Portable Travel Light Therapy
Portable travel light therapy delivers morning lux at destination when outdoor sun is unavailable—short post-wake sessions, never bright light at local night.
Portable travel light therapy uses a compact 10,000-lux lamp or verified wearable light source at destination morning when weather, hotel orientation, or winter blocks outdoor sun. Sessions of fifteen to thirty minutes soon after waking advance or anchor phase depending on trip plan.
Do not blast bright light at destination night—that delays sleep.
Common questions
-
Can a phone screen replace a travel lamp?
Phones are too dim and the wrong use pattern for phase shifting. Use outdoor light when possible; a dedicated lamp or brief outdoor walk beats scrolling at max brightness.
