Snoring is one of the most common sleep complaints, and for a lot of people it gets noticeably louder the moment they roll onto their back. The reason is simple: as you fall into deeper sleep, the muscles around your airway relax. Lying on your back lets the tongue and soft tissue settle further back, the airway narrows, and the air passing through turns turbulent. That turbulence is the sound.
The usual advice is “just sleep on your side.” It helps, but most people drift onto their back again within minutes and never know it. That is why side-sleeping alone rarely fixes things on its own.
What tends to help is anything that keeps the throat muscles from over-relaxing: staying off alcohol close to bedtime, keeping the bedroom air from getting too dry, and gentle approaches that work at the throat itself. Stilla sits at the base of the throat and answers a snore with a soft, silent pulse that eases those muscles, so breathing stays smoother without anything in your mouth.
If you regularly stop breathing in your sleep or feel exhausted during the day, that can point to sleep apnoea, which is a medical matter. Please speak to a doctor. Stilla is a lifestyle aid for snoring, not a treatment for apnoea.
