What causes that saliva smell that you get in your mouth after breathing a lot in freezing weather?
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.
I would imagine it's simply changes in the bacterial biome of your mouth, but I'm curious too. Especially as to why that saliva smell also comes off snails. 🤢
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.
My guess is similar to everyone else, that the dryness is affecting it. Cold air might dry things out, especially if you're breathing heavily through your mouth since your nose feels cold (and cold weather can be strenuous). That might cause it to get dryer, or decrease saliva production entirely and make things thicker
This might be a weird thing to experiment with, but that might give you some areas to test out
No I don't think it's that. It's a taste I get in my mouth, after eg. running outside when it's >0°C which means breathing a lot, possibly meaning my mouth is dry? Yeah maybe it's to do with the mouth being dry...
