Regularity beats duration
The single most under-rated item on this list is schedule variability. Large cohort studies find that irregular sleep timing predicts metabolic and cardiovascular outcomes independently of how many hours you sleep. Fixing wake time first — including weekends — moves more components than adding an hour in bed.
- • Fixed wake time anchors the circadian clock
- • Time in bed is not time asleep — efficiency is the ratio
- • Sleep latency over 30 minutes is the classic insomnia marker
When to escalate
Snoring plus daytime sleepiness plus unrefreshing sleep is the classic apnea triad and warrants a proper evaluation rather than sleep hygiene tips. Chronic difficulty falling or staying asleep for three nights a week over three months meets the duration criterion for chronic insomnia, which responds best to CBT-I.
FAQ
What is a good sleep quality score?
On this 0–28 index, 0–6 is good and anything above 13 counts as poor. Lower is better because every item describes a problem.
Does more sleep always improve the score?
No. Duration is only one of seven components. Fragmented nine-hour nights score worse than consolidated seven-hour nights.
What actually fixes poor sleep?
For chronic insomnia, cognitive behavioral therapy for insomnia (CBT-I) has the strongest evidence base and outperforms sleep medication over the long run.
