So you’ve been told that your psoas muscle is tight and it needs to be stretched.

Certainly this is easy enough to do with proper psoas stretching techniques during the daytime, but is it possible to do at night while sleeping?

Sure, but it may not be a good idea.  Let’s dive into this a bit more.

Is it possible to stretch the psoas while sleeping?

The psoas muscle is a hip flexor, so stretching it means placing it into its lengthened position, which is in extension.

The best example of this is the Thomas Test:

How To Stretch Psoas While Sleeping

As you can see the upper thigh needs to move into extension, which is moving in the direction behind you.  This is not the only thing you have to pay attention to.  The lower spine needs to be in a stable position, which is either a neutral curvature, OR flat on the table in order to allow for a full psoas muscle stretch.

Now, imagine yourself having to be in this type of position in bed.  Sure its possible to maintain this position while awake, but at night?

No way.  

And even if you figured out a way to rig this setup so that you could fall asleep in it, your leg would very likely fall asleep in that position.  It would be very uncomfortable.

What works better?

The better option is to sleep in a comfortable position which allows the greatest relief in order to get a good nights sleep, and address chronic psoas tension issues in the daytime!
