You wake up, try to turn your head towards the alarm clock and... locked. A sharp pain on one side of the neck, and to look to the right you have to turn your whole torso like a robot. It is one of the most common reasons people contact us.
The reassurance comes straight away, and it is true: it is almost always a benign problem that resolves. What follows is less comfortable to say, and we say it anyway. Much of the advice you will find everywhere about stiff neck, heat rather than ice, exact healing times, exercise dosages, does not come from studies done on stiff neck. It comes from research on other neck pain, often in people with whiplash or chronic pain, and from clinical experience. These are reasonable indications, not proven certainties. Knowing which is which changes how you use them, and stops you expecting from a heat pad what a heat pad cannot do.
⚠ Important: read this first before going on
The exercises and advice in this article are general guidance and may not suit your situation. Everyone has a unique clinical history: what works for others could be counterproductive for you.
Want a professional's opinion? Start with the questionnaire: you register and see who will follow you, a physiotherapist on the official register chosen for your case, whom you write to in chat. If you would rather hear their voice first, the first consultation is free and we look at your situation together.
First of all: when a locked neck is not a stiff neck
This part should be read before the exercises, not after. A stiff, painful neck is almost always a simple stiff neck, but it is also how some conditions that cannot wait present. Go to a doctor or the emergency department, without trying any manoeuvres or stretches, if neck pain comes with:
- fever and general malaise, or stiffness so severe that you cannot bring your chin towards your chest;
- a recent trauma (accident, fall, blow to the head). In that case the picture is different, and you will find our guide to whiplash useful;
- persistent tingling, loss of strength or pain running down the arm;
- a sudden, violent headache, significant dizziness, problems with vision, speech or balance, or an eyelid or pupil different from the other side;
- constant night pain that does not change with position, particularly after the age of 50 or with a cancer history.
The fourth point deserves an extra line. Dissection of the cervical arteries, carotid or vertebral, is a significant cause of ischaemic stroke in young adults and can start with symptoms that seem trivial: headache, neck pain, dizziness. It is rare, but it is exactly why a locked neck with neurological symptoms should not be treated as an ordinary stiff neck.
What happens in the neck (and what we do not know)
In older children, torticollis has different causes from those in adults and should be looked at differently: torticollis in the older child.
The classic explanation is this: a sudden movement, a night with the neck twisted, a draught felt, or simply weeks of accumulated tension, and the muscles contract to protect the area. It hurts a lot, but there is rarely structural damage. It is more like an overly sensitive burglar alarm than a broken door.
It should be said honestly that this is a clinical description, not a verifiable diagnosis. There is no test that proves the spasm in an individual case, and the orthopaedic physiotherapy guidelines on neck pain published by the orthopaedic section of the American physical therapy association, in the 2017 revision, are indeed built on the functional limitations described by the WHO's ICF classification, not on precise anatomical diagnoses. In practice this matters little, because the initial management does not change. It matters for another reason: if the mechanism is a protective response and not an injury, the goal is not to "repair" something, but to gradually convince the muscles that they can let go.
One distinction is worth making, because the same word covers two different things: the torticollis of the newborn is not this. There, the neck muscle has been shortened since birth, the head stays tilted always to the same side, and what is watched is how head control progresses, step by step in the first months. If what you have noticed is simply a head always turned to the same side, before calling it torticollis it is worth understanding whether the neck can reach the other side or not: the difference between preference and limitation is covered in what to look for in a newborn who always turns the head to one side. And if the baby was born breech, neck and hips are looked at together, because they often share the same origin: the months spent squeezed into the same position: what to check in the first months after a breech birth.
"Cure or make a stiff neck go in 10 seconds": why that promise is false
It is one of the most searched questions, so we will answer directly: in ten seconds a stiff neck does not get better. No manoeuvre, no miraculous pressure, no instant "unlock" cancels an episode in progress with a single gesture. Anyone who promises you that is selling you something.
