Waking Up With Headaches? The Common Nighttime Triggers to Check
In a recent reader’s question, we were asked, “Why do I keep waking up with headaches in the morning?”
You might be surprised, but morning headaches are common and are often a sign that something overnight is messing with your body’s reset cycle.
However, before digging into morning headaches, we should clarify the difference between a morning headache and a migraine.
According to the Cleveland Clinic, the type of head pain matters because morning headaches can show up as migraines, tension-type headaches, cluster headaches, or even in rarer patterns.
I’ve noticed people use the term migraine like it’s just a stronger headache, but that’s not the case. A migraine can come with nausea, dizziness, and sensitivity to light, sound, or smells, not just pain.
If you are certain it’s a morning headache and not a migraine, the first step is to review events from the day before.
Run the tape back on last night
The Sleep Foundation states that sleep loss, oversleeping, sleep posture, dehydration, teeth grinding, and alcohol use can all play a role in waking with a headache.
We recommend running through a quick checklist to gauge if anything obvious may have led to the headache:
- Alcohol: Even if you fall asleep fast, sleep can get disrupted, and alcohol-related dehydration can hit by morning.
- Water: Going hours without fluids adds up, especially if you snore or mouth-breathe while sleeping.
- Caffeine: Too much one day and then a sudden drop the next day can trigger a morning headache for some people.
- Pain meds: Using over-the-counter headache meds too often can cause headaches. Always read the side effects.
- Disturbed sleep: Having a poor night’s sleep can cause headaches in the morning.
Over the course of a few weeks, keep notes on the above. This will help you understand if your morning headaches are caused by changes in your day-to-day life.
The usual suspects behind morning headaches
As mentioned above, morning headaches are common, and the causes can be fairly standard. However, they can also be serious. The Cleveland Clinic highlights that sleep issues are often part of the puzzle. Issues can include insomnia, sleep apnea, and even teeth grinding.
Morning headaches can even be related to how you breathe through the night. Sleep apnea headaches are surprisingly common. If you find that the headache fades within about four hours of waking, with no medication, it may be related to apnea, and treatment should help.
Another top cause is sleep bruxism, which is the grinding or clenching of teeth while sleeping. This can lead to morning headaches, muscle pain, and tooth wear. If you have any of these, seek treatment.
Don’t rely on guesswork. If it’s frequent, track it for a couple of weeks and take your notes to your clinician. Let them help you figure out whether it’s sleep, hydration, migraine triggers, medication rebound, or something that needs further attention.
