Want to prevent snoring? Answer is at your feet

    Researchers have found a simple solution to a rather embarrassing problem —  snoring. And the answer to that is simply to wear flight socks.

    Flight socks or compression tights are stockings that help prevent deep vein thrombosis (DVT) or varicose veins by applying light pressure around the ankle to help blood flow. While its effectiveness in preventing DVT is debatable, the stockings are said to be effective at curbing snoring by reducing the amount of fluid that builds up in the lower part of the legs during the day.

    At night when we go to bed, some of this fluid moves up the neck due to gravity, leading to obstructive sleep apnoea. The condition is caused by a blockage of the airway, usually when the soft tissue in the back of the throat collapses during sleep. Snoring is the result of the vibration of air against the soft tissues. So by reducing the build-up of fluids through better blood flow, snoring is silenced. The study is published in the journal Sleep Medicine.

    According to Dr Chong Yaw Khian who run the Snoring and Sleep Apnoea Clinic at Tan Tock Seng Hospital, wearing socks to bed helps induce sleep by widening blood vessels, so it seems donning on flight socks to bed has more than one benefit.

    In Singapore, flight socks from brands like Scholl and Futuro are available at most Watsons, Guardian Pharmacy and certain specialised travel shops.
