today i learned – fri 14th dec 2018

the cold is officially here in the uk! πŸ₯Ά literally froze into ice this morning πŸ™ˆ so, here’s a cold fact!

#tdil the reason why your nose runs when you’re out in the cold ❄️

if you live in the uk, you’ve probably noticed this recently thanks to the mental cold weather that we’ve been enjoying πŸ‘πŸ» it’s highly annoying πŸ™„

but, as your nose begins to run and you have to sniff horrendously, have you ever just thought to yourself – “nose, why you do dis?!” πŸ‘ƒπŸ»

well, it turns out that the reason is to do with one of your nose’s key functions – conditioning the air that you breathe in 😏.

you see, your lungs quite like air that is warm and humid … freezing cold air is neither of these things πŸ™ƒ in order to fix this issue, it must add some moisture πŸ’§.

however, freezing cold air is usually dry πŸ˜• so your nose has to go into overdrive πŸ’ͺ🏻 to maximise fluid creation … your nose has some reflexes in place that allow it to create mad fluid πŸ‘πŸ»

when this overdrive mode is really efficient … it can create loads and loads of fluid – hence the whole runny nose thing πŸ˜’

and there you have it! the reason for the cold weather runny nose is quite simply your nose overachieving, whilst trying to treat your lungs to some nice air πŸ™ŒπŸ»

byeeeee 😬 #tdil