There are, however, things that give quick relief, which is a different category from healing: heat that eases the vice-like feeling, small repeated movements that within a few minutes restore a few degrees, correcting the positions that re-trigger the pain every hour. Relief, yes; cure in ten seconds, no. The difference is practical, not philosophical: those chasing an instant unlock often end up having their neck twisted by unqualified hands.
The "draught" and air conditioning: what lies underneath
It is the explanation almost everyone gives, and it deserves a precise answer rather than a shrug.
What we know: no study has measured air conditioning as a cause of stiff neck. On the climate in general, the 2024 meta-analysis of case-crossover studies found no association between temperature, humidity or pressure and musculoskeletal pain. Room temperature, as a variable, does not hold up.
What is different: a direct jet on one precise point is not room temperature. A vent blowing on the neck for hours, on sweaty skin, or an open car window on the motorway, are localised and prolonged cooling of one area, more similar to working in a cold environment, where an association with neck and shoulder pain has been observed, than to a winter day. It remains a reasonable hypothesis, not a proven link.
And what is almost always underneath: the neck locks after hours in the same position. In summer you spend those hours in an air-conditioned office, and the air conditioner is what stays in your mind. If covering your neck makes you feel better, do it: it costs nothing and does no harm. But the part that really changes the timing is in the paragraph below: moving early.
Heat or ice? The honest answer
The standard remedy for stiff neck is "heat, not ice", and we ourselves recommend it. But for stiff neck, or even just for the neck, no studies have compared the two. The only solid synthesis available concerns the lower back: a Cochrane review that included nine studies and 1,117 participants in total. Be careful about which part of that total supports the conclusion: the result on heat wraps comes from just two studies with 258 participants, with moderate-quality evidence of a small reduction in pain at five days in a mixed population of acute and subacute pain, and the comparison was with an oral placebo, not with cold. For cold the evidence is insufficient to say anything, and on any difference between heat and cold the results conflict. A single study of 100 participants, again on the back, found that adding exercise to heat reduced pain at seven days more than heat alone. The authors themselves open their conclusions by saying that the evidence base supporting such a widespread practice is limited.
Transferring these results from the back to the neck is an extrapolation, and it should be called that. The correct way to use the information: heat is cheap, pleasant and carries almost no risk, so it is worth trying, a hot water bottle, a warm shower or a heat pad for a quarter of an hour, several times a day. If it makes you feel better, use it. If you prefer cold and cold makes you feel better, the evidence does not contradict you. What you should not do is wait for heat to resolve the stiff neck: in the best data we have, and on another part of the body, heat alone does less than heat combined with movement.
Stiff neck: what to do, in order
If you arrived here with a locked neck this morning and want to know what to do now, the order is this, and each point is explained further down.
- Rule out the things that are not a stiff neck (the section above): if there is fever, a trauma, weakness in one arm or a headache you have never had, see a doctor and do not do any exercises.
- Do not immobilise the neck. This is the point where the evidence is strongest, and it is the paragraph below.
- Heat, if it gives you relief, to make movement bearable, not as a cure.
- Move the neck within the limits where it does not hurt, little and often, with the progression in the "Exercises" section.
- Count days, not hours: how long it really lasts comes later, and anyone promising ten seconds is selling something.
Moving early: here the evidence really is there
This is the point where the evidence is most convincing, and it is worth looking at closely because it comes from a related but not identical context.
A randomised study published in the BMJ in 1989 followed 247 people who arrived at the emergency department within 48 hours of a neck sprain after a car accident, assigned to physiotherapy, to advice on early mobilisation, or to an initial period of rest. At two years 167 participants out of 247 answered the questionnaire, and it is on the respondents in each group, not on the 247 enrolled and not on the 167 pooled together, that the percentages should be read: symptoms still present in 11 people out of 48 (23%) among those who had been advised to move early, against 12 out of 26 (46%) in the rest group and 24 out of 54 (44%) in the physiotherapy group, with the difference in favour of early mobilisation statistically significant (p = 0.02). These are small numbers, and it is worth knowing that. In the same study, limited to those who had received the advice or the physiotherapy, people with no symptoms had worn the collar for a significantly shorter time than those with persistent symptoms (in the advice group, 1.4 months against 2.8).
