What it’s for
- Morning light exposure
Specific amounts and schedules belong to the individual routine or product instructions.
Exposure to room lighting or a lamp after waking, with intensity and spectrum varying by device.
Purpose, evidence and practical considerations.
Specific amounts and schedules belong to the individual routine or product instructions.
Morning light can be a timing cue, but an unmeasured lamp setup has no defined clinical dose. Evidence for a specific therapeutic light box cannot be assigned to any full-spectrum LED.
Confidence: weak
Avoid glare and unsuitable ultraviolet lamps. People using light for a sleep or mood disorder need appropriate guidance, particularly with eye disease, light-sensitive medicines or bipolar disorder.
Light reaching the eyes can influence circadian signals. Timing, brightness, spectrum and distance affect the exposure; an unspecified LED cannot be treated as a standardized bright-light intervention.
