Do you snore in your sleep? Hypoglossal Nerve Stimulation (HNS) is a relatively new therapy for sleep apnoea & snoring ⚡️ How it works: Before going to bed, the sleep apnoea patient uses a remote to turn on the device. Once it is on, the device monitors the person's breathing. When they inhale, the device sends gentle electrical signals to the hypoglossal nerve, which controls how the tongue moves. This stimulation helps push the tongue forward and opens up the airway in the back of the throat,
