How to use it
One 24-hour screen-free window a week, as a three-week test: log mood, sleep and one real conversation before and after. Keep it if it helps. The research is mixed, and it helps most for people who are struggling most.
How sure we are
P Evidence: promising. Good studies, but small or few. Use it and keep checking.
C Evidence: contested. The research disagrees. Named, so you can stop worrying about it.
