Recent Reports have merged claiming that post-traumatic stress disorder (PTSD) symptoms can be reduced after blue light therapy exposure. Patients usually experience lack of sleep quality with PTSD, according to research by the University Of Arizona College Of Medicine.

Post-traumatic stress disorder (PTSD) symptoms include poor sleep quality which can also affect physical and mental health. It may also lead to chronic health conditions and leave a negative impact on cognitive abilities, such as healing and learning. 

Researchers have come up with a study that shows how beneficial exposure to morning blue light is and how it impacts overall health. The other factors also conclude that blue light exposure also increases the effectiveness of the treatment in patients with PTSD.


Psychiatry professor William “Scott” Killgore, Ph.D., director of the Social, Cognitive, and Affective Neuroscience (SCAN) Lab and senior author said, “This research is exciting and unique because it points to an easy-to-use method for helping those with PTSD to retain the benefits of therapy long after the treatment ends”. He further said that “Morning blue light treatment improves sleep complaints, symptom severity, and retention of fear extinction memory in post-traumatic stress disorder.”

Dr.Killgore and the SCAN Lab team performed this research about daily exposure to morning blue-wavelength with clinically significant levels of PTSD.

The reason behind this research was to learn how blue light therapy can help by improving sleep quality and increasing the effectiveness of PTSD treatment.

Dr. Killgore also said that “while the limitations of the research include its modest sample size and difficulties monitoring compliance, the possibilities of utilizing a treatment that is relatively simple, drug-free and inexpensive can offer hope for the large population of people living with the intense challenges of post-traumatic stress disorder”.

This nonpharmacological intervention is a promising life-changing and life-saving possibility for people suffering from PTSD”, said Jordan Karp, MD, Professor, and chair of the College of Medicine.
