So, in Hindus, we lay down a person with his head to north and feet in south when they die. It is described as located in the south of the universe and It is also the abode of Yama, the god ofĭeath. Naraka (Sanskrit: नरक) is the Hindu equivalent of Hell, where sinnersĪre tormented after death. The reason we don't keep the head in the north and legs in the south is because south direction is associated with Yamalokam. All these things don't happen in one or two single night but it happens if the person has a daily habit of sleeping in a north direction. When we sleep in this position, iron from the whole body starts to congregate in our brain which can cause a headache, Alzheimer’s Disease, Cognitive Decline, Parkinson disease and brain degeneration.

Apart from this, another reason is that our body has significant amount of iron in our blood. That cause problems related to blood pressure and our heart needs to work harder in order to overcome this asymmetry of Magnetic fields. When we sleep with head towards north, our body's magnetic field becomes completely asymmetrical to the Earth's Magnetic field. Science says that it is because the human body has its own magnetic field (Also known as hearts magnetic field, because of the flow of blood) and Earth is a giant magnet. For more information read Narak article from Wikipedia. This is one of the strong reason that people avoid sleeping head towards north direction. Normally when a person dies, his/her body should be kept in a position like head towards north. It also said that the Yamalok ( hell ) is located in the south of the universe and beneath the earth. The south corner is considered as a direction of Death. Posts with unsourced content may be edited or deleted. Want to improve this post? Add citations from reputable sources by editing the post.
