Nervous System Regulation

Bethany Sherman, LMHC

These practices are offered as between-session support. Some of them, particularly pendulation and havening, involve sustained attention to body sensation or touch, and may feel activating before they feel settling. If a practice ever feels like too much, stop, orient to your surroundings, and bring what came up into our next session. You don't have to push through discomfort alone, and no single technique here is the right fit for every moment or every nervous system.

Fast-Acting Resets

Under two minutes, wherever you are.

1
Box Breathing
Breathe in slowly for 4 counts. Hold for 4. Breathe out for 4. Hold for 4. Repeat for 4 to 6 cycles. The extended exhale and hold lengthen the time your body spends breathing slowly, which shifts your autonomic nervous system away from the sympathetic, fight-or-flight activation of stress and toward its calmer, parasympathetic side. Useful before a stressful conversation, when anxiety is climbing, or as a quick reset between tasks.
2
Physiological Sigh
Take two quick inhales through your nose (the second one shorter, as if topping off a full breath), then release one long, slow exhale through your mouth. Repeat for 1 to 3 cycles. In a 2023 Stanford study comparing several breathing patterns, this one produced the fastest drop in respiratory rate and the largest improvement in mood after a single five-minute session. If you need something even faster, briefly splashing cold water on your face or holding an ice cube to your wrist can trigger a similar rapid shift through the body's dive reflex.
3
Butterfly Hug
Cross your arms over your chest, resting each hand on the opposite upper arm or shoulder. Alternate gentle taps, left hand then right, in a slow, steady rhythm, about 8 to 12 taps per side. Pair it with slow breathing or a calming phrase if that helps. This is a form of bilateral stimulation, originally developed for community crisis response and now used widely alongside EMDR. It can be done seated or standing, without anyone else noticing.

Body-Based Regulation

Slower practices that take more time and attention to learn.

1
Progressive Muscle Relaxation
Starting with your feet, tense a muscle group firmly for 5 to 10 seconds, then release all at once and notice the contrast for 20 to 30 seconds before moving to the next group: calves, thighs, abdomen, hands, arms, shoulders, face. This is one of the most consistently researched relaxation techniques available, with decades of evidence behind its use for anxiety, stress, and sleep. It takes practice to feel the difference between tension and release clearly, so don't expect it to feel dramatic the first few times.
2
Orienting
Slowly turn your head and eyes, taking in the details of the room around you: colors, shapes, light, objects you hadn't noticed. Name a few of them, out loud or silently. This isn't distraction; it's letting your nervous system register, through your senses, that you are here, in this room, and that right now nothing in it is a threat. It's often useful for opening or closing a harder piece of work, or anytime you notice yourself feeling far away or frozen.
3
Pendulation
Bring your attention to a place in your body holding some activation or discomfort: tightness, heat, an unsettled feeling. Stay with it for a few breaths, only as long as it feels tolerable. Then deliberately shift your attention to a place of relative ease: your feet on the floor, your hands resting, a part of your body that feels neutral or calm. Rest there for a few breaths before checking back in with the activation, if it feels right to. This back-and-forth movement is how Peter Levine described the nervous system's natural rhythm between contraction and expansion. Practicing it in small doses builds capacity to be with difficult sensation without being overwhelmed by it. If the activation grows rather than settles, stop and bring it to session rather than pushing through alone.
4
Havening
Cross your arms and stroke each hand slowly from shoulder to elbow, then rub your palms together, then stroke your palms down from your forehead to your cheeks, all slowly and gently. While you do, occupy your mind with something neutral: counting backward from 20, humming a tune, picturing a familiar walk. Continue for 2 to 3 minutes. Havening pairs self-soothing touch with mental distraction. It's offered here as one option among several, not as a primary treatment. Its research base is much thinner than the other practices on this page. See the note below.

Broader Supports

Not in-the-moment techniques: the standing conditions that make regulation easier overall.

