Mo sa gra:
As a newbie and a medical professional, I look at these photos of people meditating and wonder about it. I wonder about hours or days in such a position.
Isn't there a major risk for deep vein thrombosis? Are there reports of dvt in meditators?
I did a search on medscape and came up with
this small but interesting study. It doesn't give a definitive answer to your question (or the experimenters' questions), but it does suggest:
1. Meditation may improve left ventricle ejection compared to control (relaxation).
2. " " arterial elasticity " "
3. ...reduced peripheral resistance...
I honestly don't understand the statistical maneuvers they describe, and can't say for sure what the outcomes mean for DVT, but it suggests a hyptothesis for meditation reducing cardiovascular risks in general. Thought it might interest you.
