Primary

Shortens time needed to fall asleep

Valerenic acid and related constituents of valerian root can strengthen GABA-related inhibitory transmission, so the wait from lying down to actually sleeping is often shorter. People whose mind will not stop and who toss in bed more often see change in speed of falling asleep after several continuous weeks.

Primary

Raises subjective sleep quality

The same sedative-leaning path also lands on nighttime awakenings and waking refreshed; trials often record subjective sleep scales. People who have slept yet still feel unfilled and who wake easily at night more often see a difference in sleep continuity and next-day alertness after several continuous weeks.
