Smoking Alters Your Immune System for Years After You Quit

According to a recent study published in the journal Science Immunology, smoking can have long-lasting effects on the immune system, even after you quit. Researchers found that the immune system of former smokers continues to exhibit changes for up to 30 years after quitting.

One of the key findings of the study was that certain immune cells, known as macrophages, were altered in former smokers in a way that made them less effective at fighting off infections. This impaired immune response could potentially increase the risk of developing respiratory infections and other illnesses.

Additionally, the study found that smoking-induced changes to the immune system were associated with an increased risk of developing autoimmune diseases, such as rheumatoid arthritis and lupus. These findings highlight the importance of quitting smoking as soon as possible to minimize the long-term effects on your immune system.

It is never too late to quit smoking and improve your health. If you are a current smoker, consider talking to your healthcare provider about strategies to help you quit for good. Your immune system will thank you in the long run.
