I am aware cedar dust or shavings can cause a reaction in some people.
Woodworkers have to stop using that timber if they are effected by it.

"What are the symptoms of cedar allergies?
Cedar fever symptoms may include itchy, watery, red eyes; nasal congestion, runny nose and sinus pressure; sneezing; sore throat and fatigue.
Despite its name, cedar fever doesn't cause a fever, but inflammation triggered by the allergic reaction may raise the body temperature slightly."
