I do this sometimes, lol. It’s actually the closest thing I have to a technique when it comes to dealing with reconciliation.
Psychosomatics have an “as above, so below” dynamic, where the physical (above) and the subconscious/emotional (below) reflect and influence each other.
When you’re subconscious/emotionally stressed, your body can reflect it. Your breathing won’t be as relaxed, your muscles might be tense, and the oxygen supply to your brain decreases.
You can hack this “as above, so below” feedback loop by consciously relaxing and loosening your body through deepening your breath (breathe to your balls throughout your whole body and let the oxygen flow, lol). Think of this as also relaxing your subconscious/emotional" body" which grounds the processes occurring in it allowing things to flow and move more smoothly. It also relaxes your nervous system.
I’ve seen people who have been stressed out for very long periods of time do this, and they say it’s like a flood of relief. It’s because their body has been stuck in a high-alert state with restricted oxygen flow and an overstimulated nervous system for so long, that the sudden shift is almost euphoric.
