> What does spending 8 hours in bed but only sleeping for 5.5 hours mean specifically

It means that the TV is in the bedroom.

>So, the title is misleading. It means you should lie in bed for 8.5 hours in order to actually be asleep for 8 hours.

No, the title is not misleading.

Sleep is not just the time you're actually asleep. It's the whole time that you're in bed.

If you are in bed for only 8 hours a night, do you account for the times you woke up mid-sleep and went to have a piss, for example?


>A professor I collaborate with at Penn State named Orfeu Buxton says that 8.5 hours of sleep is the new eight hours. In order to get a healthy eight hours of sleep, which is the amount that many people need, you need to be in bed for 8.5 hours.

So, the title is misleading. It means you should lie in bed for 8.5 hours in order to actually be asleep for 8 hours.

That said, this article has plenty of good insight and is well-written.


> I’ve always required television to get to sleep, and I’m not a good sleeper.

These two statements are correlated. Television in your bedroom makes you a worse sleeper, and you can immediately improve your sleep quality by removing it and keeping your room as dark as possible. I was skeptical of this, but after a month of insomnia, I went to a sleep lab for a consult and took all of their advice. I'm still not an amazing sleeper but it's been a huge improvement.


>I often wake up in the middle of the night

That might not be that unnatural as sleeping for 8 hours straight:

>without an alarm I can sleep 12 hours.

This was the case for me until I started (a) going to bed shortly after dark and (b) leaving the blinds open.

An really incredible thing happened: I started feeling tired around dusk, and awake at dawn.

Note that it's best to avoid/limit screens and LED lights past dark.


> I get up at 4:30 AM every day and work at something until about 8 PM and then am in bed by 8:30

I do me too (since I was about 30). Not exactly 04:30 though — sometimes I get up at 02:00, sometimes 06:00 ... working 4 - 10 hours, then siesta for about 1 hour.

I find that with a 30 min or 1.5 hours? power-nap/siesta, my brain "resets" and I can stay concentrated 10 - 12 hours a day.

Edit: Now I see that you're in bed 8:30 PM. I first read 8 AM and assumed that that meant a power nap. — Seems I get tired a lot sooner than you.


>> You can't sleep in an RV?

> During certain hours while parked in a residential area.

The hours you are talking about are night hours.


> 45 minutes later, I’m tired

I think you're tired to start with, just go to sleep. I realized this with myself and others. Some kind of marketing that "unwind and relax" means you have to watch some TV when sleep will actually bring you more enjoyment.

You can always trade those 45 minutes when you wake up for a movie if you actually want to watch one - and you'll enjoy it more.


> As you age you might find you need more sleep.

This is very true for me, much to my surprise. I used to get by on 3 to 4 hours every night but that seems to have really caught up with me. If I don't get 8 hours minimum now I'm woozy the rest of the day.


> I go to bed when I’m completely exhausted at +1am

is that bad? the time of sleep I 'need' seems to correlate with the amount of work I did that day

when i'm truly relaxing/vacationing i can even hit 5 hrs of sleep and wake up without an alarm, but after a particularly difficult work day, i may even need 8 hours to feel like i've slept that night


> Instead of snoozing for an hour,

I've never understood the snooze button. Either it's time to get up or it's not.


> or you're just a light sleeper, but generally waking up several times a night is not common.

Especially if the TV is on


> You could take this one step further and just say NO devices or TV at night or after 7pm, period.

I've done that before and it didn't make any difference for me. If I read a book on a screen or on paper before bed, it doesn't seem to matter, as long as the light is 1850K.


> Sleep deprived actors by definition cannot correctly judge their ability to be sleep deprived.

What is that supposed to mean?

Especially 'by definition'??

Your body gives you plenty of feedback for sleep deprivation.


> They could go to bed at a decent hour but usually stay up late & catnap instead.

My wife (as a Japanese salarywoman) is perpetually tired, but still stays up late watching TV/SNS. Why? "If I went to bed early, my whole life would just be work and sleep"


> you aren’t spending your nights sitting at home watching Netflix

You are though, most nights too, because there might be a million options but a normal person needs to rest and recharge at home a lot of the time.


>Some people delude themselves into thinking that 5 hours a night is all they need and then sleep 14 hours on Saturday.

Oooh that sounds familiar.


> There are some humans who only need 5 hours of sleep

Define "need". Also, citation needed.

Just because you can get away with it and live, doesn't mean it's the best move.


> But that extra time spent sleeping is time spent not being awake to do things. So the overall number of useful hours is the same either way?

Am I the only person that likes sleeping and dreaming? If I were to suddenly find sleep impossible and unnecessary, I would consider that a reduction in my quality of life.
