Psychosocial safety, in the moment

How Pressure Reps work

Once you hit Start, the clock runs while you fill in Regulate, Identify and Choose. No pausing — if time runs out, whatever you've written submits as is.

Why the limit: under real pressure, the part of your brain that thinks things through carefully is the first thing to go quiet. A rehearsed response survives that moment. An unrehearsed one doesn't get the processing time it needs, right when it needs it most.

You'll have 90 seconds once you start — no pausing.

Get Support

Some things need more than this app, or your workplace, can give you. That's not a gap in the training — some situations genuinely need a different kind of help. If any of this is close to what you're dealing with, here's where to go.

Policies, fairness, job security — if something feels unfair or inconsistent at a system level, that's a conversation for HR or your union, not something this app can fix.

Physical environment or safety — if the physical conditions of your job are the problem, report it through your normal WHS channel.

Family and domestic violence — if this is about your safety at home, please use one of the services above. This isn't a workplace issue to route through a training app.

🧘 CALM Regulation Tools

Practical techniques to reset your nervous system before you respond

C — Control your state

Box Breathing

A technique used by military, surgeons, and elite athletes to manually regulate the autonomic nervous system. Equal counts of inhale, hold, exhale, hold create a "box" that slows your heart rate and clears cortisol from the prefrontal cortex — restoring clear thinking in 60–90 seconds.

Ready
Press Start
4 rounds recommended
1
Inhale through your nose 4 sec
Breathe in slowly and steadily. Feel your chest and belly expand.
2
Hold 4 sec
Hold the breath without strain. Relax your shoulders.
3
Exhale through your mouth 4 sec
Let air out slowly and completely. Notice your body soften.
4
Hold 4 sec
Rest before the next inhale. Repeat 4 rounds minimum.
Use this when
  • You feel your heart rate rising before a difficult conversation
  • You're about to walk into a high-stakes meeting or presentation
  • You've just received a sharp or unexpected message and want to respond, not react
  • You're in a meeting and feel yourself getting activated
C — Control your state

Physiological Sigh

The fastest known method to reduce physiological arousal — endorsed by Stanford neuroscientist Andrew Huberman. A double inhale followed by a long exhale deflates the alveoli in your lungs that collapse under stress, offloading CO₂ rapidly and triggering the parasympathetic brake on your heart. One cycle takes under 10 seconds and works immediately.

1
First inhale through your nose ~2 sec
Take a full, deep breath in through your nose until your lungs feel mostly full.
2
Second short sniff ~1 sec
Without exhaling, take one more short sniff through your nose to top up your lungs completely. This is the key step.
3
Long slow exhale through your mouth ~6 sec
Let all the air out slowly and fully through your mouth. You should feel a noticeable drop in activation.
4
Repeat 1–3 times if needed
One cycle is often enough. Two or three brings most people to a noticeably calmer baseline.
Use this when
  • You're in the room and feel suddenly activated — it's nearly invisible
  • You've just heard something that triggered a strong emotional response
  • You need to recover quickly during a meeting, not after it
  • Box breathing isn't practical because someone is watching or waiting
M — Manage the moment

5-4-3-2-1 Grounding

A sensory awareness technique that interrupts the stress-thought loop by redirecting your attention to the present moment. When threat circuitry fires, the brain narrows attention to the perceived threat. Grounding deliberately broadens attention back to your physical environment — breaking the activation cycle and restoring access to the prefrontal cortex where your best decisions are made.

5
👁 Name 5 things you can SEE
Look around and name five things you can see right now. Be specific — not just "a chair" but "a grey chair with a scratched leg."
4
✋ Notice 4 things you can TOUCH
Feel the texture of four physical things — your clothing, the chair, a desk surface. Notice temperature, texture, pressure.
3
👂 Identify 3 things you can HEAR
Listen actively for three distinct sounds — air conditioning, distant voices, your own breathing.
2
👃 Notice 2 things you can SMELL
Even faint smells count — paper, coffee, your own clothing, the air itself.
1
👅 Notice 1 thing you can TASTE
Any taste currently present — even just the neutral taste of your mouth.
Use this when
  • Your mind is racing and you can't slow your thinking down
  • You're ruminating on a conversation or anticipating a threat
  • You feel disconnected or overwhelmed and can't access your usual thinking
  • You have 60–90 seconds before you need to re-engage with a difficult situation
