Bedtime procrastination isn't laziness — it's the self-time your day took away
For most people bedtime procrastination runs only about half an hour; the real problem is a daytime with no autonomy. Blue-light glasses do less than advertised, while indoor lighting matters more. And self-compassion improves sleep more than forcing yourself into bed early.

Mainstream sleep advice is something ordinary people simply cannot follow
After Hill moved from Australia to the United States and went from a steady job to working as a creative, her sleep got worse and she developed short-term insomnia. She found that mainstream sleep advice — no screens before bed, for instance — was very hard for ordinary people to act on, so she went on to do a PhD in behavioral psychology, studying sleep and behavior change. A video she made about sleep deprivation drew 500,000 views, which showed her that sleep science needs a more human way of talking about itself.
— Alie WardADHD may in fact be a disorder of circadian rhythm
A paper from December 2025 recasts ADHD as a circadian rhythm disorder: close to 80% of patients have a delayed sleep-wake cycle. The treatment suggestions include a fixed wake time, morning light exposure, screen limits, and low-dose melatonin. The key mechanism is that ADHD affects time perception, so people underestimate at night how long a task will take, and push their bedtime back.
— Alie WardRefusing to go to bed is how you claw back the self the day took
Hill's qualitative research found that the core motive behind bedtime procrastination is a fight for "self time": the day is filled up with work and obligations, and only at night does a sense of control return. It shows up most sharply in people starting new jobs, new parents, and caregivers. Night is also a window for exploring identity — LGBTQ+ people, for example, may only be free to express themselves late at night — which makes the procrastination not just avoidance but resistance.
— Alie WardMost people delay only half an hour, and the internet's story scared them
The data show that most participants put off bed by 0-30 minutes a night, a smaller group by 60 minutes, and extreme cases by 125 or 175 minutes, or even 2-3 hours. That changed how the researcher defines the problem: many of the people who signed up were not actually delaying for long, but had been frightened by a perfectionist narrative circulating online. The host jokes that she belongs to the extreme group.
— Vanessa HillBlue-light glasses are no magic bullet, and misused they make things worse
Research from 2025 indicates that blue-light glasses are not a magic bullet: the effect depends on the filtering characteristics and on when you wear them, and using them wrong can backfire. The recommendation is to pick a product with an MFD value greater than 1, or to consult Consumer Reports' testing, where the cheap brand Uvex Skyper actually performed best. But the researcher cautions that the crux of sleep-onset procrastination may not be light at all — it may be long-standing habit.
— Vanessa HillThe main suppressor of melatonin is your room light, not your screen
Compared with the blue light from devices, indoor lighting suppresses melatonin far more severely. Testing at Monash University found that roughly half of homes have light bright enough to suppress 50% of melatonin. The fix is to switch to warm-colored bulbs, or use smart lights that mimic the flicker of a candle, so the environment naturally "cools down" before bed.
— Vanessa HillProcrastination is treated with a substitute behavior, not an earlier bedtime
The lever for changing bedtime procrastination is the habit system: first identify the trigger (time, emotion, place) and the reward you are getting, then hand the slot over to an explicit substitute behavior. For instance, watch one 30-minute episode of a show instead of scrolling endlessly, and set a sleep timer at the same time. The library of behavior change techniques contains 93 methods; the researcher considers monitoring and substitution the most practical.
— Vanessa HillTopping up self-time during the day does not dissolve late-night delay
A 2025 clinical trial tried to dissolve late-night procrastination by topping up "self time" during the day — subjects were encouraged to listen to podcasts or read during their lunch break, their commute, or after dinner. It did not work. The researcher therefore infers that what people need may be precisely the darkness and quiet of night, which a daytime substitute cannot supply. Negative results carry information too, and the scientific community should encourage publishing them.

It did not work which is interesting in itself, right like this is why in science we encourage people to publish negative results because they still tell you something

How to listen
People who put off bedtime and are hard on themselves about it, founders interested in the mechanics of behavior change, and engineers who need to manage their energy better.
