Maybe it won't help in any way, but when I want to sleep, I open asmr videos on YouTube and try to relax. In fact, it also helps me to turn off the lights and remove all social networks, because they are very stressfull 😳I'm not sure if this will help, but you can turn off the light and think about something good by preparing a cold pillow and blanket. It's harder to fall asleep in a stuffy room...
