Waking up with a headache: why does this happen so often?
September 28, 2016 8:54 PM   Subscribe

I get more than my share of headaches; I'm kind of prone to them. I get headaches maybe two or three times a week on average, and I've identified various headache triggers. And there is one clear tendency in my headaches: I'm much more likely to get them in the early morning (and wake up with them) than I am to get one at any other time of day. Why could this be?

Most of my headaches are mild, and the ones that I wake up with are short-lived; they usually dissipate within 15 to 90 minutes of waking up. It's hard to say when they start, since I'm asleep when they do, but based on the times that I have woken up during the night, the headaches seem to come in the hour or two before I wake up.

An obvious suspect is nighttime jaw-clenching/teeth-grinding. And the fact is that I do a lot of jaw-clenching and teeth-grinding when I sleep; I wear a mouthguard when I sleep because of it. But that is a most a co-culprit. Why do I think so? Because of the aforementioned headache triggers that I mentioned. Coming down with a cold or the flu is one. Eating too much of a salty snack is another. Being relatively dehydrated (and a related one: having a sweaty workout, and not obsessively replenishing my fluids enough afterword. By the way, I hydrate way more than the average person in general). Being caffeine-deprived. Eating certain foods that for some reason are problematic for me. All of these things greatly increase my chances of getting a headache, and I'm much more likely to get that headache in the early morning than at any other time, regardless of the timing of the headache-trigger activity.

I'm not going to give any other details about my health because I suspect that this is a universal tendency, not unique to me. That is, that there is something intrinsic to the human body (not just mine) that makes people in general more likely to get a headache in the early morning. Of course, most people get few headaches, so they wouldn't pick up on the tendency like I would. And I could be wrong. But that's why I'm here asking this: to understand my headaches better and try to find ways to get them less.

How is your pillow? If my head is at a weird angle I can wakes up with a headache.

Early morning headaches describe my sinus headaches and explain why they dissipate after 15 minutes plus.

As you note, dehydration and caffeine withdrawal are both very common and powerful headache triggers. They are also both very likely to be present immediately upon waking, since you haven't been able to drink anything, caffeinated or otherwise while you were sleeping.

All of my non-sickness-related early morning headaches seem to be due to dehydration (even though I too hydrate well during the day). I keep a 1L nalgene by my bed and when I wake up I chug from it, then flop back down onto my pillow going "ugggghhh" and feeling sorry for myself for about 5-10 minutes, and then I'm good to go.

Low blood sugar or high blood pressure can cause headaches on waking

If you have long hair, maybe change how you style it for sleep. I used to get headaches if I wore a high ponytail for too long.

Headaches in the morning can be a classic symptom of sleep apnea. Consider that all your headaches may not have common cause.

This is purely based on my own experience and guesses, not any medical knowledge, but my guess is dehydration is a significant factor, and I wonder if failing to breathe correctly while sleeping might also have an impact (I know that I snore). The headaches-upon-waking seem to be more common for me when I sleep for an especially long time, which is consistent with both of these theories.

I do not want to scare you, but I'm gonna say something kinda scary, because it's worth knowing.

Frequent headaches that are present as soon as you wake up and dissipate once you get out of bed and start to go about your day are a pretty classic brain tumor symptom. OBVIOUSLY THERE ARE LOTS OF OTHER POSSIBLE CAUSES TOO - sinus is very common, for one. But it may be worth mentioning to your doctor, especially if they become more frequent or seem to be getting more intense.

No one is answering your question, which is: is something intrinsic to the human body (not just mine) that makes people in general more likely to get a headache in the early morning?

And the answer is NO, there is no one thing that makes headaches happen in the morning or to any given person that could be said is universal enough to have one good piece of advice solicited over the internet that is a catch-all for eliminating headaches. but.....

Morning is a time of transition. You entire body goes from one state (sleep) into another state (wakefulness). Every system, circulatory, respiratory, endocrine, GI, changes during this transition.
Your brain, as it becomes active, demands more blood, blood which has pooled in your trunk while you've been prone.
Your muscles, as they begin to move, require blood as well. they are stiff from inactivity (or tired from hyperactivity if you've been clenching them)
Likely you are dehydrated, or hungry, or have gone a long time without caffeine or other meds.

Any or all of these factors can cause headaches, and there are a dozen more things i could list.
For that matter there are different kinds of headaches, and those have different causes as well.

My best advice is know your body. figure out what combination of normal things, like proper hydration, a good pillow, consistent bedtime, etc. give you good sleep and reduce your headaches. stick to those things. set yourself up for success. If you still suffer you might, then, want to see a sleep specialist, or talk to a physician about other underlying causes.

I get a right stonker of a headache if I sleep in too long, or oversleep. It doesn't happen as much now, my body clock seems to have got out of teenager mode as I've left my 20s and now I wake up with the lark even on mornings where I don't have anywhere to be. But certainly throughout my teenage years and 20s, if it was the weekend or a day off I would be routinely waking up at 10-11am with a stinking headache which would take most of the day and copious amounts of painkiller to get rid of. It was crap and nursing a headache was a waste of good time off.

