    The title of the article is irresponsibly chosen.

    - My time in the field of psychology has made me think that the use of imprecise language for describing psychology has a large and problematic societal impact

    ADHD is correlated with but is NOT a "circadian rhythm disorder". This is definitionally true.

    There are many causes of ADHD. One of them is likely sleep issues.

    Ok after reading a chunk of this the correlation is pretty wild. Having the data it’s quite striking. Sleep intervention as a form of ADHD treatment has always seemed reasonable to me but this gives a lot more clarity to the approach and mechanisms.

    For me, the seasonal aspect of it aligns with their blue light findings (both driving symptoms and aligning with improvement under the intervention of having a grow-LED garden setup on my desk), and in a second maybe related matter we’ve found using blue light blocking glasses an hour before bed to be the most impactful single intervention around sleep quality and onset (the ones that are like orange laser safety glasses, not the mildly reflective desk-work glasses)

      I had great success reflecting 80,000 lumens of work lights off my living rooms ceiling during winter for a couple years.

      At a new home, I remodeled four rooms to have three bands wide of LED lighting surrounding the ceilings, hidden from below by cove molding. It is an actual sunny day, with an “an actual” sunny sky inside. Winter, midnight, eclipse? Not a concern.

      Having all that intense light reflecting off entire ceilings creates soft diffuse lighting, no shadows, even though it is extremely bright.

      Helped a lot with waking up and avoiding depression, all year round.

      On the sleep treatment, anything that can help sleep is good, my body has always operated well on a 30 hour day, which means terribly almost all the time, by default. But I do a lot of things that help, so my sleep is pretty good most of the time.

      I would see sleep aids as a pretty narrow interventions relative to my ADHD.

      Correlation would be nowhere near equivalence.

        Ah on the 30 hour day: I had some success living a 28 hour day for a few months, which has the nice property of meaning your awake hours are identical week to week making it at least somewhat possible to interface with polite circadian society.

        6x 28 hour days pack cleanly into a 7-day week, so all Mondays you wake at the same time, then all Tuesdays you wake 4 hours later and so on. It was one of the most productive times of my life but ultimately left my partner feeling unhappy and lonely.

        Fuck it we do our best with 24 hour days…

      • brailsafe 53 minutes ago
        The 30 hour day feeling resonates. If I have no external schedule or I'm just living as I see fit, I end up gravitating to 3am bed, ~12pm wake sorta schedule. The only real problem is that it's functionally incompatible with jobs and many other services, even fully remote
        • hax0ron3 28 minutes ago
          Same. For me it's more like 4-6 am bed.

          I also work best in long bursts of up to 12 hours, with days of full rest in between bursts. I don't do well with a five days a week 9-5 work schedule.

          And timeline urgency / time pressure tends to do well at putting me into deep flow state, whereas it can be hard for me to get into flow state for work otherwise.

        I can confirm this effect. One winter I left 2x300w living room lights on perm, and it had a dramatic effect. The only issue is that its nice to turn lights off at night, and if you do that, now you're in habit-dependent territory.

          one thing i've been paying the adhd tax on is automating / making habits lower activation energy. smart bulbs / blinds are a great thing for me especially when i am already in bed and have too much executive dysfunction to walk 3 feet to the light switch / shade

          I had a contractor and an electrician! There is some significant power draw.

          It’s been five years, so I expect the best components are different, more efficient and cheaper.

          In winter, the lights can be considered part of my heating system. In summer, windows get opened. If I did it again, I would have some little fans up there expelling air from the cove directly outside.

          But that is fine tuning. I am really happy. (When the lights are on. /h)

        Indeed.

        The following (informally described) symptoms are well-known consequences of ADHD:

        - Delayed Sleep Phase [1]

        - Staying Up Late [2]

        - Revenge Bedtime Procrastination [3]

        Newsflash, getting a full night's sleep helps alleviate ADHD symptoms, while being perpetually sleep-deprived wrecks us.

        But there are reasons why we stay up late. Simply forcing us to sleep doesn't address those reasons.

        Which is why I wrote about it so much, and keep spamming these links even though it feels so darn obvious. Not to the authors of the study, it appears.

