Breathing for sensory overload

Why this helps

When sensory overload activates the nervous system's threat response, slow, deliberate breathing is one of the fastest ways to downregulate it. Extending the exhale activates the parasympathetic system, reducing heart rate and cortisol. For autistic people and those with sensory sensitivities, simple, low-effort breathing techniques that don't require focus on the body can be especially helpful — this guide keeps the steps minimal and predictable.

Practical steps

1. Find a slightly less stimulating position or space if possible — you do not need complete quiet.
2. Focus only on your exhale: breathe out slowly and fully, allowing the inhale to happen naturally.
3. Count silently to 4 or 6 on each exhale to give your mind a simple anchor.
4. Repeat for 10–15 breath cycles, staying only with the count — let everything else fade to background.
5. When you feel even slightly calmer, pause and notice the difference before returning to your environment.

Helpful tips

• If focusing on breathing itself feels uncomfortable, hum gently on the exhale — the vibration has a similar calming effect.
• Pair breathing with a grounding object (hold something textured or weighted) to reduce the cognitive load.
• Practice this technique when you are calm so it becomes automatic under stress.
• Nose breathing is generally more calming than mouth breathing; but use whichever feels natural to you.
