Breathe with Your Nose, Eat with Your Mouth
Breathing exercises have long been touted by therapists as effective ways to combat stress and anxiety, or just to loosen up. And it’s true. Taking a few deep breaths can make even the most stressful situations more bearable. But why is that?
It turns out your breathing can have a direct impact on your body. Similar to how smiling can change your mental state, slow, deep breathing can impact you physiologically.
Mouth Breathing and Your Sympathetic Nervous System
Mouth breathing can activate your “flight or fight” response. Take this example. You’re walking down the street when an aggressive dog comes barreling towards you. As it comes towards you, you begin to take quick, shallow breaths. Because you’re taking shallow breaths through your mouth, the oxygen reaching your lungs only stimulates the sympathetic nerve endings in your upper and mid lobes. Your sympathetic nervous system is responsible for activating your flight or fight response, so as the dog barrels towards you, you prepare to either fight or run away.
While helpful in situations like this one, habitual mouth breathing can sustain a flight or fight response. This makes it difficult for the body and mind to rest, digest, repair and grow even when there is no impending danger.
Nose Breathing and Your Parasympathetic Nervous System
Your nose, on the other hand, is the primary organ responsible for oxygenating your body. When you breathe through your nose instead of your mouth, air is able to reach the lower lobes of your lungs, stimulating your parasympathetic nervous system which is in charge of rest, digest, repair and grow. Known as the “rest and digest” system, this part of your nervous system kicks in when you are digesting food or engaging in relaxing, restful, or pleasurable activities.
When you are unwinding on the couch or having a quiet evening in, your breathing slows and becomes deeper.
Parasympathetic breathing has been linked to improved sleep, gut, and mental health (among other things). The key is breathing deeply through your nose versus your mouth. Nose breathing has also been shown to improve your sleep and exercise performance.
What Does This Have to do with Dentistry?
Mouth breathing during sleep has been associated with disrupted sleep and obstructive sleep apnea. Mouth breathing can also increase your risk for dry mouth and cavities. Saliva is a natural buffer from the acids that break down tooth structure. With a dry mouth, the incidence of cavities may increase.
Mouth breathing is chest breathing which leads to shallow “fight or flight” breathing. In the state of “fight or flight” muscles are activated and you could find yourself grinding your teeth. The digestive system is somewhat inactivated during “fight or flight”. Your teeth are a part of the digestive system and they may not be getting the oxygen and nutrients needed to be healthy. In fact, teeth may become more sensitive. Dr. Felix Liao coined the term “tooth angina” where teeth hurt for “no reason” because their oxygen supply is restricted from being in “fight or flight” instead of the parasympathetic digest and rest state.
Your upper airway (nasal passages, oropharynx, etc.) is key to being able to breathe deeply and profoundly. If your upper airway is underdeveloped you will have a harder time breathing deeply through your nose. When you can’t breathe through your nose, you are forced to breathe through your mouth which can in turn activate your “fight or flight” response, thus keep you from getting restful sleep.
The root cause of an underdeveloped upper airway may be an underdeveloped jaw. When the jaw grows properly, it allows other parts of the mouth to develop properly as well.
Vivos-Craniofacial solutions do just this. By stimulating jaw development, Vivos oral appliances urge your jaw growth towards its genetic potential. This could open airways and help you grow, breathe, sleep and thrive!
