Why you should never sleep with your head in North direction?

It is many times said in India that while sleeping you should never have your head in the north direction. Many mythological stories are given to explain this to common people. But there is a scientific reason for this particular question.


One must know that earth acts as a giant magnet. Earth's geometrical north and south pole are also its magnetic north and south pole respectively. The magnet has a property to attract (or repel) various metals and other magnetic substances. So earth is attracting various metals toward the poles. Countries in northern hemisphere are more attracted by north pole.

The heart pumps blood such that it apply more force in upward direction then in downwards direction. As in upwards direction it has to work against gravity. While in downward direction gravity plays its role to bring blood in lower parts of body. So it pumps sufficient blood in brain.


Human blood contains a sufficient amount of Iron in it. This iron is attracted by  earth's north pole. So when we sleep with head in north direction blood moves towards brain. Excess blood gets accumulated in brain. 

This causes disturbance in the brain. This would affect your sleep. You would not be able to sleep properly. In some cases due to some disorders in brain or old age peopled have face brain hemorrhage or instant death. This is not the case when you are vertical.  

You can sleep in any other direction. But east is considered best.

It is for the countries in northern hemisphere only. If you are in southern hemisphere like in Australia, you should not sleep with your head in South direction.
