Practise legs-up-the-wall (Viparita Karani) properly: wall distance, entry, exit and what studies say about eye pressure, even where they disagree.
Is "legs up the wall" really an inversion, and is it safe? The honest answer: It is the mildest inversion there is, but not a free pass for everyone. In Viparita Karani ("inverted action") you lie on your back with your legs resting vertically against the wall. Your legs sit higher than your heart, your head stays on the floor. It is the posture many know as a "post-workout rest".
The eye question is interesting because the studies do not agree. In a study of 10 glaucoma patients and 10 healthy people, eye pressure in this pose rose from about 17 to about 21 mmHg after 2 minutes and fell back to baseline within 2 minutes of sitting up [1]. That is more than lying flat, but clearly less than in the forward bend (about 26 to 27 mmHg) or downward dog (about 28 to 29 mmHg) [1]. A second study with 25 healthy people and 25 glaucoma patients measured only +1.6 mmHg in "legs up" after 90 seconds in the healthy (+2.8 in glaucoma), versus +16.5 mmHg in downward dog [2]. A third study even found a drop in pressure after 30 seconds of legs up the wall [3].
How hard is the pose? Beginner-friendly. The build-up is less "holding" than "letting go".
Sit sideways to the wall, hips close to the wall. If the back of your legs is stiff, move a few centimetres away: the legs may be slightly bent.
Roll onto your back and place your legs on the wall. Your seat is near the wall, the hips on the floor. The head stays down.
Milestone: You lie for 2 minutes, legs feel light, no tingling.
If the lower back does not touch the floor, put a folded blanket under the pelvis. That is comfort, not a must.
Stay for 3 to 5 minutes, arms at your sides, palms up. Breathe calmly and deeply into the belly. In the studies the pose was held for only 30 to 120 seconds [1][2][3]; staying longer is practice standard, not evidence-based.
Milestone to move on: 3 minutes without dizziness, tingling or pressure in the head. By the way, this is also the entry test for shoulder stand.
Bend your knees, roll to your side, stay for 1 minute and sit up slowly. Do not stand up abruptly or you get dizzy easily.
Eye pressure is the main topic with inversions. A review of 76 published case reports found pre-existing conditions in ten cases, mainly glaucoma and osteopenia, and advises glaucoma patients to avoid inversions [4]. Whether the small pressure rises (legs up the wall about 1.6 to 4 mmHg [1][2]) matter for glaucoma progression is open. The study authors call for further research on this [1], the second says the extent remains unclear [2], and the study with the pressure drop describes only healthy practitioners [3].
If you have retinal problems, very high blood pressure or heart complaints, clear the pose medically. On blood pressure I only read about healthy practitioners, whose pulse and blood pressure did not change after 30 seconds [3]. This guide explains and motivates; it does not replace supervised training or medical advice.
Set your wall distance by the back of your legs, not by the photo. If you force your legs to stay vertical, you are practising a stretch of the hamstrings, not relaxation. Better move 10 to 20 centimetres away and keep the knees soft: then the wall carries the weight and you can truly let go. Practice trick: if you do not feel calmer after 3 minutes, the pose was too strenuous.
To start, 3 to 5 minutes, as is also customary as a preparation for shoulder stand. In measurement studies the pose was held for only 30 to 120 seconds [1][2][3]; longer times are practice standard and not evidence-based.
Yes, but a mild one: the legs are higher than the heart, the head stays on the floor. Eye pressure rose less than in forward bend or downward dog, by about 4 mmHg in one study [1] and by about 1.6 mmHg in another [2].
A review advises glaucoma patients to avoid inversions [4]. In two studies the pressure rose in glaucoma patients similarly to healthy people [1][2]. Whether this increases glaucoma progression is unresolved. Clear the pose with your eye doctor.
I read no reliable study on this. Many practitioners find the pose relaxing; that is experience, not evidence. With persistently swollen legs, have the cause checked medically.
