Fireplace users are more likely to develop lung cancer
According to a 2010 study done by the Environmental Health Perspective, people who use their fireplaces regularly are more likely to develop lung cancer than those who don’t have one. The explanation is that if you are exposed to high levels of wood smoke, you will automatically inhale a large amount of harmful gases that directly affect your lungs, so it can lead to lung cancer in the long run. Being exposed to wood smoke is similar to smoking, so try to stay away from fireplace smoke as long as possible.
“Repeat exposure can permanently damage the lungs and increase the risk of cancer similar to smoking,” said Dr. Tong.

Pay attention to what you burn
As we said before, it’s very important what you choose to burn in your fireplace. Sadly, there are not many things that you can burn and can be safe for your health as well. “Items that burn inefficiently create the most carbon monoxide,” he says. “Avoid burning wet wood, cardboard, paper with color print, Christmas trees, painted or treated wood, plywood, particle board or chipboard or plastics.”
