The analysis included multiple studies and found that light therapy was associated with significant improvements in PTSD symptom severity. Additionally, participants who received light therapy demonstrated better retention of extinction learning, a process crucial for reducing fear responses associated with traumatic memories. These findings suggest that light therapy could be a promising, noninvasive treatment option for alleviating PTSD symptoms.
