I found this nice little illustration of baroreceptors that I'm excited to share with you. Okay, I admit it, I'm a little obsessed with baroreceptors. But that's because ever since I found out how our baroreceptors help regulate our blood pressure and I understood how we can use this aspect of our anatomy to switch our nervous systems from fight or flight to relaxation mode, I've not only included supported inverted poses in my practice on a regular basis but I've been on a mission to spread the word. Using supported inverted poses for stress management is one of easiest ways—at least for me—to calm yourself down because all you have to do is set yourself in the pose and stay there for a while. The shape of the pose itself causes the baroreceptors to work their magic.
And in the wall of your aortic arch (just above your heart).
Aortic Arch |
In an inverted pose, your heart is higher than your head, the opposite of its position when you are upright. With your heart higher than your head, gravity causes more blood to flow in the direction of your head, creating more pressure than usual on your carotid sinus and aortic arch. As the arterial pressure is increased, your baroreceptors are stretched and signals are transmitted to your central nervous system as if your blood pressure was high throughout your body. Feedback signals are then sent back to your body to reduce the arterial pressure, slowing your heart rate, relaxing your blood vessels, and releasing hormones that decrease adrenaline production. This automatically switches your body to relaxation mode.
Any yoga pose where your heart is above your head is considered to be an inversion. Inverted yoga poses include full inversions, such as Headstand and Shoulderstand, where your heart is directly over your head and the rest of your body is also fully inverted. Partial inversions, such as Downward-Facing Dog pose and Standing Forward Bend, where your heart is less directly over your head and your legs are either not fully or not at all inverted, are also considered inverted poses and will have similar calming effects. As long as you are warm, quiet, and comfortable in the inverted pose, all you have to do is let the baroreceptors work their magic. Naturally, supported versions of the poses (such as Shoulderstand with a chair or Bridge pose on blankets) are more relaxing than the versions of poses in which you must support yourself, so if you’re practicing inversions for stress reduction, choose the supported versions. See Just in Time for the Holidays: Inverted Poses for a complete list of the inverted poses.
Caution: Inverted poses may be unsafe for those with certain medical conditions (see here).
