Yeah, I think wearing masks in response to the immediate threat is a good thing (along with continuing to get out of the house and interacting with the world), and setting them aside later is the best course. Our immune systems tend to weaken when not being regularly challenged in a too-sterile environment.

“I’m a sound believer that we’re too clean of a society,” says Dr. Christopher Carpenter, section head of infectious diseases and international medicine at
Beaumont Hospital in Royal Oak, Michigan. “Our fear of germs has pushed us too far into trying to keep everything safe and sterile. That extreme is harming us more than it’s helping us.”
“We are getting far too sterile,” adds Kiran Krishnan, a microbiologist and chief scientific officer for Microbiome Labs, based in St. Augustine, Florida. “Exposure to microbes is an essential part of being human. Most of our immune system is comprised of tissue that requires activation by the microbes we’re exposed to. The immune system requires the presence of friendly bacteria to regulate its functions. Think of the immune system as an army, with tanks and missiles but no general to lead them. That’s the role friendly microbes play in your body; they’re the general.” The vast majority of microbes, 97% to 99%, are benign or beneficial, and they are the best protection to fight pathogenic microorganisms, Krishnan says."
