Put up that tree now, your mental health will thank you

Psychologists explain that decorating early triggers a surge of dopamine, the brain’s “feel-good” chemical, which can lift mood and reduce stress. Taking your time to string lights or hang ornaments also avoids the last-minute scramble, letting people enjoy the season without pressure.

Nostalgia is another powerful factor. Digging out childhood ornaments or revisiting family traditions sparks positive memories, creating a sense of warmth and connection. Psychologists say these moments of reflection can improve emotional well-being and even counter feelings of seasonal stress or sadness.

Decorated homes also send social signals. Research shows festive displays make houses appear more welcoming and sociable, encouraging community connection. The act of decorating itself aligns with behavioural activation, a principle in cognitive behavioural therapy: even if you don’t feel joyful at first, engaging in cheerful activities can actually boost mood.

Lights also play a practical role in combating winter gloom. Twinkling decorations brighten spaces during the darker months, helping buffer against seasonal blues. Even simple visual cues like a lit tree or wreath can trigger feelings of comfort and joy.

Of course, early decorating isn’t for everyone. For those with difficult holiday memories, the experience may not provide the same emotional boost. But for most, starting the season early can stretch out joy, foster connection, and give the mind a subtle but meaningful lift.

So, this year, if the urge to untangle last year’s fairy lights hits before December, science says: go ahead. You’re not just getting festive, you’re giving your mood a holiday gift, too.
