Christmas tree preparation

If you start sneezing as you approach a decorated tree, you should know that the cause could be Christmas tree syndrome. Here’s what it is

Bad news: the star of Christmas decorations could be responsible for your runny nose. Christmas tree syndrome is a sad reality that can trigger symptoms of seasonal allergy such as hay fever, during the Christmas period.


Clogged or runny nose, cough, shortness of breath, conjunctivitis, irritated eyes, watery eyes, tiredness, chest pains, sleep disorders … all the features of allergic rhinitis . In severe cases, children with asthma may suffer from a severe crisis that requires an emergency room visit.

The cause

When the tree grows outdoors, mold can settle on it. Once placed in the home, in a warmer environment, these microorganisms can grow and colonize the room through the spores. An American study has identified the presence of 53 types of mold in 26 different Christmas trees. The longer the Christmas tree remains in the house, the higher the rate of mold spores. Chemicals such as artificial snow or preservatives can also cause reactions. It is therefore likely that people with allergies will develop rhinitis symptoms.


The simplest technique to overcome the problem is … to ban Christmas trees. The artificial versions or the alternative and ecological decorations can limit the risk of allergies. You can also carefully wash your tree and let it dry outside before putting it back in the house as soon as it is dry.

If you choose an artificial fir tree, remember to wash it or clean it with a vacuum cleaner, because dust and mold can lurk there too. All the ornaments must be clean, because the dust attracts the mold.

To alleviate the symptoms, it is possible to connect an air purifier in the room where the tree is located and minimize exposure by keeping the fir tree for 4-7 days at home. Children with allergies or asthma should take a test for tree molds to avoid accidents.
