Exercise Cuts Cigarette Cravings and Boosts Quit Rates, Study Finds

A new review led by researchers at Adelaide University’s ARENA centre has examined how exercise can help people quit smoking. The study analysed data from thousands of participants across multiple trials. Its findings suggest that physical activity plays a useful role in reducing cravings and improving long-term success rates. The team evaluated 59 randomised controlled trials involving over 9,000 people. These studies explored both the immediate and sustained effects of exercise on smoking behaviour. Results showed that structured exercise programs helped cut daily cigarette use by more than two on average.

Exercise also boosted continuous abstinence rates by 15% compared to control groups in trials with over 6,600 subjects. Aerobic activities, in particular, supported long-term quitting success. Meanwhile, higher-intensity workouts proved most effective at reducing short-term cravings. The review highlighted how physical activity alters brain pathways tied to nicotine dependence. Exercise triggers the release of dopamine and endorphins, chemicals that regulate mood and reward. Even single sessions of intense activity led to noticeable drops in craving levels immediately afterwards. Despite the positive outcomes, the researchers noted a lack of studies on exercise and vaping cessation. No trials have yet assessed whether physical activity helps people quit e-cigarettes or dual use of traditional and electronic products.

The findings position exercise as a low-cost, accessible tool to support smoking cessation efforts. Public health experts see its potential as a complementary approach alongside existing treatments. However, the review stresses that exercise should not replace proven pharmacological or behavioural strategies for quitting.
