Smoking Alters Your Immune System for Years After You Quit

Research has shown that smoking can have a lasting impact on your immune system, even after you quit. A study published in the journal Science found that the effects of smoking can persist for years, altering the way your body responds to infections and disease.

Smoking is known to weaken the immune system, making individuals more susceptible to illnesses such as the flu, pneumonia, and respiratory infections. But even after quitting, the damage done by smoking can linger. The study found that certain immune cells in former smokers behaved differently than those in non-smokers, indicating a long-lasting impact on the immune system.

Researchers believe that this altered immune response could contribute to an increased risk of certain diseases, including autoimmune disorders and certain types of cancer. It underscores the importance of quitting smoking as soon as possible to protect your immune system and overall health.

If you are a current smoker, it’s never too late to quit. Talk to your healthcare provider about strategies and resources to help you kick the habit and improve your immune system function for years to come.
