The World Health Organization (WHO) designates 31 May of each year as the World No Tobacco Day (WNTD). This year, Hong Kong Council on Smoking and Health (COSH) has launched a Smoke-free Publicity Programme with the theme of “Join Hands for a Tobacco-free Hong Kong” to encourage public to support for the Smoke-free Sportswear Day on 31 May  by wearing sportswear and keep exercising to create a supportive social environment for smoking cessation and promote a healthy as well as smoke-free lifestyle in order to foster the society stepping towards Tobacco Endgame.

Smoking is harmful to health. It increases the risk of fatal diseases and produces secondhand smoke which harms others’ health as well. In view of this, COSH has prepared a seven-day smoke-free diary to encourage smokers to quit smoking as soon as possible, and motivate non-smokers to support them for smoking cessation in order to build the smoke-free Hong Kong.

Exercise helps relieving stress

When you exercise, your brain releases hormones, such as endorphins and dopamine which help improving your emotion. Dopamine evokes reward pathways in the brain that are similar to those induced by nicotine, thereby balancing off the unpleasant experience with pleasure, easing tension, improving blood circulation and quality of sleep.

Exercise can help with weight control

When you stop smoking, your senses of taste and smell will be resumed, appetite will be increased and metabolism will be reduced. It is not surprising that you may experience weight gain if you do not have a balanced diet. You can stay fit with a healthy diet and sufficient exercises to burn calories.

Exercise can reduce cravings to smoke

Exercise can help distract you from tobacco cravings and reduce their intensity1. When a craving hits, carry out 10 to 15 minute exercise with moderate intensity can help you overcome it more easily2. Running is a good way to train willpower. The training process can also improve cardiopulmonary efficiency and health. Study showed that running could help smoke cessation and reduce smoking. Exercise performance will also be improved after quitting smoking.

Practicing yoga can help achieving a balanced status both physically and mentally. By practicing different yoga postures and controlling the breath, fresh air goes into the lungs so as to relieve stress, erase negative emotions and may aid weight control. According to a randomized clinical trial, yoga increases the odds of successful smoking abstinence by 37% when compared to general wellness classes.