            You may eventually find yourself in a situation where the tradeoff is worth it.

            E.g., you have a family to feed, and your ability hold a well-paying job hinges on your performance.

              > E.g., you have a family to feed, and your ability hold a well-paying job hinges on your performance.

              I can do all of these things anyway. Of course, this does present the potential reality that were I able to sleep like people, I could be even more successful, but after a near death experience, then disability, I've learned to be happy with where I am.

              We know full well the trade-off is worth it. It's just that we can't have it.

            It's hard to interface with society this way. I'm the same as you and have waxed and waned many times. There are periods where I'm all about being social and living a normal life. There are other times where I'm just down to only sleep when I'm dead tired (as opposed to using drugs to keep me in normal rhythm). There are tradeoffs
            • alterom 13 minutes ago
              Consistent inconsistency is the part of the ADHD package.

              It's not that there aren't tradeoffs, it's that we don't get to choose these tradeoffs (as in: the cost of choosing is huge and nonzero).

            >Lots of the things on this site are normal things that everyone experiences to some degree ...right?

            Everyone may experience some of those things some of the time, particularly if they are overwhelmed, overworked, overstressed, etc.

            ADHD is experiencing most of these most of the time - as in all the time - for your entire life.

            As an analogy: everyone may experience toe pain sometimes if and when they stub their toe on kitchen table leg.

            But if it hurts like that all the time, for your entire life - you'd get it checked out, right? There are solid chances something is different about your body.

            Now multiply that by 100.

            To reword this: say, each relatable entry on that page is a 2% likelihood of ADHD.

            If you relate to 100 of them, the chances you're not ADHD drop to 13%.

            I've got enough people through an official diagnosis this way that this page, in itself, is a decent enough diagnostic tool.

        Then add in the use of powerful stimulants (e.g. Adderall) to power through a workday, only to have that cause insomnia that night, and a wrecked sleep schedule for the following 3 days.
  • anigbrowl 22 minutes ago
    Has anyone considered that one reason for being/staying awake late at night that's very salient for ADHD people is that night tends to be much quieter, so it's a period when it's much easier to think/read/work without constant interruptions. Noise pollution isn't taken seriously enough.

    ADHD meds also impact circadian rhythm. So I don't really know how a study could look at this dynamic with any usefulness.
  • SamDc73 18 minutes ago
    Three things that helped me with my circadian phase (to certin extend)

    1) Melatonine 300mcg 5-6 hours befor desired sleep time 2) 10k lux light for 30m when waking up 3) Nobeltin (nootropic) it enhances clock amplitude, so I do get less sleepy during teh day and more sleepy at night ..

    things taht kind of helped but find hard to keep: Keto (I feel less sleepy on Keto, and easier to fall a sleep but it's been a while since ive been on keto)

    adhd is a socially constructed disorder with significant heterogeneity and is only becoming moreso with the advent of scrollable video media and patient communities/advocacy. i am highly skeptical of results pointing to an easily identified physiological cause. the studies cited in this paper are generally low quality and fall apart under scrutiny.

      As a person whose extreme lack of attention went away spontaneously once after a meditation retreat I am skeptical of most things anybody says about ADHD.

    Dr. Sandra Kooij is a good person to look up if you are interested in adult ADHD and sleep. She has a book about it. From what I remember, there are a few things that are known:

    1. a large majority of ADHD sufferers are phase-delayed and struggle with insomnia

    2. you can induce ADHD-like symptoms in normal people by restricting sleep

    3. Some of the interventions that improve sleep timing and quality affect ADHD (but it isn't a total cure)

    • al_borland 54 minutes ago
      > 1. a large majority of ADHD sufferers are phase-delayed and struggle with insomnia

      I would think this wouldn't be such a problem if society would acknowledge night owls exist and allow work to adjust accordingly. Forcing a night owl to live the life of a morning lark is likely not the best way to get their best work. The person suffers who has to try and live in a world not designed for when they sleep, and the employer suffers by getting less out of those people.

      I have ADHD and left to my own devices I would go to sleep somewhere between 2-4am. At work, I don't function so well before about 2pm some days... and by that point that day is almost over.

