The Science Behind a 3-Minute Cognitive Sprint
In productivity psychology, task resistance is highest in the first 120 to 180 seconds of undertaking an ambiguous assignment. Once you push past the 3-minute threshold, the brain begins producing dopamine as it detects initial progress, transitioning into focused concentration.
Using a dedicated 3 minute timer acts as an artificial forcing function: by bounding your initial commitment to a mere 3 minutes, you sidestep feelings of overwhelm and harness positive momentum to power the rest of your workday.
