Writing, with a method

Each guided practice in Daylight is a writing exercise that researchers actually tested, run with the cadence they used. These posts explain where each one comes from, what the studies found, and where the evidence stops.

A note on honesty: across the research, the effects of journaling are real but modest, and they vary from person to person. A 2022 review by Sohal and colleagues found a small overall benefit and mixed study quality. So we describe the methods and their sources, and we don't promise results.
