Know which direction is best for sleeping, your head direction while sleeping, the bed position as per vastu and also the best sleeping position to have a restful sleep
Ayurveda’s Triad of Health includes Aahar (Diet), Vihar (Balanced Living), and Nidra (Sleep).
Ayurveda and Vastu concur on sleep direction:
South-North: Sleep with the head towards the south and feet towards north.
East-West: East is a good direction too; sleep with the head towards the east and feet towards west.
Avoid sleeping with the head towards the west
Never sleep with the head towards the north.
North
While finding our true north (the north star has always been used for navigation) is spiritually and navigationally sound, north-facing sleep is not recommended at all, as it can cause issues with blood circulation, increased stress, physical and psychiatric issues, and insomnia. (The only exception is for yogis that want to practice lucid dreaming and astral travel, and I haven’t met any such yogis--I would absolutely recommend that yoga maya be avoided). Dr Vasant Lad says, “Only dead people sleep pointing north.” Indeed, the Hindu custom is to arrange a corpse with the head pointing north till the body is cremated, because the belief is that that is the route for the soul to exit the body, as Lord Ganesh’s myth suggests.
East
Sleeping with your head towards the East is supposed to be great for everyone, particularly students, because it enhances memory, improves concentration, and is good for overall health. The sun rises in the east, and it is considered a direction of positive waves and force of action. It makes a person feel rejuvenated and energized. It is also supposed to be good for meditation and spiritual pursuits. Vastu consultants often advise that kid’s beds be head-to-the-East and feet-to-the-West in direction. East-West sleep enhances creativity, is good for conception, and balances all three Doshas (Vata, Pitta and Kapha humors). Studies have shown that people who sleep in this direction have shorter REM sleep cycles and eye movement (compared to north-south sleep), implying fewer dreams and a more sound sleep.
West
Sleeping west to east is not advised. There are some who suggest that it increases Rajas, or ambition, and restlessness, but there are better ways to do that; some even consider it to be a neutral sleeping position. However, according to Vastu, sleeping with one’s head to the west can lead to restless and disturbed sleep, nightmares, and a tendency towards violence. SouthIf one goes by the theory of magnets, a mutual attraction between the negative south and positive head creates harmony in sleep. According to mythology, south is the direction of Lord Yama, and promotes heavy, deep sleep, like the restorative sleep of death. Vastu practitioners consider this to be the best type of sleep for health, lowering blood pressure and promoting positive energy, wealth, prosperity, and harmony.
