Sleep positions can make a big difference in how your back feels. If you sleep on your side, draw your legs toward your chest and even opt to put a pillow between your legs for optimum positioning. While sleeping on your back, on the other hand, put a pillow under your knees. Use a pillow for support under your neck. If you are like me and you must sleep on your stomach to be comfy, put a pillow under your pelvis and lower abdomen, say the experts at The Mayo Clinic. If it causes too much strain to have a pillow under your head, do without while on your tummy.
Lastly, on a side note, BBC news reports that like body language when we're awake, your sleep position can say a lot about your personality. See this piece at :
Thanks for this bit of news....quite interesting and helpful. Same goes for the personality/sleep position comparison. I sleep on my side, curled up, but I'm hardly an introvert! But interesting none the less.
To add on to Teresa's post, find the right position to keep yourself comfortable, and also the right mattress. For people with back problems, this can be vital to waking up in little or no pain at all. My body responds better to a firm mattress than a softer one, but not too firm as to not allow for my body to sink a little into the mattress.
Make sure you take advantage of all the floor samples at the local mattress stores. That's what they're there for when you're in the market.
I agree with what you said that sometimes snoring is caused by the wrong position during sleep. I also snore before. My wife said that it became worst when I sleep on my back. Mine, I have used Sona pillow and my snoring stop. At first, it was really uncomfortable as I need to sleep on side-lying position. But my wife was satisfied with the results. That's why I am satisfied too.
