Post-traumatic stress disorder is a serious mental health condition that can follow a frightening or traumatic event. It is treatable, and the treatments with the strongest evidence are trauma-focused psychological therapies, sometimes alongside medication, delivered by qualified professionals.
If you are in crisis or thinking about harming yourself, contact your local emergency services or a crisis line now.
What the research looks at
Research on light therapy and PTSD is at a very early stage. A few small pilot studies have tested transcranial near-infrared light, applied to the head, mostly in military veterans who had both brain injury and PTSD symptoms. Some participants reported improvements, but these studies were small, often without a control group, and cannot show whether the light caused any change.
There is no established evidence that red or near-infrared light therapy reduces PTSD symptoms.
What it is not
Light therapy is not a treatment for PTSD or any mental health condition, and our systems are not designed or tested for that purpose. It should never replace or delay professional support.
Where to get help
Your doctor can refer you to trauma-focused therapy. If symptoms such as flashbacks, nightmares, avoidance or feeling constantly on edge are affecting your life, reaching out is the right step.
