How long do smokers take to recover completely?



A new study found that a smoker's heart needs 15 years to recover completely after quitting smoking.
Previous studies suggest that the risk of stroke in previous smokers stabilizes within five years, but the new study shows that it can take up to 3 times the time.
The study, which will be presented next week at the American Heart Association conference, is the first of its kind in the analysis of abandoning cases in advanced stages.
After analyzing 8,700 people over the age of 50, researchers from Vanderbilt University found that smokers' hearts require more than a decade to get rid of life-threatening damages, including nicotine, tobacco, and many other chemicals in cigarettes.

At the same time, Meredith Duncan, PhD student at the Vanderbilt University Medical Center, said that the heart and blood vessels are the fastest to recover from the effects of smoking. The lungs are another story.
Duncan and his team in Nashville, Tennessee, wanted to explore how long the body needed to quit smoking to show real health effects.
To investigate, the team collected data analyzed by the Framingham Heart Study, which began in 1948 and continued until 1975, which involves two generations of people (almost half of the smokers).
The "Smokers" team was classified as people who smoked the equivalent of a pack of cigarettes per day for 20 years. Smokers had a 70% risk of having a heart attack. After 5 years, the risk dropped 38% after quitting smoking.
But it took them almost 16 years after quitting, to return the level of risk of cardiovascular disease to normal.

In fact, blood vessels are the main benefit of quitting smoking. Only 20 minutes after a smoker stopped smoking, the heart rate falls and blood pressure returns to normal.
After 12 hours, the levels of carbon monoxide in the blood stabilize, while the risk of heart attack decreases after about a week, because the heart and blood vessels "eliminate chemicals in cigarette smoke that cause plates be more viscous,.
"Even for bad smokers, the benefits of quitting can not be overestimated," Duncan said.
Heart disease is the only murderer in all countries of the world, including the United States and Britain, while rates are rising due to obesity, stress, lack of exercise and ingestion of unhealthy meals.
In recent years, some have been dedicated to smoking electronic cigarettes, a questionable and badly considered practice, where it has been shown that their harm to the human body is not different from that of common cigarettes.
