There's a lot of talk about music while working, but the effect of music during the break itself gets skipped over. Research shows that listening to music you like during a break, separate from the break itself, speeds up the return to focus afterward.
That's because music can shift your mood quickly. Instead of ending a break with a tired, scattered mind, a few minutes of familiar music brings you back to a more settled place.
Deliberately listening to music for a few minutes on a break, instead of scrolling your phone, makes a small but real difference.
