stimulus control · after midnight · the way back
Richard Bootzin's rule from 1972 is the most boring effective thing in sleep medicine: the bed is for sleep, and if you can't sleep, get up, do something quiet in dim light, and come back when you're sleepy. The American Academy of Sleep Medicine rates stimulus control a Standard treatment for chronic insomnia, its top grade. Night's door only appears after midnight, and it doesn't count toward the round. It ends it.
Light, screens and effort at 1 a.m. all push sleep later — a two-week inpatient study found evening reading on a lit screen delayed sleep and suppressed melatonin compared with print. An app that's honest about that has to make itself easy to leave: warm, dim, short, and with a door. Five slow breaths, the screen goes dark, and nothing here tries to keep you.
Stimulus control is a treatment for insomnia, tested over weeks in clinics, and the door is a five-breath exit — not the treatment, the manners. The screen-light study is twelve people, tightly controlled. Night cannot be paper; it can be warm, dim and short after midnight, and say so.
After midnight a door appears at the edge of the street. Five slow breaths in the dark and the city puts itself away: the screen dims, the rain goes quiet, it stops. Phone face-down ends it too.
