inhaling thru your nose brings things in(your head)----a big no no as far as survival is concerned...repeat do not inhale @ any time thru your nose, that's the mouths job...
Of course that's not just
100% INCORRECT, it's actually the exact
OPPOSITE of correct.
You are in fact SUPPOSED to breathe through your nose and NOT your mouth. That's how mammals (such as humans) are designed "as far as survival is concerned."
- sense of smell is a key survival sense; to smell food, detect noxious substances/gasses in the environment, pheromone attraction of opposite sex, detect predators and other dangers, etc
- nasal passage provides critical physical "filtration" of inhaled air via shape/length of the nasal passage as well as the hair and mucous that line the passage
- air drawn in through the nasal passage is more effectively warmed and humidified than air drawn in through your mouth
Chronic mouth breathing is linked with medical conditions such as higher rates of respiratory tract infections, greater incidence of allergy/asthma problems, dental problems, and other maladies.
In fact, since mouth breathers appear to have a somewhat "slack jawed" look, and mouth breathing can cause or exacerbate bad breath the term "mouth breather" is commonly used in a pejorative fashion for someone lacking in hygiene or intelligence.
PS - if you carefully note the location of your mouth relative to the rest of your body you will see breathing through your mouth "brings things into your head" too
