Which is the position most helpful for you heart. I can remember reading one time that sleeping on the left or right caused my pressure on the heart,is that even true?
Personally I sleep on my front but just wondered if there was any beneficial sleep poistions or harmful ones?
If the person is not mobility limited, its just about impossible to control the position that they sleep in without physical restraint. One you are asleep, the body takes over and will move to the position that is most comfortable or least uncomfortable. Anyone who tells to to sleep in this or that position for this or that health benefit doesn't know what they are talking about.
So it doesn't matter how you sleep and sleeping in one position doesn't put more pressure then others? There must be one that makes your heart beat more efficient?
I recall (I think in some film) the claim that sleeping on your right put strain on the heart; but i dismissed it as unlikely. We evolve to cope with all that, the heart is fairly central anyway. I would doubt it made a measurable difference during a lifetime. Lay however you get off to sleep best and stop worrying about whether it is the best position or not. Lying awake worrying will be more detrimental.
Either that or take you heart out at night and put it in a glass by the side of your bed for safekeeping.
The only tenuous link I can think of is that you should put a pregnant unconcious woman into the recovery position lying on her left to prevent pressure on the interior vena cava
