Sleep is to take the rest afforded by a suspension of voluntary bodily functions and the natural suspension, complete or partial, of consciousness; cease being awake. Physiologically, sleep is a complex process of restoration and renewal for the body. Generally when we sleep we don’t know which direction we need to place our head.The direction we sleep has a strong impact on our body.
When Parvathi created a boy from turmeric to guard her while she was taking bath.When Lord Shiva returned he find a stranger denying him access, and struck off the boy's head in rage. Parvati broke down in utter grief and to soothe her, Shiva sent out his squad (gana) to fetch the head of any sleeping being who was facing the north. The company found a sleeping elephant and brought back its severed head, which was then attached to the body of the boy. Hindus trust that sleeping in north direction will cause death. As per traditions South is the direction of Yama (God of death) we shouldn't keep feet in south and only a dead body must be placed in that position.
Now we may realize why the ancient people said, that our intellect improves by east facing head or house, and life lengthens with the head facing south.
The direction your head faces while sleeping has a strong effect on your physical and mental well-being. Head placement refers to the direction the top of your head points when lying down.
We are advised to avoid sleeping with our head to the north or west.
We all know that our planet has a magnetic pole stretched from north to south with the positive pole at the north and the negative pole at the south. Now, health scientists tell us that we too have a similar magnetic stretch with the positive pole at the head and the negative one at the feet.
It is common knowledge that like poles repel and unlike poles attract not only scientific but also in social spheres. When we lay our heads on the north side, the two positive sides repel each other and there is a struggle between the two.
Since the earth has a greater magnetic force, we are always the losers, and rise in the morning with headache or heaviness.
Head to East: Auspicious. Always make sure you put your head in the East direction as much as possible.
Avoid daytime sleep. Let the night food be light and early. Drink milk with honey.
Avoid reading serious or sensual literature straining the nerves. Repeat a few mantras to relax your mind before you sleep.
Head to South: Auspicious. The best position for sleeping is with the top of your head pointing to the south and feet pointing north.
Head to North or West:
Results: Dangerous. Never sleep with the top of your head pointing to the north and feet pointing to the south. Brings terrible dreams and disturbed sleep. You will feel miserable. Irritability, frustration and emotional instability will develop. It sucks your positive vibrations while you sleep. You will lose 50% of your willpower and your soul power will not increase while you sleep. Your physical and mental health will suffer.
North: it is in line with the earth's magnetic field and will create disturbance in human bodies which has high iron (hemoglobin) content and brings disease and west dulls the brain
When we lay our heads in the southern direction, there is mutual attraction and we wake up fit, fresh and free, unless afflicted by some illness.
We also know that our planet revolves itself from west to east, and sun's magnetic field enters earth from east side. This magnetic force enters our head if we lie with head on the east and exits through feet, promoting cool heads and warm feet as per the laws of magnetism and electricity. When the head is laid towards the west, cool feet and hot head -- result -- an unpleasant start for morning.
