No, early risers also go to bed when they're tired and wake up when they're done sleeping.
Having to get up at a time that doesn't suit you due to external constraints is something that can affect anyone.
It's just that early risers get tired earlier (and fast) and then often wake up quickly, fully awake. My brother has always been like this.
I'm a night owl. I get tired more slowly, go to bed later, and take a while to fully wake up too.
It seems to me there is a difference in metabolism as well as the time we get tired. Early birds are like sprinters, fast but short distance. Night owls are more like marathon runners, not so fast but keep going longer. I don't have scientific evidence for this, it's simply how it appears to me.
Or the early risers wake up fully awake because The Early Bird Catches The Worm hop hop quick quick jog to wake up, while the night owls can't be arsed with such motivational slogans and peacefully take their time. Not very different from what you're saying, just trying to detail it.
Ah, the annoying confusion of Virtue with having an early riser metabolism.
When I was choosing a secondary school for my son, there was one that pushed "being early" as some kind of moral crusade. Despite evidence that teenagers don't actually work well with that. We did not apply to that school.
Are you sure that's the right way around? I'm a night person and I have to use alarms and stuff to be able to wake up at the right time, Because I tend to stay awake late into the night. I only wake up when I'm done sleeping at the weekends, when I don't have other obligations in the morning, such as work
Work is my bane. It is somewhat of a choice for me, as I have a 1.5 hour leeway, but I want to be at home having personal time in the evenings, not working
I'm generally an early riser, and I just go to bed early and (generally) wake up a little before my alarm. Even if I go to bed late I wake up at around the same time (even though I might like to sleep in)
I don't think that early risers are primarily due to external constraints hold.
My theory is that your subconscious knows you have to wake up at a fixed time and that's extra stress, even if it wakes you up before the alarm. As you're saying, it even cuts into your sleep time.
One point in favor of this theory is that even I, a night owl, manage sometimes to wake up before the alarm on the rare days that I do need to wake up early on.
It happens even on prolonged vacations. So I don't actually have to get up at any particular time (my partner does) so I don't really buy the stress theory, it feels more like a pretty fixed circadian rhythm in regards to when I'm tired/awake - as I can push the rhythm but it takes a fair chunk of days. I imagine like adjusting to a new timezone.
I would really love to have the Sleep ability the protagonist from The Long Dark has. Unless they're fully awake, as long as they're a little tired they can sleep until fully rested.
I've long assumed it's probably due to people who'd do bad things with any sort of useful, "I'd like to go to sleep in the next 15 min, oh and no side effects if the fire alarm goes off in 30 min" kinds of drugs that they aren't a common OTC item.
I just automatically wake up after about 7.5 hours. I hate alarms and it wrecks my entire day if I sleep any less than 6.5 hours.
I can rise early without an alarm just by sleeping early.
The stupid article doesn't link the actual paper and I'm lazy to search for it but I wouldn't be surprised if this is a correlation-not-causation situation, since a lot of unskilled work does in fact require rising early while a lot of intellectual work has flexible hours.
Night people tend to go to bed when they're tired and wake up when they're done sleeping.
Early risers either use an alarm or go to bed / wake up at fixed (i.e. forced) times, mostly due to external constraints.
Is the difference really between scheduled sleep and sleeping when you feel like it?
