Smoking how long

In addition, your lung capacity, or ability of the lungs to fill up with air, increases about three days after quitting. 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. 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.

This is thanks to improved circulation and oxygenation. Your lung function also increases as much as 30 percent about two weeks after stopping smoking, notes the University of Michigan. In just one short month, you can experience many health changes related to stopping smoking.

One is feeling a sense of heightened overall energy. You may also notice that many smoking-related symptoms have decreased, such as sinus congestion and shortness of breath with exercise. 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. Within three months after quitting, a woman can improve her fertility as well as reduce the risk that her baby will be born prematurely.

This is because the airways are much less inflamed without the constant exposure to cigarette smoke and the chemicals contained within cigarettes. After one year of quitting smoking, your lungs will have experienced dramatic health improvements in terms of capacity and functioning.

Smoking cigarettes is expensive. In three years after quitting smoking, your risk of a heart attack has decreased to that of a nonsmoker. Smoking not only limits oxygen flow to the heart. Cigarettes contain a lot of known toxins including carbon monoxide, a gas present in cigarette smoke. This gas can be harmful or fatal in high doses and prevents oxygen from entering the lungs and blood.

When inhaled in large doses in a short time, suffocation can occur from lack of oxygen. After just 12 hours without a cigarette, the body cleanses itself of the excess carbon monoxide from the cigarettes. Just 1 day after quitting smoking, the risk of heart attack begins to decrease.

Smoking raises the risk of developing coronary heart disease by lowering good cholesterol , which makes heart-healthy exercise harder to do. Smoking also raises blood pressure and increases blood clots, increasing the risk of stroke. Smoking damages the nerve endings responsible for the senses of smell and taste.

In as little as 2 days after quitting, a person may notice a heightened sense of smell and more vivid tastes as these nerves heal. While it is healthier to have no nicotine in the body, this initial depletion can cause nicotine withdrawal.

Around 3 days after quitting, most people will experience moodiness and irritability, severe headaches , and cravings as the body readjusts. As the lungs heal and lung capacity improves, former smokers may notice less coughing and shortness of breath.

Athletic endurance increases and former smokers may notice a renewed ability for cardiovascular activities, such as running and jumping. Nine months after quitting, the lungs have significantly healed themselves. The delicate, hair-like structures inside the lungs known as cilia have recovered from the toll cigarette smoke took on them.

These structures help push mucus out of the lungs and help fight infections. Around this time, many former smokers notice a decrease in the frequency of lung infections because the healed cilia can do their job more easily. As mentioned above, the improvements you may see with COPD will depend on the severity of your condition. Those with mild to moderate COPD may see more positive changes, while people with severe COPD could experience a leveling off of their earlier gains or even a slight reversal.

If this happens, it doesn't mean that you're going backward but rather that you need ongoing COPD treatment to further slow the progression of the disease.

Weight gain is another common concern among ex-smokers. One meta-analysis showed an average increase of roughly 8. There is some variation among individuals, but if you're concerned about gaining weight, try taking steps to curb eating and increase exercise. While you can't necessarily undo the structural damage smoking causes to your lungs, your lung function can improve significantly once you remove cigarettes from the equation.

This is often the case for people with COPD who have stopped smoking. After several years without a cigarette, their rate of lung decline can resemble that of non-smoker—meaning their rate of decline, when considered alongside their age, is no different from someone who has never smoked before.

While there is no product or quick fix that will clean or "detox" your lungs after smoking, quitting can still improve your overall lung health. Your lungs are self-cleaning and will begin to heal themselves after you stop smoking though the extent to which they will heal depends on your overall health, how long you've smoked, and your existing lung damage.

If you're concerned about your lungs, there are steps you can take to protect them. These include:. Over time, the health benefits of smoking cessation appear to continue:.

Your long-term health outlook depends on a variety of factors, like your overall health, how long you've smoked, what age you quit, and your other health-related behaviors.
