What can I do to fix my sleeping schedule?

Go to bed 30 minutes earlier then the last night so night one go to bed (no phone no laptop no tv) 30 minutes before you did last night and do the same until you have a set bedtime and stick to it

Everyday try and slowly move back towards a better sleeping schedule. That will you won't end up feeling overtired and wanting to have a nap in the day. Try and get up a little earlier each day and going to bed a little earlier, until your sleep is at a better schedule than it was before.

For about a week, have a desired bed time/wake up time. The day before you start try doing more than usual, maybe a walk after dinner or an hour outside doing something. This way your body will feel tired sooner, try not to eat a big meal before bed! Lay down about a half hour before your desired bed time. Try listening to soothing music or a fan, whatever you do to fall asleep. Now it won't be easy at first but keep up the same routine every night and it'll stick soon enough. Now for your wake up time, no snooze button! The first time you hear your alarm jump up and start your day. It won't be easy at first but again it'll click in no time. No napping through the day! Your body will want to sleep whenever since it's out of whack, but stay active throughout the day so as not to sleep. After a few days of this your sleep schedule will be fixed:)

Train your body to get the rest that it needs. Set a time to wind down and relax. Hopefully this helps.

I think setting time aside half an hour before I have to sleep just to relax helps soothe my brain from working in overdrive when I am trying to fall asleep. Some activities I do is reading books that don't evoke strong emotions or quietly reflecting on my day

Try to go asleep for example 15 minutes earlier or later every week depening on what your goal is about your sleep. Melatonin pills(natural sleeping hormone pills) will also help.

Try counting backward like count 100 and take a breath then say i will sleep well today...take anotherbreath and count the next no. Mostly people can sleep in the 90ies it self helps me a lot...i hope it helps you too

Get into a routine. Get 8 hours of sleep. Go to sleep around the same time everynight. Try to not be on your phone or watch tv

You can try to take natural sleep remedies such as tea or milk or a bath before you want to slep and work on it

The circadian rhythm which decides whether a person is an early bird or a night owl is innate in us and transferred genetically tracing back to cavemen for evolutionary reasons. However, if you want to alter your internal clock disrupted by internal or external (avoidable) stimuli, you could follow through these. 1. Stay awake for 18 hours straight, if you want to change the timing you typically want to sleep at. This is supposed to reset your internal clock with no hindrance from the previous sleep cycle. 2. Avoid siestas. If you can't avoid them, try to time them anywhere between 20 to 60 mins. Anything beyond that would complete a sleep cycle which includes REM. This just makes you more alert and disrupts your sleep cycle more. 3. Don't use a clock while on bed. Don't check the time no matter how long it seems you've been awake. 4. Pick a topic and read / think / listen to it. This works miraculously. Use the said topic ONLY when you want to sleep. Initially it won't make any difference. But as your brain is tuned to a channelised reaction towards the aforementioned topic, you'd automatically sleep as time goes on.
