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.
so that demonstrated to us that there's something special about sleep that is concretizing almost literally like taking things and setting it in concrete and then the question became again mechanistically how how is it and it's important to understand mechanism because it has ramifications for diseases and Medicine how is sleep doing this fantastic saving of memories
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.
this idea of brain plasticity and there is a model where if you kind of patch the eye of an animal and then you measure the visual cortex what you see is that once you patch one eye the brain says well we're not going to waste the real state of that one eye that's no longer doing visual processing we're going to shift a lot of that over to the other eyes territory and give it even more kind of rich connective fidelity as it were so you've got this model of what's called monocular deprivation plasticity which is a classic model of how the brain rewires itself for things like learning in memory
Sleep enhances memory formation by growing new dendritic spines in brain.
Sleep enhances memory formation by growing new dendritic spines and synapses in brain.
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.
