I was told that r right lung has 3 lobes for distributing air. Where as r left lung has ownly 2 bc it has to compensate for r heart

I have noticed that if I sleep on my left side I do not breathe so well also I will cough more I am better on my right side I think if you look at xrays the left lung is partly behind the heart when you sleep on left side the left lung does not get as much air I might be wrong in thinking that perhaps somebody might be able to tell us differently

I have one of those pillows had when I had my gall bladder out 14 years ago it helped me because I like sleeping on my right side it is only when I turn on my left side I cough more

Only when fighting a lung infection.

I had that also when I was real flimmy and congested.
