The 10pm habit that changes how you feel at 7 am
What you do in the hour before midnight shapes everything about how you wake up. Here's the science - and the simplest way to use it.
Most people treat sleep as something that just happens when they lie down. And most people wake up tired.
That's not a coincidence. Sleep quality is largely determined not by what happens when you're unconscious — but by the 60 minutes before you get there. Your body doesn't switch off like a light. It transitions. And that transition can either be supported or sabotaged, usually without you realising which one you're doing.
The good news: the shift doesn't require a complete lifestyle overhaul. It requires one consistent habit, done at roughly the same time, every night.
A landmark study published in Sleep Medicine Reviews found that pre-sleep arousal, mental and physical activation in the hour before bed — is one of the strongest predictors of poor sleep quality, independent of total time in bed. In other words, how wound-up you are at 10pm predicts how rested you'll feel at 7am. More than almost any other factor.
This isn't about willpower. It's about biology... specifically, the circadian rhythm: the internal 24-hour clock that governs when your body wants to sleep, when it wants to wake, and how deeply it rests in between. Your evening habits either align with that clock or fight it.
What your body is actually doing at 10pm
Around 9–10pm, for most adults, something important begins. Melatonin production rises sharply - a signal from the brain that darkness has arrived and sleep should follow. Core body temperature begins to drop. Cortisol, the stress hormone that keeps you alert, starts its nightly decline.
Your body is ready to hand over. The question is whether you let it.
Bright screens, stressful conversations, late meals, alcohol — each one sends a conflicting signal. The brain gets confused about what time it is. Blue light from devices suppresses melatonin production by up to 50%, effectively telling your brain it's still mid-afternoon. Your body tries to sleep. Your brain says: not yet.
That conflict is why you lie in bed for 45 minutes. Why you wake at 3am. Why you hit snooze twice and still feel half-asleep by 9am.
Research from Harvard Medical School found that people exposed to room-level light before bed took on average 71 minutes longer to fall asleep and experienced significantly less REM sleep — the stage responsible for emotional regulation, memory consolidation, and how refreshed you feel upon waking. (Gooley et al., 2011)
What the hour before midnight actually looks like
Dim everything down
Overhead lighting keeps cortisol elevated. Switching to lamps or warmer, lower light tells your brain the day is ending. Research from the Sleep Foundation consistently shows that light environment is one of the most underestimated sleep factors — and one of the easiest to change.
Change what you're looking at
You don't have to put your phone away entirely (though it helps). Switch to night mode. Put on something low-stakes — a slow documentary, a podcast, a book. The content matters as much as the screen time: emotionally arousing content before bed significantly delays sleep onset and reduces slow-wave sleep — the deepest, most physically restorative stage.
Take your Was It All A Dream?
This is the moment the ritual anchors. A few drops of Inora's Was It All A Dream? ... the sublingual format means absorption is fast, reaching the bloodstream before you've finished your tea. Three slow breaths. And the physical act of the dropper itself becomes a cue: the brain learns to associate it with rest. Behavioural sleep research calls this stimulus control — and it's one of the most evidence-based tools in sleep medicine.
Do something quiet
Read. Stretch lightly. Write three things down from the day. A 2018 study published in the Journal of Experimental Psychology found that writing a to-do list for the following day — just 5 minutes — helped participants fall asleep significantly faster than journalling about what they'd already done. Offload the mind. Let the body follow.
Cool, dark, consistent
Core body temperature needs to drop 1–2°C to initiate sleep. A bedroom between 16–19°C is optimal for most adults. Dark enough that you can't see your hand in front of your face. Consistent enough that your body knows what's coming — and starts preparing before you even lie down.
The Inora Study
What happens when you make this a habit
After a medically-supervised 28 day study with adults aged 21–65 using Inora as part of a consistent nightly ritual, the results weren't subtle.
reported more restorative sleep
woke feeling more refreshed
felt more alert during the day
Why 28 days?
Research on habit formation consistently shows that behavioural loops — cue, routine, reward — require repetition over weeks, not days, to become automatic. 28 days is the threshold at which a sleep ritual stops being something you do and becomes something your body expects. That's when the real results compound.
The Takeaway?
You don't need a perfect routine. You need a consistent one.
The research is clear: it's not what you do, it's that you do it at the same time, in the same order, every night. Your body learns the sequence. Your brain starts winding down before you've even made it to the bedroom.
That's the 10pm habit. Not a rigid checklist — a direction. Dimmer light. Quieter content. One small, intentional act that tells your body: we're done. Rest now.
