Breathing through the nose is essential for optimal health from "summary" of Breath by James Nestor
Breathing through the nose is essential for optimal health. Our nose is a highly sophisticated organ that is designed for breathing. It filters, warms, and humidifies the air we breathe in, preparing it for our lungs. When we breathe through the nose, we activate the diaphragm and engage the lower lobes of the lungs, which allows for more efficient oxygen exchange. This type of breathing triggers the parasympathetic nervous system, which helps us relax and reduce stress. In contrast, mouth breathing can have negative consequences for our health. It bypasses the filtration system of the nose, allowing harmful particles and pathogens to enter the body. Mouth breathing also leads to shallow breathing, which can result in reduced oxygen intake and poor oxygen exchange in the lungs. This can have wide-ranging effects on our overall health, from decreased cognitive function to weakened immune response. Moreover, nasal breathing plays a crucial role in maintaining the correct balance of gases in our blood. When we breathe through the nose, we increase the levels of nitric oxide in our bodies, a molecule that helps dilate blood vessels and improve circulation. This can have a positive impact on cardiovascular health and athletic performance. In addition, nasal breathing is closely tied to our sleep quality. When we breathe through the nose during sleep, we are more likely to enter the restorative stages of sleep and experience better overall sleep quality. This can have a profound impact on our energy levels, mood, and cognitive function throughout the day.- The simple act of breathing through the nose can have far-reaching effects on our health and well-being. By understanding the importance of nasal breathing and practicing it regularly, we can support our body's natural processes and promote optimal health.
