What Happens When You Quit Smoking?

 

Right now is a great time to quit smoking. Why? In as few as 20 minutes, you’ll start to feel the benefits.

Here we break down the changes that occur in your body within minutes, hours, days, and even years of you kicking the habit. The health benefits of quitting today may surprise you.

The effects of quitting start to set in immediately. Within 20 minutes after your last cigarette, your heart rate will begin to drop back toward a normal level.

After two hours without a cigarette, your heart rate and blood pressure will be close to normal levels again. Your blood circulation will also start to improve. The tips of your fingers and toes may start to feel warm.

Nicotine withdrawal symptoms usually start about two hours after your last cigarette. Early withdrawal symptoms include:

  • intense cravings
  • anxiety, tension, or frustration
  • drowsiness or trouble sleeping
  • increased appetite

Carbon monoxide, which can be toxic to the body at high levels, is released from burning tobacco and inhaled as part of cigarette smoke. Carbon monoxide bonds very well to blood cells, so high levels of the gas can prevent the cells from bonding with oxygen. The lack of oxygen in the blood often causes serious heart conditions and other health problems.

In as few as 12 hours after quitting smoking, the carbon monoxide in your body decreases to lower levels. In turn, the amount of oxygen in your blood increases to normal levels.

he risk of coronary artery disease (CAD) for smokers is 70 percent higher than for nonsmokers. It is the most common form of heart disease and the leading cause of death in the United States, according to the National Heart, Lung, and Blood Institute. However, just one full day after quitting smoking, your risk for CAD will already begin to reduce. Your risk of having a heart attack also starts to decline. While you’re not quite out of the woods yet, you’re on your way!

It may not be life-threatening, but an inability to smell or taste well is one of the more obvious consequences of smoking. Once you quit smoking for 48 hours, your nerve endings will start to regrow, and your ability to smell and taste will improve. You’ll soon start to better appreciate the finer things in life.

At this point, the nicotine will be completely out of your body. This means that the symptoms of nicotine withdrawal may peak around this time. You might experience some physical and emotional symptoms during withdrawal. These include:

  • headaches
  • nausea
  • cramps
  • sweating
  • anxiety
  • irritability
  • depression

This is when quitting smoking can become especially difficult. If you’re able to make it to this point, reward yourself so you feel motivated to continue. Use the money you would have spent on cigarettes to buy something nice for yourself.

Within three weeks, you’ll be able to exercise and perform physical activities without feeling winded. Stopping smoking for a couple of weeks gives your body time to regenerate and heal. Your blood circulation and heart function will improve significantly during this time. Your lungs may also begin to clear, allowing you to breathe more easily.

For most smokers, withdrawal symptoms start to subside about two weeks after quitting.

After one month without cigarettes, the cilia inside your lungs will begin to repair. The cilia are the tiny, hair-like structures that push mucus out of the lungs. Once the cilia are able to do their job efficiently, they can fight off infection and clear the lungs more easily. With properly functioning lungs, your coughing and shortness of breath will continue to decrease dramatically.

Your withdrawal symptoms will also go away completely within nine months after quitting. The length of time it takes varies depending on how long and how often you smoked before quitting he one-year mark is a big one. After a year without smoking, your risk for heart disease drops to half that of a smoker’s. This means that someone who smokes is more than twice as likely as you are to develop any type of heart disease.

A wide array of toxic substances is released in the burning of tobacco. Over time, these substances cause your blood vessels to narrow, which increases your risk of having a stroke. After five to 15 years of not smoking, your risk of having a stroke is the same as that of a nonsmoker.

Smokers are at higher risk than nonsmokers for a daunting list of cancers. These include:

  • oral cancer
  • throat cancer
  • esophageal cancer
  • lung cancer
  • kidney cancer
  • pancreatic cancer

Of these cancers, lung cancer is the most common form of cancer that affects smokers. Smoking is a main cause of lung cancer and accounts for 90 percent of lung cancer deaths worldwide.

It may take 10 years, but if you quit, eventually your risk of dying from lung cancer will drop to half that of a smoker’s. Ten years after quitting, your risk of getting other types of cancer also decreases.

End.
