PHILADELPHIA (CBS) – If you have a Christmas tree it can be a source of family fun and togetherness but it may also be a source of coughing and sneezing.

Most people don’t think about it but a certain percentage of people are actually allergic to Christmas trees.

If you find that each year you experience nasal stuffiness and congestion this time of year, it could be the tree.

It’s very important if you have a Christmas tree allergy to recognize it.

Obviously, you can get an artificial tree, or you can just be careful about being in the room where the tree is and minimizing your exposure as much as you possibly can.

Of course trees are not the only concern. Another thing to consider is exposure to mold.
