Hindu Traditions and Scientific Analysis#2-Why you should not sleep keeping head towards North.

I have been asked by my Grandfather not to sleep keeping head towards North and the reason he has given that there are earth magnetic poles. At the age of 8, i was not able digest the concept of magnetic fields and the same magnetic fields haunted me till age of 18 through a subject called physics.



Later in life I have came across many article that we should not do sleep towards north.

Hindu Traditions and Scientific Analysis#1-Why old people suggest to wake up on right side

From my childhood, my grandfather ask me to wake up on right side. Means, while getting up from the bed someone should face the right side and get up from the couch. I curiously asked many times to him, why so? .
The answer is the entire day will become promising if i follow, while getting up through left means we have challenges and may not victorious.

Now I am suggesting my son to get out on the right side, the reason which i am giving him as a tradition that we follow. Till day, I have n't read many scientific publication why we need to follow this approach.



But came across many printed books that suggest it is because of some magnetic field orientation. that start from left to right. Anyway, in my experience the days will be becoming auspicious if we have "RIGHT" mind set. Did sides does matter, if we have right mind set?
