Do free divers get the bends?
Decompression sickness was originally thought to only occur in scuba diving and working in high-pressure environments. However, research shows that breath-hold diving (freediving) also poses its own risks for developing decompression sickness (DCS), also referred to as being bent or getting the bends.

The less severe type (or musculoskeletal form) of decompression sickness, often called the bends, typically causes pain. The pain usually occurs in the joints of the arms or legs, back, or muscles. Sometimes the location is hard to pinpoint.

What happens to your lungs when you free dive?
As we’ve seen, as you descend on a dive, the increased pressure causes the volume of air in your lungs to decrease. But as this happens, the partial pressure of the air inside your lungs increases. This means that there is a greater concentration of oxygen and other gases in our lungs than there is in the blood.
