Is sleeping with our head towards the west direction advisable, as per Vastu?

According to Vastu Shastra, sleeping with one's head towards the west direction is considered appropriate, but the most excellent direction is considered to be with the head towards the south direction and the feet towards the north. Because of this, it is observed that one attains excellent health, comfortable sleep, and peace in life.

Looking from a scientific perspective, the Earth's magnetic field is north-south and is spread across the poles, and in the human body, various types of iron content are found in the blood. The Earth's magnetic field has an effect on blood circulation in the human body. Therefore, when sleeping according to the direction of the magnetic field, a person gets excellent sleep and becomes active with completely renewed energy. That is why it is stated in Vastu Shastra that sleeping in a north-south alignment is more beneficial.
