Is pain & stiffness your alarm clock? Do you bail out of bed early every morning with low back pain, neck pain & more?
“I woke up with it” is an amazingly common description of how low back pain started. (And neck pain and headaches. And even more.1). Is sleeping dangerous? Probably not: waking up with back pain rarely indicates a serious problem. Both mornings and backs are unusually vulnerable to some common minor sources of pain.
This article is mostly about chronic back pain that’s at its worst in the morning, a common pattern. Even many people who are more or less pain-free during the day may still experience routine and significant irritation and stiffness first thing in the morning. But attacks of acute back pain are also much more common in the first few hours of the day,2 and that phenomenon may be related to why chronic back pain tends to be bad in the morning.
Morning back pain is a tough problem to treat because most of it probably has several subtle chronic causes, but there may be some opportunities for treatment in changing the way we sleep.
What causes flare ups of back pain in the morning?
Lita Scruton of Ontario asked me for an explanation of her morning back pain:
Every morning I awaken stiff and have to get out of bed. No sleeping past 7am for me, ever! I can’t take the discomfort. So why during the day I can do anything, even exercise, and have no discomfort? Why do my muscles get so painful while I am suppose to be relaxed and resting? If I awaken during the night to use the bathroom they feel great, but any time after 6am, it is a whole different story. Can you help me solve this mystery?
There are four main explanations for morning back pain:
- Inflammatory back pain: pathological inflammation from autoimmune disease, which is often serious, relatively rare, and fairly well known.
- “Inflammaging”: slow but steady increase in chronic mild inflammation as we age.
- Myofascial pain syndrome and/or fibromyalgia: probably extremely common, but more mysterious and controversial.
- Awkward sleeping postures: although this is the most “obvious” reason for waking up with a kink in your back, it might be worse than you expect.
Inflammatory back pain is the scary one
The closest thing to back pain that truly “likes” the morning is inflammatory back pain (IBP), or spondyloarthritis.3 Although IBP is well known to medical science, it often eludes diagnosis, its biology is mostly mysterious, and morning symptoms specifically are a stumper, just as unexplained as joints that ache before a storm. It’s just something IBP does.
But don’t panic! Although studies have confirmed that morning is a common time for inflammatory back pain to flare up, they have also shown that the connection is not strong or exclusive.4 In fact, most morning stiffness and pain is not pathologically inflammatory. It’s just that IBP is the only “official” morning back pain culprit.
The pain of IBP tends to be quite severe. If it’s not actually waking you up, it’s probably not IBP, or it’s a minor case.
Nastier and unusually consistent morning symptoms are good cause to consider the possibility of IBP. The diagnosis is also more likely if you have other signs of this kind of back pain. Here’s a good inflammatory back pain quiz, and here’s my own quick checklist of reasons to ask your doctor about spondyloarthritis:5
- signs of inflammation in other body parts, especially tendons (where they attach to bone), eyes, fingers or toes, colon
- a family history of spondyloarthritis (although it develops slowly, it’s a serious disease, so you’ll definitely know if someone in your family had it), or other autoimmmune diseases
- you respond fairly well to NSAIDs (Aspirin, Ibuprofen, etc)
- an infection in the weeks before your back trouble began
Technically IBP causes night back pain, not morning back pain
The morning pain of IBP is actually a case of leftover nighttime symptoms, which wear off as you wake up and get moving. When the symptoms are milder, you will mostly sleep through them, noticing them only when you wake up. But these symptoms will usually be obvious while you are still in bed, as soon as you are conscious — or even waking you up early.
In contrast, pain that you don’t notice until you actually get up and start trying to move around is less likely to be inflammatory in nature. But these are rules of thumb only, of course — there’s always lots of exceptions in biology.
Doctors, do not actually trying giving this advice with patients! Joke by 9GAG (with about a bazillion likes & shares on Facebook).
Myofascial pain syndrome and/or fibromyalgia
There are two common causes for widespread moderate body pain, both somewhat mysterious and controversial, both known for affecting the back more than other areas, and both known for their morning hijinks:
- Myofascial pain syndrome (MPS) is an infestation of too many “trigger points” — sore, aching patches of soft tissue that often seem to ease with massage and heat, but which are mostly unexplained and difficult to treat.
- Fibromyalgia (FM), a disease of increased sensitivity generally and decreased pain threshold, fatigue and sleep disturbance, and the “fibro fog” (mental confusion).
