The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
avoiding caffeine and alcohol, certainly within the six hours prior to bedtime, but I would say in the 8 to 12 hours prior to bedtime would be even better or not drinking alcohol at all, or I know there are people out there that don't drink caffeine at all, I'm not one of those people, but restricting that caffeine intake to the very early part of the day, that has been shown to improve the quality and the overall architecture of sleep and slow-wave sleep in particular.

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
exercise of this sort turns out to be a very potent form of improving slow-wave sleep.
are you ingesting caffeine after 2 pm if the answer is yes you want to limit or eliminate caffeine after 2 pm maybe even push it back to noon or earlier
did you drink caffeine in the afternoon or alcohol in the evening in which case the quality will be diminished
Avoid stimulants before bed: limit caffeine and alcohol intake before bedtime, as they can interfere with sleep quality and duration.
Try to avoid caffeine and other stimulants at least 12 hours before bed. Experiment with not consuming caffeine to evaluate if caffeine is negatively effecting your sleep. Avoid alcohol all together.
10 minutes of bright outdoor light within the first hour of waking anchors the circadian phase and improves sleep onset that night.
Morning sunlight exposure shifts the cortisol awakening response forward, improving daytime alertness.
Long-term morning sunlight reduces age-related macular degeneration risk.
Sleep regularity predicts all-cause mortality more strongly than sleep duration.
Tracking deep sleep on a wearable accurately reflects EEG-measured slow-wave sleep.
Caffeine has a half-life long enough that consumption after 2pm measurably degrades deep sleep in slow metabolizers.