There was never one cause of these headaches and I've managed to control them with a few different things - waking up early as a routine is one, but I've also recently started on blood pressure medication which has really helped - I used to get them at the end of particularly stressful periods, as if my body couldn't deal with coming down from the stress and anxiety. Optimising my life to minimise stress has also been an aid. Cutting down on caffeine in the day also helped to alleviate the headaches. I just have a cup of coffee first thing in the morning now, rather than drinking random cups through the day at work.

Basically, there are 101 things that could cause headaches first thing in the morning - I'm glad I'm now relatively free of the curse these days and I can enjoy my days off, but it took years of trial and error.

Seconding high blood pressure. Also, maybe dry eyes.

A new pillow fixed months of morning headaches for me. I recently switched to a down pillow for back sleepers and have been morning headache free for weeks now.

Low blood sugar and/or dehydration. I find a nice bug glass of fruit juice in the morning before I do anything else can really help. Also I have a history of sinus issues so shower in the morning so the stream can do its thing.

I'm a grinder too so I sympathize (I am terrible about wearing my night guard and I woke up with a headache today). Have you ever been to a chiropractor? A lot of the triggers you're describing relate to constriction - dehydration, lack of caffeine, all are vessel constriction and blood-supply related as OHenry said above.

One additional constricting cause/factor could be literal crimping of your blood supply caused by spinal misalignment. A lot of people are suspicious of chiropractic medicine (I go back and forth) but adjustments helped me greatly at certain times in my life with headache symptoms and other miseries. If you're finding that the headaches correlate to times when you are otherwise stressed out in your life, it might be a further indicator (stress-related muscle tension is often what leads to misalignment) that your spine is out of whack and that it's something physical/skeletal that is limiting your blood supply. A good old-fashioned back cracking can open up the pathways again. Always found yoga helpful too, not just for the mindfulness piece but for the physical alignment and flexibility part.

I realize I sound like a homeopath/hippie right now but I'm totally not. If there were some kind of laser robot technology I was aware of to relieve your symptoms I would be touting that, I promise. Good luck.

Do you wake up to an alarm, or naturally? Do you try to force yourself to sleep longer/less than you might naturally want to?

Waking up to an alarm sometimes gives me headaches, so I try to avoid it and allow myself to wake up naturally. Trying to force myself to sleep in almost always gives me headaches that naturally get better with time.

Dehydration and caffeine withdrawal both happen to me. I sometimes track how much I'm drinking (of both water and coffee) and my morning headaches and see where there is some correlation, and if so, increase water/cut back coffee, etc.

I often wake up with headaches, too. For me it's either a result of tooth clenching during the night or inflamed sinuses. My sinuses are inflamed by tooth clenching, allergies (esp. dust), dehydration, or sleeping slightly too long. I may also have nasal polyps but I'm too chicken to get it checked out at the moment. Anyway, I think you should see your doctor and get this figured out.

After my recent bout of headaches in the morning, my husband suspected cat fur so he stripped the bed and washed everything, including the top blankets which we kept forgetting about, and the cats' beds, and I picked up the habit again of using Flonase before I went to bed, and taking an Allegra at night. It worked. We're not 100% if it's the cats or seasonal allergies, but just "allergies" appears to be the answer.

I also wake up with them from dehydration, caffeine deprivation, and having a pillow that's too fat or too flat.

I agree with waffleriot that it's worth checking with a doctor on this. I also get morning headaches. For me, I'm pretty sure now it's from teeth-grinding. But many years ago, before I was even aware I ground my teeth in my sleep, I saw a neurologist about my headaches. I was not even concerned about the morning aspect; it was just the frequency that worried me. But as soon as she heard that these were morning headaches, she perked up and seemed concerned -- enough to arrange for me to get a head CT. The CT showed nothing to worry about, but I don't regret getting it, just to be sure.

I never did find out why she was so concerned. I was young at the time (in my 20s) and not inclined to ask questions of doctors the way I am now (in my 60s). And this was pre-internet, so I couldn't just google it. But I imagine that what waffleriot says is accurate.

Can't hurt to ask a doctor, right?

I had morning headaches for years, they would typically start, it seems, something in the week hours of the morning and would be full blown by the time I got up. I started talking about this to other people and discovered it was pretty common. And I did a lot of reading trying to figure out. One reason the headache may start then is that during the night is when the body has it's lowest amount of naturally-occurring opioids, and so any pain you may have is not being suppressed as well, and hence when you get up and start moving around, it tends to get better.

Do you drink? Try stopping completely. I was drinking 2 glasses of wine at dinner and once I quit, voila, the headaches completely disappeared, and they don't seem to come back if I have a couple of glasses every once in a while. It seems to be the regular consumption that was causing some kind of low-grade inflammation. If you do find drinking is a trigger, take a couple of ibuprofen before bed to decrease the inflammation.

Hydration. You mentioned that you drink more water than the average person, do track it and make sure that is true, there are lots of apps for that. And this is an interesting study that says that people who suffer from headaches need to drink much more than recommended amounts.

This is 20+ years old advice, but I was told that if you sleep with your head lower than the rest of your body (downhill), it can cause headaches cause all the blood drains down and pools in your brain. Probably not an issue in most modern day houses/beds, but...

Also, yeah, allergies. If you are the least bit prone, cleaning all the bedding, under the bed, the fans, the vents, etc, weekly or more can make a huge difference.
