Eka Pada Sirsasana, Eka Pada Greevasana, One-Leg-Behind-Head Pose, One-Foot-Behind-Head Pose
The description of this posture is short and quick while actually practicing it may take some time:
Sit in Dandasana with your legs stretched out in front of you and your back straight. Hold your hand in front of your nose to check which of your nostrils is active. Grab the ankle of the active side (if your left nostril is active take the left ankle, if it is your right nostril, take the right ankle), bend your knee with inhalation, bring it over your head and place it slowly with exhalation on your neck.
Smile and breathe!
This yoga pose increases the blood flow especially in your back and improves your hemoglobin levels. With the increased blood flow toxins are removed that accumulate if the blood flow is slow or interrupted. Eka Pada Sirsana helps people who suffer from anemia and also from nervous trembling.
Eka Pada Sirsasana is an intensive work for your body that activates fire and thus helps your body to digest food quickly.
And of course you can imagine that it increases your flexibility.
As soon as you are able to actually bring your leg behind your head, you should concentrate on your breath and make it slow and steady. Try to relax in the posture while straightening your spine as far as possible.
Don’t despair if you are not able to get your leg up in the beginning! This is a yoga exercise that needs practice and patience!
If you have mastered it and would like to go further, you can either begin practicing Dwi Pada Sirsasana or place your hands next to your body and lift your body up with the other leg stretched out in front of you.
Whoever has problems or injuries in the spine, the back or in knees and hips should not perform this yoga posture. If there is doubt or discomfort, please consult your doctor and let your yoga teacher know about it. Do not force yourself into this position as it can lead to overstretch and injuries.
