The short answer: lying still for hours can leave your body stiff, and your sleep position or mattress can add to it. Stiffness that eases soon after you start moving is less of a worry. Stiffness that lasts more than 30 minutes, comes with swelling or keeps going for more than a week is worth showing to your doctor.
Your first few steps of the day may not be your best. You shuffle to the bathroom. You take the stairs one at a time. By mid-morning you feel fine, and you wonder why you felt so stiff an hour ago.
There’s often a simple reason. The trick is knowing when there isn’t.
Why you wake up stiff
You’ve been still for hours. Cleveland Clinic says long periods without moving can cause stiffness and inflammation, and that moving stiff tissue in the morning can then be painful.
Your sleep position. Cleveland Clinic says sleeping on your stomach tends to throw your neck and spine out of line. Our guide on how to sleep with lower back pain shows where to put your pillows.
Your mattress or pillow. A soft, sagging or damaged mattress can pull your spine out of line, says Cleveland Clinic. Brown University Health says a mattress that’s too firm or too soft can also cause strain.
Arthritis. Brown University Health says that in people with arthritis, stiffness may come from less lubrication in the joints, or from worn cartilage. Morning stiffness can affect your back, fingers, wrists, knees, ankles or feet.
Another condition. Cleveland Clinic says spinal arthritis, fibromyalgia, disk problems and spinal stenosis can all add to morning back pain. Pregnancy can too.

The best clue: how long it lasts
Time it for a few mornings. Doctors use how long it lasts as a clue. These are clues, not a diagnosis.
| How long it lasts | What it may point to | Source |
|---|---|---|
| Under 15 minutes | The joint probably isn’t inflamed | MSD Manual |
| Up to 30 minutes | Typical of osteoarthritis, which usually wears off within 30 minutes of getting up | NHS |
| Longer than 30 minutes | May suggest something other than osteoarthritis, such as rheumatoid arthritis | NHS |
| Longer than 45 minutes | The main sign of polymyalgia rheumatica, a condition that causes muscle stiffness | NHS |
| An hour or longer | Typical of inflammatory arthritis, such as rheumatoid arthritis | MSD Manual |
The sources don’t draw exactly the same lines, so don’t treat these numbers as firm cut-offs.
The pattern matters too. The MSD Manual says stiffness that gets worse as the day goes on usually isn’t caused by inflammation.
Three conditions worth knowing
Rheumatoid arthritis. The NHS says stiffness is often worse in the morning or after you’ve been inactive. Getting diagnosed quickly matters, because early treatment can stop it getting worse and lower the risk of joint damage.
Polymyalgia rheumatica. This mainly affects older people, and it’s more common in women than men, says the NHS. Besides stiffness, it can cause severe tiredness, less appetite, weight loss and low mood. If you’re also exhausted all the time, read why you might always feel tired.
Ankylosing spondylitis. This affects the spine and usually starts between 18 and 40, says the NHS. The clue is that the pain gets better with exercise, but not with rest, and it’s worse in the morning and at night.
What helps you loosen up
These tips come from hospital health teams. They’re simple and low-risk, but we didn’t find good trials showing which works best. Try them and keep what helps.
- Move before you get up. Brown University Health suggests ankle circles and pumps, wrist circles, and knee and hip bends while you’re still in bed.
- Stretch your lower back. Cleveland Clinic suggests lying on your back, bringing one knee to your chest, holding for three seconds, then switching legs.
- Get up slowly. Sit on the edge of the bed for a moment, then stand using your legs, says Cleveland Clinic.
- Have a hot shower. The MSD Manual says this may relieve stiffness and make daily tasks easier.
- Stay active in the day. Brown University Health says to walk or stretch during the day, and to change position if you sit for long periods. See our exercises for lower back pain if your back is the stiff part.
- Look after your sleep. Brown University Health says the body repairs itself in deep sleep. Check that your mattress supports you.
- Time your medicine. If a doctor has prescribed medicine for arthritis, ask whether taking it before you get up would help. Brown University Health suggests 30 minutes to an hour beforehand.
When to get help
Get medical help right away if stiffness comes with a sudden new or frequent headache and a sore scalp, jaw or tongue pain when you eat or talk, or changes in your vision. The NHS says these can be signs of temporal arteritis, a condition linked to polymyalgia rheumatica that needs immediate care.
Get urgent help for sudden severe pain in one joint that’s hot, swollen or red, especially if you can’t move it or you have a high temperature. The NHS says this can be an infected joint.
Call emergency services or go to the emergency department if you have back pain with:
- Pain, tingling, weakness or numbness in both legs
- Loss of feeling around your genitals or bottom
- Changes in your bladder or bowels, such as trouble peeing or losing control of pee or poo
See your doctor if:
- You’ve had pain and stiffness for more than a week (NHS)
- Morning muscle or joint pain lasts more than an hour (Brown University Health)
- Your back is so stiff it’s hard to take a deep breath (Brown University Health)
- You have ongoing numbness or tingling in your arms or legs along with joint pain (Brown University Health)
- You have morning back pain most mornings for two or three months, or it’s getting worse (Cleveland Clinic)
Your next step
For the next three mornings, note the time you get up and the time the stiffness fades. Write down where you feel it too. It takes seconds, and it’s useful to bring to your doctor if you need to go.

Quick questions
Is it normal to be stiff in the morning?
Some stiffness after hours of lying still is common. Cleveland Clinic says long periods without moving can cause stiffness. If it lasts more than 30 minutes or keeps going for more than a week, talk to your doctor.
How long should morning stiffness last?
The NHS says morning stiffness from osteoarthritis usually wears off within 30 minutes of getting up. The MSD Manual says stiffness from inflammatory arthritis typically takes an hour or longer to ease.
Is morning stiffness a sign of arthritis?
It can be, but not always. The NHS says rheumatoid arthritis stiffness often lasts longer than osteoarthritis stiffness. Only a doctor can tell you the cause.
What helps morning stiffness quickly?
Gentle movement in bed, getting up slowly and a hot shower are simple things to try. The MSD Manual says stretching and a hot shower may relieve stiffness.
Can a mattress make me stiff in the morning?
It can add to it. Cleveland Clinic says a soft, sagging or damaged mattress can pull your spine out of line, and Brown University Health says one that’s too firm can also cause strain.