There’s likely lots of overlap between these conditions. While FM is more clearly a neurological dysfunction, and MPS is hypothetically a problem with muscle tissue, they seem to cause many of the same symptoms, and each condition probably aggravates the other.
Fibromyalgia is associated with morning back pain because:
- People with FM rarely feel rested. The condition either causes or is caused by fragmented sleep and a lack of deep restorative sleep. Fatigue makes any pain worse, and this is probably felt mostly acutely in the morning, gradually (and imperfectly) yielding to the stimulations of the day: exercise, sunlight, coffee, people, noise and so on. The morning-ness of fibromyalgia pain could also just be “one of those things,” an unexplained rhythm of the disease.
- Although FM causes widespread pain by definition, back pain is particularly common.
And trigger points may be associated with morning back pain because:
- Tissue stagnancy and postural stress seem to be a major cause of flare ups of trigger point pain, and both are an issue at night: we are often pretzeled into awkward positions in our sleep for long periods.
- The paraspinal muscles seem to be particularly vulnerable to trigger points.
The tendency of FM and MPS to affect the back in particular might be because they each affect it in their own special nasty way, or it could be two sides of the same coin. Perhaps fibromyalgia affects the back more than other areas because it causes vulnerability to trigger point … which occur in the back muscles much more than other muscles.6
Fibromyalgia and MPS both exist on a wide spectrum of severity. Fibromyalgia’s diagnostic criteria are notoriously tricky.8 MPS is barely even recognized as a clinical entity. Many people may have mild cases that will never be diagnosed, but morning back pain may be the tip of that iceberg — the most likely time and place for the symptoms to be felt, even if you are otherwise mostly fine.
What do you do about trigger points and fibromyalgia?
Those are both big, separate topics, but there are many resources on PainScience.com where you can get started. Self-massage and heating are by far the best (cheap, safe) ways to start working on muscle knots. Fibromyalgia is much more complicated, but the basics are sleep improvements, lots of light but thorough exercise, and learning about sensitization and the weirdness of pain.
Chronic low-grade inflammation and “inflammaging”
Everyone over 40 knows that it gets more uncomfortable to get out of bed as we age. Most people chalk it up to “arthritis,” but that’s rarely a significant factor until much later in life. Conditions like fibromyalgia and myofascial pain syndrome, as common as they are, can’t account for all of it. So what’s the problem?
A little bit of inflammation spread all over the place is a likely culprit. This might happen as a consequence of “metabolic syndrome,” [NIH] a set of biological dysfunctions strongly linked to poor fitness, obesity, and aging, and possibly linked to severe chronic stress as well.9
And aging itself seems to be inflammatory (no matter how fit, skinny, and calm you are), which is known as “inflammaging.”10 So, if you’re on the far side of middle age, or you’re younger but struggling with your weight and/or major long-term stress, chronic inflammation could be your issue.
Connecting inflammaging to the curse of morning back pain
This is an interesting topic, but does it have anything to do with morning pain or back pain specifically?
The morning connection isn’t much of a reach: for whatever reason, inflammatory diseases are notoriously morning-o-centric (like inflammatory back pain mentioned above), and so it’s reasonable to assume that less serious inflammation has a thing for the morning too. We also know — only just recently — that the body can suppress inflammation at night, pumping out an anti-inflammatory protein on a schedule,11 which probably accounts for some morning pain and stiffness as the suppression wears off. No one knows anything about how to actually control that effect, but at least we know it exists.
The back connection is trickier. Being overweight is less of a risk factor for back pain than most people think,12 so there’s no obvious association with metabolic syndrome. If there is a connection, it might be that the spinal joints are among the first structures to be affected by inflammation — and not necessarily because they are more fragile or harder working than, say, knees, but perhaps because the brain is quite over-protective about the back, and more likely to raise the alarm sooner.13 Also, we do know that metabolic syndrome is associated with at least some common pain problems, like neck pain,14
It could also just be simple overlap: maybe it’s just that these problems often just all happen at once. Inflammaging gets to everyone sooner or later, and back pain is spectacularly common, so they probably co-exist in the same people whether they have anything to do with each other or not.
What can you do about inflammation and inflammaging?
No one really knows, but here are some sensible ideas …
- Fitness is critical — it’s the closest thing we have to a miracle drug or a fountain of youth. But also avoid overdoing it.
