Not ALL snoring is harmful. The reasons for snoring stem from the relaxation of throat muscles when you sleep. Less airway volume can mean that the relaxed throat vibrates when you breathe. It’s the universal cause of snoring (harmful or normal) The tongue is one of the main factors in snoring and sleeping with mouth open. During sleep, the muscles in the back of the mouth, nose, or throat become relaxed and breath flowing through the airway causes them to vibrate or flap. When you go to sleep, the primary muscles of your tongue and your throat relax. For you to keep your airway open, support muscles for the throat must hold firm. Not all snoring is sleep apnoea. Breathing noise or ‘snoring’ can be normal. The restricted airflow results in a rumbling, rattling sound that occurs when air flows past the relaxed tissues. Snoring sounds range from quiet whistling or vibrating to a loud grumbling, snorting, or rumbling. It results when the upper airway, specifically the throat and the nasal passage, vibrate from turbulent airflow during breathing while asleep. This commonly affects the soft palate and uvula, the tissue that hangs down at the back of the throat. Narrowing at the base of the tongue may also play a role. The root cause of snoring is when the air you’re breathing doesn’t flow smoothly through your nose and/or throat when you’re sleeping. Instead, it bumps into the surrounding tissues, which causes a vibration. The resulting vibration makes the snoring sound as you breathe. Your tongue position may also play a part. Snoring is caused by things such as your tongue, mouth, throat or airways in your nose vibrating as you breathe. It happens because these parts of your body relax and narrow when you're asleep. Sometimes it's caused by a condition like sleep apnoea, which is when your airways become temporarily blocked as you sleep. Snoring is the sound that air makes when it passes across the relaxed or loose tissues of the upper airway.

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.
