Eye Movement Desensitization and Reprocessing (EMDR) is a therapeutic approach utilized to help individuals process and heal from psychological trauma. The process involves recalling distressing memories while simultaneously focusing on an external stimulus, often a rhythmic back-and-forth movement. This bilateral stimulation is designed to activate the brain’s natural healing mechanisms, allowing traumatic memories to be reprocessed and stored in a less emotionally charged way. A common query regarding potential physical reactions is whether EMDR therapy can result in headaches. This article examines the connection between this treatment method and the experience of head pain.
The Link Between EMDR and Headaches
EMDR therapy can cause headaches, which are a recognized, temporary side effect of the treatment process. This physical reaction is commonly reported by individuals following a session. Headaches resulting from EMDR are typically short-term, acute reactions that subside within a few hours or, at most, a couple of days. This discomfort is a transient response to the intense processing involved, not a permanent physical complication.
The majority of these incidents are consistent with tension headaches, characterized by mild to moderate pain that feels like a tight band around the head. Intense emotional and neurological activity can occasionally trigger a full-blown migraine in individuals predisposed to them. Experiencing a headache post-session is viewed by therapists as a sign that the brain has engaged in significant information processing.
Biological and Psychological Contributors
Head pain during or after an EMDR session stems from a combination of psychological exertion and physical mechanisms related to the therapy. Reprocessing traumatic memories requires intense focus and emotional engagement, leading to psychological stress. This rapid recall of distressing material often triggers emotional release, which can manifest physically as somatic symptoms, including head pain. The intense processing activity increases overall nervous system arousal, contributing to the physical discomfort.
A direct mechanical contributor is the ocular strain caused by the rapid, repetitive eye movements that define the procedure. Tracking the stimulus taxes the extraocular muscles surrounding the eye, leading to localized fatigue. This muscular fatigue can then propagate to the surrounding face, scalp, and neck muscles, a phenomenon known as pericranial muscle tension. This tension is a primary underlying cause of the common post-session tension headache.
The process of working through trauma often engages the sympathetic nervous system, the body’s fight-or-flight response. This physiological arousal leads to increased muscle contraction throughout the upper body, especially in the shoulders and neck. The physical expression of emotional stress through muscle bracing and clenching contributes to the development of a cervicogenic or tension-type headache. Crying or heavy breathing during emotional release can also lead to fluid loss and mild hyperventilation, potentially contributing to dehydration headaches.
Strategies for Managing Headaches During EMDR
Minimizing headache frequency requires proactive communication and targeted self-care measures. The primary action is to inform the EMDR therapist as soon as the head pain begins or is anticipated. A trained clinician can then adjust the pacing of the session, such as shortening the length of the sets of bilateral stimulation. If eye movements are the suspected cause, the therapist can switch to alternative methods of bilateral stimulation, such as auditory tones or tactile hand-held pulsars.
During the session, simple self-care techniques can mitigate the onset of discomfort. Taking frequent, short breaks allows the nervous system to settle and gives the eye muscles a rest from the repetitive motion. Maintaining adequate hydration is also important, as dehydration is a common headache trigger exacerbated by the emotional intensity of the session.
Post-session care focuses on physical recovery and continued self-regulation. Gentle stretching of the neck and shoulders helps release accumulated muscle tension from emotional bracing. Resting immediately after a session is highly beneficial, as the brain continues to process the material. For mild, persistent pain, over-the-counter medication can be used, although this should be discussed with a healthcare provider and therapist.
