Nature’s millions years’ of evolutionary design has already predisposed mankind to proper sleeping position and posture.
Sleeping posture should be seen as part of overall posture. This article speaks about treating pains with adjusting sleeping positions (and some parts are even inaccurate–for example, with acid reflux, do raise the bed, but don’t prop the head with pillows as article describes, because this bent head-chest position pushes the esophagus closer to acid). But, the question remains of how is it people have differing sleeping pains to begin with? How is it that different sleeping positions relieve, or should we really examine using reverse logic, what position-posture caused the pains?
Artificial comfort devices always has some kind of negative affect on evolutionary design, and the bed and pillow are artificial devices. State-of-nature sleeping surfaces are usually relatively firm and without pillow. On such surface, the optimal evolutionary position is most frequently sleeping on the back.
So, how is it that sleeping backside is less common? The bed and pillow enable these other positions, and over long time, contribute to the mentioned pains. To properly solve these pains, the view needs to be taken of incorporating posture-positions and ergonomic furniture during daytime, including sitting and head angles, (chairs, desks, shoes, and even eyeglasses are all artificial devices!) as well as degree of physical activity.
This is not to say changing sleeping positions won’t alleviate pains. It does say that to prevent such pains involve changing the ergonomic environment daytime and nighttime, so that the efficient-Nature-designed body doesn’t have the pains to begin with.
