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.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
After we discovered my IJV, we used our EPIQ ultrasound machine and measured my JV blood flow in all sleeping positions & w/ different pillow configurations.
we found that when I laid on my right side I had the best flow on my left side I had the second best flow
so the one that proved to have the greatest flow is this really skinny pillow at the base it was the thinnest pillow I could find and then this guy which has an indentation for my neck so I was able to learn proper posture in sleep to ensure flow from my brain and then we validated all these markers we've done follow-up MRIs and follow-up examinations with ultrasound on the flow and these all show improve markers
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.
