The Bends

The video tutorial explains hydrostatic pressure and its effects on divers, including how it increases with depth and can crush objects like a plastic bottle. Divers must equalize internal and external pressure to avoid injury. Rapid ascent can cause decompression sickness, known as the bends, due to nitrogen bubbles forming in the bloodstream. Atmospheric pressure also affects divers, and a further drop in pressure can be dangerous. Treatment involves using a recompression chamber to dissolve nitrogen bubbles safely.
