I was reminded of this just now while reading another post. I remember reading that some allergies (like food allergies) get progressively worse with exposure, but after googling I couldn’t find a solid answer, and some results even said it was a myth.
In my personal experience, my tree nut allergy went from very mild as a kid to life threatening by my twenties. So if it’s not exposure that causes worsening allergies, what is it actually?
Is there something that does make allergic reactions get worse over time? Or is it just a thing we don’t actually know the reason for?
