Pundit ji, I am being told not to sleep with my head towards North? Is there any reason behind it?
Myth is that it invites ghost or death but since says that it is because human body has its own magnetic field (Also known as hearts magnetic field, because the flow of blood) and Earth is a giant magnet. When we sleep with head towards north, our body’s magnetic field become completely asymmetrical to the Earth’s Magnetic field. That cause problems related to blood pressure and our heart needs to work harder in order to overcome this asymmetry of Magnetic fields. Apart from this another reason is that Our body have significant amount of iron in our blood. When we sleep in this position, iron from the whole body starts to congregate in brain. This can cause headache, Alzheimer’s Disease, Cognitive Decline, Parkinson disease and brain degeneration.
