According to ancient traditions like vastu shastra, the best direction to sleep in is toward the south. This theory is also supported by some recent research1. This means that when you lie in bed, your head is pointed south2, and your feet are pointed north.
What direction should your head face when sleeping?
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.
Which direction should you sleep scientifically?
East and South directions are the most ideal directions for sleeping. Sleeping with your head facing South reverses the negative effects of North direction and thus, protects you from several health problems. It keeps your blood pressure under check and also maintains a steady blood circulation.
