Frankly, go outside when you're sick.
Most Americans stay inside too much, so I bet you do too.
Learn to be okay if you're not the exact right temperature.
Get comfy with grabbing a blanket or sweating.
The outdoors aggravates your sinuses?
I feel ya!
That's me too.
See if it stays true once you've done it for a few weeks.
For me, it gets worse for a bit but then gets better and stays better.
It’s gotten easier every year.
