How Exercise Boosts Your Chances of Quitting Smoking by 15%

A new review led by researchers at Adelaide University’s ARENA group has examined how exercise can help people quit smoking. The study analysed data from 59 trials involving over 9,000 participants. It explored both immediate and long-term effects of physical activity on smoking behaviour and cravings. The review found that aerobic exercise improves long-term success in quitting smoking. Higher-intensity workouts, in particular, help reduce short-term cravings. A single session of intense exercise can cut nicotine cravings by a moderate to large amount right after the activity.

Exercise programs also led to a drop in daily cigarette use, with participants smoking over two fewer cigarettes per day on average. For those trying to quit, structured exercise increased the chances of staying smoke-free by 15% compared to non-exercisers. This finding came from trials with more than 6,600 subjects. The researchers noted that exercise affects brain chemicals like dopamine and endorphins, which play a role in reward and mood. These changes may help counteract nicotine dependence. However, the review highlighted a lack of studies on how exercise impacts vaping cessation, calling for more research in this area. While promising, exercise is seen as an extra tool rather than a substitute for proven methods like nicotine replacement therapy or behavioural support.

The findings suggest exercise could be a useful, low-cost addition to smoking cessation efforts. Its accessibility and broader health benefits make it an attractive option for public health strategies. But further studies are needed, especially on how physical activity might help those trying to quit e-cigarettes.
