Have you noticed that your ribs protrude more than they used to? A flared rib cage (AKA a rib flare) is easier to develop than you may think – and it’s nothing to ignore. If left unaddressed, rib flares lead to neck and back pain and may even cause further injury. Rib flares develop due to an underdeveloped Zone of Apposition, or ZOA, where the diaphragm and abdominal muscles meet. This happens for a variety of reasons, but shallow, poor breathing patterns are a huge contributor. Just like any muscle, the diaphragm weakens if you don’t use it. Nasal breathing not only properly engages the diaphragm, but it also activates our rest and digest response to help the body and mind de-stress. Moreover, the nose warms and filters the air we breathe. Our mouths, on the other hand, provide no filtration or humidification features for breathing. Moreover, mouth breathing places us in a stressed fight or flight state. The development of proper tongue posture is key when it comes to making the switch from mouth breathing to nasal breathing. Diaphragmatic breathing exercises further assist with strong breathing patterns and a stable core. Mouth tape ensures nasal breathing while you sleep, which prevents open-mouth snoring and promotes quality rest.
