A quirky Chinese trend shows seniors looping a U-shaped belt under their chins, clipping it to playground bars, and gently swinging to “cure” insomnia and neck pain. The idea came from 57-year-old Sun Rongchun of Shenyang, who says it eased his cervical spondylosis and who has now filed a patent and hosts group swing sessions.
Videos of the routine have spread across Chinese social media, but sleep specialists call it “a physics experiment on your spinal cord.” They warn the belt can pinch nerves, cut blood flow to the brain, fracture vertebrae, or even choke users; at least one death has been linked to a misplaced strap. Doctors urge people with sleep trouble to seek proven treatments and skip risky online fads.
