Smoking cigarettes is really bad for you because it messes up your immune system. Even if you quit smoking, your body might still be at risk of getting sick for years afterward. This study from CNN shows that smoking can make it easier for diseases to attack your body, even long after you’ve stopped smoking.
The researchers looked at blood samples from a bunch of healthy people to see how smoking affects their ability to fight off infections. They found that smoking, along with things like your weight and certain viruses, can make a big difference in how well your immune system works.
Here’s the deal: Smoking messes with two important parts of your immune system – the quick but not-so-precise part and the more targeted one that remembers threats. Even if you quit smoking, the effects on the second part can stick around for a while.
This study is important because it confirms what experts have suspected for a long time – smoking isn’t just bad for your lungs, it messes with your whole body’s ability to stay healthy. So, if you smoke, quitting is the best thing you can do for your health. And even if you’ve already quit, it’s good to know that your body can still recover over time.
