Human trafficking causes deep trauma & PTSD. Discover how red/infrared light therapy (photobiomodulation) offers new hope for brain healing & mental health recovery.
Human trafficking involves force, fraud, or coercion to obtain labor or a commercial sex act. Each year, millions of men, women, and children are trafficked worldwide—including within the United States. It can occur in any community, and victims may be of any age, race, gender, or nationality. Traffickers often use violence, manipulation, or false promises of well-paying jobs or romantic relationships to lure victims.
Recent trauma studies have broadened understanding of trauma and its impact. They describe a wide range of post-trauma symptoms and show that multiple interacting factors influence severity. For example, more intense symptoms are linked to repeated victimization that often begins in childhood and disrupts parent-child relationships. Greater impact is also associated with co-occurring behavioral health problems such as substance-use disorders, limited social support, lower socioeconomic status, and stigma surrounding specific traumatic events. Trauma exposure lies on a continuum of “complexity,” from a single incident in adulthood (e.g., a car crash) where life is otherwise stable, to repeated, intrusive trauma that is “frequently interpersonal and often accompanied by significant shame or stigma.” Victims of human trafficking, especially sex trafficking, typically fall at the complex end of this continuum.
Most research on trauma and trafficking focuses on foreign-born women and girls exploited commercially. In addition to brutal physical and sexual violence, victims often endure multiple layers of trauma: psychological harm from captivity, fear of retaliation if they attempt escape, brainwashing, and, for some, a long history of family or community violence. Emotional consequences can be persistent and severe; survivors may experience anxiety, panic disorder, major depression, substance-use disorders, eating disorders, or a combination. Trauma inflicted by someone once trusted can lead to pervasive mistrust of others, complicating recovery and helpers’ efforts. Some survivors develop Post-Traumatic Stress Disorder (PTSD), a diagnosis originally created for combat veterans and disaster victims but now applied to other traumas, including trafficking. Core PTSD symptoms include intrusive re-experiencing (flashbacks, nightmares, intrusive thoughts), avoidance of trauma reminders, and hyper-arousal (exaggerated startle, poor concentration). If untreated, PTSD tends to become chronic and debilitating in both adults and adolescents. These post-trauma responses can impair functioning, leading to emotional dyscontrol, sudden anger or self-injury, concentration problems, suicidal behavior, dissociation, and increased risk-taking.

Affordability, service responsiveness, and sheer availability are repeatedly cited by providers as major hurdles for both international and domestic trafficking survivors. Shame is viewed as the single greatest barrier to seeking care; stigma surrounding mental illness is especially pronounced among foreign-born and male victims. Some survivors willingly seek help for physical complaints, yet the underlying trauma driving those symptoms often remains unaddressed. For U.S. minors, confidentiality fears, lack of ID or insurance, and complex jurisdictional rules create additional obstacles. Child-welfare systems are assumed to cover mental-health needs, yet reporting a minor to protective services does not guarantee treatment. If the abuse was not inflicted by a parent or legal guardian, the case may fall outside the system’s remit, leaving the youth unserved. Even with insurance or child-welfare involvement, referral options are scarce; one community reported a seven-month wait for adolescent psychiatric care. Once services begin, insurance or funding caps frequently curtail the long-term treatment many survivors require. Traditional weekly-appointment models fit poorly with transient or crisis-driven lives, especially for minors. Flexible, trauma-responsive care exists in theory, but current systems rarely support it; immediate crisis intervention is usually obtainable, yet sustained trauma recovery remains an unresolved challenge.
Over the past two decades, studies have explored infrared light (600–1000 nm) for potential neurobiological benefits. Laboratory work suggests the light may activate mitochondria, up-regulate transcription factors, and increase growth-factor production, possibly fostering new synapses and neuronal differentiation.
In animal models, infrared photobiomodulation (PBM) has been associated with smaller brain-injury volumes after stroke, reduced depression-like behavior, and diminished markers of PTSD, Parkinson’s disease, and Alzheimer’s disease. Michael Hamblin, Ph.D., of the Wellman Center for Photomedicine, defines PBM as “the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying.” Human efficacy and optimal dosing remain under investigation.

The scalp and skull are substantial barriers. Studies suggest that 0.9–15 J/cm² at the target tissue may be needed to engage mitochondria and related cellular events. A 0.5 W LED directed at the cranium could deliver only ≈0.0064 J/cm² to the cortical surface—roughly 1/140 of that lower threshold—so little or no energy is expected to reach deeper structures implicated in stroke, Parkinson’s disease, Alzheimer’s disease, or many brain injuries.
Patented LED-mask systems apply transcranial near-infrared laser therapy (NILT). In company-sponsored open-label studies, participants have reported fewer headaches, improved cognition, better sleep, less irritability, and reduced depression. An open-label trial (n = 39) noted a 92 % response and 82 % remission rate for depressive symptoms, with some participants noticing changes within four sessions and sustained benefit for many by eight. These findings are encouraging but remain preliminary.
We continue to explore why some LED devices produce measurable benefits even when little light appears to reach the brain. One possibility is a systemic or “remote” photobiomodulation effect initiated in irradiated skin rather than direct cerebral illumination.
