It’s important to your heart and lungs to quit smoking and improve your overall health. Find out how cigarettes affect your health and learn what happens to your body from the moment you decide to quit smoking.
Only 20 minutes after quitting, your heart rate and blood pressure will drop closer to normal levels. Nicotine harms the insides of blood vessels and reduces the amount of oxygen the heart receives, making the heart beat faster and the damaged blood vessels work harder. This very short period of time allows your body to begin to repair itself.
Within two hours of smoking your last cigarette, your peripheral circulation will improve. Peripheral veins and arteries are located in the arms, hands, legs and feet and supply oxygen to the body. As your body rids itself of the chemicals in cigarettes, your hands and feet will start to feel warmer.
Around 12 hours after quitting smoking, the level of carbon monoxide in the blood drops back to normal. Carbon monoxide replaces oxygen in the blood cells making it so that your heart is not getting enough blood. Once the carbon monoxide is gone, there is more oxygen in your body.
After one day, your risk of heart attack drops. People who smoke have a 70% higher chance of having a heart attack because of the cardiovascular dangers associated with smoking. Smoking also increases your risk for blood clots, another major issue related to heart attacks.
By day three, there is no more nicotine in your body. Each time you smoke, the nicotine your body needs to get that “buzz” is amped up and requires more frequent cigarettes. This cycle leads to addiction.
Two weeks after quitting circulation and lung function improve. As stated above, cigarette smoke damages your blood vessels. As time progresses, they will begin to repair themselves. Even in a small amount of time, like 14 days, your body is becoming more healthy.
1 to 9 Weeks

The risk of developing heart disease is two to four more times as likely in smokers. This risk decreases by half when you quit smoking.
2 to 5 Years
Between two and five years after quitting, the risk of developing mouth, throat, esophagus and bladder cancers is reduced by half. Women’s risk of cervical cancer is also decreased.
After five years, your risk of having a stroke drops to the same risk levels as nonsmokers. Smoking accelerates the development of blood clots, which are a factor in strokes. Quitting alleviates this stressor.
