do is go to head the same time of the day. carbon monoxide poisoning. it s not just stoves it s heating systems ovens particularly if you run a car in a gar raj. be careful about leaving your car in the gar raj. burners in basements can be a risk. make sure you have your fuel burners serviced regularly have a carbon monoxide monitor make sure the batteries aren t flat. replace them regularly to protect against carbon monoxide. we hear the stories where people try to stay warm and do things you mentioned not to do. people still heat their homes with ovens. things like that increase the risk of carbon monoxide poisoning. thank you very much dr. phil
