November 6, 2019 As you fall asleep the soft palate in your mouth, your tongue, and throat relax, which causes a partial blockage of your airway. As air tries to get it through it causes the tissues to vibrate. The more your airway narrows the louder the snoring becomes. A soft palate, thick throat tissue, and weak throat muscle tone are some physical reasons. When you sleep, all of the muscles in your body become more relaxed. Snoring is caused by air squeezing through the narrowed or blocked airway. In some cases, a person snores when their tongue or the tissue in the back of the throat relaxes while they sleep. Airflow is constricted, causing a vibrating sound. Naturally, when a person sleeps, their muscles relax slightly, a process that can cause the airways to shrink. That tissue places pressure on the nasal passages, keeping air from freely flowing. During waking hours, the tissues in the throat and upper airway are open, and air enters the lungs easily for most people. During sleep, the soft tissues and tongue relax. This can partially block the airway. If the air coming in and out of the airway meets resistance, vibration can occur, causing snoring. Sometimes the brain cannot properly signal the muscles that control breathing, may also produce snoring. Snoring occurs when your upper airways narrow too much, causing turbulent airflow. This, in turn, makes the surrounding tissues vibrate, producing noise. Snoring is a noise made as we breathe during our sleep.
