Today I learned that snot turns yellowy greenish for the same reason that pee turns yellow, dehydration. The snot usually isnt yellow other than when we are sick because usually we don’t have a runny nose while dehydrated except specifically when we are sick.

And also once again, humidifiers save the day because they both tackle the dehydration by putting moisture into your airways and the nature of water in the air helps break up stuff that is stuck anywhere in your airways by lubing it up and making it take its course faster while also freeing up bandwidth for your body to continue shoving more of the sickness out of your body faster which helps you recover sooner.
