The Bottom Line
- Stop trying to ‘study like a normal person’ on abnormal hours—anchor your physiology first.
- Use light, caffeine, and meals as levers; use revision as a *small* consistent output.
- Your goal is discrimination + maintenance, not heroic coverage.
Shiftwork reality check
If your sleep is collapsing, studying harder is usually the wrong move. Protecting sleep (even imperfectly) is the fastest way back to performance.
Shiftwork scrambles attention, working memory, and mood. The highest ROI move is not a new resource—it’s a repeatable set of circadian anchors that stabilise you enough to do consistent, small revision. This page gives you a system that works even with ugly rotas.
1
Choose your anchor sleep (non-negotiable)
Pick a realistic daily block (even 4–6 hours) you protect most days. Everything else (naps, revision, meals) orbits this.
2
Use light like a drug
Bright light at the start of the shift to increase alertness; dim light and screen filters towards the end; sunglasses on the commute home if you’re trying to sleep.
3
Front-load caffeine; don’t drip-feed it
Caffeine works best as a planned tool. Use it early and deliberately; avoid continuous ‘sipping’ that sabotages recovery sleep.
4
Meals: prioritise stability over perfection
Aim for protein + fibre early in the shift. Keep the final meal lighter if you need sleep immediately after work. Big heavy meals + late caffeine is the classic trap.
5
Revision: set a ‘minimum viable’ output
Pick one tiny daily deliverable: e.g., 10 timed questions OR 15 flashcards OR 1-page ‘error log’ update. Consistency beats ambition.
