A posture that improves your sleep is bound to be beneficial for you. As long as you are active during the day, 7-9 hours of sleep in sub-ideal posture is not enough to be anatomically detrimental. Your body will naturally loosen up during the first few hours of being awake. If you can keep your mouth shut, avoid apnea and never wake up in pain, you are well off.

I also came across different opinions on this. I asked a few experts, and all have different versions. What I realized for myself was that the head should be above the body for the blood to flow. And I sleep on my back. And  also need to sleep on an orthopedic pillow. I recently acquired one here http://pregily.com/orthopedic-pillows/  , and my neck began to feel much better.

Lie on your side. Feel whether your tongue is still central in your palate. Mine isn’t either side. This would likely increase when I slept if the tongue relaxed. The effect of this would even out if you switch sides in the course of the night and don’t have a favoured side. I favour my left side strongly. In fact I find it very difficult to fall asleep other than lying on my left side. Also consider where the pressure of the pillow falls. Is it on the side of the jaw or only higher up on the head? Such pressure on the jaw can put the mandible slightly askew. It is also considerably more than the usual inward pressure of the cheeks, which absent the outward pressure of the  tongue is what has moved our teeth in and why we are here. These effects are very slight but over time they make a difference. This work is as much about removing hindrances, in habit and posture, as it is about putting in effort with the tongue.

Lying on your side is a good idea for those who are learning to keep their mouths shut and breathe through their nose through the night. However, the ultimate goal should be to sleep as you do. I am envious that you have managed this. I consider that my failure to has slowed my progress considerably. Did you just do it? Or did you need tactics to achieve it? If so please share them.

I don't have apnea or wake up in pain, however I'm wondering if one sleeping position has more benefits than the other.

I've tried all kinds of pillows and still ended up with neck problems. I'm hoping no pillow is my solution!

Many years ago I traveled across the country for a friend's party and ended up having to sleep on a hard wooden floor, no pillow or blankets. Just on my back. I woke up 8 hours later totally refreshed, having never woken up once, still on my back. It was one of the best night's sleep I have ever had. For some time afterward I used no pillow, and it was only through being in relationships and sleeping with someone else that I started using one again.  Now that I'm single again I'm in a position to maximize MY sleeping time and so am experimenting with the no pillow method. 

For a long time I slept on my right side. An accident had given me a troublesome SLAP tear in my left shoulder which was worse if I slept on it, so I stuck to my right. I don't think it did anything for my face as I started getting more wrinkled around the right eye, that was smooshed up against the pillow. So recently I took to sleeping on my back again and found that I stayed there all night. Losing the pillow is just the next step. You can "ease" yourself into it gently by folding up a towel into a thin strip and putting it under the curve of your neck. 

One thing I've come to realize recently is that sleeping on your side absolutely causes wrinkles in the face. I was looking at my eye area the other day, and apart from the inevitable crow's feet that come with age, I noticed I have a few wrinkles which intersect these at right angles. Criss-cross wrinkles! And I wondered, what in the hell causes them? The crows feet I can understand - my eyes crease up when I smile or laugh and that's how they're caused. But what about the ones in the other direction? 

Then it hit me - they're from the pillow smooshing my cheeks up when I sleep on my side (which I've done for most of my life until recently). I simulated a pillow with my hand and lo and behold, my cheekbone and eye area creases up exactly where those wrinkles are. 

So there's another reason to sleep on your back I guess. 

So the way I approach this is the following: If you have proper posture, meaning a fairly straight spine, then no pillow all the way. Because 1) it's the most natural way and 2) it does mildly improve / maintain your neck posture. However, if you have to force yourself into proper neck posture, have a kyphotic spine, forward head posture etc. I wouldn't recommend switching to no pillow. If you have to force your neck into the matress to hold a proper neck posture you propably won't be falling asleep as well and if you do, there's no way you can hold that posture up during sleep. So if you do stay on your back, your body naturally tilts your head back which essentially is forward neck posture lying down.

I get much better rest this way... but am trying some other things.  So far, what I attached has worked best.

Check out my post on bed wetting.  It is really good!!!

The healthiest way to sleep on your back is on a flat surface with very little "give". If you sleep on foam, the foam will inherit your body posture, which won't necessarily straighten your spine in any way. On hard surfaces your muscles and body rests optimally and your skeletal structure holds your body. When on soft surface muscles/body do not properly relax. This is why we feel so refreshed and regenerated when we sleep on the ground.

As for me, I used to be a stomach sleeper and had to change to either side sleeping or back sleeping. I went to the better back store and they had a therapeutica sleeping pillow specifically made for side and back sleepers. It keeps my spine perfectly straight when sleeping on my side. Also it helps me to handle with with neck and shoulder pain.

I would like to suggest Bouncy pillow is the best.

Well, you definitely need a new pillow if:
you feel tired in the mornings, and it is difficult for you to turn your neck, and you suffer from headaches;
the uniformity of the filler is broken;
the pillow has lost its shape;
there is a persistent unpleasant odor.
If you have a neck pain, I would recommend buying a special pillow that keeps its form. Since I started using it, my headaches stopped, I didn’t think it was possible))

Would sleeping on your side the wrong way eventually shift your cheek bones or some other structures in your face?  That's why I'm trying really hard to sleep on my back.
