Itchy eyes? Your Christmas tree could be to blame, expert warns

They bring a touch of cheer into any home – but your Christmas tree could also be triggering a runny nose, sneezing, coughing and itchy eyes, an expert has warned.

Pharmacist Noel Wicks says your festive centrepiece could spark a phenomenon called Christmas Tree Syndrome.

Symptoms often mimic hay fever and, in the worst cases, can lead to infections such as conjunctivitis, he cautioned.

And the issue isn’t limited to real trees – as fake versions can also cause problems.

‘If you find your eyes are having an allergic-type reaction, like red, itchy or watery eyes, it could be the Christmas tree in your house,’ Mr Wicks, an advisor to eye drops company GoldenEye, said.

‘It’s important to treat the symptoms straight away, to stop them from progressing further and potentially spoiling Christmas.

‘In some cases, irritation can lead to blepharitis or even styes, as the urge to rub itchy eyes can introduce infection.’

However, there are some simple steps people can take to reduce their risk – including shaking the tree before bringing it inside.

Most of the Christmas Tree Syndrome reactions are caused by pollen, mould and dust, Mr Wicks said.

Real trees collect pollen outdoors before being cut, meaning they can bring it into the home.

Another culprit is mould that lives on the trees and thrives in warm indoor environments, especially when the heating is on.

Previous studies have found dozens of types of mould on Christmas tree samples, which can trigger red, watery eyes and breathing difficulties.

The characteristic tree scent comes from terpenes in the tree sap, and some people are allergic to those compounds, Mr Wicks revealed.

Meanwhile farm chemicals can also act as irritants, triggering hay fever-like symptoms.

Dust mites, one of the most common respiratory allergens, can be carried into the house on artificial trees as well as on decorations and lights.

These tiny creatures are linked with triggering or worsening symptoms of asthma and eczema, and can also lead to sneezing, a runny nose and irritated eyes.

Ways to prevent or manage Christmas Tree Syndrome include wearing a mask when getting stored decorations out, to avoid dust and mould inhalation.

If possible, you should hose down your Christmas tree before bringing it indoors, Mr Wicks said – allowing it to dry completely first.

Shaking real trees thoroughly outside can help to remove loose pollen, dust and mould.

Meanwhile wiping down artificial trees and ornaments can get rid of some of the accumulated dust.

Reducing how long real trees stay indoors can help to limit mould levels, while storing fake trees and decorations in sealed containers can minimise dust accumulation.
