Have you noticed a pattern of illness over Christmas? Although there can be a variety of reasons for this, one likely culprit is the Christmas tree and, judging from the article below, the longer you have the Christmas tree in the house the higher the mould spore count. So if you feel you cannot live without a real Christmas tree this year remember that if you bring it in two weeks before Christmas the mould spore count will be very high by Christmas Day and will be certain to cause problems for anyone allergic to mould and may cause particular distress to asthma sufferers.
