    The older I get the more sensitive to a single poor night's sleep I become.

    The most frustrating effect is that even a few drinks in the evening (maybe over 2-3 units). Unsettles my sleep that if I'm in the process of learning something feels like it sets me back several days.

    That's not even counting the slowed processing I feel, and lower productivity the next day.

    I genuinely have to revisit old information.

    A genuine hangover from a heavy night can put me out of action for half a week!

    When I was younger I'm not sure I had many good nights sleep let alone noticed a bad one!

    I've heard that small amounts of alcohol can actually improve learning interestingly by preventing interference from events later in the day.

      I’m 49 and have all but given up on drinking. It does nothing for me except make me tired and then, ironically, mess up my sleep. On fridays I grill cheeseburgers for the family and usually have one Half-Life tall boy from Manhattan Brewery because it’s my favorite of all time but that’s about it. Otherwise, I don’t drink at all. Being tired and not sleeping well is handled perfectly adequately by my job hah.

      Can relate.

      I'm not noticing it unsettles my learning but can relate to a few drinks already upsetting my sleep. I wouldn't be surprised if my learning would be impaired by at least a bit.

      > When I was younger I'm not sure I had many good nights sleep let alone noticed a bad one!

      Being young is a blessing that way.

      I'm +35 years old by the way.

      > I've heard that small amounts of alcohol can actually improve learning interestingly by preventing interference from events later in the day.

      Do you have a source? Would be curious to look some of it up.

      • rustyhancock 1 hour ago
        I'm in a similar age bracket.

        Here is some research around the alcohol effect. What I found most surprising is the mean consumption was over 80g, since 8g of ethanol is a unit that's an astonishing mean of 10units.

        I was of the impression that the effect was around 1 unit.

      Weird responses from those two users. Ignore them
      • x______________ 17 minutes ago
        Those responses are very much valid responses to a topic that some share as a valid conversational topic on a thread about getting good sleep and learning, myself included.

        Even better, the topic is visited on part 6.2[1] of the article you're replying to.

        This type of response on the other hand, is not helpful at all and for a 14 day old account with this only post...

        Some might say you are the one worth ignoring.

      Sounds like you have a problem with alcohol, not with sleeping.
      • rustyhancock 2 hours ago
        What makes you say that?
        • elAhmo 2 hours ago
          Mentioning drinking three times (effects of drinks in the evening, hangover, effects on learning) in a single response might give an impression you like to drink.

            I mean, they sell alcohol in shops for money, and not force it on you in some government-mandated way. Which kinda tells that people in general like to drink.

              > Which kinda tells that people in general like to drink.

              No, it just tells you there is enough demand for alcohol selling to be a profitable business, not that people in general like to drink.

          • soco 1 hour ago
            The topic is drinking so they mentioned drinking, and usually people do what they like to do, and in other news water is wet - but do we judge water for being wet? So let's stop virtue signaling because it's definitely not a show of virtue. I see where religious fundamentalism is taking the world and damn if I like it.
            • Ifkaluva 1 hour ago
              I’m not religious at all, and it’s not religious fundamentalism to point out that alcohol disrupts sleep, and that this likely is the primary factor affecting the poster’s sleep.

              Also not religious fundamentalism to point out that alcohol is a known carcinogen (: that’s just science. It’s a Group 1 carcinogen, the same group as tobacco and asbestos.

    How can I explain to my 6 months old girl that we all need to sleep :D

    This is a bug in the universe! We need to sleep so that the levels of dopamine, and hormones of hunger and not hunger are at good levels, so that we can be healthy and strong, so that the immune system is stable and strong... And we need to get good sleep so that we can protect our children and be sane....

    BUT the nature decided that the kids will wake up 3-4 times per night, and you need to wake up and take care of them.

    You sleep in best case, on pauses, not more than 4-6 hours, you feel miserable, and at the same time you are THE HAPPIEST PERSON IN THIS WORLD! :)

      In my area there is a saying like "it takes a village to raise a child". i believe that a good social network is not only important for the kid, but for the parents too. it helps so much to have a partner, grandparents, aunts/uncles, who can look over the kid just for a hour or 2, so you can get your rest. And its usually fun for the kids too. Now that i have 2 kids, a loving wife and 2 families around me, i have the highest respect for all the single moms/dads out there.

        There is no nuclear family required anymore,

        My parents are the village, and the village is the law.

        As immigrants with no local network, having kids is basically putting yourself under house arrest for a decade or so. You can post bail (pay a babysitter) for occasional reprieve. I mean sure you can go do outings with kids, but for most of them, do you really want to? I know mine aren't particularly enthralled by trips to the Rijksmuseum.

        I don't think this is how humans usually raised kids...

        • ray_v 1 hour ago
          We're in the same boat. Feels like mostly our society doesn't value having children - it's by and large not a very well supported activity. Even more so if you don't have immediate family to help support you.
      • keybored 9 minutes ago
        This is why people critique the nuclear family—the degenerate village around the children that just consists of the parents, maybe grandparents at holidays. It’s a recipe for overworked adults.

      > This is a bug in the universe!