A second randomised study, of 201 people with a neck sprain after a car accident, compared, over the first 14 days, the invitation to continue normal activities with the alternative of resting from work plus a soft collar. At six months the "carry on as usual" group was doing better on several subjective symptoms, including neck stiffness and pain intensity. Be careful to read it for what it is: the comparison is not "movement against nothing", it is movement against rest and immobilisation.
Neither study concerns stiff neck from a pillow or a draught. They are traumas. But they are the best evidence we have for the general principle, and they all point in the same direction: after acute neck pain, getting back to moving early beats passive waiting.
An important point: before trying these exercises, make sure you have received a correct diagnosis. People often assume they have one problem when the real cause of the pain is something else. Doing the wrong exercises can make things worse instead of better.
Exercises for stiff neck: a reasonable progression
First a clarification that almost nobody makes. The Cochrane review of exercises for mechanical neck disorders, updated in 2016, found moderate-quality evidence in favour of programmes of strengthening and stretching of the neck, shoulder and scapulothoracic region, with a long-term reduction in pain quantified as a standardised mean difference of -0.45 (95% confidence interval -0.72 to -0.18), but in populations with chronic neck pain, not in acute episodes. The same authors conclude that the optimal dosage still needs to be studied.
This means two things. First: the numbers that follow (repetitions, sets, seconds) are a starting point used in clinical practice, not a validated dosage; adjust them according to your response, without treating them as a prescription. Second: the rule that matters more than any count is to stay below the threshold of strong pain. Tolerable discomfort that does not worsen in the following hours is fine; a stab that makes you stiffen means you are going too fast.
Phase 1: the first days, to get movement back
- Gentle rotations. Sitting, slowly turn the head towards the free side and then towards the painful side, as far as you can go without a stab. About ten repetitions per side, repeated several times during the day. The good sign is gaining a few degrees with each set.
- Side bends. Bring the ear towards the shoulder, slowly, without forcing the last part. Same volume as the rotations.
- Chin tuck. Slide the chin backwards, as if making a double chin, holding for a couple of seconds. It helps bring the head back over the trunk after hours spent jutting it forward.
Phase 2: when movement starts to come back
- The same three movements, but at the end of the range gently assist with a light push of the hand to gain a few degrees, holding the position for about ten seconds.
- Stretch of the upper trapezius and levator scapulae. Tilt the head to the opposite side and rotate the gaze towards the armpit, with the shoulder on the stretched side kept low. Half a minute at a time, a couple of repetitions per side.
Phase 3: when the pain has almost gone
- Isometrics. Hand on your forehead, push the head against the hand without any movement, for a few seconds; then repeat with the hand on one temple and then the other. This is the phase closest to what the Cochrane review actually tested, namely strengthening, with the difference, which it is right to declare, that in the trials the programmes were guided by a physiotherapist and not self-directed isometrics. It is still the part that makes sense to maintain over time, not only during the episode.
- Add a short daily mobility routine, especially if you work at a computer: you will find a complete routine of exercises for cervical pain already organised.
If the neck is so stiff that Phase 1 is out of reach, we have a dedicated guide on how to unlock the neck safely.
How long a stiff neck lasts
Here the honest answer is uncomfortable: no study establishes a precise duration for common stiff neck. The figures that circulate, two days, three days, a week, are estimates from clinical experience dressed up as data. Our experience is that most of the pain eases within a few days and full mobility generally returns within one or two weeks, with more intense episodes possibly taking a few days longer; but that is experience, not measurement.
The real numbers we have concern different populations, and it is worth knowing them anyway. In the BMJ study on neck sprains, of the 104 people found to be symptom-free at two years, 90% had recovered within six months and 60% within three. These are long timescales compared with a stiff neck from a pillow, and they concern a trauma: they serve as a reminder that the neck, when it is seriously upset, does not work on a scale of days.
