Almost no one pays attention to this state of affairs, and or rather, an ordinary person doesn’t even know about it, vaguely guessing only with a runny nose, which for some reason lays one, then the other nostril.
But it turns out that we constantly breathe only one nostril, while the body alternates both, and this process is called nasal by biologists cycle. During normal functioning of the body, our brain (or nervous system) changes the nostrils every few hours (on average after 4-5 hours at night and after 2-3 hours during the day), and each person has such the cycle is individual, but if it does not occur, it is worth thinking about your health. As a rule, in this case there is some kind of pathology in the structure of the nose, for example, a nasal disturbance partition.

Scientists still do not really know why in the process of evolution human nature created this nasal cycle, although, undoubtedly, it does not random and obviously helps us survive in our environment reality. There is only an assumption that such a mechanism allows a person to significantly enhance the sense of smell, since one the nostril breathes, and the other at this time captures the smell, delaying molecules on the mucous membrane and analyzing them: speed dissolution in nasal mucus of each substance is different, but in any case – not instant.
And although this is just a theory, but it looks like the truth, although some researchers suggest that the nasal cycle is much a more complex mechanism that affects not only the sense of smell, but also the psyche of man.
In any case, now you know that you breathe only one nostril, while the second is busy with unknown. Unknown so far only our consciousness, because our body knows everything perfectly and works in most cases like a watch …
