Doctors recommend smoking to end at the age of 40-45 because the cardiovascular system is only 15 years after the fall of tobacco. It was shared by participants at the Dallas Medical Forum.
Meredith Duncan of Vanderbilt University in Nashville and her colleagues conducted a first long-term study on how cigarette smoking and other nicotine sources affect the health of former smokers and their chances of premature death.
Approximately 9,000 people attended a study whose age at the beginning of the observation was about 27 years. Volunteers have not suffered from chronic heart or vascular diseases, tuberculosis and other lung problems and were generally in the right physical and mental state.
During the 16-year observation, it was not guaranteed that youth and good health would be protected from the effects of smoking. For example, the vast majority of heart attacks and strokes – about 70% – were among former or current smokers, for example, using one box of cigarettes a day for 20 years.
The more participants smoked the experiment, the more often they had problems with the functioning of the lungs and the cardiovascular system. Rejection of "smoke" initially had a very strong effect on their health, but over time, the rate of recovery of all indicators in standards was significantly slowed down.
Even after 16 years, doctors note, far from all the negative consequences will disappear. This means that if smokers decide, they should give up cigarettes as soon as possible.
"Five years after stopping smoking, your health has improved dramatically, with the risk of heart attack, stroke and other heart problems dropping by about 38%," Duncan said.
