Zero gravity sleep position may ease back pain and improve circulation

The "zero gravity" sleep position, elevating the head and legs, is trending online for potentially easing back pain, reducing snoring, and improving circulation. This position, similar to astronauts during liftoff, spreads body weight, significantly reducing spinal pressure and aiding circulation by helping the heart pump blood. While beneficial for many, especially those with back issues or reflux, it's not a universal solution and individuals with certain medical conditions should consult a doctor.