Regular Exercise
Aerobic exercise doesn't just burn off stress hormones in the moment. Over time, it recalibrates how your HPA axis (the system that governs your cortisol response) recovers after a stressor. A single workout raises cortisol temporarily, but a body that exercises regularly gets more efficient at shutting that response back down. Research specific to PTSD populations has found that regular aerobic exercise restores healthier cortisol regulation and reduces markers of chronic stress activation. Consistency matters more than intensity here. Three or four moderate sessions a week does more for your baseline than one hard workout.
Connection With Trusted People
Your nervous system doesn't only regulate on its own. It regulates in relationship. Decades of research on social buffering show that the presence of someone you trust measurably lowers your body's stress response: slower heart rate, blunted cortisol, less neural threat activation, compared to facing the same stressor alone. This is part of why talking something through with a person who feels safe can shift your state in a way a solo coping skill sometimes can't, and part of why what happens between us in session matters as much as any individual technique on this page.

Sources & Evidence Notes

What's well-established, what's more preliminary, and where each technique comes from. Click a technique to expand.

Well-established Established model, less RCT evidence Limited / anecdotal evidence
Box Breathing Established model, less RCT evidence

Slow, extended-exhale breathing is well supported as a way to shift the body from sympathetic activation toward parasympathetic calming in general. The specific 4-4-4-4 protocol has less dedicated research than other ratios, and at least one controlled study found it performed less well than six-breaths-per-minute pacing for post-exercise recovery.

Physiological Sigh Well-established

A randomized, controlled Stanford study found this pattern (cyclic sighing with an exhale emphasis) produced greater improvements in mood and larger reductions in respiratory rate than mindfulness meditation or box breathing, with effects measurable after a single session.

Butterfly Hug Well-established

Developed by EMDR therapist Lucina Artigas for community crisis response, and now a standard self-administered bilateral stimulation tool taught within EMDR therapy. Preliminary neuroimaging work suggests measurable change in amygdala and prefrontal activity during its use, though that finding comes from a small, early study and should be treated as suggestive rather than conclusive.

Progressive Muscle Relaxation Well-established

Originally developed by Edmund Jacobson in 1938. Among the most heavily studied relaxation techniques, with multiple systematic reviews and meta-analyses supporting medium-to-large effects on anxiety and sleep quality across dozens of trials.

Orienting Established model, less RCT evidence

The orienting response is well documented in neuroscience as a reflexive shift of attention toward environmental stimuli. Its clinical use as a grounding technique comes primarily from Somatic Experiencing's theoretical and case-based literature rather than randomized controlled trials, though it's widely taught across trauma-treatment approaches.

Pendulation Established model, less RCT evidence

Pendulation is a core concept within Somatic Experiencing, describing the nervous system's natural oscillation between activation and settling. It's supported by clinical case literature and the broader research on titrating exposure to arousal in trauma treatment, but has fewer dedicated randomized controlled trials than exposure-based or cognitive approaches. This is a good one to practice with therapist support before relying on it alone with strong activation.

Havening Limited / anecdotal evidence

Developed by Ronald Ruden. Independent reviewers have consistently noted a lack of peer-reviewed, controlled outcome research on Havening specifically: a search of the published literature turns up largely case reports and practitioner-reported outcomes rather than randomized trials. It's included here as a gentle, self-soothing touch practice, not as a substitute for trauma-focused treatments with a stronger evidence base, such as EMDR or prolonged exposure.

Regular Exercise Well-established

One of the more mechanistically well-understood entries on this page. Regular aerobic exercise improves how efficiently the HPA axis shuts down cortisol release after a stressor, and this effect has been specifically documented in PTSD populations, alongside reductions in oxidative stress markers tied to chronic activation.

Connection With Trusted People Well-established

Social buffering is one of the longer-standing, more replicated findings in stress physiology. The presence of a trusted attachment figure has repeatedly been shown to reduce cardiovascular and neuroendocrine stress reactivity compared to facing the same stressor alone or with a stranger, across both human and animal studies.
