Sleep is one of man’s most important routines. Insomnia is not just a dangerous disease but also leads to mental disturbances. The sages and vastu aacharyas of ancient times have studied the process of sleep scientifically and in minute detail. Because of the sleep cycle being connected to the geomagnetic flux vastu aacharyas advice against sleeping facing the north direction. The flow of the magnetic energy of Earth is from the north pole to the south pole. When sleeping facing the north, the magnetic flow of the body and that of the earth, repel each other causing adverse effects in the person. The attraction of unlike poles is something that affects sleeping as well as mind. So sleeping facing the south side will result in the body magnetic flow and geomagnetic flow attracting each other. This will mean that the two forces will not disrupt each other.
Sleeping facing the south and east are most beneficial. Sleeping postures in facing the north and west will cause mental and physical illnesses. A sound and proper sleep is an absolute necessity for a human being. Sleeping for at least 6 hours every day is required for a human being. It has been strictly advised that one should not sleep immediately after a meal. The digestive system working during sleep is not good for the body. This was one of the main reasons why our ancestors had early suppers. According to science, a healthy human being is one who sleeps sufficiently. And this is linked to the factors mentioned above.
