For many of us, autumn's arrival means more than just donning our coziest jumpers and cranking up the central heating. As the days shorten and mornings grow darker, energy levels plummet and a heavy sadness settles in – a condition known as seasonal affective disorder (Sad).
This isn't new. In fact, ancient Chinese texts like the Yellow Emperor's Classic of Medicine have long noted how the seasons can impact our mood. The advice from over 2,000 years ago? "Retire early and get up with the sunrise", keeping one's desires and mental activity quiet and subdued.
Fast forward to today, when scientists are once again shedding light on the biology behind seasonal affective disorder. Research has shown that people's moods do indeed follow a predictable pattern – rising in autumn or winter and dropping in spring. Symptoms include excessive sleepiness, lethargy, and cravings for carbohydrates.
So what's behind this phenomenon? The answer lies in our internal body clock, regulated by light exposure. Without sufficient daylight – especially when combined with artificial light pollution at night – our circadian rhythms can go haywire. And that's not all: a study published last year found fluctuations in the expression of over 4,000 genes in white blood cells and fat across the year.
Researchers are now studying how people with bipolar disorder respond to light cues, too. Dr Cathy Wyse at the University of Edinburgh notes that these individuals may be highly sensitive to seasonal changes and light exposure – triggering their symptoms.
While bright light therapy remains the gold standard for treating Sad, cognitive behavioural therapy can also be just as effective in reframing one's relationship with winter rather than simply managing symptoms.
So what can we do to beat the winter blues? Try this: get outside first thing in the morning, even on grey days. Daylight resets your clock, improves alertness and keeps melatonin at bay. Light therapy lamps – emitting around 10,000 lux – can also be a game-changer. Stick to regular sleep schedules, avoid screens before bed and keep evening lighting warm. And plan some winter pleasures: cosy rituals like hot chocolate or candlelit baths might just be the pick-me-up you need.
Ultimately, the most effective antidote to Sad remains natural sunlight – so make the most of any sunshine that comes your way.
