-wash your face with something icy
-eat something healthy before you go to bed
-keep yourself hydrated, too, because you'll feel sick when you wake up if you don't
-drain your phone battery before it's time to go to bed so that you won't be on it all night
-try not to work on anything creative about an hour before you go to bed, because creative ideas are the things that keeps your brain awake the most
-don't fall asleep listening to something, because it will keep waking you up
-try to make your room as dark as possible
-make yourself comfortable
-don't overthink getting to sleep if possible, because again that's what will keep you awake
-try to do something other than watching TV or being on a device (reading a book sometimes will make your eyes tired)
-stay away from caffeine before and right after sleeping
-stay away from medication before and after sleeping
-don't give up when trying to fall asleep, because chances are you'll fall asleep without knowing it
