I had a tendency for allergies for most of my life, until we got our daughter who increased our overall level of dirtiness acceptance and brought in new viruses every other week when she was little. Suddenly my allergies dropped. I made a test and I had no positive marker. This went on for a couple of years. This has changed since the lockdown. I am sneezing again all the time and wake up with sore throats, in the way it was typical. Even stronger than before. The immune system needs work to do.
