Current and Former Smokers Have More Pain
/By Pat Anson, PNN Editor
There are many good reasons to stop smoking. Within hours, your heart rate and blood pressure will drop, you’ll cough less and feel more energy. Within a few months your lung function will start to improve. And after 20 years, your risk of dying from lung disease or cancer will be about the same as someone who never touched a cigarette.
Unfortunately, one thing that may not improve is your pain. According to a large new study in the UK, former smokers report higher levels of pain than people who never smoked, and their pain levels are similar to people who still continue to smoke.
Researchers at University College London (UCL) analyzed health data from over 220,000 people in the UK who were asked to report how much pain they experienced during the previous 4 weeks and whether it interfered with their work.
After adjusting for other health factors such as anxiety and depression, current and former daily smokers were more likely to report bodily pain compared to people who never smoked. The difference was small, but considered significant. Surprisingly, the association between smoking and pain was highest in the youngest group of smokers (aged 16 to 34).
The study was observational and did not establish a cause-and-effect relationship between smoking and pain. But researchers say their findings, published in the journal Addictive Behaviors, suggest that regular smoking at any age results in more pain.
“We cannot rule out that there is some other difference between former smokers and never smokers that is causing these surprising results, but we have to consider at least the possibility that a period of daily smoking at any time results in increased pain levels even after people have stopped smoking,” said lead author Olga Perski, PhD, a research associate in UCL’s Department of Behavioural Science & Health.
“This may be due to negative effects of smoking on the body’s hormonal feedback loops or undiagnosed damage to body tissues. This is certainly an issue that needs looking into.”
Another possibility is differences in personality. People who take up smoking may handle the psychological stress of illness differently than non-smokers or have a lower level of pain tolerance, which makes them feel pain more acutely. A large study in Norway, for example, found that smokers and former smokers were more sensitive to pain than non-smokers, who had a higher pain tolerance.
Regardless of the reason, smoking is linked with many negative health consequences.
“The possibility that smoking may increase lifelong pain is another important reason not to take up smoking in the first place,” said Perski.
Studies have also found that smoking increases your chances of having several types of chronic pain conditions, such as degenerative disc disease.
A 2011 study of over 6,000 Kentucky women found that those who smoked had a greater chance of having fibromyalgia, sciatica, chronic neck pain, chronic back pain and joint pain than non-smokers. Women in the study who smoked daily more than doubled their odds of having chronic pain.
