There are some behaviours that help like:
-Downloading a blue light filter (eg f.lux) (avoiding device use entirely in the hours before sleep is better but lets be realistic)
-Not using the bed for activities such as studying, laptop use, eating etc
-exercising during the day
-limiting caffeine to early in the day
-having a before-sleep schedule
-avoiding sleeping in
-some find it useful to write anything keeping them on edge in a journal before bed
-seeing bright blue light soon after waking
-drinking cold water after waking to make you feel more awake
-timing your sleep/wake time so you wake up at the end of a sleep cycle
Hope some of this is vaugely useful
To add to the lists of useful tips by miniturtle.
-Don't look at the clock if you have trouble sleeping. The anxiety generated from "Oh no it is x time, I need to sleep NOW!!!" will make you sleep later because your body is stressed.
-Don't look at blue light at least
2 hours before your sleep time (The time when your body hits the bed)
-Be
actually tired when you hit the bed. It is common sense, but many people set these predefined times to sleep and they ain't even tired
-On the thing with caffeine, I think the effects like 6 hours or something like that so plan it wisely. The same applies to energy drinks as well.
-If you can't sleep, just get up and exercise like push-ups, pull-ups, starjumps, squats, etc. This will fatigue your body and make it easier for you to sleep.
-Don't do other stuff in your bed besides sleeping. If you do stuff like reading your phone in bed, your mind will associate your bed as looking at your phone.
-Make sure you bed is as dark as possible. This helps your body sleep so blackout curtains, no lights on nearby etc
-Moving your alarm clock away from your bed like another room or your door. This gets you out of bed and less likely to go back in to bed. You can combine this with having multiple alarm clocks like a wind-up clock with a phone alarm
-Trying getting a different alarm like those sensor ones with increasing light levels as it approaches wake up time
-Open the blinds when you get up ASAP. Your body wakes up to sunlight (This IMO is better then the blue light suggested by miniturtle)
-Go camping for a ~1-2 week to reset your circadian rhythm
-Check to make sure your bed's temperature is just right and not too hold or cold. As this can affect duration and quality of sleep.
Extra note, it takes ~1-2 weeks to set this schedule so be patient and keep it consistent.
Or you end up like me, where your now trying to fix it but get it broken due to your family's nightly activities