- It’s also possible to some extent to eat an “anti-inflammatory” diet — which really just means a healthy diet, particularly one that doesn’t give our system major blood sugar regulation challenges.
- Fasting and ketogenic diets may also be worth experimenting with.
- Working on anxiety and major sources of chronic stress (like insomnia) is important too.
- And of course you should consider quitting any habits that are putting a strain on your biology, like smoking (of course), or drinking too much too regularly (more than a couple per day).
Osteomalacia (Vitamin D deficiency)
Vitamin D deficiency is probably more common than once suspected — at least 1 in 20 people in the lowest estimates,15 and possibly many more.16 Vitamin D deficiency can cause subtle widespread pain that may be misdiagnosed as fibromyalgia and/or chronic fatigue syndrome. Most notably for the purposes of this article, it can cause bone aching, particularly in the back, that is worse at night (for no clear reason). Naturally, any night pain that doesn’t actually wake you up is often noticed upon waking.
This symptom is caused by osteomalacia, which is bone weakening from malfunctioning bone building biology. The Mayo Clinic describes osteomalacia symptoms like so: “The dull, aching pain associated with osteomalacia most commonly affects the lower back, pelvis, hips, legs and ribs. The pain may be worse at night, or when you’re putting weight on affected bones.”
Other symptoms of vitamin D deficiency include: fatigue and weakness, lower pain threshold, and more acute soreness after exercise that is slower to resolve, sweating, and depression. For more information, see Vitamin D for Pain.
Nighttime tissue stagnancy and awkward postures
In 2015, Steffens et al discovered that most “back attacks” — episodes of acute back pain — occur in the first few hours of the day.17 They also identified an “awkward posture” in the two hours preceeding the attack as the second biggest risk factor (after “distracted during an activity”). Although their study wasn’t perfect, the results were too strong not to take seriously. Notably, “awkward posture” was quite a bit more likely to be associated with acute back pain than much more traditional bogeymen like heavy lifting, even difficult or obviously poor lifting.
Based on this evidence alone, we can guess that maybe one reason morning back pain — both acute and chronic — is so common is that sleeping is a great source of awkward back postures. And, in people with chronic back pain, it may be a routine source of minor irritation of their ongoing problems.
Being still is always inherently uncomfortable. We like to move, and sitting or lying down always gets uncomfortable in time. Forced immobilization is a potent torture method. Working in stagnant postures — like sitting in at a desk, no matter how well we do it — can start to feel more like a kind of torture as we age.18
Sleeping is another obvious source of tissue stagnancy, of course, but beds are more comfortable than chairs in every way, physically and psychologically. Healthy young people are relatively immune to this. But as we age and develop assorted vulnerabilities and sensitivities — things like fibromyalgia, myofascial pain syndrome, and chronic inflammation — it starts to become a problem.
Trigger points in particular may be aggravated by stillness.19 Morning pain could be a wake-up call (ha ha), letting you know that you have a bumper crop of mostly asymptomatic (“latent”) trigger points that flare up overnight. In Lita’s case, trigger points could account for the consistency of her symptom timing, and for the peculiar way in which she is fine at 6am, yet can’t stay in bed past 7am, but then is fine again by 8am as she gets moving and her trigger points calm down.
Stillness alone will eventually start to hurt, no matter how comfortable you are, but what if you’re uncomfortable to begin with? What if you’re not just still for a long time, but in a really awkward position? Awkward positions can be quite painful, even injurious. Sleeping often involves slightly awkward positions held for periods long enough to cause sustained compression, pinching, and oxygen starvation of tissues (which may or may not have already been vulnerable or irritated).
The dose makes the poison: it doesn’t have to be an obviously bad posture to cause trouble. Just a little awkwardness will do the job if you’re stuck that way for long enough. Although people can also carelessly tolerate postural stresses while wide awake, it’s much more of a risk at night.
Minor injury (or re-injury)
We may also cause minor injuries in our sleep, or aggravate existing minor injuries and vulnerabilities (like chronic minor back pain). Sometimes you just roll over and pinch something hard enough and quickly enough to hurt it — maybe not even enough to wake you up, but enough to feel the consequences when you do wake up. Usually this is going to be an isolated incident, but what if you keep pissing off the same vulnerable tissue?
