The habit of cracking your knuckles is extremely dangerous.

If you crack your joints frequently, the bone structure will automatically adapt, and the joint membrane and surrounding ligaments will stretch, leading to problems such as wear and tear, degeneration, and inflammation of the articular cartilage.

Cracking knuckles and toes is a habit for many people when they feel tired, numb, or stiff in their fingers or toes, or after doing something for a long time. Cracking joints makes us feel more comfortable and relaxed, but this practice can have negative effects on our health.

Cracking our joints might make us feel better, but it can have negative effects on our health.

Arthritis

Each joint is composed of two articular surfaces, covered by a joint capsule and a system of ligaments that function to bind and stabilize the joints. When cracking your knuckles, unlike normal flexible stretching, the joints are stretched suddenly, producing a clicking sound. If the stretching exceeds its limit, the joint capsule is subjected to a significant impact, making the ligaments prone to stretching and tearing.

Joint surface wear

If you crack your knuckles for a long time, the increased friction and pressure on the joint surfaces cause wear and tear, and more seriously, increase the risk of degeneration and inflammation of the articular cartilage. Each time you crack or manipulate a joint, it causes micro-trauma to the joint, and consequently, the cartilage cells are also subjected to micro-trauma. If these micro-traumas accumulate in the same joint over time, it will lead to cartilage depletion.

Each time a joint is manipulated, it causes micro-trauma to the joint.

Effects in old age

Hand injuries from the habit of cracking knuckles are almost unavoidable. Maintaining this habit for a long time can easily lead to joint pain in old age.

Articular cartilage consists of 2% chondrocytes (cartilage cells) and has no ability to regenerate when injured. Manipulating or cracking joints will wear down and damage the cartilage, leading to degeneration.

Once cartilage is worn away, it cannot regenerate, and bone spurs will grow, affecting the surrounding tissues of the joint and causing swelling and pain in the fingers. As people age, tendons, cartilage, and ligaments become less flexible and more susceptible to injury, so twisting and bending the joints will accelerate the rate of joint degeneration.

Advice

After each twist or crack, we may feel more comfortable, but it's best not to crack your fingers, toes, or twist your cervical spine because these actions can harm the cartilage or discs, damaging the joints.

Whenever you feel tired, simply move the joint gently back and forth to its maximum range of motion without causing pain or crackling sounds. This simple movement will help increase blood flow to the tissues, providing relief while preventing joint stiffness and avoiding micro-injuries.
