the article states 7 hours is the minimum, but I seem to need a lot more. they state, if you can sleep after the alarm clock goes off, then you should sleep more. So, what if you get 8.5 hours of sleep but you still could sleep, after the alarm clock goes off? there should be some upper limit, maybe 9?

The article states 7 to 9 hours.

I recommend a 'Sleep' app on your phone. I set it to 7am and it'll wake me up anywhere from 6:30-7, depending on my sleep cycle. Never felt drowsy on 6:30 days.

  This works well for me (I use ‘sleep cycle’) but doesn’t solve my inability to actually get tired and go to bed at night.

    Have you tried avoiding screens an hour or two before going to bed? Fill that time with reading or listening to podcasts.

      podcasts are awesome - we're kinda in a golden age for it.

      Does the Kindle still count? I heard that it is different from computer screens because the light is backlit, not directly shown into your eyes.

        A Kindle should be fine, preferably without backlight however.

  How does an app predict your sleep cycle? Do you have the keep phone on you?

    It tracks your sound or movement (either via the microphone or the accelerometer) as you sleep to determine your sleep cycles. You set a baseline of typical sleep for 5 days, and after that the app can predict when to wake you up.

Unless there is extend of stress or body injury that needs sleep to continue the recovering process, or other medical situation occurs, a healthy body does NOT require more sleep than 6-7 hours, because it is not about sleep's length but the quality of REM sessions of your sleep. If you happen to to push your sleep over 8.5 hour, you are entering into another REM session (that you don't need) that's why when you wake up in the middle of from it, you feel very tired. But try to wake up precise 6.5 hour after you fell asleep and you will feel very refreshed (given you had interrupted good night sleep)
