🛡️ What happens to your immune system when you quit
Immunity isn't a special power. It's plain work your body does every day — and quitting removes one thing that gets in its way.
When the season for catching colds arrives, you become a little more aware of how fragile a body is.
Someone coughs on the train. More people are off sick at work. You wake up and your throat hurts slightly at the back. At times like that, people think about sleep, food, temperature.
Tobacco doesn't usually get invited into that conversation.
But smoke is not unrelated to immunity.
The CDC lists a positive effect on the immune system among the health benefits of quitting. Smoking burdens many organs and affects the body's responses involved in infection and inflammation. Quitting works in the direction of reducing that unnecessary burden.
