Chronotype Aligned Light Exposure
Chronotype aligned light exposure times bright and dim light to shift phase—morning for owls, cautious evening light for advanced larks—with consistent anchors.
Chronotype aligned light exposure times bright outdoor or lamp light when your phase needs advance or delay—morning light for delayed owls, carefully timed evening light for extreme larks who fall asleep too early. Random midnight screen brightness works against you.
Consistency for several days beats one heroic session. Pair with anchor wake times and dim evenings.
Common questions
-
How long does aligned light take to work?
Expect several days of consistent morning bright light for delayed types. One sunny walk helps mood but phase shifts need repetition plus stable wake times.