For instance, suppose you already have minor intermittent back pain related to an old accident: it’s bothered you for years, off and on, and you’ve learned that leaning backwards is usually bad news. But then you do it in the middle of the night in your sleep, an extended lumbar spine for an hour when you weren’t even conscious — no fair! And so you wake up in moderate pain.
In other words, whatever is bothering your back in the first place can be easily and routinely aggravated — re-injured — by common sleeping positions.
I have no personal experience with back pain like this, but I know exactly what this is like from trying to sleep with a shoulder injury.20
Such incidents won’t explain all chronic, consistent morning back pain, because you’re unlikely to slightly but frequently re-injure yourself in the same way. Or maybe it’s not so unlikely: if bending your spine one way or the other is a problem, it might be easily avoided during the day, but happen to some degree most nights. Again, it’s the duration that’s the issue.
Is there such a thing as “bad posture” when sleeping?
If you know that a sleeping position is uncomfortable for you, but you keep sleeping like that, that’s bad sleeping posture. 😉
Sleeping position is clearly a factor in some back pain. Just about the only study ever done on this topic showed a small improvement in a few back pain patients who were “instructed regarding the recommended way to sleep” — which basically meant a more neutral position.21 The benefit was real but small. I think position is a minor factor in low back pain, and tough to fix unless there’s an obvious terrible position to avoid. Usually we don’t even suspect a problem with our sleep posture until it’s too late! For most people, trying to work on sleeping position probably does not offer particularly good bang for buck.
The most likely position to cause trouble is face down. I do not think that sleeping face down is a universally evil sleeping position — I am not on that bandwagon. But, based on years of anecdotal reports from clients and readers, I do think face-down sleeping does tend to bug lots of backs.
We can do a little to minimize the chances of an awkward position, mainly by starting out as comfortably as we can, and adding a little bracing with pillows to discourage too much rolling around. Using a knee pillow is the best example of this: just put an extra pillow between your knees while lying on your side. This reduces rotation in the spine, and rolling face down. Unfortunately, most people who toss and turn can make short work of any pillow arrangement in their sleep. Any pillow that’s in my way is kicked off the bed in about five minutes.
Mattress and pillow changes and upgrades
There world is full of claims about better mattresses and pillows, and you can even find the extreme opinion that we should get rid of them entirely and sleep on the ground, “naturally” — paleo sleeping!22 But even the tamest of these claims are wishful thinking. Comfort is a critical factor, and there are so many subjective variables in what constitutes “comfortable” that it is impossible to objectively define the “best” mattress or pillow. Oddly, it’s also actually impossible to really know our own preferences! We really can’t know how comfortable a mattress is without sleeping on it for a couple weeks. We’d have to buy a series of mattresses and take some really careful notes on sleep quality, and even that would be a flawed method. Testing pillows is more feasible, but not much.23
There is a bit of evidence that a new mattress can improve back pain.24 A small study found that back pain was worse for people with the cheapest and oldest mattresses, and improved when they got better new mattresses. The difference was not dramatic, but worth noting, and undoubtedly worthwhile. If insomnia or the sleep disturbances of fibromyalgia are part of your problem, it’s probably a good idea to optimize anything you can.
The anti-nap: take a sleep break
Here’s one weird, good trick: if you’re really struggling with night and morning pain, break up the night. Just like you need breaks from long stretches of sitting, you may need to take a break from sleeping.
If you’re actually sleepless and in pain, don’t stay in bed squirming in misery all night — get up and help yourself! Or if you are sleeping, set an alarm! Either way, get out of bed, and mobilizations, heating, or self-massage your back — or whatever else you’ve ever found helpful. Or ignore your back and do something pleasant.
If you were in an awkward position when the alarm went off, you may really be doing yourself a favour by interrupting it. You can “reset” your sleeping position when you go back to bed.
Few people have ever thought of trying this, let alone taken it seriously, or tried it consistently for a few nights. There’s an understandable emotional reluctance to interrupting sleep for the sake of doing therapy on yourself — we’re all over-tired, and that’s an issue too — but it may well be the lesser of evils, if sleeping is hurting your back.
