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.
but I can tell you the first two the stimulus control and and the time and bed restriction those among the earliest earliest parts of cbti and what we know from dismantling studies is when you take either of those out of the treatment no dice
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.
the principles of what I'm doing are not at all bespoke I'm doing the the you know time and bed restriction stimulus control the cognitive Tech techniques the relaxation techniques and and the Sleep hygiene those are the five major components
we restrict the amount of time that a patient is in bed to match how much time their body can actually produce of sleeping a lot of times people with insomnia will say okay I need to be in bed for at least 12 hours if I want to get seven hours of sleep right
And as far as I know in CBTI, almost nobody's restricting less than 5 and 1/2 hours. 5 and a half seems to be the floor.
all of the behavioral changes to mitigate insomnia um which fall under the themes that are I I think kind of bucketed as sleep hygiene, stimulus control, time in bed restriction, cognitive techniques, and relaxation techniques.
the sleep restriction part, matching the amount of time that you're in bed to the amount of time that you can actually 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.
