Snap💥Crackle💥Pop💥
Oh the sweet sound of tension release. What actually happens when you crack your joints? Is it safe to DIY?
TLDR: ✅It’s generally safe if not forceful. ❌Avoid if habitual or repetitive (wear & tear). If accompanied with adverse effects (pain, numbness, bruising, paralysis, etc) - see a professional.
The cracking sound comes from two typical reasons: rubbing between two structures (bone on bone, tendon on bone, etc) and releasing of gas from joint spaces. Other reasons are also possible (eg, actually snapping of bone/tendon/ligament 😳).
If you find sweet relief from cracking your back, knees, neck, knuckles, ankles, etc with natural and gentle movement, it is likely from the releasing of gas from these stiff joints - which leads to more joint movement and less discomfort. Some people find even just the sound oddly satisfying 👀
When does safety become a concern?
❌There is associated pain, numbness, discomfort, paralysis, etc. In this case, please see a professional! There can be swelling or irritation on or close to a nerve or vessel. Continuing to crack can lead to further damage.
❌It is forceful. Cracking by gently turning your body in the morning is generally safe. Whipping your body with uncontrolled overpressure is not. This can indicate that soft tissues around the joint need to be addressed before the pop can naturally come with a gentle stretch as opposed to uncontrollably whipping it. Leave the big ones to the professionals 👍
❌It is repetitive. In this case, the snapping or cracking sound may be from two structures rubbing poorly against each other - this is typical in the knees, shoulder, and hands as there are many thick tendons around those joints. These situations may cause wear and tear over time. If you hear a click every time you do a shoulder raise - try a different exercise or consult a professional.
❌When it is habitual. Eg, cracking you knuckles. We get it, it is satisfying, addicting, and tension releasing. But over time, it leads to damage and instability to the joint structure. The good news is that you can overcome this habit! Try spacing out your need to pop to once a day, 2 days, 1 week, etc.
