If your sniffling and sneezing coincide with the arrival of your freshly cut Christmas tree, you could be reacting to skyrocketing mold spore counts. If you must have a real tree in your home, prevent allergic reactions for guests and loved ones by hosing your tree down, spraying it with a mold-resistant sealant like M-1 Sure Cote,
and allowing it to dry before bringing it indoors.
Mold spore counts might be lower with living trees,
and lower still with artificial trees. But, keep in mind that some mold can grow on living trees in nature and that dust accumulates while artificial trees are in storage. Also, ask growers about the pollination behavior of your tree: Mountain cedar trees pollinate in late November to early December, so allergy sufferers should steer clear of that variety. Allergy sufferers should consider wearing an allergy relief mask while decorating and keeping an air purifier in the room of the display.
