Why is it when you sleep for 10-12 hours you end up more tired throughout the day than if you had 8 hours of sleep?
In: Biology
Hormones. The longer you sleep, the more “relaxing” hormones your body releases. If you sleep for 10 hours, you have more hormones (such as prolactin and melatonin) than you would have if you slept for 1 hour.
Maybe the Matrix was on to something. We’re built like a battery, once it gets charged up to 100%, any additional charging actually depreciate the lifespan of the battery.
The short version is you don’t… or at least, not really. If you sleep 12 hours when you normally sleep 8 hours, there’s probably a reason. Typically, it’s because you either DIDN’T get your normal sleep, or are ill, or recently changed sleep schedules. Sleeping 10-12 hours is your body trying to play catchup and re-adjust, and it can’t really do that in a single day.
I doubt you’d actually feel better if you “only” had 8 hours sleep than if you had 10-12. Your head can get used to sleeping < 6 hours a night, but your body remembers the debt. As soon as you let your body begin to recover, your head will notice the change and become aware of what it was concealing from itself.
Usually because you were tired to start with, which is why you needed 12 hours sleep in the first place.
Wait some people get 8 hours of sleep?
I can’t help wondering why there are still shift systems like this. Surely it would be better for there to be a night shift, early shift etc
Why do I see this same question every single day in here? While when I ask a question my thread gets removed by admin saying “this question was already asked…”, and my question was asked not yesterday, but like a year ago
After a normal sleep you are dehydrated already. Sleeping longer makes you feel tired, since dehydration makes you feel tired.
I do 2 earlies 5.45 start, 2 lates, 1500 start and then 2 night 9pm-6am. Then get 4 off. I’m ALWAYS tired.
Just to elaborate on this, as people have already answered. If you wake up in the middle of a dream your head will be messed and you feel tired still. If you are awoken in the middle of a deep sleep phase you will feel very drowsy. As we alternate between sleep states, being waked up in the REM phase will do that to us, we are supposed to wake up as we leave the REM, and instead of going into deep sleep we wake up.
That’s why if you want to get very little sleep, deciding to sleep for 3 hours, you wake up and feel a mess, while sleeping 4 hours, will have you wake up and feel you got some rest and made you able to work again.
And if you usually wake up after 6 or 8 hours your body has ajdusted itself to that cycle, then when you sleep 2 hours longer, you wake up in the middle of a sleep phase.
