How can I improve deep sleep and fix my sleep architecture?

[Evelyn.L]

I've been tracking my sleep for months and my deep sleep duration looks terrible, always stuck around forty-five minutes a night. I wake up feeling like I never truly shut down, and my whole day feels foggy because of it. I'm starting to wonder if my pre-bed routine of reading on a tablet is secretly sabotaging my sleep architecture.

I hear you. I used to read on a tablet before bed and it wrecked my wind‑down. I started turning screens off at least an hour before bed, switched to a real book, and kept the lights low. I blocked notifications and kept a steady bedtime for about two weeks. The deep sleep portion still wandered, but on some mornings I woke less groggy and the fog didn’t linger as long.

Initially I chased the numbers as well. Then I tried changing caffeine timing and a consistent wake time. The chart still looked jagged, but the days felt clearer if I kept to the same schedule and avoided late caffeine. Not a miracle, but a small steadiness.

I tried a concrete swap: no tablet, no bright screens, cooler room, warmer blanket, and a short walk after dinner. It didn’t suddenly lock in a longer core sleep phase, but I noticed the overall sleep quality drifted a bit better and I wasn’t counting minutes in the dark as much.

Is the issue maybe not the sleep stage itself but how you wake up or what’s stressing you during the day?
