Is it healthy to never catch colds?
Are you someone who hasn’t had a cold in a really long time? Or maybe you know someone like this?
It’s often unquestioned truth that it’s a sign of health to “never get sick.” But is this really the case?
There are 3 main patterns in people who never get sick:
- someone with an immune system so underactive, that they don’t produce an immune response or inflammation when presented with bacteria or viruses
- someone who is inflamed but has poor ability to feel their own internal state (known as interoception) so may be sick but doesn’t really feel it
- someone who is actually robustly healthy so they don’t tend to catch cold and viruses
In this lab note, I’ll walk you through these patterns so that you can learn to spot them.
