actually, I think Feng Shui talks about this and has recommended direction to align with
gpt
Vastu shastra is primarily concerned with space. This is why the scientific principles are widely adapted in Indian architectural use and design.

When it comes to sleeping direction, it’s believed that space (“panch bhutas”) directly interacts with the wind, sun, and other elements to affect our well-being.

The recommended sleeping direction per vastu shastra is that you lie down with your head pointed southward.

A north-to-south body position is considered the worst direction. This is because the human head is considered to have a polar-like attraction, and it needs to face southward to attract opposite poles while you sleep.
