Daily exposure to blue light each morning significantly improves Post-Traumatic Stress Disorder symptoms.  University of Arizona psychiatrists report these findings following their study of 82 PTSD sufferers.

 

All study participants committed to a daily 30 minute light treatment continued over a 6 week period.  The treatment group of 43 were exposed to blue wavelength LED lights operating at a wavelength of 469 nm while the 39 controls received amber LED light treatments at a wavelength of 578 nm.  All participants underwent neurocognitive and neuroimaging assessments to quantitate PTSD symptoms, sleep quality, and fear conditioning.

 

Blue light therapy reduced the numbers and severity of PTSD symptoms.  Light therapy improved sleep quality but both light wavelengths improved sleep.  The blue light improved the subjects abilities to extinguish fear memories.
