Unfortunately, the answer to your question is, yes, there are serious health risks associated with second hand smoke exposure, which you can get from living with someone who smokes all the time.
Among the potential health risks perhaps most serious is the risk of long term damage to the lungs, including the development of emphysema and even lung cancer. Furthermore, exposure to smoke chronically is associated with a range of other problems, including nasal allergies, chronic sinusitis, and asthma
I suggest that you set up a visit with your primary care doctor
for a general physical examination. They will be able to check out your overall health and help determine if you are suffering from any ill health effects from your exposure to cigarette smoke. Make sure to mention to them if you have any troubling symptoms, such as nasal congestion, cough, sinus pressure, or sore throat
In addition, you may want to encourage your father to go see his own primary care doctor. These days, there are many excellent medications and other therapies that can be used to help quit smoking and, if your father is interested in considering quitting, his primary care doctor will be able to help him do it.
