Practice safety
Sleep duration target is generally low risk, but persistent insomnia, loud snoring, breathing pauses, dangerous sleepiness or major mood changes need clinical assessment rather than increasingly rigid self-experimentation.
Sleep duration target changes sleep opportunity or environmental cues that help align the sleep-wake cycle. Effects depend on consistency and whether another sleep, medical or environmental problem is present.
Purpose, evidence and practical considerations.
