If you quit smoking, the body will begin to recover almost immediately after the last cigarette.

What Exactly Happens When You Quit Smoking?

After 20 minutes from the last cigarette your pulse and blood pressure return to normal. The circulation in the extremities improves and delivers blood-rich with oxygen to them. Then, 8 hours after the last cigarette, carbon monoxide is completely eliminated from the body. It’s replaced with oxygen that the cells need to function normally.

Namely, after 24 hours, the risk of heart attack is reduced, as the number of heartbeats and blood pressure begins to drop. If you quit smoking for 48 hours, the nerve endings that were dead are starting to regenerate and your sense of smell and taste returns.

After two weeks to three months after the last cigarette, the circulation continues to improve and you begin to breathe more easily. The lungs produce less mucus and function better. Your physical strength for activities improves as you have less breathing problems.

If you quit smoking for a whole year, the risk of a heart attack decreased by 50 percent. Between 5 and 15 years of quitting, the risk of stroke is the same as for non-smokers.

And if you manage to quit smoking for 10 years, the risk of lung cancer will drop significantly. The risk of getting other types of cancer – mouth cancer, esophagus cancer, throat cancer, kidneys and bladder cancer is also reduced. Although you have not smoked for 10 years, the risk of lung cancer is still higher than for those who have never smoked.

Why Is It So Hard To Quit Smoking?

Why, despite everything we know about smoking, we still smoke? It’s because of the nicotine. Nicotine causes addiction and it is the main cause that we continue to smoke. Nicotine is an organic compound that is found in leaves of some plant species but is mostly consumed by tobacco. Although nicotine is not carcinogenic in itself, it indirectly prevents the body from destroying potential carcinogenic cells.

When we try to quit smoking, the brain reacts by creating symptoms that make us feel bad and thus instigates us to consume nicotine. For most smokers, it is not possible to quit smoking easily. The recovering process is difficult and unpleasant, but if you are determined to quit smoking, you will do it.
