Free Nervous System Reset Guide: 5 Techniques

Attention on your heart. Breathe five seconds in, five seconds out. Then bring up a genuine feeling — appreciation, care, whatever's real for you. That second step is what turns it from breathing into the full Quick Coherence Technique. HeartMath's own research backs this up: your heart rhythm shifts from the erratic, spiky pattern of stress to something smooth and coherent. You can see it on a screen. Not just feel it.

Two short inhales through the nose, no exhale in between. Then one long, slow exhale out the mouth. Stanford researchers (Balban et al., 2023) tested this against box breathing and a couple of other styles — this one calmed people down faster than all of them. One to three breaths. That's it.

Hum, low and steady, on the exhale — lips closed, feel it vibrate through your chest and throat. Your vagus nerve runs straight through the muscles in your larynx, so humming, gargling, even chanting in the shower — it all talks directly to that nerve. Stephen Porges, the researcher behind Polyvagal Theory, backs this one in.

Five things you can see. Four you can hear. Three you can feel. Two you can smell. One you can taste. Just notice them — don't judge them, don't analyse them. This one's different to the other four. It's not for when you're wired. It's for when you've gone numb or checked out. Sensory grounding is core mindfulness work — one of the practices Andy teaches as an IMMA-accredited trainer — and it's exactly how trauma-informed practitioners bring a shut-down nervous system gently back online.

Notice what you're feeling. Don't fix it, don't argue with it yet — just notice. Then name it specifically. Not "I'm stressed." Try "I'm feeling anxious about how that meeting went." That's mindfulness, plain and simple — noticing before naming. UCLA's Matthew Lieberman scanned people's brains doing exactly this and found something real: naming the feeling precisely actually quietens the amygdala, your brain's alarm bell. The words aren't just describing what's happening in your body. They're changing it.