Stranger still, it may even be unhealthy (as well as painful) to try to sleep all the way through every night. There is actually a natural wakeful period in the middle of the night, like a mirror image of afternoon naps, which most modern people are resisting — we think we’re supposed to be asleep all night!25 But that natural tendency to wake up for a bit may actually exist to prevent excessive tissue stagnancy! So try not fighting it for a while — you don’t have to do it every night, or forever. If it helps you get through a rough patch with your back, it’s certainly worth a shot. And it’s worthwhile if it helps you sleep when you go back to bed!
Final tip: try getting up and taking care of your back for a few minutes without turning on a light — staying in the dark will help preserve “sleep mode.”
Probably not. The book Back Sense proposes that morning back pain is caused by “stressful night-time mental patterns manifesting as back pain.” I do not dismiss the role of psychology in back pain — quite the opposite! it’s a major theme in my writing about back pain.
But I think that author is indulging in a simplistic mind-body connection theory. I’ve written crankily about this kind of logic elsewhere (see Why Do We Get Sick? or Pain is Weird). It’s a bit of a reach to say that you have such a problematic, pain-causing mental state like clockwork every morning between 6am and 7am exclusively. Applying How to Simplify Chronic Pain Puzzles to the problem, it is much (much!) more likely that there is simply a time limit on how long you can lie in bed without tissue crankiness.
What about nocturnal intervertebral disc swelling?
This is one of the classic theories about why people seem to be more vulnerable to back pain in the morning.
Between every pair of vertebrae is a bit of padding, the infamous disc. They probably swell up a wee bit overnight. There are two studies that suggest this2627 (although one of them was a study of long term bed rest, and only barely applicable here). A 2016 paper speculates that disc swelling is why astronauts probably suffer from more disc herniations than they should.28 Weightlessness is undoubtedly like resting your spine, but it’s another long-term effect, so I’m not sure how relevant the astronaut angle is — it’s just a fun angle on the topic.
I saved this idea for last because it’s too speculative to be really satisfying.
Discs may swell, but that doesn’t mean swelling discs hurt. Mild swelling is hardly a concern in itself, and most people don’t wake up in pain, so it’s unlikely that swelling alone is a problem. Swollen discs may hurt more in the morning if there’s already something wrong with them, such as annular tears,29 but such discs might well be uncomfortable regardless. Mildly herniated discs might swell and effectively be more herniated in the morning — but many herniations are painless, so that’s hardly a smoking gun.
It’s an interesting possibility that nocturnal disc swelling is a factor in morning back pain, but the truth is beyond our reach. For all we know, problems with discs might be much more aggravated by postural stress … or it could be a complicated combination, such as swelling that is exaggerated by postural stress but still only hurting when other problems are present.
Morning baths are almost miraculous for some kinds of morning back pain
A hot bath is one of the oldest medicines. While most people appreciate a nice hot bath, few people think of it as a serious treatment for back pain — just something that takes the edge off. Maybe.
But for morning back pain, it can be incredibly effective. Reader C.B. writes:
I am 73 with assorted age-related issues, but this low back pain every morning is new. Here is what I do: I run a hot bath, and jump in and immediately the pain goes away, all of it. Why would that be, and what does it mean?
C. is not alone: many people report near rapid, profound relief from morning back pain. Baths seem to be at their best in this context, and it’s not clear why. When a bath has an immediate, profound effect on pain, it’s probably because immersion/floatation is a fairly potent dose of “novel sensory input,” which can very persuasively tell the brain that there’s no need for the alarm of pain. This may be more pronounced with some kinds of pain that are aggravated by gravity, so the partial floatation might be directly relieving.
And then, by the time you get out of the bath, the relatively transient phenomenon of morning back pain is already retreating … and perhaps even faster because of some thermal effects (getting the blood flowing, etc).
But all that’s speculation. No one really knows! It’s not always super convenient to take a bath in the morning, but if you suffer from stubborn morning back pain, it’s worth a try at least some of the time. I’d like to hear more about this from readers: please let me know if hot baths do or don’t help your morning back pain. Believe or not, I actually have an entire, surprisingly large article about bathing tips. See: Hot Baths for Injury & Pain: Tips for getting the most benefit from a hot soak, the oldest form of therapy.

- Morning pain and stiffness is a symptom of several common conditions, including fibromyalgia, osteoarthritis, rheumatoid arthritis, plantar fasciitis, Achillis tendinitis, and carpal tunnel syndrome.

