The Butterfly Hug Technique

A bilateral self-tapping exercise used in EMDR therapy and trauma care to reduce anxiety and restore a sense of safety.

The Butterfly Hug was developed by EMDR therapists Lucina Artigas and Ignacio Jarero in 1998, originally to support survivors of a hurricane in Mexico. It has since become one of the most widely used bilateral stimulation techniques in trauma therapy, used as preparation for EMDR processing and as a standalone regulation tool.

Unlike most calming techniques, the Butterfly Hug uses bilateral stimulation — alternating left-right tapping — to gently engage the same neurological pathways activated during EMDR. This cross-body movement helps the nervous system shift out of a stress response and into a calmer, more integrated state.

How to do it

Why it works

Bilateral stimulation — any alternating left-right sensory input — appears to reduce the emotional intensity of distressing material while keeping you connected to the present moment. The mechanism is not fully understood, but several theories point to activation of the brain's natural information processing system, similar to what happens during REM sleep.

In practice, bilateral stimulation tends to reduce physiological arousal (heart rate, muscle tension, breathing rate), soften the emotional charge of difficult thoughts or memories, and support integration across left and right hemispheres of the brain.

The Butterfly Hug specifically is valued because it is self-administered, requires no equipment, can be done discreetly in public, and involves physical self-contact — which adds a layer of self-soothing that pure audio or visual BLS tools do not.

When to use it

• Before or after a therapy session — to arrive regulated or return to baseline
• During anxiety or overwhelm — as a portable, immediate regulation tool
• After a distressing event — to process and settle before sleep
• As part of EMDR preparation — to strengthen a safe place or positive resource
• With children — simple enough for young people to use independently
• Between therapy sessions — as a between-session grounding practice

Stop if

The Butterfly Hug is a low-load technique safe for most people. However, stop and take a grounding break if you notice:

• Increased distress or a sense of things getting worse rather than better
• Intrusive images or memories surfacing unexpectedly
• Dissociation or feeling disconnected from your surroundings

If any of these occur, try 5-4-3-2-1 grounding or box breathing to return to baseline, and discuss what happened with your therapist.

Other grounding techniques

• 5-4-3-2-1 Grounding — sensory anchoring through the five senses
• Drop Anchor (ACT) — acknowledge your experience, connect with your body, engage with the world
• Temperature grounding — hold ice, splash cold water or press something warm against your skin
• Box breathing — a 4-4-4-4 breathing pattern that calms the nervous system
• Physiological sigh — a double inhale and long exhale for rapid stress relief
