Nina: Yesterday, Baxter gave us a little background on blood pressure (see So, what is blood pressure, anyway?). I thought today you could talk a bit more about the relationship between blood pressure and yoga.
Shari: First some more background! Of particular importance is the effect of our baroreceptors on blood pressure. Baroreceptors are stretch receptors that found in the major arteries, and they are activated when our arteries are over- or under-pressured by blood flow. This in turn changes our heart rate and arterial diameters. Baroreceptors are found abundantly in the carotid sinuses, the carotid arteries of the neck and the aortic arch of the heart.

Nina: For all of us overstressed folks, decreasing blood pressure is a good thing. And I’m betting yoga can help with this....
Shari: Absolutely. Research has shown that both forward bends and inversions affect the cardiac baroreceptors, ultimately causing a decrease in blood pressure and heart rate! Inversions and forward bends also increase baroreceptor sensitivity toward the fluid dynamic changes. So both forward bends and supported inversions are both recommended for reducing blood pressure.
Nina: That explains why both forward bends and supported inversions are considered calming poses. I certainly use both in my home practice for stress reduction. Do you have any favorite poses for lowering blood pressure?
Shari: I like supported Setubanda Sarvangasana (Bridge pose, with straight legs), perhaps with a head wrap. I also like Viparita Karani (Legs Up the Wall pose) with a head wrap. When the going gets rough, these are my “comfort poses.”
Nina: I also love Legs Up the Wall pose. And supported Child's pose is a good example of a forward bend that is very comforting—just thinking about it makes me relax. And we’ll definitely have to talk about the head wrap sometime soon!
