People who successfully quit smoking are more satisfied with their lives and feel healthier, both one year and three years afterwards, than those who continue to smoke, a new study found.
Dr. Megan Piper, from the University of Wisconsin School of Medicine and Public Health in the US, and her team look at whether quitting smoking can improve psychological well-being.
The authors assessed overall quality of life, health-related quality of life, positive versus negative emotions, relationship satisfaction and occurrence of stressors among 1,504 smokers taking part in a smoking cessation trial in the US.
Smoking status and quality of life were assessed at both one year and three years post-smoking cessation.
While some smokers have concerns that their quality of life may deteriorate if they stop smoking, the authors found that smokers who quit successfully, long-term, experience no such deterioration due to quitting.
In fact, they see some noticeable improvements. Specifically, compared with those who continued to smoke, quitters scored higher on measures of overall quality of life, health-related quality of life and positive emotions, both one year and three years on.
They also felt they had fewer stressors by the third year.
"This research provides substantial evidence that quitting smoking benefits well-being compared to continuing smoking," the authors concluded.
"Smokers might believe that quitting will decrease life satisfaction or quality of life - because they believe it disrupts routines, interferes with relationships, leads to a loss of smoking-related pleasure, or because cessation deprives them of a coping strategy.
"Our findings suggest that, over the long-term, individuals will be happier and more satisfied with their lives if they stop smoking than if they do not," they added.
The study has been published online in Springer's journal Annals of Behavioural Medicine.
