Conversely, sleeping on your side isn’t very good for a lot of your joints. For instance in your diagram, that position is very bad for her hips and compressing her lungs. I still sleep on my side because it’s my preferred position but I have to have a knee pillow to keep my hips and knees aligned, and I try to have a pillow hugged to my chest to keep my spine and shoulders from crunching lol.
