How Does Smoking Affect your Lungs

There is no question about smoking, and its deadly impacts on the human body, the chief among them is smoking affecting your lungs. The fundamental job of your lungs is to transfer oxygen-rich blood from the air you breathe into the rest of your body and to remove carbon dioxide as waste when you exhale. Damage to this important organ can lead to serious illness and death. Cigarettes can injure lung tissue, making it difficult to function properly and increasing the risk of life-threatening diseases¹⁰⁰. As such, the dangers of cigarette smoking cannot be undermined¹⁰¹.

How does smoking affect your lungs?

The lungs begin to be damaged as soon as you take your first puff. Over 7,000 chemicals are contained in each puff of cigarette smoke¹⁰². When you inhale, the smoke almost immediately reaches your lungs. The poisonous substances are subsequently carried throughout the body via the blood. Tobacco smoke contains carbon monoxide, a dangerous chemical that robs your blood of oxygen. This deprives all of your organs of the oxygen they require.

The effects of smoking on your lungs¹⁰³ are numerous. Some of these effects include the following:

• Smoking damages your airways and the little air sacs (alveoli) in your lungs, which can lead to lung disease.
• COPD, which encompasses emphysema and chronic bronchitis, is one of the lung diseases induced by smoking¹⁰⁴.
• Smokers are 12 to 13 times more likely than nonsmokers to die from COPD.
• The majority of lung cancer cases are caused by cigarette smoking¹⁰⁵.
• Also, if you have asthma, tobacco smoke can either cause or exacerbate an attack.

How can you protect your lungs from smoking¹⁰⁶?

One of your body's filtration systems is your lungs, which takes in air from the atmosphere, supplies oxygen to the blood for circulation, and eliminates excess carbon dioxide. This delicate balance is disrupted when tobacco is inhaled.

The greatest method to protect your lungs is to never start smoking tobacco, but if you are already a smoker, the sooner you quit, the better. Quitting smoking instantly reduces your risk of laryngeal cancer; lung cancer is lowered by 50% ten years after quitting, and mouth and throat cancers are decreased by 50% five years after quitting.

How to reverse the damage done¹⁰⁷?

Stopping smoking is one of the most efficient ways to reverse the damage done. When you stop smoking, your whole health improves. After stopping smoking, the risk of lung cancer decreases dramatically. Furthermore, only 12 hours after stopping smoking, your blood carbon monoxide level returns to normal. Of course, this allows more oxygen to reach your organs.

What kind of support can I receive when quitting smoking¹⁰⁸?

One of the most significant steps people can take to enhance their health is to stop smoking. This is true independent of their age or length of the smoking experience. So, make sure to:

• Consider the positives
• Make a strategy for quitting smoking
• Take into account your eating habits
• Alter your beverages
• Recognize when you have a strong desire for smokes
• Obtain assistance in quitting smoking or join cessation programs
• Get your feet moving
• Make non-smoking acquaintances
• Make a list of reasons why you want to quit

The last thing on the list of things you need in life is a smoker's lungs. Avoid it at all costs as it is unpleasant, to say the least. Quit smoking now and get all the support you need along the way!
