The lights and smell of Christmas trees make the holidays come alive. But sap, pollen, spores, and mold found on trees can cause allergic reactions, according to Lauren Browne, M.D., and increase the chance of an eczema flare.
What you can do: Rinse off the tree with the garden hose, if you can. When dry, wipe the trunk with a diluted bleach mixture. Wear gloves when handling and decorating the tree. If you use an artificial tree, be sure to rinse it off first to get rid of dust and mold.
