Night shift work and migraine: screens, sleep and light
Updated 2026-11-02
Quick answerA 2019 case series and review found the evidence on shift work and migraine sparse and conflicting, but sleep disruption is a known risk for migraine worsening. Two patients improved after moving back to day shifts. During night shifts, keep screens dim, take breaks and protect regular sleep where you can.

Not a medical device and not medical advice. Migraine Mode is a screen-comfort tool: it does not diagnose, treat, cure or prevent migraine or any other condition, and it does not replace a doctor. Its settings are based on studies of light, colour, flicker, patterns and motion; the extension itself has not been clinically tested. When to see a doctor.
