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.
ADHD adult with chronic insomnia here. I usually sleep with “electronic ambient music for sleeping with delta waves”, which is the prompt I give my bedside google home before bed. I do not sleep more, but the delta waves thing seems to help me sleep deeper.
