I run a special air cleaner. On top of that, the Doctor found that I do have Contact Dermatitis. I have to use two types of creams (prescription), and am supposed to wear cotton gloves at night. All of this has not stopped me from tying since that is my side business and a passion. As to outdoors, I find that I breath much easier up in the Mountains. A lot to be said about good clean Mountain air !!!!!!!!!!!
