Does this action protect the Sacral Chakra?

[Xelador]

I used to be somewhat military-mind orientated, and would often have my hands behind my back like shown in the image.

I always felt like it gave me some sort of protection from others, but never understood it.

Ever since I went through a psychotic break a few years ago, it changed my body language and I stopped doing so and honestly feel exposed in a sense. Does body language hold any significance to chakra points?

The at ease stance! I believe its just slightly empowering than doing nothing with ones hands for short periods because it is an active gesture, compared with a normal hands at sides posture. Its better than folded arms becausd it does not look so defensive in what we judge in modern day becauss of how our culture has guided us to interpret. This posture also shows off the torso and abs areas and would be empowering for those that are fit, and uncomfortable for those who are not unless already in a comfort situation.

[Compendium]

It is a power stance that shows self confidence/dominance as opposed to having the arms crossed in front of the chest which is defensive, or the shoulders slumped forward which shows lack of confidence, or the hands in the pockets which is only done in casual settings among ppl others feel safe around.
