Vaasthu Sastra tells that one should always sleep with head pointing either, East or South.
Sleeping with head pointing East, and legs pointing west will make you healthier, both mentally and physically - basically ayussu, arogyam and sowkyam
Sleeping with head pointing South, and legs pointing north will give you wealth and prosperity.
Whatever, never sleep with head pointing North. This will have an adverse effect on health.
It is advisable to have the children sleeping with head towards East all the time.
