30 Things That Could Be Causing Your Migraines
Too Much Sleep

On the other side of sleeping-related pain, sleeping too long or taking naps can also trigger migraines. Too much extra sleep affects the brain's neurotransmitters and serotonin levels. This can cause you to wake up at bad times, such as in the middle of a REM cycle, leading to migraines. Get a good, consistent sleeping schedule to prevent getting migraines associated with sleeping too much or too little.
