How Sleep Affects Migraines

The connection between rest and headache frequency.

The sleep-migraine connection

Research consistently shows that poor sleep is one of the strongest migraine triggers. Both too little and too much sleep can trigger attacks. The key is consistency. Tracking both reveals your personal threshold.

What to track

Log both Sleep and Headache data daily. Record:

Bedtime and wake time
Sleep quality rating
Number of interruptions
Headache occurrence, severity, and timing
Whether headaches follow short sleep nights

Patterns people discover

Most people who track both find that headaches cluster on days following less than 6 hours of sleep, or after irregular sleep schedules (like weekend sleep-ins). This gives you an actionable target: stabilize your sleep, reduce your migraines.