      • brailsafe 47 minutes ago
        Completely agree, and tend towards the same schedule. I don't even mind working in-person with people, but this idea that everyone should just be uniformly aligned to operate on the same hours is alienating and humiliating at times.

        > I have ADHD and left to my own devices I would go to sleep somewhere between 2-4am. At work, I don't function so well before about 2pm some days... and by that point that day is almost over.

        Indeed. I've struggled with it since childhood, not only me. The same "symptoms" for lack of a better word are seen with my mother, my aunt and my grandmother. All are night owls, all sleep poorly etc.

        For whatever reason, regardless of how much sleep i've had, my brain begins to kick into high gear with a clarity of thought and capacity to dedicate myself to things starting at about 9PM. This remains true REGARDLESS of sleep, how well rested I am, general health, etc. I could have had NO sleep for 24 hours, still be away at 9PM the next night, and it's like a switch.

        The ONLY time this ever differs, for reasons still unknown, and where I fit into "normal society" is for whatever reason, when I visit Russia (which I have not done for some time for obvious reasons.)

        When I am in Russia, with no effort at all, I sleep normal hours without issue, and wake up during the day time actually well rested. This ceases once I return to my timezone. This same pattern is not seen when say, I visit the US instead.

        If only I could harness this magic...

      • luckydata 39 minutes ago
        being a night owl is not good for your health for a lot of reasons (I am one).
        • theshackleford 18 minutes ago
          This would depend on the individual, or so my sleep team, including my sleep doctor suggest.

          It is better for me to align with a pattern where I get some level of restful sleep, as opposed to one where I do not ultimately.

          In an ideal world, you are obviously correct, but in the world between a severely disturbed sleep where I get a handful of hours of actually restorative sleep, vs once where I actually sleep for 7 hours? One wins over the other.

          And yes, given I have an entire medical team (for other reasons, I have a SCI) I have done about everything you can to resolve sleep. Between ADHD however, symptoms related to the SCI etc, we really do just have to go with whatever we can reasonably get.

    I believe it. I even sought out medical advice on how to best deal with it all. I was given the usual recommendation of low-dose melatonin and light therapy.

    However, my issue at the time was that I could never find a light with high enough lux values that I felt like I could trust. Plus, another issue with light therapy is that one can basically never stop for any moderate amount of time, and well, my ADHD makes that near impossible.

    I honestly think I would have better success with sleep issues if I could just control my own schedule or have a flexible schedule, but that is not really a luxury most jobs can provide.

  • sid_talks 57 minutes ago
    For a time I had to wake up at 6AM for work and it was a period where I struggled the most with my ADHD symptoms.

    I hope there is more awareness in the future about the importance of sleep for neurodivergent people. This could help with the social jet lag most of us feel with having to follow a schedule that simply does not work for us.

      I was formally diagnosed as a kid but didn’t do the drug route due to my father not liking these new drugs. I’m in my 40’s now and only started enforcing a sleep routine 10ish years ago. Eg. Bedtime at 11 and get up when alarm goes off at 7:30. And the effect on me was astounding. Everything just levelled out. I still like/need a coffee in the morning.

    • tombert 1 hour ago
      I still have problems, but my life categorically improved once I got diagnosed and treated for obstructive sleep apnea. I focus on things much better, I'm better at juggling tasks, and I'm just nicer to people, or at least my fuse is considerably longer than it used to be. Also I'm sure my wife is grateful that I'm not snoring or gasping for breath every night.

      I would highly encourage anyone who can get a sleep study done to do it. Most insurance companies will at least cover the sleep study and sleep sleep apnea can lead to a lot of considerably-more-expensive issues later down the line. It's not very invasive anymore, all they had to do was have me sleep with a pulse oximeter for a few nights and apparently that was enough.

        I was like you. A year ago, I was tired as hell despite sleeping (well, not enough, but I've never slept 'enough'). A few people said sleep apnea but i was not overweight and didn't snore. I tried the test anyway, and it turns out I wasn't breathing. I used an oral appliance and a year later, it's gone and I feel better.

