How the Body and Subconscious Process Collective Shock

After public acts of violence or collective shock, many people notice subtle but persistent changes in their body. Heightened alertness. Difficulty settling. A sense of unease that does not fully resolve, as life continues within a newly altered sense of safety.

What often follows is a quiet confusion: Why do I feel this way when nothing happened to me?

The answer is not psychological in the way we usually mean it. It is physiological.

When safety is disrupted in a shared or familiar environment, the nervous system responds through proximity, identification, and repetition. The body protects first and analyses later. It does not ask whether you were present. It asks whether the environment still feels predictable and safe. When it does not, protective responses activate.

For some, this response looks like hypervigilance — scanning rooms, startling easily, feeling unable to relax. For others, it moves toward withdrawal — numbness, heaviness, disconnection. These are not signs of weakness. They are organised survival states.

What helps is not forcing calm or trying to “move on,” but working directly with how the nervous system restores safety.

The first shift begins by giving the body evidence of the present moment. Simple physical orientation — noticing contact with the ground, the weight of the body, the support of a chair — signals to the nervous system that it is here, not in the imagined future. This alone often reduces internal urgency.

From there, regulation strengthens through rhythm. Slowing the exhale, introducing gentle repetitive movement, or using sound and vibration helps the system regain predictability. Rhythm communicates stability long before thought does.

Equally important is allowing the senses to register safety externally. Letting the eyes move around the room, noticing neutral or pleasant details, and recognising what is not a threat updates the brainstem in real time. This process is subtle, but it is foundational.

When these signals are offered consistently, many people notice improved sleep, reduced reactivity, and a greater sense of internal space. The nervous system begins to settle not because it is told to, but because it has been shown that it can.

However, when activation or shutdown persists, it often reflects patterns that predate the current event — stored physiological responses that were never fully resolved. In these cases, regulation practices alone are supportive but incomplete.

This is where trauma-informed, body-based therapeutic work becomes necessary. Work that does not rely on retelling or reliving, but on updating how the nervous system holds past experiences. When the body learns that a response is no longer required, it releases it naturally.

People often arrive saying, “I know I’m safe, but my body doesn’t.”That gap — between intellectual understanding and physiological experience — is precisely where this work lives.

If you are noticing that your system has not returned to baseline, that your responses feel out of proportion or unfamiliar, or that settling no longer happens on its own, it does not mean something is wrong with you. It means your nervous system is asking for a different kind of support.

Change does not come from pushing harder or waiting it out. It comes from working with the body in a way that restores safety at the level it was disrupted.

And when that happens, regulation follows.
