Christmas tree allergy, a cause for your sneeze.

Sunday, December 25th, 2011

For many years indoor Christmas trees have bee suspected to be a source of allergen induced asthma, rhinitis and respiratory problems during the period from mid December to early January. It was thought that coniferous tree pollen, incidental grass and weed pollens on the tree and oleoresins secreted by Fir trees were to blame.  However a recent study in the US, has found that coniferous Christmas trees carry and sustain significant amounts of mould spores.  Common allergenic moulds such as Cladosporium, Aspergillus, Alternaria and Penicillium are found in significant amounts on Christmas trees and raise indorr mould levels from 300 to 5000 spores per cubic metre of indoor air.  Exposure to the spores trigger chronic respiratory conditions such as allergic asthma, rhino-sinusitis and chronic bronchitis (COPD).  Spraying the tree with a mist containing household bleech such as Milton (sodium hypochlorite) kills off moulds and prevents their growth on the trees and subsequent indoor mould contamination.

Christmas allergies

Tuesday, December 22nd, 2009

Although some people have a general aversion to all things Christmas, this is not truly an allergy.  But for those genuinely allergic people, the festive season can be a frankly dangerous period. Unprecedented numbers of children have developed nut, fruit and general food allergies in recent years as the allergy pandemic takes hold of our lives on a scale that outstrips global warming and climate change.  Christmas time is a highly risky period for these people.  Consider the contents of Christmas foods such as cakes, mince pies, puddings, nuts and all those special treats abundantly available during the Festive Season.  No wonder it’s a worrying time for parents and allergy sufferers. Even the traditional Christmas tree may be a hotbed of allergens, distributing pollen, moulds and resin inside the home.  Whilst a synthetic tree may be as problematic for it may contain allergenic chemicals such as formaldehyde and isocyanates.  These chemicals can trigger off asthma, rhinitis, skin allergies and allergic conjunctivitis.

On a more positive note, the traditional Christmas turkey is a particularly low allergy-risk protein and if served together with low allergy-risk vegetables such as rice, sweet potato, cooked carrot, parsnip, beetroot and peas, this can make a particularly suitable Christmas meal for allergy-prone children and their parents. Finish off the festivities with a hypo-allergenic dessert of cooked pears or apricots. The process of cooking foodstuffs tends to reduce the allergy provoking effects on the immune system by slightly changing the molecular structure of the food.  If in doubt about allergy-risk friends and visitors always keep a good supply of antihistamine medication on hand just in case…………….
