Aussies warned about little-known 'syndrome' caused by Christmas trees
Both artificial and real trees can pose serious risks, experts are warning.
With the festive season underway, health officials are warning Aussies everywhere to be aware of the little-known dangers associated with Christmas trees, as the ornament-adorned displays are erected in homes across the country.
Whether you dust off your tree from 11 months of storage, or prefer to buy the real deal each year, experts say the threat of the so-called "Christmas Tree syndrome" — an allergic reaction that can cause wheezing, sneezing, coughs, sore eyes and even potentially serious asthma attacks— remains the same.
Both real and artificial trees pose risks to vulnerable people
With the condition estimated to affect some six per cent of the population, particularly those with allergies and existing asthma conditions, Australians are being warned to be thoughtful when setting up the tree. One study found more than 50 kinds of mould were detected on samples of Christmas trees put forward by researchers.
“Real Christmas trees like cypress and pine can trap high amounts of pollen from other plants before they are cut down, and as the cut tree dries out, it releases the pollen which becomes airborne inside the house," National Asthma Council Australia's Professor Sheryl van Nunen said.
“The pollen and mould can cause ‘Christmas tree syndrome’, which can trigger asthma and hay fever symptoms and causes wheezing, sneezing, disrupted sleep, and possible severe asthma attacks."
Van Nunen added that while artificial trees can be a safe solution to allergens found in pollen, they also come with their own risks.
“Artificial trees can be a safe alternative but, if used year after year, they accumulate dust or mould, which may be invisible to the naked eye," she added.

“Even the most exciting part of the Christmas tree tradition — decorating — can put you at risk too if festive decorations have become dusty in storage.
“You can reduce the risks by simply hosing off the tree before you bring it in the house and letting it dry, as you will greatly reduce the amount of pollen and dust."
To reduce any potential dangers of real trees, van Nunen encouraged Aussies to also hose them down before bringing them into the house to help wash off any allergens, and to cut 2.5cm off the bottom so they can be watered, keeping them from drying out.
Give "a good shake" to artificial trees outside before you put it up inside, she continued, urging people to unpack the tree and decorations outdoors and vacuum them as you get them out of the box.
