Chronic Insomnia / Insomnia Disorder

Bright Light Therapy

Bright light therapy consists of properly timed exposure to bright light to help adjusting the circadian rhythm.1, 2

Bright light therapy timed in the morning after arising can advance or time circadian rhythms earlier and may be indicated for sleep onset insomnia and the more extreme version delayed sleep phase disorder. The delayed or later timed circadian rhythm may be present in evening types which experience difficulty falling asleep at a “normal time”, tend not to feel sleepy until quite late and have great difficulty waking up in the morning - commonly experienced by adolescents and young adults.3

Bright light therapy in the evening before sleep may be indicated for early morning awakening insomnia and the more extreme version advanced sleep phase disorder. The advanced or early timed circadian rhythm may be present in morning types which feel sleepy early in the evening with no difficulty initiating sleep but wake very early in the morning and not being able to resume sleep.4
