A protocol pairs a goal with a wavelength, dose and timing — the practical translation of light into a daily routine. Each entry below names the situation, who it suits, the target wavelengths, how long to dose and when, plus an honest note on what the light can and cannot do.
Filter by device and category, or describe what you're after — jet lag, sore knees, dull skin, low energy. Every routine names its wavelengths, dose and timing so you can match the light to the goal.
Low morning energy, slow to get going
For: Office worker
Faster morning activation and alertness
Bright morning light supports alertness/circadian timing; 100 Hz daytime pulse is a hypothesis, not head-to-head proven. Wellness support, not a treatment.

For: Student
Cut through morning grogginess
Morning light can reduce sleep inertia; specific pulse setting unproven. Not a cure for any sleep disorder.
Afternoon slump (post-lunch dip)

Recover daytime energy after social weekend
Morning light helps re-anchor rhythm after late nights; it does not erase the sleep loss. Wellness support.
Jet-lag daytime sleepiness at destination

Jet lag flying east, multi-zone
For: pilot/cabin crew
Speed eastward re-entrainment
Crew schedules complicate timing. General phase-advance principle; not crew-medicine advice.
