My Newest Hypermiling Technique... CONFIRMED!!!

[aalb1]

Breathe Through Your Nose!!!!!

Around winter time we all know that the less we use our vent heaters the quicker our car warms up to a greater fuel efficiency territory. In my case, with Pulse & Engine-Off Gliding, my car doesn't even hit normal operating temperature on my 14 mile morning commute. Thinsulate and added layers keeps my body warm but I still have issues with windows fogging up.

But now I added a new hypermiling technique that helps keep my window from fogging up as much by Breathing Through My Nose! I notice a significant amount of less water vapor comes out by exhaling through my nose instead of my mouth. Also when I exhale through my mouth the water vapor seems to head straight for the windshield immediately fogging it up. Exhaling through my nose directs it down and away from the windshield fogging it WAY LESS!

Now for a few questions: It seems that when its colder out it is natural instinct for me to breath through my mouth. Why is that? Also wouldn't breathing through my mouth make my body temperature colder? Kind of like the "Panting Dog Effect?" Therefore am I right with my thinking that breathing through my nose would keep more body-heat in?
