Query on Shirshasana
Question
Blood vessels in the brain are of microsize. When one sleeps laying his head towards the North, blood flows towards the head. Microsized blood vessels in the head cannot handle the rise in flow - this is one of several reasons given to why one should not sleep with his head facing the North.
In sheershaasana there is a huge rush in blood volume towards head. Its always bothered me whether itll do any. I do it for 68 mins. I feel groggy sometimes. Especially if I do it when I am having a headache, it worsens. Please explain to me a bit about this contradiction(that on one hand 'sheershasana' has immense benefits. And on the other hand, blood flow towards head may even rupture few blood vessels, which we may even not realise, but it certainly harms by ensuing dullness and intermittent dizziness).
Can I do 'sheershasana' as long as I feel comfortable (like 15-30 mins)? Or is there a duration limit beyond which I shouldn't do?
Please help me overcome this practical dilemma.
Answer
1. Yoga is a perfect science. It is to be done right, under proper guidance from an adept.
2. One should start holding an Asana pose for a few seconds only. Gradually, the duration can be increased to the point of comfort and not more.
A duration of 6 minutes is excessive and unnecessary.
