Overview<\/h2>\n

Smoking releases thousands of chemicals into your body. The result isn\u2019t only damage to your lungs, but also your heart and many other body structures.<\/p>\n

But even if you\u2019ve smoked for many years, you can reverse these effects and experience health benefits from the first hours you stop smoking to the decades after you quit.<\/p>\n

Below are some of the many health milestones you can experience by quitting smoking today.<\/p>\n

20 minutes after your last cigarette<\/h2>\n

The positive health effects of quitting smoking begin 20 minutes after your last cigarette. Your blood pressure and pulse will start to return to more normal levels.<\/p>\n

In addition, fibers in the bronchial tubes that previously didn\u2019t move well due to constant exposure to smoke will start to move again. This is beneficial for the lungs: These fibers help move irritants and bacteria out of the lungs, helping reduce the risk for infection.<\/p>\n

8 hours after your last cigarette<\/h2>\n

Within eight hours, your carbon monoxide levels will return to a more normal level. Carbon monoxide is a chemical present in cigarette smoke that replaces oxygen particles in the blood, lowering the amount of oxygen your tissues receive.<\/p>\n

When carbon monoxide goes away, your oxygen levels start to increase to more normal levels. This increased oxygen helps nourish tissues and blood vessels that were getting less oxygen while you were smoking.<\/p>\n

24 hours after your last cigarette<\/h2>\n

By the one-day mark, you\u2019ve already decreased your risk of heart attack. This is because of reduced constriction of veins and arteries as well as increased oxygen levels that go to the heart to boost its functioning.<\/p>\n

Nicotine levels in your bloodstream have also decreased to negligible amounts at this time.<\/p>\n

48 hours after your last cigarette<\/h2>\n

At 48 hours, previously damaged nerve endings start to regrow. You may also start to notice that senses that were previously dulled due to smoking improve. You may realize you\u2019re smelling and tasting things better than you were before.<\/p>\n

72 hours after your last cigarette<\/h2>\n

Within three days after quitting smoking, you\u2019ll often find yourself breathing more easily. This is because the bronchial tubes inside the lungs have started to relax and open up more. This makes air exchange between carbon dioxide and oxygen easier.<\/p>\n

In addition, your lung capacity, or ability of the lungs to fill up with air, increases about three days after quitting.<\/p>\n

One week after your last cigarette<\/h2>\n

The one-week milestone is important not only for your health, but for your success rate in quitting smoking successfully long term. Smokers who successfully make it one week without smoking are nine times as likely to successfully quit.<\/p>\n

The chances of quitting smoking for good increase with every attempt. If you can make it to one week, you can make it for a lifetime.<\/p>\n

Two weeks after your last cigarette<\/h2>\n

Within two weeks of quitting smoking, you may start to notice you\u2019re not only breathing easier. You\u2019re also walking easier. This is thanks to improved circulation and oxygenation.<\/p>\n

Your lung function also increases as much as 30 percent about two weeks after stopping smoking, notes the University of Michigan.<\/p>\n

One month after your last cigarette<\/h2>\n

In just one short month, you can experience many health changes related to stopping smoking. One is feeling a sense of heightened overall energy.<\/p>\n

You may also notice that many smoking-related symptoms have decreased, such as sinus congestion and shortness of breath with exercise.<\/p>\n

In addition to these benefits, fibers in the lungs that help keep the lungs healthy are growing back. These fibers can help reduce excess mucus buildup and protect against bacterial infections.<\/p>\n

Three months after your last cigarette<\/h2>\n

Within three months after quitting, a woman can improve her fertility as well as reduce the risk that her baby will be born prematurely.<\/p>\n

Six months after your last cigarette<\/h2>\n

After six months of quitting, many people often notice they\u2019re better able to handle stressful events that come their way without feeling like they need to smoke.<\/p>\n

They may also notice they\u2019re coughing up much less mucus and phlegm. This is because the airways are much less inflamed without the constant exposure to cigarette smoke and the chemicals contained within cigarettes.<\/p>\n

One year after your last cigarette<\/h2>\n

After one year of quitting smoking, your lungs will have experienced dramatic health improvements in terms of capacity and functioning. You\u2019ll notice how much easier you breathe when you\u2019re exerting yourself and how much less coughing you have compared to when you smoked.<\/p>\n

In addition to these health benefits, you\u2019ll have saved a dramatic amount of money. Smoking cigarettes is expensive. If you smoked a pack of cigarettes per day, you\u2019ll have saved thousands of dollars at the one-year mark.<\/p>\n

Three years after your last cigarette<\/h2>\n

In three years after quitting smoking, your risk of a heart attack has decreased to that of a nonsmoker.<\/p>\n

Smoking not only limits oxygen flow to the heart. It also damages the lining of the arteries. Fatty tissue starts to build up, making it more likely that a person will experience a heart attack or stroke. Quitting smoking can help reverse these effects and promote a healthier heart in the years to come.<\/p>\n

Five years after your last cigarette<\/h2>\n

Five years after you stop smoking, your risk of death from lung cancer has dropped by half compared to when you smoked, according to the University of North Carolina.<\/p>\n

10 years after your last cigarette<\/h2>\n

At the decade mark, your risk of dying due to lung cancer has decreased to that of a nonsmoker. The cells that were previously precancerous are now replaced with healthy cells.<\/p>\n

In addition to decreasing the risks of lung cancer, your risk of developing smoking-related illnesses also goes down. This includes a reduced risk for cancers of the:<\/p>\n
