Morning Stiffness: Causes and What It Means

Why joints are stiff in the morning

During sleep, joints are still for hours. Fluid can collect in and around inflamed joints, and the lining (synovium) swells. Movement pumps that fluid away and warms the tissues, so stiffness eases. In inflammatory conditions, the body's natural anti-inflammatory hormone cortisol is lowest overnight, while inflammatory chemicals peak in the early morning. This is why inflammatory stiffness is longer and worse.

Duration is the key clue

Causes of morning stiffness

Osteoarthritis

The most common cause in people over 50. Cartilage wears and the bone underneath changes. Stiffness usually lasts a few minutes to half an hour. See osteoarthritis.

Rheumatoid arthritis

An autoimmune disease that inflames the joint lining. Typical features are morning stiffness of an hour or more, swollen and tender small joints of the hands and feet on both sides, and tiredness. Early treatment within the first few months protects joints from permanent damage. See rheumatoid arthritis.

Polymyalgia rheumatica

Affects people over 50, mostly over 70. Pain and stiffness in both shoulders and hips, and often the neck, come on over days to weeks. Getting out of bed, dressing and lifting your arms become hard. Stiffness lasts more than 45 minutes. It responds dramatically to low-dose steroids. About 1 in 5 people with it also develop giant cell arteritis. See polymyalgia rheumatica.

Ankylosing spondylitis and axial spondyloarthritis

Inflammatory back pain starting before age 45, lasting over 3 months, with low back and buttock stiffness that is worst in the morning, improves with exercise but not rest, and may wake you in the early hours. See ankylosing spondylitis.

Psoriatic arthritis

Joint inflammation in people with psoriasis, sometimes before the skin rash. It can cause a whole swollen "sausage" finger or toe, nail pitting and heel pain.

Other causes

• Lupus: joint pain and stiffness with rash, mouth ulcers, tiredness and sensitivity to the sun. See lupus.
• Fibromyalgia: widespread pain, stiffness, unrefreshing sleep and fatigue. Joints are not swollen.
• Hypothyroidism: muscle aches, stiffness and tiredness.
• Gout and pseudogout: attacks of a hot, swollen joint.
• Viral arthritis: after parvovirus, hepatitis or chikungunya, usually settling within weeks.
• Plantar fasciitis: heel pain with the first steps in the morning.
• Parkinson's disease: stiffness (rigidity) and slowness that is often worse before morning medicine.
• Lifestyle: an unsupportive mattress, awkward sleeping position, dehydration, inactivity and heavy exercise the day before.
• Medicines: statins can cause muscle aches and stiffness.

How doctors find the cause

A doctor will ask how long stiffness lasts, which joints, whether they swell, and about skin rashes, eye inflammation, bowel symptoms, family history and general health. They examine joints for swelling, warmth and range of movement. Tests may include:

• Blood tests: CRP and ESR (inflammation), rheumatoid factor and anti-CCP antibodies, ANA for lupus, HLA-B27 for spondyloarthritis, thyroid function, uric acid, creatine kinase
• X-rays: joint damage and osteoarthritis
• Ultrasound or MRI: detect early inflammation (synovitis) and sacroiliac joint inflammation

Relief from morning stiffness

• Move gently before getting up: stretch, bend and straighten your fingers, knees and ankles in bed.
• Warmth: a warm shower or bath, or a heating pad, loosens joints. Warm water hand exercises help stiff fingers.
• Stay active during the day: regular exercise such as walking, swimming, cycling and yoga reduces stiffness over time.
• Sleep well: a supportive mattress and pillow, and keeping joints warm overnight.
• Time your medicine: some people take anti-inflammatory medicine or slow-release steroids timed to work by morning, under medical advice.
• Over-the-counter pain relief: acetaminophen (paracetamol) or NSAIDs such as ibuprofen can help. Follow the label dose, and check with a doctor if you have kidney, stomach or heart problems.
• Weight management: reduces load on knees and hips.

For inflammatory arthritis, disease-modifying medicines (such as methotrexate) and biologic drugs control the underlying inflammation and greatly reduce morning stiffness.

Frequently asked questions

What causes morning stiffness?

Morning stiffness is caused by fluid and inflammation building up in joints during hours of rest. Short-lived stiffness is usually from osteoarthritis or muscle tightness. Long-lasting stiffness of more than an hour suggests inflammatory conditions such as rheumatoid arthritis, polymyalgia rheumatica or ankylosing spondylitis.

How long does morning stiffness last in rheumatoid arthritis?

In active rheumatoid arthritis, morning stiffness typically lasts at least an hour and can last several hours. Its length is a useful measure of disease activity, and it shortens as treatment controls the inflammation.

Is morning stiffness normal as you get older?

Some brief stiffness, lasting a few minutes, is common with age and mild osteoarthritis. Stiffness lasting more than 30 to 60 minutes, or with swollen joints, is not a normal part of aging and should be checked.

Why am I stiff all over in the morning?

Whole-body stiffness can come from polymyalgia rheumatica (in people over 50), fibromyalgia, an underactive thyroid, viral illness, poor sleep or a hard workout the day before. If it lasts more than a few weeks or limits your movement, see a doctor.

Does exercise help morning stiffness?

Yes. Regular movement keeps joints lubricated and muscles flexible. Gentle stretching in the morning and regular low-impact exercise reduce stiffness over time, especially in osteoarthritis and ankylosing spondylitis.
