Up at 3:30 am; meditate, but no coffee (keep adenosine high); work out HARD (it’s already 1 pm in my destination…again, more adenosine)

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.
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.
Even 12 hour jumps for short 3 days trips are very easy to manage.
blue light blocking glasses on the plane from PST to EST (get melatonin ready)
the moment I wake up, assume I’m in destination time zone and manage my adenosine, cortisol, and melatonin accordingly
immediately hit blue light; take 200 mg modafinil
I can go to eight hour time zone away, be 100% functional the minute I get off the plane. That's awesome. Get right into routine and rhythm.
So I don't fly that much anymore and when I do um I I'm mo most of my stack is around sleep, right? So that's so so kind of like what I'm thinking about when I'm flying is how do I eliminate jet lag?
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.
