On the theme of videos, there is a group of people on YouTube who do what's called "ASMR" (pseudo-scientific name, not in the textbooks, etc.)
If you've ever felt drowsy in a barber's chair, that's what they do.
It's really not for everyone, for a variety of reasons. It is however worth a try if you can keep an open mind. As it's videos, I get best results when I switch the screen off and just listen, or download the audio and just listen to that in bed - beats having to say "Oh, drowsy now," stand up, switch off the puter, go upstairs and get into the sack.
Try channels by "percussivethoughts" or "relaxing roleplays" (she changed her user name), Heather Feather, Gentle Whispering, amalzd, UKASMR, visualsounds1.
For the record, I don't give a darn about makeovers, manicures, cranial nerve exams or the like, but a relaxing female voice is, well, relaxing. Also tends to cut in front of the voices in the back of your head which keep you awake.
It may leave you cold and

, or it may put you to sleep, YMMV.
