Inflammation and hormonal changes

Several types of arthritis, such as osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis, commonly flare at night. One reason is the body’s lower night-time cortisol levels. Cortisol is a natural anti-inflammatory hormone, so when levels dip, inflammation (and pain) may increase.

Cytokines, proteins involved in inflammation, can also rise during the night, contributing to swelling and pain around the joints.

Stiffness from staying still

Movement stimulates natural joint lubrication. When you sleep, and especially if you stay in one position for too long, your joints can stiffen, making pain feel worse.

Sleep problems can intensify pain

Poor sleep itself can increase your pain sensitivity by altering the nervous system and amplifying inflammatory responses. This two‑way relationship means pain disrupts sleep and poor sleep worsens pain.

Common Causes of Night-time Joint Pain

Sleeping position

Sleeping on your side may increase pressure on shoulders or hips, while sleeping on your stomach can place your neck in a strained position.

Unsupportive mattress or pillows

If your bedding doesn’t support proper spinal alignment, more weight and pressure may fall onto your joints, especially the hips, knees, and lower back.

Underlying health conditions

• Arthritis (including osteoarthritis and rheumatoid arthritis)
• Ankylosing spondylitis
• Old injuries or overuse

These conditions often create inflammation that peaks at night.

Stress and lifestyle factors

Stress can heighten muscle tension and inflammation and may prevent the body from properly winding down at night.

How to ease joint pain and improve your sleep

Heat or cold therapy

A warm bath or heated compress before bed can soothe stiff joints, while an ice pack may help where inflammation is prominent.

Optimise your sleep environment

• Keep your bedroom cool and dark.
• Consider upgrading your mattress or pillows to improve support.
• Use white noise if sound disturbances disrupt your sleep.

Try a pre-bedtime relaxation routine

Gentle stretching, meditation, or deep breathing can help your muscles relax and reduce stress hormones like cortisol.

Adjust your sleeping position

• Back sleeping with the right pillow can keep your neck neutral.
• Side sleepers may benefit from a pillow between the knees to maintain hip alignment.

Address sleep quality

As sleep deprivation increases pain sensitivity and inflammation, strategies such as consistent bedtimes and limiting screen exposure can be beneficial.

Physiotherapy and lifestyle management

Regular exercise, strengthening routines, and physiotherapy can improve joint stability and reduce stiffness - especially for arthritis-related pain.

When should you see a specialist?

Seek professional help if:

• Your joint pain is persistent or worsening
• Night-time pain is regularly waking you

Early assessment can help diagnose conditions like arthritis or injury-related issues and ensure the right treatment plan is in place.
