As long as your house has plenty of ventilation, it is safe to have a fireplace inside. Wood fireplaces may seem a bit outdated, however many houses still have them. For those with weak lungs or who suffer from difficulty in breathing, it is important not to sit in the same room as a fire for long periods of time. This applies to healthy people as well, and even if there is an electrical fire in the room. If you can’t breathe comfortably, put the fire out immediately.
