A recent study conducted by a team of researchers headed by instructor of psychiatry Mareen Weber, PhD, from McLean Hospital/Harvard Medical School in Belmont Massachusetts has indicated that bright light therapy may have benefits in improving a person’s sleep and may also be helpful in recovery following a traumatic brain injury (TBI) of a mild degree.
Within the study, the small group of 18 adult participants who had mild TBI experienced improvements in brain function, cognition, emotion, and sleep, after 6 weeks of use of blue wavelength bright light therapy in the morning for 30 minutes (or amber light in the placebo group).
Over half of the individuals in the treatment group experienced a reduction in daytime sleepiness. In the placebo group, 0 percent experienced this same effect. The bright light therapy was also connected with improvements in mood, speed of information processing, attention, memory, and executive functioning.
