Every step, reach and bend depends on your joints. When they work well, we hardly notice them. When they ache, everyday activities become harder. Arthritis is one of the leading causes of disability: the CDC estimates that more than 1 in 5 US adults has been diagnosed with some form of arthritis. While some joint changes come with age, much of joint health is in our hands.

How Joints Work

A joint is where two bones meet. In mobile joints such as knees, hips and shoulders, bone ends are covered with smooth cartilage, which reduces friction and absorbs shock. The joint is enclosed in a capsule lined with a membrane that produces synovial fluid, a lubricant that also nourishes cartilage. Ligaments hold bones together, and muscles and tendons move them.

Cartilage has no direct blood supply. It relies on movement to circulate synovial fluid and bring in nutrients. That is one reason the phrase "motion is lotion" is popular with physiotherapists.

Common Joint Problems

Osteoarthritis (OA)

The most common form, involving gradual breakdown of cartilage and changes in the whole joint. It causes pain, stiffness (often brief in the morning) and reduced movement, especially in knees, hips, hands and the spine. Risk factors include age, previous injury, excess weight, genetics and repetitive strain.

Rheumatoid arthritis (RA)

An autoimmune disease in which the immune system attacks joint linings, causing swelling, warmth and prolonged morning stiffness, often in the same joints on both sides of the body. RA needs early medical treatment to prevent joint damage.

Gout

Caused by uric acid crystals, often causing sudden, intensely painful swelling, classically in the big toe.

Everyday stiffness

Long periods of sitting, inactivity and weak muscles commonly cause stiffness that improves with movement.

7 Habits for Healthier Joints

1. Keep moving

Regular low-impact activity such as walking, cycling, swimming, water aerobics and tai chi supports joint function and reduces pain in osteoarthritis. Major arthritis organisations recommend exercise as a first-line approach. See the benefits of walking.

2. Strengthen the muscles around joints

Strong thigh muscles (quadriceps), for example, take load off the knees. Strength training twice a week is recommended; read strength and balance for healthy aging.

3. Maintain a healthy weight

Every extra kilogram of body weight adds several kilograms of force on the knees with each step. Research has found that losing about 10 percent of body weight can significantly reduce knee pain in people with overweight and osteoarthritis. See healthy weight and metabolism.

4. Stretch and stay flexible

Gentle range-of-motion exercises and yoga help maintain flexibility.

5. Eat an anti-inflammatory diet

A Mediterranean-style diet rich in vegetables, fruit, oily fish, olive oil and nuts is associated with lower inflammation; see our anti-inflammatory eating guide. Omega-3s from fish have been studied for joint stiffness in rheumatoid arthritis; read omega-3 vs omega-6.

6. Protect bones and vitamin D

Strong bones and adequate vitamin D support the whole musculoskeletal system; see bone health awareness.

7. Use good body mechanics

Lift with your legs, avoid staying in one position too long, and set up your workstation ergonomically.

Comfort Measures for Stiff, Achy Joints

• Heat: warmth relaxes muscles and eases stiffness, especially in the morning. A warm shower or a herbal heat clay pack can help. See our moxibustion and heat therapy guide.
• Cold: helpful for swollen, hot joints after activity.
• Massage: gentle massage of surrounding muscles with a rich cream such as Comfort Cream with Emu Oil or Dr. Pine Recovery Body Cream can feel soothing.
• Supportive footwear and, where advised, braces or insoles.

What About Supplements?

• Glucosamine and chondroitin: results are mixed. The large US GAIT trial found no significant overall benefit compared with placebo, though some subgroups may respond.
• Fish oil: some evidence for reducing joint tenderness in rheumatoid arthritis.
• Turmeric/curcumin: some small trials suggest modest pain relief in osteoarthritis.
• Collagen peptides: early studies show mixed results.

Discuss supplements with your doctor, especially if you take blood thinners or other medications.

A 10-Minute Morning Joint Routine

1. Warm shower to loosen up.
2. Gentle neck rolls and shoulder circles (10 each).
3. Wrist and ankle circles (10 each direction).
4. Seated knee extensions (10 per leg).
5. Sit-to-stand from a chair (10 repetitions).
6. Gentle hip circles and a short walk around the house.

When to See a Doctor

• Joint pain with fever, redness or warmth
• Sudden, severe swelling
• Morning stiffness lasting more than 30 to 60 minutes
• Pain that interferes with sleep or daily activities
• Joint deformity or inability to bear weight

Early diagnosis matters, particularly for inflammatory arthritis and gout.

Frequently Asked Questions

Does cracking my knuckles cause arthritis?

Research, including a doctor who cracked the knuckles of only one hand for decades, has not found a link to arthritis.

Is running bad for my knees?

For most healthy people, recreational running is not linked to higher osteoarthritis risk and may even benefit joints. Build up gradually and wear suitable shoes.

The Takeaway

Joints thrive on movement, strong supporting muscles, a healthy weight and an anti-inflammatory lifestyle. Comfort measures such as heat and massage can ease everyday stiffness. Stay active, stay strong, and see a doctor when warning signs appear.
