A military sleep technique has gone viral on TikTok and claims to help people fall asleep in just two minutes. Developed for fighter pilots, the hack involves relaxing specific muscle groups and focusing on breathing. Users are then instructed to imagine a calm scene, such as lying in a canoe on a calm lake or in a dark room on a black velvet hammock. The technique, featured in the book "Relax and Win: Championship Performance," was reportedly successful for 96% of pilots, even with distractions like gunfire.
