Think you’ve got enough to worry about in the run-up to Christmas? Spare a thought for people with allergies, for whom the festive season is fraught with danger. But, with a little consideration, you could prevent an allergic reaction, and even a trip to Accident & Emergency.
1 Real Christmas trees can contain moulds, a health hazard for those allergic to them, while the sap can trigger skin reactions. The mould content is highest when the tree is cut some time in advance and kept in a moist atmosphere. After buying the tree, it helps to store it in a dry place like a garage, and then shake it before bringing it indoors. Note that, once the tree is inside, mould spores can grow within two weeks. For those with symptoms, fake trees may be the answer.
2 Mistletoe allergy is uncommon, though it can cause skin reactions in some people. The main danger comes from the kiss. Proteins can linger in saliva for several hours, so a snog can deliver a sizeable dose of nuts or whatever else the person last ate. Those with food allergies may find their luck running out, just when they thought it had come in.
3 Problems with latex are on the rise. About 4% of the general population is allergic to latex (the natural type from rubber), while nearly 10% of healthcare workers are. The incidence is growing because gloves are more often used for procedures which were done with bare hands in the bad old days. What has this to do with Christmas? Balloons and most condoms contain latex, and both may feature at the seasonal office party.
4 Alcoholic drinks can lead to allergic reactions. There are often nuts in speciality beers, and there’s obviously dairy in Irish cream liqueurs. There’s even almond oil in Bombay Sapphire gin, as the Anaphylaxis Campaign reminded me. Besides, alcohol can lower your guard and make you blasé about risk. And large amounts of alcohol tend to worsen allergic reactions.
5 Presents that smell nice, like bath oil, soaps, hand creams, and reed diffusers, may contain almond oil or other essential oils. These cause no trouble for most people, but they can trigger nasty reactions in those with allergies to the ingredients.
6 Festive candles are, again, mostly harmless, unless you’re careless enough to start a fire. But, for those with allergies, the soya present in some posh candles can be an issue. Candles may also contain pine, a potential problem for anyone allergic to pine resin.
7 The poinsettia plant is related to euphorbia (spurge). It’s not often an allergen, but it can be, especially for those with latex allergy. Symptoms include rash, wheezing, and shortness of breath. It’s wise not to have a poinsettia if you’re latex allergic.
8 Chocolate can contain dried fruits and nuts (which you may not spot if it’s in the form of a paste). It usually also contains soya lecithin. If you have a food allergy, check the label before indulging – if, that is, the label is anywhere to be seen. This can be a problem when chocolate treats are unwrapped and passed around on a plate at Christmas.
9 Sulphites are food preservatives commonly used in sausages, as well as in many pickled foods, dressings, and soft drinks. Some people react to sulphites with asthma symptoms or an urticarial rash. In most cases, the reaction is a sensitivity rather than an allergy. But occasionally there is a true allergy, with a severe reaction called anaphylaxis.
10 Fancy turkey stuffing can contain a multitude of allergens, including pecans and hazelnuts. One of the most widespread ingredients is celery. Although allergy to celery seems fairly rare in the UK, when it does occur, the reaction can be severe and may lead to anaphylactic shock.- see more about anaphylaxis.
11 The traditional Christmas pudding is full of nuts, an obvious problem to those with an allergy to them. But it is possible to source tasty nut-free versions in most large shops.
12 Christmas cake, as a rule, contains nuts. It’s easy enough to study the ingredients when out shopping and choose a product that doesn’t contain a particular nut or fruit (though it’s impossible to do without almonds if you want stollen or any other cake with a marzipan layer). If you have a nut allergy, visiting friends and family can still be risky, though. It’s not always enough to avoid a food that’s a trigger. There may be cross-contamination, which can be critical with severe allergy.
This list of Yuletide allergies is obviously far from inclusive, so please take care and have a happy, healthy Christmas.
I’ll be back in the New Year. Meanwhile, for more information about allergies, including anaphylaxis, visit the Anaphylaxis Campaign.
