It’s hard to stop smoking. Understanding what immediately happens to your body when you stop smoking, however, will help you kick that habit to the curb for good. The moment you put down your cigarette, your body is already going through positive changes. Just 20 minutes after you quit, your heart rate will return to normal. After two hours, both your heart rate and blood pressure levels will return to normal — and this is when the nicotine begins to fade out of your system. Your withdrawal symptoms typically begin between two and 12 hours after your last cigarette, and this is, admittedly, the hard part. Nicotine withdrawal will usually reach its peak about three days after you quit, meaning you’ll experience headaches or nausea, as well as crabbiness. However, at this point the carbon monoxide levels in your blood will have dropped back to normal. After that, if you can defeat the cravings, you have only good things to look forward to: one to nine weeks after quitting, your coughs, shortness of breath, or burning lungs during physical activity will begin to decrease. Years later, your risk of heart disease as well as your risk of various cancers (including lung cancer) will be half that of a smoker’s risk. Fifteen years after stopping your smokes, your risk of heart disease is equivalent to that of non-smokers. And if you stop smoking before the age of 30, you’re very likely to live the life of someone who has never smoked before — unless you’ve smoked extensively and done irreparable damage to your lungs that can lead to chronic obstructive pulmonary disease (COPD).
