The cracking of joints, especially knuckles, was long believed to lead to arthritis and other joint problems. However, this has been debunked . The cracking mechanism and the resulting sound is caused by dissolved gas (nitrogen gas) cavitation bubbles suddenly collapsing inside the joints. This happens when the joint cavity is stretched beyond ...
That creates space, which is then filled by the joints’ lubricative synovial fluid (made up of oxygen, nitrogen and carbon dioxide), adds Liza Egbogah BS.c., D.C., D.O.M.P., a posture expert ...

A common theme among these techniques is the use of a fine (10 0 –10 −3 Torr) or high (10 −3 –10 −6 Torr) vacuum to remove air, and the use of an inert gas: preferably argon, but often nitrogen. The two most common types of air-free technique involve the use of a glovebox and a Schlenk line, although some rigorous applications use a ...
Air is able to travel to the soft tissues of the neck from the mediastinum and the retroperitoneum (the space behind the abdominal cavity) because these areas are connected by fascial planes. [4] From the punctured lungs or airways, the air travels up the perivascular sheaths and into the mediastinum, from which it can enter the subcutaneous ...
There are benefits and risks to cracking your neck. Experts explain what you need to know about cracking your neck safely.
A US Air Force study reports that there are few occurrences between 5,500 m (18,000 ft) and 7,500 m (24,600 ft) and 87% of incidents occurred at or above 7,500 m (24,600 ft). [32] High-altitude parachutists may reduce the risk of altitude DCS if they flush nitrogen from the body by pre-breathing pure oxygen. [33]
