Why Do I Wake Up With Headaches After Sleeping?
Posted by Sleep Country Canada on Jul 22, 2026
Morning headaches can happen when something during sleep is putting stress on your body.
That might be:
- breathing disruptions during the night
- jaw clenching or teeth grinding
- poor sleep quality
- neck and shoulder tension
- alcohol or dehydration
- a mattress or pillow that isn’t supporting you properly
A lot of people assume it’s random. Often, it’s not.
