I must have noise to go along with going to sleep. Usually thats an audio book or long-form video essay type YouTube videos. I wear one earbud to bed if I’m sleeping at night with my girlfriend or just blare it from the TV if I’m sleeping alone during the day (rotating shift). I feel like when I don’t have engaging audio and I’m trying to sleep I can’t quiet my mind enough to sleep. A fan or random ambient noise isn’t enough for me.
I always put on one of Vinny Vinesauce’s vods from his Fullsauce channel when I go to sleep. He just relaxes me so much I’m normally out within less than 5 minutes whereas in complete silence I could end up taking half an hour or multiple hours to fall asleep.