This study of triggers for episodes of back pain concluded that the "brief exposure to a range of physical and psychosocial factors," mainly being distracted during an activity and awkward postures, can "considerably increase the risk of an episode of acute back pain." But much more so in the morning:
Mornings were the most frequent time of day for back pain onset, with 35.2% of participants (n=352) reporting pain onset between 7:00 AM and 10:00 AM (Figure 2). Only 3.7% of participants (n=37) reported pain onset between mid- night and 5:00 AM, with a large increase in reports from 6:00 AM.

For instance, several other pain problems were also more likely: “migraine headaches, fibromyalgia, abdominal pain, and chronic widespread pain.” Weight is associated with more pain in general, not low back pain specifically, as you’d expect if the problem were simply due to compression of the spine. Clearly that typical assumption is not a safe one, and indeed the apparent connection between weight and pain weakened when the data were adjusted for common denominators like depression, a strongly confirmed risk factor for low back pain. In other words, if you factored out the depressed cases, the remaining subjects were not all that likely to have back pain. Given such complexity, the researchers made it clear that more and different research is needed to figure out what, exactly, is causing what. No kidding!BACK TO TEXT

- There is a distinction between “discomfort” and having significant back pain. Sitting a lot at work is not linked to back pain (see Lis, Bakker, Chen). The discomfort we feel when we sit too still for too long time does not seem to be a risk factor for serious episodes of back pain. BACK TO TEXT
- There’s no direct evidence for this. It’s a claim that has often been made my clinicians and experts on the topic. Although no one knows exactly what makes trigger points flare up (or go away), extremes of activity and stimulation — too much and too little — are plausible possibilities that seem to be consistent with what patients often report.

- I ripped up my shoulder joint playing ultimate (a Frisbee sport). It was hard to sleep for most of a year. When I did sleep, I routinely rolled onto the injured shoulder. Sometimes it woke me up; if it didn’t, I’d wake up with my shoulder howling. And then it would calm down and be mostly fine for the rest of the day. I knew exactly why I had morning shoulder pain, but what if my shoulder was vulnerable for some less obvious reason? I might have thought I had unexplained “morning shoulder pain.” BACK TO TEXT

Could “paleo sleeping” help aches and pains? This short, bizarre old paper in the British Medical Journal offers some interesting raw data about “instinctive” sleeping postures in primates. Unfortunately, the author’s interpretation is so grandiose and silly that I have to mostly just roll my eyes at it. From the introduction:
You probably do not know that nature has provided an automatic manipulator to correct most spinal and peripheral joint lesions in primates. In common with millions of other so called civilised people you suffer unnecessarily from musculoskeletal problems and are discouraged about how to treat the exponential rise in low back pain throughout the developed world.
That’s mighty big talk! All you have to do is sleep on the ground, and all your body pain will be solved! Sheesh.
The whole thing is a classic example of wishful thinking based on romanticizing “primitive” and “natural” lifestyles. Specifically, I think the premise that primitive people have fewer musculoskeletal complaints at all — let alone that it’s due to sleeping postures — is undoubtedly the product of confirmation bias and not remotely reliable. It could be true, but it probably isn’t. It’s much more likely that it’s just what western observers see because it’s they want to believe. The extremely poor reasoning on display in this article does no favours to the hypothesis.
And, oh dear, there are way too many references for “correcting” joints! What does that even mean? The absurdity peaked for me with this statement:
The Achilles tendon of the leading foot can be inserted in the gap between the big toe and the first lesser toe to help correct a bunion.
What utter bollocks! This is the hubris of structuralism at its worst.BACK TO TEXT
- A few years ago, I got keen on trying to figure out “once and for all” what kind of sheets I really like. I bought several sets of sheets of different kinds and qualities, including some expensive ones. Despite the expense and the effort, the experiment was a failure: I wasn’t organized enough, and simply couldn’t keep track of the relatively subtle differences between sheets. But I did at least learn that I have no obvious preference for premium sheets. 😉 BACK TO TEXT

We often worry about lying awake in the middle of the night — but it could be good for you. A growing body of evidence from both science and history suggests that the eight-hour sleep may be unnatural.
Indeed, all the research indicates that humans aren’t actually built to sleep through the night (with the exception of my wife, apparently, who can sleep 10 hours without so much as rolling over). The wakeful patch tends to occur between about 2–4. I discuss this more in my insomnia tutorial.BACK TO TEXT
