A new look at sleep position via head slant.

We investigated whether the degree of plagiocephaly (P) (head slant) would predict the particular "position of comfort" adopted prior to sleep. A marked flattening of the right occipital bone (left-dominant occipital plagiocephaly) was noted for the majority of our subjects, coupled with a tendency to prefer a right-sided "position of comfort". Two subjects exhibiting right-dominant occipital P adopted an extreme left-sided sleep position, providing further support for this relationship. We call attention to the possibility that the "position of comfort" adopted prior to sleep, may be a variable of relevance for the entire sleep cycle.
