Use a bright 10,000-lux light soon after waking when natural sunlight is unavailable, especially in darker seasons or for early indoor schedules. Place it nearby while you make coffee, journal, or get ready for the day for about 5–10 minutes rather than staring directly at it. The goal is to mimic morning daylight cues that help anchor circadian rhythm and improve alertness and mood.