      Is it? Couldn't it be a bug in our society/economy instead? What if nature wanted us to take some naps through the day and not just one period of sleep in the night? Waking up multiple times at night wouldn't hurt too much then.

    • tariky 47 minutes ago
      I can relate to this. Got two kids and I must say if someone told me that it will be this hard I wouldn't believe it.

      Raising kids is the hardest and most fulfilling job.

    > There is only one formula for healthy and refreshing sleep: Go to sleep only when you are very tired. Not earlier. Not later. Wake up naturally without an alarm clock.

    This is very easy to say when you're not suffering from insomnia and other sleep disorders.

    • thisisauserid 3 minutes ago
      >> sleep only when you are very tired

      This flies in the face of all sleep research done at the Stanford Health Care’s Sleep Medicine Center.

      You're confusing treatment for insomnia with recommendations for general sleep hygiene.

    I am recently diagnosed with Type II Diabetes.

    The classic symptoms were unknown to me until this point when I researched them.

    I had previously blamed psych medications for the symptoms, and while they may have exacerbated them, I guess diabetes was the real root cause.

    One of the symptoms is frequent urination. And so, every night I wake up every 2 hours or so and crawl into the bathroom. It’s legitimately a huge curse.

    I don’t get enough deep R.E.M. and I remain exhausted just from the physical effort of get-up-and-go.

    It’s very frustrating and sad to think that even after I’ve got my blood glucose under control, I still have these lingering symptoms that impact my QoL.

    Eat right, kids; eat well or be cursed for life!

    • kshacker 1 hour ago
      IMO Type 2 diabetes is manageable. My father struggled with it for decades and his last few years were not great. Having those same genes, I've spent a lot of time reading and following the data. My take is that T2 is quite manageable. Even reversible, if you focus on it. "Reversible" doesn't mean a lifelong cure, but you can push out your health days by a decade.

      There are all kinds of solutions that work. High Protein, Mediterranean, Atkins, or even High Carb (the "good" kind). The breakdown usually happens in the "cocktail" of foods. Our bodies are not hybrid engines; we can not switch fuels mid-stream and expect optimal health. You have to pick a poison, let's say, a protein-based diet—and stick to it. Then exercise and intermittent fasting (IF) are force multipliers. I did strict IF for a year, but I have fallen off the wagon lately, only manage 3-4 days of IF a week. The difference in how I feel is stark.

      What worked for me was something called "Lalit Kapoor" diet — basically a WFPB/vegan approach with heavy green juicing and fasting. My failure was primarily due to social friction. My family eats very differently. Making a special effort for every single meal eventually made me start taking the easy way. I still follow it but I wish I could be 100% rather than 80% and which is where all diets fail.

    As a Spaniard I am trying to honor my ancestors and nap when I can, but man, it feels almost impossible most of the days. It could be that I am having too much anxiety/stress, too much coffee in the mornings, lack of practice, or maybe all of them. Any experiences related to learning to nap or what worked for you over here?
    • nsbk 48 minutes ago
      Fellow Spaniard here. Our ancestors were definitely onto something! I think the most important thing when it comes to napping is to show up: find a comfortable spot, use an eye mask, and set a timer for whatever time you have (I typically do something between 10 to 30 minutes). Just close your eyes and don’t open them until the alarm goes off.

      I don’t always nap, but I make sure to do so if I haven’t had enough sleep or when I’m stressed or overworked. The more work I have, the more naps I take. Three back to back meetings? 15 minutes nap for your brain to organize and process the information dump. You get the gist. Doesn’t have to be after lunch, just a few minutes when you need/have them.

      I used to do the Dali nap: find a comfortable spot, hold a spoon in your hand, and close your eyes. Once you fall asleep the spoon will fall from your hand and wake you up. That makes sure you go into hypnagogic state, great for problem solving as the brain is in a creativity sweet spot.

      The technique I use now is not strictly a nap but a relaxation technique called NSDR: Non-Sleep Deep Rest. It’s kind of a guided meditation that deeply relaxes your body and nervous system. Just 10 minutes can feel as restorative as hours of sleep. You can check Andrew Huberman's scripts or Youtube videos for a more body-hacking, science-backed vive, or channels like are Ally Boothroyd's [0] for a more spiritual take on the concept, also known as Yoga Nidra.

      I hope that helps. And best of luck with your napping, honor the ancestors!

        Thank you so much for your detailed answer! I definitely try to show up, but I am an anxious person and sometimes trying to nap makes me even more anxious. However, it is true that even when I don't manage to sleep it helps relaxing me and giving me some extra energy.

        I've also read about NSDR and wanted to try it, so having some sources is really helpful. Do you always practice it with some guided meditation or can you do it on your own? I kind of not like guided meditation. (No reason, it's just that kind of feel wrong. Probably I should just open my mind and try it more.) Thank you so much!

    • isolli 43 minutes ago
      Set a timer for 20 minutes, lie down (or at least close your eyes) and force yourself to stay motionless until the timer rings. Try to let your thoughts float freely... Sometimes it works, sometimes it doesn't, but you should try at least a few times. (And yes, maybe limit yourself to just one coffee in the morning.)
      • amunozo 24 minutes ago
        I try, but apart from the coffee (I usually take two, probably the second one interferes with my nap), I think it's the lack of consistency/practice what's making my napping difficult.

