I sleep in one position but analyze: is it optimal for my body? Map the position effects: back, side, stomach - each affects breathing, spine alignment, pressure points. Calculate: if I changed position, would pain decrease and sleep quality improve? Show me the position analysis: this position is best for my specific issues (snoring, pain, reflux). Give me the retraining: how to learn new sleep position. Include: whether my position is causing problems, optimal position for my issues, and how to change if needed.
