Micajah,
Some idiot didn't get the science facts right, there is a DOMINANCE of one nostril, and it shifts every couple of hours to another one, but it sure is not 100% one nostril, in normal circumstances.

#5 Doesn't explain why raised hair follicles would help with warmth. It's because the erect hair (once upon a time fur) would trap air which is an effective insulator for the same reason fiberglass wool is used as insulation in the walls in some forms of construction (eg, Canada & USA).

Goosebumps are your skin trying to keep warm

 

Due to having limited body hair, goosebumps don’t work as well as they do on squirrels or birds. Surprisingly though, goosebumps are the bodies way of trying to stay warm. There is a tiny muscle, the arrector pili, that contracts at each hair follicle to pull the hair upright.