    I'm extremely sensitive to poor sleep. I also have nothing in my schedule that really prevents me from going to sleep early and sleeping late most of the time, and generally I at least achieve the former. The problem is that I have unbearable horrible nightmares every time I sleep. To the point where going to sleep is akin to going to hell itself, and I generally choose to forcibly wake myself up around like 6 a.m. just to get away from it all. I haven't really figured out a way around this.
    • mettamage 1 hour ago
      I have as a kid. It might help you. As a kid, I instinctively (and later also consciously) have trained myself to become lucid while dreaming. When I become lucid, I gain some power. Then I trained myself to be more powerful in dreams.

      For example, I can't fly, but I can (apparently) move the whole universe by a specific offset. I can also change the specific offset at a specific motion. So basically, I don't have flying powers, but I do have the powers of treating my dream like a Unity3D scene. And in that way, I can mimic flight.

      I can also turn into a monster myself, usually into a worse monster than whatever I'm facing. I have become my nightmare's nightmare at certain points.

      Nowadays though, whenever a nightmare hit I'm just unfazed. What also helps is that I let my nightmare and the creatures within it know that I am immortal. No matter what they do to me. In my dreams I am The Beginning and The End. I am all that will be there. They are there because of me. I'm essentially the only god that there is (I'm not religious but as far as my dreams are concerned, I am a god).

      That throws off quite a lot of nightmares. The ones that persist, it's fine. They can test my immortality.

      • logicprog 1 hour ago
        I've trained myself to have powers in the dream, but I rarely, fully know that it's a dream, so it doesn't really help when it's all psychological.

    I think nearly everyone should be screened for sleep apnea. The at-home test you wear on your finger is so cheap - it doesn't make sense not to do it for anyone who has any issues with sleep or tiredness in the day.

    I always thought that due to being female and a healthy weight, it wasn't something I needed to think about. I also didn't think I snored more than anyone else, so it took me years of poor sleep before a Doctor finally recommended I get tested.

    Turns out OSA also can be caused or aggravated by: the size and shape of your mouth, the position you sleep in (I have twice as many events on my back vs side), and whether you tuck your chin in near your test (soft cervical collar helped for that). There are devices that alter how your mouth rests when sleeping (easier to breathe if your front teeth are forward) but they're possibly not good for your bite. CPAP/APAP is still the gold standard for a reason.

    The coolest thing about CPAP though, is a lot of them have amazing metrics recorded if you pop in an SD card. And there's a big community built around open source software to analyze those metrics and tune the settings to minimize apnea events overnight.

    Also, a cpap with a humidifier is amazing if you're prone to nose pain / nose bleeds due to dry air.

    • weakfish 1 hour ago
      My comment is more of a complaint than a discussion so apologies, but I was disappointed recently because I did at an at home test and scored borderline. I was hopeful that it would be sleep apnea so I could go about solving my bad sleep, but a lab test showed conclusively that I didn’t have it.

      I got checked out initially because I mentioned to my sister that I didn’t recall the last time I’d woken up and felt refreshed all day, even with 8+ hours, and she said “…that’s not good, get that checked out.”

      Back to the drawing board :(

    Is the author suggesting people to have to live with going through a phase of being nocturnal? In the free running algorithm, we're supposed to sleep 15 minutes later each day until we're falling asleep at like 9AM?

    That's just incompatible with modern life right?

      I once tried an extreme version of this. I became single and I already didn't have a fixed work schedule, so other than societal convention there was no reason for me to adhere to any regular day-night cycle.

      So I tried sleeping when I was really tired, waking up without an alarm, eating when I was hungry, etc. I ignored watches, daylight and society. For context, my internal days have always been much longer than 24 hours, often finding myself going to sleep at sunrise; so I thought this was gonna be great, not having to spend an hour awake in bed.

      It was horrible. And I mean HORRIBLE. I became a zombie, even though I was sleeping more than ever. I felt deeply depressed within two days. I lost all concept of the passage of time, and could never tell how long ago something had happened. I couldn't think properly or comunicate with other people. It affected me physically too, my weight, my stomach.

      The experiment didn't last long. But I couldn't tell you how long.

    • the_pwner224 1 hour ago
      That part didn't make any sense to me either. Yes, the natural circadian cycle in a vacuum is slightly over 24 hours, but exposure to light keeps it synced to the normal 24-hour day. If you free run sleep your cycle should stay locked to 24 hours, just like it has always been with our ancestors who lived without artificial light.
    • veritat14 1 hour ago
      I believe Mathew Walker writes in 'Why we sleep' that people's natural circadian cycle varies but on average is 24h and 15 minutes. But yeah sounds pretty inconvenient for most people.
  • NolanMarrow 59 minutes ago
    I really liked the idea of "Free running sleep". Not sure how feasable would be to make it part of my routine TBH. I need to adhere to external schedules (job, family). Maybe someday I'll give it a honest try!
