A 1994 study suggested that breathing through alternate nostrils can affect brain hemisphere symmetry on EEG topography. [10] A later study in 2007 showed that this cycle (as well as manipulation through forced nostril breathing on one side) has an effect on endogenous ultradian rhythms of the autonomic and central nervous system. [11]
It investigates the history of how humans shifted from the natural state of nasal breathing to chronic mouth breathing. Nestor explores research that argues that this shift (due to the increased consumption of processed foods) has led to a rise in snoring, sleep apnea, asthma, autoimmune disease, and allergies. It includes Nestor's first-person ...
Mouth-to-face - Used on both animal muzzles and infants under 2, as this forms the most effective seal on both the mouth and nostrils; Mouth-to-mask – Most organisations recommend the use of some sort of barrier between rescuer and patient to reduce cross infection risk. One popular type is the 'pocket mask'.
Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
In the early 20th century, "mouth-breather" was a technical term used by doctors to describe children who were breathing through their mouths due to an underlying medical condition. English lexicographer Jonathon Green notes that by 1915, the phrase "mouth-breather" had developed a pejorative connotation within English slang, defined as a ...

Fish do not breathe through noses, but they do have two small holes used for smelling, which can also be referred to as nostrils (with the exception of Cyclostomi, which have just one nostril). In humans , the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking.
Empty nose syndrome (ENS) is a clinical syndrome, the hallmark symptom of which is a sensation of suffocation despite a clear airway. This syndrome is often referred to as a form of secondary atrophic rhinitis .
