Absolutely. I’ve read some studies suggesting that small exposures, like a few minutes of cold water immersion or playing in the dirt can actually train your immune cells to respond more quickly.
That’s a tough experience, I’m sorry to hear about your acquaintance. You’re right though, in open wound situations, cleaning and treatment are VITAL. The point here is more about how daily handwashing can become excessive…absolutely not recommending avoiding hygiene altogether.
Think this is an astute way to go about things!
