It sounds fake, but it might genuinely be your genes. Scientifically the natural tendency to sleep at specific time is called your chronotype and it's semi-genetic (it also changes with age and possibly few other factors). Not only that, it also affects your alertness: morning people usually have the highest alertness just after waking up and it gradually declines throughout the day, while evening people usually wake up with very low mental functions, but then their alertness slowly rises and hits its' peak around 5-6PM.
So if you ever wondered how it's possible that you always wake up feeling like shit, while others talk about how they're so full of energy in the morning. That's how. They're literally built different.
it requires doing it over and over again and accepting that it's gonna make you feel kinda shitty. I'm at my best by 11am. When I used to work overnight til 5am, 11am was when I woke up. When I worked bars 5-close, 11am. Now that I work a 9-5, I'm physically there at 9, but I'm useless til 11am. When I fall asleep has changed as my schedule did, for each of those schedules I was in bed at 6am, 4am and midnight respectively. But when the machinery came online has never changed: 11am.
I know this is WhitePeopleTwitter, and not a direct ask; but the easiest way is to tackle it from the wake-up time, rather than forcing yourself to try and fall asleep at 10pm.
Pick a day with few responsibilities, (e.g. Saturday ) that way you won’t be too negatively impacted if you don’t get enough sleep. Set MULTIPLE alarms to 6am to force you out of bed; proceed with your day as normal, minimise screen time and bright lights after 9pm, and go to bed at 10pm.
Make sure you keep waking up at 6 am and don’t nap/go back to sleep; brute force your body to adapt. It should work as quickly as in 72hrs.
Anyone actually reading this and having similar issue, it can get expensive but try talking with a doc to try and figure it out. Before my habits got better, i tried diet/exercise, diagnosed with sleep apnea (didn't feel better rested, but def worse if I don't use cpap), and finally got way easier to manage when I was diagnosed with depression and prescribed. Ymmv but thought I'd share my experience.
Have you tried going to sleep at 10 and waking up at 6? It sounds obvious, but you'd be amazed at how many people never do the obvious thing. Like forgetting to plug in a computer and wondering why it doesn't come on when the power button is pressed.
Some of it is genetic but mostly it's conditioning, like in the Military.
EDIT: To clarify, veterans often (but not always) wake up before dawn consistently for decades after their service. I don't really recommend it as an option, but it's proof of concept.
For a real medical answer, I was, at one point, put on GHB and a Stimulant under the theory that an issue that took 9 years to diagnose (epilepsy, did not present typically). Since I had issues with cataplexy, which is only rarely seen with other issues, this made sense. Turns out it can be a side effect of some psych meds, as I'm also bipolar.
GHB knocks you out in moments, and you'll wake up 4 hours later. Time for the second dose. 4 more hours. Like fucking clockwork. It was the only time in my life I was consistently on time anywhere I've ever worked. Wasted in a Walmart auto shop.
Then stimulants (amphetamine analogue) were supposed to keep a narcoleptic awake during the day.
As others have said, it's simply a matter of discipline and getting used to it. But that doesn't necessarily mean you'll become a morning person. How you wake up and when you wake up are two different things. I'm a morning person in that I wake up easily, but I go to sleep at 1 and wake up at 9.
OK, so what you want to do is stay awake for atleast 20 hours, sleep for like 5 hours then wake up, do this for a while then pick a time to go to bed, now you gotta drink some sleepy time tea, set a few alarms and fall asleep, you should sleep for about 8 hours, and wake up refreshed, now repeat this every night until you don't need the tea.
You gotta overload your circadian rhythm to reset it.
It helps to establish a routine for going to bed. For example, set a nightly reminder on your phone 15-30 minutes before bedtime that it's time to wind things down. Don't have anything caffeinated after 5 pm or so.
Adjust the times at which you eat, and make sure those times are consistent. Sleeping habits will follow way more easily if you adjust eating times along with them.
Ooh, I have an answer that works. Get really fucking drunk over the course of a couple of hours starting around 8pm. Then take a moderate sleeping pill. You might need to train for some years, first, to not wake up with a hangover.
Source: wake up between 530-630am naturally on weekends.
ITT people find reasons it's not their fault they don't sleep at night when statistically speaking most of them actually just need to find the self control to turn off the fucking screens at night and let your body find its natural rhythm.
