How to Decompress Your Spine, Ranked by the Evidence

How to Decompress Your Spine at Home, by Evidence and Risk

These are the four main ways to decompress your lower back without equipment beyond a bar or a table, in order: the most measured and lowest risk first.

1. Lie Down and Take the Load Off

The simplest option is also the best studied. In the 1985 stature study, resting in Fowler’s position, a supported reclined rest position used in these labs, regained height faster than recovering while standing (Tyrrell, 1985). In a 2009 study of 21 young adults, ten minutes lying on the back with the trunk flexed significantly increased spine height after a period of sitting (Owens, 2009).

In practice: lie on your back on the floor or a firm bed, bend your knees, rest your lower legs on a chair or cushions if that is comfortable, and stay there for 10 to 20 minutes. It costs nothing, and when you are done, roll onto your side before getting up rather than sitting straight up. Answering the common question “how can I decompress my spine while lying in bed?”: this is it.

2. Gentle Back Extension, Face Down or Over a Support

The second option has the most detailed numbers. In ten people lying face down in controlled back extension, time mattered most for regaining height, a bigger angle helped for a given time, and the best combination tested was 20 degrees for 20 minutes; the authors described it as a way “to unload temporarily the spine” (Magnusson, 1996). In the 2009 study, ten minutes of face-down extension worked as well as the flexed position on the back (Owens, 2009).

You can also do it lying on your back. In ten healthy men, ten minutes over an inflatable cushion under the lower spine produced a height gain in every subject, and MRI showed the front of each disc getting taller (Kourtis, 2004). A rolled towel or a firm pillow under the lower back is the home version. If extension causes leg pain or numbness, stop: that position is not for you.

3. Hanging From a Bar

Hanging by the hands from a pull-up bar uses your legs and hips as the weight that stretches the spine. It also asks a lot of your grip and shoulders, and in our search of Europe PMC we found no study that measured spine height or disc space during a dead hang the way the studies above did. What hanging can and can’t do, and how to build up to it safely, is on our page about dead hang benefits.

4. Inversion

Inversion is the most direct way to stretch the spine with gravity, and it is the one with real measurements. X-rays of 15 healthy men after ten minutes fully inverted showed more separation at every lumbar level measured (Kane, 1985). In 20 people with chronic low back pain, inverted traction widened the lower lumbar disc spaces by 0.3 to 4.0 mm. The same study recorded blood pressure rising by about 17 mmHg on average while inverted, and persistent headaches or blurred vision in three patients each; the authors said home use should be under medical supervision (Gianakopoulos, 1985).

The catch is how long it lasts. After a workout, 20 minutes of inversion added 5.18 mm of stature against 0.76 mm for standing, but 40 minutes on their feet afterwards took back 4.07 mm, and by 30 minutes the difference was no longer significant. The authors’ conclusion: the effects of inversion “are short-lasting” (Boocock, 1990). What inversion trials found for pain is on our page about inversion table benefits, and setup, angle and session length are covered in how to use an inversion table.

Spinal Decompression Exercises: What the Guidelines Recommend

Search for “spinal decompression exercises” and you get dozens of routines with set numbers of seconds and repetitions. None of the clinical guidelines we read uses the term.

Exercise Is Recommended, in General

NICE tells clinicians to encourage people with low back pain to continue normal activities, to consider a group exercise program (biomechanical, aerobic, mind-body or a mix) for an episode or flare-up, and to use manual therapy only alongside exercise (NICE, 2016). The American College of Physicians’ guideline notes that most acute low back pain improves over time regardless of treatment, and for chronic pain recommends starting with options such as exercise, tai chi, yoga, motor control exercise or progressive relaxation (Qaseem, 2017).

Does Walking Decompress Your Spine?

Not in the measured sense. In seven healthy men walking on a treadmill for 30 minutes, total spinal length and the lumbar segment both decreased over time (Watson, 2012). Any upright activity loads the spine. Running in deep water, where the body is supported, cut that loss: 2.92 mm against 4.59 mm on a treadmill in 14 runners (Dowzer, 1998).

That is not an argument against walking. Staying active is what the guidelines ask for. It just means walking is exercise, and lying down is the unloading.

Building a Routine Without Invented Numbers

A sensible home routine follows from the above: stay active during the day, and use 10 to 20 minutes of lying on your back or face down in gentle extension when your back feels compressed, the range the studies tested. For a structured exercise plan for a back condition, a physical therapist can choose the type of exercise, which is what NICE asks for when it says to take “specific needs, preferences and capabilities” into account (NICE, 2016). If you already own a table, the step-by-step stretches and core moves on it are on our page of inversion table exercises for beginners.

Who Should Not Try These Methods

Lying down is safe for almost everyone. The further you go toward hanging and inversion, the longer the list of people who should check with a doctor first.

Inversion and Head-Down Positions

Two minutes of inversion raised blood pressure significantly in 60 healthy young women (Haskvitz, 1986), and five minutes fully inverted roughly doubled eye pressure, in healthy eyes and in eyes with glaucoma (Weinreb, 1984). Teeter tells users not to invert until a licensed physician approves if they have high blood pressure, heart conditions, glaucoma, retinal detachment, osteoporosis, hernias, pregnancy or several other conditions (Teeter). Our page on who should not use an inversion table goes through each one with the evidence.

Falls Are the Other Risk

Falling off an inversion table works like a shallow-water diving injury, onto the top of the head; a report of three cases describes cervical spinal cord injuries from falls of one or two feet (Jung, 2021). If inversion isn’t for you, there are other ways to take load off the spine, compared in our guide to inversion table alternatives.
