Can Less Sunlight Affect Migraines?

It may—especially when shorter days change your body's natural rhythm.

Sunlight reaching your eyes helps regulate your circadian rhythm, your internal body clock. Changes in light exposure can influence melatonin, a hormone involved in sleep timing, and are also connected with regulation of serotonin, a neurotransmitter involved in mood and many other brain functions.

This matters because sleep and migraine are closely connected. The American Migraine Foundation notes that shorter days can change your sleep schedule, and an inconsistent sleep cycle can trigger migraine.

So the connection may look like:

Less daylight → changes in your body clock → changes in sleep and biological signals → possible migraine trigger

This doesn't mean that less sunlight directly causes migraines, and more research is needed to determine exactly how seasonal light changes affect individual people with migraine.

If you notice more migraines during darker months, try keeping your sleep and wake times consistent and tracking your daylight exposure, sleep, and migraine days.

For additional comfort during a migraine, Soothie Hoodie can be used as a complementary wellness option. Its hot/cold gel packs and gentle pressure around the head and upper neck may provide a soothing sensation.
