I am a 72 years old male and I was diagnosed with moderate OSA last May. While waiting for the CPAP device I added a few pillows (I forget where I heard that) and it helped a lot (although it put a strain on my back). I had trouble getting used to the CPAP mask and it did not seem to help in any significant way (more than the pillows), so I sent it back. After a month or so I moved the pillows between the mattress and the box spring so that the head of the bed was about 4 inches higher than the feet. Now on I am sleeping on a slope (about 5%) and I do not have the strain on my back any longer and the sleep apnea symptoms are greatly reduced. I have much more energy than before and my blood pressure seems to be lower (although I continue taking HBP medications).
This is a very simple and inexpensive remedy and I am curious if others have tried it. I am thinking of rasing the head of the bed more but I would like to know other people’s experience before I do that. I cannot think of any possible adverse effects but one can never be sure.
