Why Winter Flattens Your Mood (And What Light Does About It)
The problem
From November on, the alarm feels heavier. You're not depressed exactly — just flat, foggy until midday, and asleep on the sofa by nine. Coffee moves the needle for an hour, then drops you lower than before.
Why it keeps happening
Your circadian clock is set by bright light hitting the eye in the first hours of the day. Outdoor light on a grey morning is still 10,000 lux; a well-lit office is around 300. If you commute in the dark and work indoors, your body genuinely doesn't know the day started, so cortisol stays low and melatonin lingers.
The fix
A therapy light delivers the intensity a room can't. Twenty minutes in front of it while you drink coffee gives your brain the daylight signal it's missing, at the hour it matters most.
Twenty minutes, before 9am
Place it at eye level, roughly an arm's length away and slightly off-centre — you don't stare at it, you sit in it. Twenty minutes while you eat, read or answer email. Do it within an hour of waking, and stop by early afternoon so it doesn't push your bedtime later.
What to expect
Days one to three: easier mornings. Week two: the fog lifts earlier and your bedtime stabilises. Consistency beats duration — five short sessions a week outperform one long one.
