habitstacking

Habit stacking is a behavior-change technique in which a new habit is tied to an existing one, using the established routine as a cue. By pairing a small, specific action with an already automatic behavior, it aims to increase the likelihood that the new habit will be performed consistently.

The idea relies on the concept that cues trigger routines in the habit loop. The term was popularized in recent years by self-help and productivity literature, notably by James Clear in Atomic Habits, though similar concepts have appeared in behavioral psychology for decades.

To implement habit stacking, first identify a reliable daily habit you already perform (the anchor). Then decide on a new habit that can be done quickly and has a clear, specific cue. Create a simple plan that ties the two together, for example: after I brush my teeth, I will floss for one minute; after I sit down at my desk, I will write one sentence. Keep the new habit small and measurable to reduce friction, and adjust the pairing if the anchor habit changes or if motivation wanes.

Benefits include low cognitive load, rapid adoption, and potential compounding effects as multiple new habits are added over time. Limitations include dependence on the reliability of the anchor habit, potential to backfire if the cue becomes inconsistent, and reduced suitability for complex or high-effort behaviors.

Common examples include stacking a hydration habit after waking, inserting a short stretching session after checking email, or reading one page after a coffee break. It is related to concepts such as implementation intentions, habit loops, and keystone habits.
