For adults who smoke and are addicted to nicotine, doing just one 30-minute session of yoga or moderate exercise doesn't make them better at controlling impulses in a computer test—even though their brains show some activity changes.

For people who smoke and are addicted to nicotine, doing gentle yoga helps reduce their urge to smoke and changes how their brain works when trying to control impulses, but working out harder doesn’t help reduce cravings—even though it gets the heart pumping more. This suggests that more intense exercise isn’t always better for quitting cigarettes.
