Though you may not pay attention to it unless you're sick, you're always breathing more heavily from one nostril1 than the other.
 
除非生病了,否则你可能并不会注意到,你的一个鼻孔总是比另外一个呼吸更费力。
 
During the day, the sides switch and the other nostril goes into 'work mode', but why?
 
This process is automated2 by the aptly named autonomic nervous system, which is the same system that controls many things your body does all by itself such as digestion3 and heart rate.
 
For your nose, this system controls your 'nasal cycle', so that each nostril operates effectively.
 
The nasal cycle happens, according to the US National Library of Medicine, several times during the day, and is only brought to your attention if your nose is clogged4 up more than usual.
 
In order to open one side of your nose and close the other, your body inflates5 tissue with blood in your nose.
 
"Increased blood flow causes congestion6 in one nostril for about 3 to 6 hours before switching to the other side. There is also increased congestion when one is lying down, which can be especially noticeable when the head is turned to one side," Jennifer Shu reports for CNN.
 
It's believed that this cycle helps round out your sense of smell. As Matt Soniak reports for MentalFloss, some smells are better picked up by fast moving air through your nose, while others take more time and are detected better with slow-moving air.
 
If one side of your nose is wide open and the other is slightly closed, you get all of the smells.
 
The process also gives each side of your nose a break, since a constant stream of heavily flowing air can dry it out and kill off the small hairs that protect you from foreign contaminants.
