  1. Quite accurate... by acxr+is+wasted · · Score: 3, Interesting

    Seems to be pretty accurate in predicting my 3 p.m. nap after my 4-6 a.m. sleep schedule. Too bad it can't tell me what time this afternoon I'll wake up after I go to bed now.

  2. glitch by Anonymous Coward · · Score: 3, Interesting

    There's a glitch of some sort. It said that I would be noticeably tired at 16:30 and most tired at 16:30, but the graph clearly showed otherwise. The tips for tiredness also has a problem as the words aren't showing up properly.

  3. unrealistic form options (for me at least) by mardoen · · Score: 5, Interesting

    Their form to enter the time I wake up in the "mornings" is flawed. No option after noon (I usually rise at 1-3 pm, go to sleep at 4-5 am).

    Guess they didn't think about students. Or unemployed programmers...

    This also applies to hangovers; I learnt to reserve blowouts for during the week from an old hand. Keep your Saturday morning head clear!

  5. Naps? by skraps · · Score: 5, Interesting

    Their system doesn't account for naps. I generally sleep from 3am-9am, and 6pm-8pm. Work for the man during the day. Take a nap to refresh yourself. Work for yourself at night. I've used this system on and off for a few years, and it works well.

      The rule of the thumb I've always learned is: don't take a nap after 4 pm. Of course that rule assumes that your usual sleep schedule is something like 10pm-6am, and that you are napping due to fatigue and want to return to that sleep schedule as soon as possible.

      MEEEE TOOOO. My exact sleep schedule right there. Works like a charm.

    Exactly. I work nights, and therefore I sleep from around 11:am to 7:pm. This just proves that this is either another goofy-ass, slapped-together website, or just a marketing gimmick. Nothing to see here.

  7. Odd by ItMustBeEsoteric · · Score: 2, Interesting

    For me, it basically says that I am never alert. I did a 4am-9am sleep pattern, which is actually being on the generous side for me: I normally sleep more like 4 hours. I had bad insomnia for years, and just "got used to" sleeping little I suppose. Somewhere after 4-5 hours I will wake up without an alarm, and I won't be "exhausted" all day...In fact, sometimes I'm not tired by 4am, but get myself off to bed anyway.

    Apaarently, this means that I am in fact never alert. I have to agree with other /.-ers who have cried "marketing scheme."

  8. the results weren't far off by Cruciform · · Score: 4, Interesting

    The site is obviously an ad, but they did a fairly good job at predicting my low points in the day.

    At 2:30 in the afternoon, I'm usually completely wiped out, and occasionally I'll end up face down on the keyboard.

    I used to sleep so much better when I was physically active. Now, it's get up, commute, sit like lump at desk all day, become unmotivated due to typical work day, get home, sit around the home or at the computer all evening because I've got no energy.

    Life was better when I went rollerblading every day, before my knees went to hell.

    I bet exercise a few times a week would be a hell of a lot more effective than that little caffeine pill.

    And someone should do a study on what professions tend to get better sleep. I bet a construction worker will have insomnia 10 times less than a desk jockey.

  9. Take a Nap... by Anonymous Coward · · Score: 1, Interesting
    Winston Churchill took an hour's nap each day during the war: he said that was what kept him going.

    Every afternoon, roundabout 1:45, I begin to feel sleepy. If I immediately nap then I will automatically wake up after 20 minutes feeling refreshed and alert. If I do not nap, then I drag the remainder of the afternoon.

    As the nap begins I start to dream about music, then the usual dream images, then I fall into a deep sleep, only to wake at the 20-minute time. No alarm required!

    It is important that I not be disturbed during the nap, so I wear 33-db earplugs and disconnect the phone.

  10. Using your sleepy time of day for diagnostics by Tiburana · · Score: 5, Interesting
    One the things that those who practice ancient Chinese medicine believe is that certain types of energy run through meridians in the body, and are tied to individual organs or groups of organs. Supposedly, each energy has a peak time and a nadir time. For instance, the lung energy has its peak from 3-5 am and then the large intestine energy peaks from 5-7 am.

    Practitioners use this diagnostically by associating when people have a major dip in their energy level to show them which energy needs to be strengthened, which may indicate a pathology in that associated organ.

    The individual energies correlate to five elements that are each expressed by particular flavors, seasons, colors etc. and they will recommend a person increase their exposure to the things associated with the element where their energy is weakest.

    It would be interesting to see if the times of people's energetic nadir as predicted by this system or observed empirically did correlate to physical or emotional issues as predicted by this ancient system.

    I have to tell you I have been pretty skeptical learning about it all but there are a lot things that correlate with accepted western medical theory and some intuitive things that are just dead on, whether I believe in it or not.
