One Nostril: I’m cool
Other Nostril: They have taken the bridge and the second hall. We have barred the gates but cannot hold them for long. The ground shakes, drums… drums in the deep. We cannot get out. A shadow lurks in the dark. We can not get out… they are coming.
I actually know this one! Here’s a 3 minute SciShow video that explains it.
Here’s the “I don’t want to watch a youtube video right now” Highlights:
- About 80% of people have a nasal cycle
- This cycle swells one nostril and the other remains more open
- They switch sides every few hours
- They do this to protect cilia and aid in better smell sensation, and other things probably
- It does this all the time, you just realize it more when you have congestion and inflammation blocking your nostrils even more
