I’ve been sleeping better for the past month or so. I attribute to more consistent bedtimes and wake times, reduced life stress and cooler bedroom temperatures. Even though summer nights here in San Diego are cool, our bedroom stays warm, and I think next summer I may return to my energy-wasting summer habit from the early 90s of sleeping with the a/c on, under a heavy blanket.
Common wisdom says you should avoid screen time before bed, but I have not found a correlation between screen time and insomnia.
