Content: Smoking and cigarette fumes - if you smoke and have asthma, you should make every effort to stop. See a practice nurse for help if you find it difficult. Passive smoking can make asthma worse too. Even where adults smoke away from the presence of children, smoke on clothes, hair, etc, may make asthma worse. All children deserve to live in a smoke-free home - in particular, children with asthma. Other fumes and chemicals - for example, fumes from paints, solvents and pollution. The increase in air pollution may be a reason why asthma is becoming more common. Details about current levels of air pollution, are available from The Daily Air Quality Index, which can be found on the Department for Environment Food and Rural Affairs (DEFRA) website (see further reading for link). Certain pillows and mattresses - feathers in pillows may trigger symptoms. It is thought that some people develop asthma symptoms from chemicals (isocyanates/methyl ethyl ketones, etc) that are emitted in very low quantities from memory foam pillows and mattress toppers.
