As families across the UK begin decking their homes for the festive season, a surprising concern has emerged: some Christmas decorations could be quietly disrupting our sleep. With searches for ‘bedroom Christmas décor’ rising by 195 per cent in recent weeks, experts are warning that adding festive touches to the bedroom may not be as harmless as it seems.
Dr Deborah Lee, health and sleep expert at Doctor Fox, working with Comfybedss, explains that while twinkling lights and garlands can feel cosy, they may interfere with the conditions we need for restful sleep. Decorations that emit strong light, dominate the room or create sensory overstimulation could have an impact on both sleep onset and sleep quality.
Dr Lee highlights five common Christmas décor choices that parents might want to rethink if they are hoping for peaceful nights this December.
First, she advises opting for warm, yellow-toned lighting rather than bright white LEDs. Cool, harsh light can mimic daylight and disrupt the body’s circadian rhythm, delaying the process of winding down at bedtime. Flashing lights pose a similar problem, as the constant visual stimulation can strain the eyes and keep the brain more alert.
Garlands and hanging decorations placed on bed frames or headboards can also undermine restful sleep. Dr Lee explains that having objects directly overhead can create a subtle sense of threat, even if we are not consciously aware of it, making it harder to fall into deep, restorative sleep.
She also recommends keeping bedroom decorations minimal. Large items such as full-sized Christmas trees can create a feeling of visual heaviness and become a distracting focal point in a space designed for calm. A small tree positioned away from the bed is a better option if you want festive cheer without compromising sleep.
Finally, Dr Lee warns against heavily scented festive room sprays and candles. Strong fragrances can reduce air quality and irritate the respiratory system, potentially contributing to headaches or restlessness. Light scents such as lavender remain the preferred choice for a sleep-friendly environment.
With many households preparing to decorate over the next few weeks, a few small choices could help ensure that Christmas spirit doesn’t come at the cost of a good night’s sleep.
