The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
in sleep, you also want to be a nose-breather because that's going to increase the amount of oxygen that you're bringing into your system and the amount of carbon dioxide that you're offloading, there are other positive effects of it as well, but you're basically reducing apnea, breath-holding in sleep leads to buildup of carbon dioxide and leads to increases in cortisol, which then decrease testosterone and decrease estrogen in negative ways across all sexes, okay?
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.
it has positive cosmetic effects, it reduces apnea, it offloads more carbon dioxide, it increases lung capacity, it dilates the sinuses, and it prevents apnea in sleep
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.
