A chin sling is like a little hammock that helps keep your chin in a good position while you sleep or nap. It's made of soft fabric and goes around your head under your chin.
Sometimes when people sleep on their backs, their chin might fall forward towards their chest. This can make it harder to breathe, especially if they snore. A chin sling helps keep the chin up, which keeps the airways open and free.
It's important to remember that if you have trouble breathing while you sleep or have sleep apnea, you should talk to a doctor. They can help you figure out the best way to manage your condition. A chin sling is just one tool that some people find helpful.