The practical indication we take from this is less a number than a direction: what counts is the trajectory, not the intensity today. If each day you turn your head a little more than the day before, you are on the right track even if it still hurts. If after two weeks the situation is identical to the first day, it is no longer a matter of patience and it is time for an assessment.
How to treat a stiff neck in 10 seconds
You cannot, and anyone who tells you otherwise is selling something. It is worth saying clearly, because it is one of the most frequent searches of all: in ten seconds you cure nothing, neither a stiff neck nor anything else.
What you can do in a few seconds is lower the guard of the muscle, and that is not nothing: a slow, long breath with the shoulders letting go, warmth resting on the trapezius, the head supported rather than held up by the muscles. These things reduce the defensive contraction within a few minutes and make movement possible, and movement is the real remedy.
The difference lies entirely there: ten seconds serve to stop making it worse, the hours and days that follow are what resolve it. And the thing that really shortens the timing is not a trick, it is moving the neck within what you can tolerate, early and often, as described above.
The mistakes that prolong it
The homemade collar. The tight scarf or the collar bought at the pharmacy and worn for days is the most common mistake. In the BMJ study, the collar worn for longer was associated with persistent symptoms, and the authors put this in their conclusions. In the second study the collar was not isolated: it was part of a package that also included resting from work, so from there you cannot infer how much the collar alone matters. The collar has precise indications and a doctor decides them, not the drawer at home.
Total immobility. Staying still waiting for the stiff neck to pass by itself is the collar-free version of the same mistake. Everything we know about acute neck pain says the opposite: you get back to moving early, little and often, within the range the pain allows.
Having your neck manipulated by someone unqualified. A point needs correcting here that is often read, including in earlier versions of this article: it is not proven that cervical manipulation "worsens the spasm". A systematic review with meta-analysis of 14 randomised trials found no significant differences in the frequency of adverse events between high-velocity, low-amplitude cervical manipulation, the classic "snap" manoeuvre, and control interventions, and all the events reported were mild. The authors add the decisive caveat, however: randomised studies are not the right tool for detecting rare, serious events. The reason we advise against being "unlocked" by improvised hands is therefore not a quantified risk: it is that nobody will have assessed your neck and the warning signs in the list at the start beforehand.
Treating recurrences as bad luck. If it is the third stiff neck in six months, that is not chance: it is a pattern, and it needs looking at where the pattern is generated.
If it keeps coming back, the lever is not the neck exercise
This is the part that is usually left out, because it spoils the ending. The best-evidence synthesis carried out by the international Task Force on neck pain, 226 articles examined and 70 accepted after critical review, found that between half and three quarters of people with neck pain in the general population still report it one to five years later. Neck pain, in other words, tends to come back.
In the same synthesis, and here is the part that is less welcome, general physical exercise was not associated with a better outcome, while the strongest predictors were psychosocial factors: psychological health, the coping strategies used to deal with pain and the need for social contact. In the same synthesis, younger age predicted a better outcome. This is not an invitation to stop moving: the Cochrane review of exercises shows that specific strengthening of the neck and shoulder girdle works on chronic pain. It is an invitation not to expect that ten minutes of mobility in the morning will cancel out an unsustainable workload, five-hour nights and a level of stress that never comes down. If your stiff neck returns at a regular rhythm, look there too, and if you want to explore that side, we discuss it in neck pain from stress.
The honest way to use this guide
Summing up without embellishment: common stiff neck is almost always benign and improves; the first thing to do is not an exercise but to rule out the signs listed at the start; heat is a good low-risk palliative but has not been shown to be superior to cold, and on the neck it has not even been studied; moving early is the advice with the best support, even though it is derived from cervical trauma; strengthening has solid evidence, but on chronic pain and with a dosage still to be defined; the precise durations you read around do not exist in the literature.
Put like this it sounds like little. In fact it is more than you need to manage the next few days well: warm it, move it, do not immobilise it, do not let the first person who comes along twist your neck, and judge by progress rather than pain. If the trajectory does not improve, or if the episodes keep recurring, that is where an outside eye really shortens the road.
