Smoking Alters Your Immune System for Years After You Quit

Smoking cigarettes can have long-lasting effects on your immune system, even after you quit. A recent study found that the immune systems of former smokers continue to be affected for years, making them more susceptible to certain diseases.

The study, published in the journal Science Immunology, looked at the immune cells in the blood of current and former smokers. They found that even after quitting smoking, the immune system of former smokers had higher levels of certain inflammatory markers and lower levels of protective immune cells compared to non-smokers.

These changes in the immune system can increase the risk of developing chronic diseases such as cardiovascular disease, respiratory infections, and certain types of cancer. It is important for former smokers to be aware of these long-term effects and to take steps to protect their health.

Quitting smoking is one of the best things you can do for your overall health, but it is also important to be mindful of the potential long-term effects on your immune system. Talk to your healthcare provider about ways to support your immune system and protect yourself from the risks associated with smoking.