        Also, without doing anything my triglycerides, LDL cholesterol and blood sugar which had gone way out of whack, went back to normal.

        I started using my oral appliance on a Monday. That Friday I was so energetic I ran 12 miles in one go. I hardly ever run or even practice that much, but I was just so wired that I couldn't help it. It was an amazing feeling. I highly suggest sleep apnea treatment even if you don't think it sounds like you.

    I've been using a smart switch to fade in a light (one of the "sun-like" full-spectrum ones) over my head in the morning and it's been really effective for regulating my circadian rhythm. Even with little sleep, I will naturally wake up in the morning at a much more regular time.
    • al_borland 50 minutes ago
      I have been using one of those sunrise alarm clocks for around 8 years now. If I go to bed at a reasonable time, the light will wake me up naturally before the alarm actually goes off. However, if I stay up too late the effect of the light fades. I'll sleep right through the light and need the alarm. On one occasion when I must have been really sleep deprived, I slept through the light, an hour of the alarm going off, and another 2-3 hours after that.
    • neckardt 1 hour ago
      If the light turns on too quickly for me it’s super jarring and I hide under the covers. Did you find one that goes bright over the course of 30m or something? Or can you handle the quick increase in brightness?
      • hannasanarion 37 minutes ago
        Smart bulbs.

        You can make your artificial sunrise take as long as you want, and connect them to a sleep tracker so they're timed to wake you up during a comfortable phase.

        I've been doing this for 12 years, and I don't think I have ever been upset to hear my alarm since, as long as I'm home and the lights have prepared me. Lately I've even been waking up before my alarm about half the time, even though I work on a schedule one time zone east of where I am.

        It's shocking to me that it's not more popular for everybody. I guess the benefit is hard to explain.

      • al_borland 48 minutes ago
        I have a sunrise alarm clock, I think from Phillips. If I set the alarm for 8am, the light will start turning on at 7:30am then slowly increase in brightness over the next 30 minutes until 8am when it's at full brightness and the alarm goes off (which are nature sounds).

        When it first starts, it's more of a warm glow than a light. The max brightness can also be set.

            tbh as a non-user, I think stimulants are likely life improving for many (potentially most) people. what i dislike/chafe at is the insinuation that stimulants only work for people with diagnosed ADHD or only have non-recreational effects for people with ADHD. the latter especially seems to rapidly have become a folk wisdom.
      • gregoryl 1 hour ago
        Roughly, zero. Stimulants are not a fun dependency, come with a bucket list of side effects and downsides, and only mitigate one aspect of ADHD.

          ADHD treats with Lisdexamfetamine. Amfetamines, I repeat. People use this to study, to get high at parties, to be functional at work, so I really doubt there aren't patients out there abusing these drugs with valid prescriptions.
          • jplusequalt 1 hour ago
            Yes, some people will abuse their prescriptions.

                No, but if you're trying to argue that sleep therapy would be more effective for this group than non-stimulant form of medication, you need to prove this.

                Sleepy therapy (CBT-I) may be the best supported treatment for insomnia, but it's still quite shit. ~50% of people will see little to no improvement after going through therapy.

      • ctolsen 1 hour ago
        ADHD is highly treatable with medication, and any other intervention is at best mild mitigation. So how many? Amongst people with ADHD, basically nobody.

        Sun and proper sleep is certainly helpful for people with ADHD but the likelihood of them getting that is vastly increased if they’re medicated correctly.

        That is doubly important given that one of the effects of the medications, is to disrupt sleep.

        Any psychiatrist worth a damn already considers these things.

        "ADHD" symptoms can manifest for a variety of reasons, and that's why good ADHD testing involves multiple exams alongside the traditional ADHD ones to help figure out what actual issues are present.

        Also, comorbidities make this all the more complicated. Your assertion that people need "more sun" and "regular sleep" could very well be true, yet someone can still have ADHD.

          Protocols however are always changing depending on new findings. Not saying this is the case, but not considering something unknown at the time doesn't make a doctor not worth a damn.

          if that was the case the treatment wouldn't be unecessary, like I specifically wrote in the comment you are replying to.
