LINK: "Is the way you sleep making you ill?" article in the Daily Mail Newspaper
MY COMMENT:
Missed one out and confirmed by my doctor. When finding it hard to breathe, sleep at a 45 degree angle upright, as to alleviate pressure in the lungs. I did this on a sunlounger that could tilt when I had a nasty chest cold and found I could take in air better and get a good night sleep too.
