Exercise Cuts Nicotine Cravings and Boosts Quitting Success, Study Finds

A new review led by researchers at Adelaide University’s Alliance for Research in Exercise, Nutrition and Activity (ARENA) has examined how exercise affects smoking habits. The study analysed data from nearly 9,000 participants across 59 trials, exploring both short-term cravings and long-term quitting success. The findings reveal that exercise, even in single sessions, can cut nicotine cravings by a moderate to large degree. Higher-intensity workouts proved particularly effective, reducing urges immediately after activity and for up to 30 minutes later. Over time, regular aerobic exercise was linked to better long-term abstinence rates.

Exercise also helped those who didn’t quit entirely. Participants in the reviewed studies smoked, on average, over two fewer cigarettes per day when engaging in physical activity. The research suggests this happens because exercise alters brain chemicals like dopamine and endorphins, which play a key role in reward and mood—both tied to nicotine dependence.

The review highlighted a 15% higher chance of maintaining abstinence among exercisers compared to non-exercising controls in trials involving over 6,600 people. However, the authors noted that exercise should support—not replace—existing cessation methods, such as medication or behavioural therapy. One gap remains: no trials have yet tested whether exercise could help people quit vaping or reduce dual use of cigarettes and e-cigarettes. The study underscores exercise as a low-cost, accessible tool for smoking cessation, offering both immediate craving relief and long-term benefits. Public health strategies may increasingly incorporate physical activity alongside traditional methods, though further research is needed on its role in vaping and dual-use behaviours.
