Why Joints Get Stiff: Common Causes of Joint Stiffness and How to Ease It

What is happening inside your joints, and what helps.

Quick answer

Joint stiffness is a feeling of tightness or reduced range of motion, often worst in the morning or after sitting still. It is common with age because cartilage gradually thins and holds less water, joint fluid can become less effective at lubricating, and the ligaments and tendons around joints lose some elasticity. Inactivity, past injuries, extra body weight, cold weather and repetitive strain can all add to it. Gentle movement, warming up, staying active, maintaining a healthy weight and a nutrient-rich diet usually help. Stiffness lasting more than an hour each morning, or joints that are swollen, red or warm, should be checked by a doctor.

Key takeaways

That creaky, tight feeling when you get out of bed or stand up after a film is one of the most common complaints after 40. Here is why it happens.

Common causes of joint stiffness

Age-related changes

Cartilage gradually thins and holds less water, so it cushions less effectively, and connective tissue becomes less elastic.

Inactivity

Joint fluid circulates when you move. After long periods of rest, joints feel “gelled” until you get going.

Wear and tear

Years of use, past injuries, repetitive work and sport all place stress on joints.

Body weight

Every extra pound adds load to weight-bearing joints such as the knees and hips.

Everyday ways to ease stiffness

Start the day with gentle range-of-motion movements, take breaks from sitting every 30 to 60 minutes, choose low-impact activities like walking, cycling and swimming, apply warmth to stiff joints, keep a healthy weight and eat plenty of vegetables, fruit, oily fish and whole grains. Some people also choose a joint supplement; Feilaira combines glucosamine, chondroitin, Boswellia, turmeric, MSM and bromelain to support joint comfort and flexibility.

See a doctor if morning stiffness lasts more than an hour, if joints are swollen, red or warm, if you have a fever, if stiffness follows an injury, or if it is getting worse.

Common questions

Why are my joints stiff in the morning?

Joint fluid circulates less during rest, so joints often feel tight until you start moving.

Does joint stiffness get worse with age?

It often does, because cartilage thins and connective tissue loses elasticity.

What helps stiff joints?

Gentle movement, regular low-impact exercise, warmth and a healthy weight.
