiratory illness, and in extreme cases this can
lead to conditions such as pneumonia and bronchitis. It also increases the risk of skin allergies
through contact with the mould on a regular basis. Studies have shown that the number of cases of
asthma double when people are living in homes affected by damp, particularly among students as
these houses are more likely to be poorly maintained. Many people living in damp conditions also
suffer with frequent coughs and colds, and will have a near-constant runny nose as a result.
The damp conditions allow bacteria to thrive as well as the moulds, and this can be a source of
infection for the residents of the property. Again, the most common conditions are respiratory,
though bacteria can cause a wide range of illnesses, and transmission frequently occurs through the
air.
Proper maintenance is vitally important for reducing the illnesses caused by damp, though many of
these conditions can be improved by removing the mould from the affected surfaces, which will
usually be found in kitchens and bathrooms. It may also be beneficial to use a dehumidifier,
particularly in these rooms, which will help to remove excess moisture from the air.
