Long-term Impact of Smoking on Immune System
New Study Shows Smoking Weakens the Immune System
Despite the decline in smoking rates since the 1960s, it still remains the leading cause of preventable death, with over 480,000 deaths each year attributed to smoking. While doctors have long warned about the links between smoking and serious health issues such as lung cancer, heart attack, and stroke, a new study has shed light on another reason to kick the habit.
Recent research has revealed that smoking not only immediately reduces the body’s ability to fight infection, but it also increases the risk of chronic diseases involving inflammation, such as rheumatoid arthritis and lupus. The study, which involved examining blood samples from 1,000 healthy individuals aged 20 to 69, found that smoking has a significant impact on immunity.
The group of participants, equally divided between men and women, had their blood samples exposed to common microbes such as E. coli bacteria and the influenza virus, with their immune responses measured. The study aimed to analyze how various factors, including age, gender, genetics, lifestyle, socioeconomic issues, and dietary habits, affected immunity.
The results showed that smoking has nearly the same effect on the immune system as important factors like age and gender. Even when smokers in the study quit the habit, their immune responses only improved somewhat and did not fully recover over time. It was also observed that the immune system began to reset gradually after quitting smoking, signaling that it’s never too late to quit.
Furthermore, the study also explained why conditions such as chronic lung disease, or COPD, can still develop in individuals who have quit smoking. This information serves as another compelling reason for smokers to quit and for non-smokers to avoid taking up the habit.
The findings from this study highlight the detrimental impact of smoking on the body’s immune system and provide further motivation for individuals to quit smoking for their overall health and well-being.
