Everyone is aware that cigarettes are dangerous to your health. There is absolutely not one healthy substance within the cigarettes. Starting from the tar and carbon monoxide and finishing with the nicotine.
Obviously cigarettes initially damage the lungs but overtime they affect the whole body.
They affect many parts of the body including:
The nervous system
Can the body recover if you give up smoking?
Some previous studies have shown that the risk of heart attack has stabilized about five years after quitting cigarettes, but a new study says it takes 15 years.
After analyzing the data of 8,700 people observed for decades, researchers at Vanderbilt University in Tennessee concluded that it has been necessary to spend more than a decade to remove the damage that nicotine and other chemicals in cigarettes inflict on the heart.
Heart and blood vessels quickly recover from the harm of cigarettes compared to lungs, says study author Meredith Duncan.
Cardiovascular diseases are the number one killer in all countries of the world, and one of the main factors contributing to their emergence and development are cigarettes.
“HOWEVER, WE DO NOT HAVE MUCH DATA ON WHAT EXACTLY HAPPENS TO PEOPLE WHO SMOKED CIGARETTES FOR A VERY LONG TIME”
The study covers data from two generations of people, nearly half of whom were smokers, monitored between 1948 and 1975.
Heavy smokers were categorized by people who smoked at least a pack of cigarettes daily for 20 years, of which 70% had a heart attack during the research.
Five years after they stopped smoking, the risk of heart attack was reduced by 38% compared to those who stopped smoking.
However, it should have been 16 years since the cancellation of cigarettes to restore the cardiovascular health of former smokers to the level of non-smoking health.
“For people who have been heavy smokers for a long time, there may be changes in the heart and lungs that these organs can never fully return to normal,” says Duncan.
“It is important to remember that the risk of heart attack and other forms of cardiovascular disease is certainly reduced after quitting cigarettes, and this is the main conclusion of this study.”
Some positive consequences are immediately felt.
Just 20 minutes after extinguishing the last cigarette, the number of heartbeats and blood pressure are returning to normal.
About 12 hours later, the level of carbon monoxide falls to a level that is so low that it almost cannot be detected in the body.
A week later, the risk of heart attack has been reduced because heart and blood vessels are no longer exposed to chemicals that can cause blood clots.
