I don’t adhere to these guidelines strictly, which helps when they conflict. For example, if I’m tired before my usual bed time, then the “no screen rule” goes out the window because I won’t have trouble sleeping. And when I’m not tired by my usual bed time and haven’t been looking at a screen, then I have plenty of paperbacks to keep me company (or exercise, or cooking, etc.) before I eventually get tired and fall asleep.
Practically, this means that I don’t use screen after 9pm. I usually fall asleep between 9:30pm and 11:00pm, where the median is around 10:15pm or so. I guess this variance comes from different days, days when I do a lot of exercise or little, days with plenty of sun or just a bit, etc.
