What causes that saliva smell that you get in your mouth after breathing a lot in freezing weather? - eviltoast

In a similar vein, sometimes my breath feels sort of ‘milky’, even though I haven’t eaten any dairy products. What could that be?

Edit: Apparently this is not normal??
Try this experiment to see if you get the taste as well:
Next time it’s freezing outside, sprint for a bit so that you’re left taking deep breaths in the cold air by the end of it. That’s when I get the taste. My saliva also feels a bit thicker, probably due to the cold air.

      There’s no way you’re breathing enough ozone anywhere on walkable Earth for you to taste it. However trapped CO2 form the surrounding air in water particles flowing in the air may explain this, the taste is bitter, slightly sharp.
