Shortens time needed to fall asleep
Exogenous melatonin mimics the pineal rise in darkness; most trials watch sleep-onset time shorten. People on shift work, with overly bright night light, or with delayed sleep onset most often match this signal through falling asleep faster and waking less at night.
Support jet-lag phase adjustment
Across time zones or shift work, exogenous melatonin pulls clock phase toward night in the target zone. People on long-haul flights and night work most often judge whether phase has aligned from sleep-onset timing, daytime alertness, and whether local routines can be kept.
