It's more likely they are not suffering from back problems because of their way of life, not their way of sleeping. We know factually how sitting on the computer for long hours changes the spine's curvature especially on the neck and also the shoulders.I found this study a while ago and I think it's pretty interesting to see how most modern sleeping and resting positions are so different than the natural sleeping/resting positions adopted by those without mattresses and chairs. Apparently, those that use natural positions suffer from less back problems, although the evidence is only anecdotal.

The structural changes in spine curvature in unlikely unless in the most extreme cases. Most often it is the muscles of the upper torso, neck and back that are stretched in those unhealthy postural positions that lead to the pain and discomfort.It's more likely they are not suffering from back problems because of their way of life, not their way of sleeping.

I meant exactly what you said but I was less detailed about it :tongue:. Prolonged sitting is a way of life that changes how our muscles are used, creates imbalances and the spine curvature changes as a result. I'm not saying it's permanent, at least in theory, because in practice they can be practically permanent because we don't change our way of life.The structural changes in spine curvature in unlikely unless in the most extreme cases.
