Search "ideal bedtime routine" and you'll get a checklist with about fourteen steps on it: dim the lights, no screens, herbal tea, journaling, stretching, a specific temperature, a specific playlist, a weighted blanket, a gua sha for your face for some reason. By the time you've done all fourteen steps it's basically morning. Sleep researchers actually care about a much shorter list than that, and knowing which few things do the real work makes the whole thing a lot less exhausting to keep up with.
The bed only means one thing to your brain (ideally)
The single most evidence-backed idea in this whole space isn't a routine at all, it's a concept called stimulus control, developed by psychologist Richard Bootzin back in 1972.1 The theory is simple: your brain learns associations through repetition, and if you consistently do things in bed other than sleeping (scrolling, watching TV, working, lying there stressed about not sleeping), your brain starts associating the bed with those things instead of with sleep.
Bootzin's original fix was blunt, and a little funny in its bluntness: only go to bed when you're actually sleepy. Don't do anything else in bed except sleep (and, generously, sex, the one exception the research allows). If you're lying awake for what feels like twenty minutes, get up, leave the room, do something low-key until you're sleepy again, then go back. Repeat as many times as needed, which, on a bad night, might mean you and your mattress have a slightly awkward on-again-off-again relationship until 2am. It sounds tedious, and it is, but it's one of the few sleep interventions with decades of solid evidence behind it, precisely because it targets the actual mechanism (a learned association) instead of trying to manufacture calm through vibes alone.
Passive listening is the one grey area worth calling out. The "nothing but sleep" rule is really aimed at things that keep you alert and goal-directed, scrolling, replying to messages, working, doom-scrolling the news. Putting on a calm narrated story or some white noise doesn't work against the bed-equals-sleep association the same way, it's part of the wind-down itself, not competing with it. It's the difference between using your phone to send emails in bed and using it to press play on something boring and then closing your eyes.
Consistency matters more than what you actually do
A 2024 study following over 60,000 people for nearly eight years found that sleep regularity (going to bed and waking up at roughly the same time every day) predicted mortality risk more strongly than sleep duration did.2 Not sleep quality. Not how many steps your routine has. Just consistency of timing.
This matters because it reframes the whole idea of a "bedtime routine." The routine's job isn't to be an elaborate ritual, it's to reliably happen at the same time every night, so your circadian system can lock onto a predictable schedule. A simple three-step routine you actually do every single night beats an elaborate ten-step routine you only manage twice a week.

Most individual sleep hygiene tips have surprisingly weak evidence on their own
A widely cited 2015 review in Sleep Medicine Reviews went through the actual evidence behind common sleep hygiene advice (avoiding caffeine, avoiding alcohol, exercise timing, noise, sleep timing) and found the evidence for several individual recommendations was thinner than commonly assumed, especially in isolation.3 That doesn't mean the advice is wrong, it means most of these tips work best as a bundle, addressing the general conditions that support good sleep, rather than any single one being a magic lever on its own.
Practically, this means you don't need to treat every item on a bedtime checklist as mandatory, or feel like a failure every time you skip the gua sha. If you love your evening coffee and it really doesn't affect your sleep (some people metabolize caffeine much faster than others, annoyingly), you don't need to feel guilty about ignoring that one line item. Optimize for the things that are actually disrupting your sleep, not for a perfect scorecard.
A routine that's actually realistic
Based on what the evidence does support, a version that doesn't require you to become a different person:
Pick a start time and protect it, roughly. Not to the minute, but within a 30 to 45 minute window most nights. This is the single highest-leverage thing you can do, per the regularity research above.
Dim the lights for the last 30 to 60 minutes. Bright light, especially blue-heavy light, suppresses melatonin release. You don't need special glasses, just turn off the overhead lights and use a lamp (more on why in blue light before bed).
Do something boring and non-stimulating. Reading a physical book, a wind-down podcast, a long narrated story (this is, not coincidentally, exactly what Smart Sleeping's episodes are built for) all work because they're calm and don't demand the kind of alert, goal-directed attention that keeps your brain wired.
Only get into bed when you're actually sleepy, not just because it's "bedtime." If you're not sleepy yet, do your wind-down activity somewhere else first.
If you're awake in bed for a while and it's clearly not happening, get up. Go do something dull in low light, then try again when you actually feel sleepy. Protecting the bed-equals-sleep association is worth the minor inconvenience. (One exception: if the reason you're awake is specifically anxious effort about sleep itself, tense, watching the clock, willing yourself to drop off, getting up isn't always the right move. We cover that specific case, and the counterintuitive fix for it, in sleep and anxiety.)
Consistency over choreography
A bedtime routine isn't a checklist you're graded on, it's a signal you're sending your nervous system, over and over, at roughly the same time, until it learns to trust the signal, the same way a dog learns that the sound of a leash means walk time. Simple and consistent will always beat elaborate and sporadic, and your nervous system does not care about the gua sha.
