If you've never heard of EMDR before, the name alone can raise an eyebrow. Eye Movement Desensitisation and Reprocessing sounds technical, even a little strange. And the idea that moving your eyes back and forth while thinking about a painful memory could help you heal might feel hard to believe.

But thousands of studies and decades of clinical practice say otherwise. EMDR is now recognised by the World Health Organisation (WHO), the American Psychological Association, and the UK's National Institute for Health and Care Excellence (NICE) as one of the most effective treatments available for trauma and PTSD.

Here's what you actually need to know — in plain language.

What Is EMDR?

EMDR is a structured therapy developed in the late 1980s by psychologist Dr Francine Shapiro. It was originally designed to reduce the distress associated with traumatic memories, and it does so through a process called bilateral stimulation — typically moving your eyes side to side, following the therapist's finger or a light bar, though tapping or audio tones can also be used.

Unlike traditional talking therapies, EMDR doesn't require you to describe your trauma in detail or spend months slowly unpacking your past. Instead, it works by stimulating your brain's natural healing process — a process that, in people who've experienced trauma, has become stuck.

Why Trauma Gets Stuck

To understand why EMDR works, it helps to understand what trauma does to the brain.

When something frightening or overwhelming happens, the brain's processing system can become overwhelmed. Instead of the memory being stored and filed away like most memories, it gets "frozen" — trapped in its original disturbing form, complete with the emotions, physical sensations, and beliefs that accompanied it at the time.

This is why trauma feels so present, even when it happened years ago. A smell, a sound, or a certain tone of voice can pull a person straight back into that frozen moment — because the nervous system genuinely hasn't processed the experience as being in the past yet.

Trauma isn't what happened to you. It's what happens inside you as a result of what happened to you. — Gabor Maté

How Bilateral Stimulation Helps

This is where EMDR gets interesting.

When you enter REM sleep, your eyes move rapidly back and forth. Researchers believe this natural bilateral movement helps the brain process and consolidate the day's experiences — including distressing ones. EMDR appears to activate a similar process while you're awake and in a safe, supported environment.

During EMDR, as you focus on a distressing memory while following the bilateral stimulation, something remarkable often happens: the memory gradually loses its emotional charge. It doesn't disappear — you still remember what happened — but it begins to feel like something that happened in the past, rather than something that's still happening now.

What Does an EMDR Session Look Like?

A typical EMDR treatment follows eight structured phases:

  1. History and treatment planning — We talk about what you've been through and identify the memories or issues to target.
  2. Preparation — I teach you grounding and stabilisation techniques so you always feel safe and in control.
  3. Assessment — We identify the specific image, negative belief, and body sensations associated with a target memory.
  4. Desensitisation — This is when the bilateral stimulation begins. You hold the memory lightly in mind while following my fingers (or another stimulus) back and forth.
  5. Installation — We reinforce a positive, realistic belief to replace the negative one.
  6. Body scan — We check for any remaining tension or discomfort held in the body.
  7. Closure — We bring you back to a calm, grounded state before the session ends.
  8. Reevaluation — In the next session, we review how you feel and what has shifted.

Sessions are usually 50–90 minutes, and most people find that processing continues gently in the days after a session — through dreams, new insights, or a gradual easing of distress.

Who Can Benefit from EMDR?

EMDR is particularly well-suited for:

It's also worth noting what EMDR isn't: it requires active engagement, and some processing can feel uncomfortable before it resolves. A skilled therapist will always move at your pace and will not push you into material before you feel ready.

How Many Sessions Does It Take?

This varies significantly from person to person and depends on the nature and complexity of what you've experienced.

A single, clearly-defined traumatic event — like a road accident or a one-off assault — may resolve in as few as 3–8 sessions. Complex or developmental trauma, especially from childhood, tends to require longer work, often 20 or more sessions over time.

That said, many people notice meaningful shifts within the first few sessions, which can itself be very encouraging when you've been struggling for a long time.

Is EMDR Right for You?

EMDR isn't the right fit for everyone, and that's completely okay. Some people prefer to work through their experiences primarily through conversation, and there are excellent trauma therapies that take a more verbal approach — like trauma-focused CBT or somatic work.

The best way to find out is to have an initial consultation. We'll talk about what you've been through, what you're hoping to achieve, and which approach feels right for you. There's no pressure, and no commitment required at that stage.

If you've been carrying a painful memory or a difficult period of your past that doesn't seem to ease with time — no matter how much you try to move forward — EMDR may be exactly what your nervous system needs to finally lay it to rest.
