Light Management
The cornerstone of SAD prevention.
Morning — within 30 minutes of waking:
- Use a 10,000 lux SAD lamp (e.g. Lumie Halo, Beurer TL 50, Circadian Optics). Sit 45-60cm away, facing indirectly, for 20-30 minutes while working, journaling, or eating breakfast.
- Open blinds immediately on waking, even if it's dark or cloudy — natural light still helps anchor your circadian rhythm.
- If you can, get outside for 10-15 minutes before 10am, ideally walking.
Evening:
- Dim lights after 8pm.
- Avoid overhead lighting — switch to lamps, amber bulbs, or candles.
- Optional: blue-light blocking glasses — not mandatory, just helpful if on screens.
Supplement Stack — UK Winter
- Vitamin D3 + K2: 4,000-5,000 IU daily, morning, with fats. Most UK adults are deficient Nov-April.
- Omega-3 (EPA dominant): 2-3g combined EPA/DHA daily.
- Magnesium glycinate or threonate: 200-400mg in the evening.
- B-Complex (especially B6, B12, folate): once daily in the morning — supports serotonin and energy metabolism.
- Optional: L-Tyrosine (500-1000mg AM) for dopamine support; Ashwagandha (500mg PM) if stress/anxiety rise; Creatine (5g/day) — shown to improve mood and energy in low-light conditions.
Behavioural & Routine Strategies
Move daily. Even 30-45 minutes of moderate training keeps serotonin and dopamine elevated. Don't chase PRs if motivation dips — prioritise frequency over intensity.
Keep sleep timing consistent. Bedtime and wake time within 30 minutes daily. Avoid sleeping in excessively on dark mornings — it worsens circadian misalignment.
Warm mornings. Use a heated blanket or a hot shower + caffeine ritual to anchor motivation on dark days.
Maintain social connection. Winter isolation amplifies SAD — book classes, open mats, or small group sessions ahead of time. Build non-negotiable weekly anchors.
Environment & Habit Tweaks
- Keep your living space bright — LED daylight bulbs in main rooms.
- Use hygge cues: warm lighting, clean spaces, plants, scents.
- Sauna or hot/cold contrast 2-3x/week if available — boosts dopamine, mood, circulation.
- Keep a "winter wins" journal — record small daily gratitudes or accomplishments.
Mindset & Reflection
- Acknowledge that energy is cyclical — don't attach self-worth to productivity dips.
- Use winter for deep work, planning, reflection, and building foundations.
- Practice morning light exposure and evening wind-down rituals religiously. Consistency beats motivation.
