Doctors recommend giving up smoking at the age of 40-45, because the cardiovascular system is only 15 years after the fall of tobacco. This was shared by participants at a Dallas Medical Forum.
Meredith Duncan of Vanderbilt University in Nashville and her colleagues conducted the first long-term study on how smoking and other nicotine sources affect the health of ex-smokers and their chances of premature death.
Approximately 9,000 people participated in the study, whose age at the start of observation was about 27 years. Volunteers have not suffered from chronic heart or vascular diseases, tuberculosis and other lung problems, and were generally in good physical and mental condition.
In the 16 years of observation, it was not guaranteed that young people and good health are not protected from the effects of smoking. For example, the overwhelming majority of infarcts and strokes – about 70% – were among smokers or smokers, using, for example, a box of cigarettes a day for 20 years.
The more experimental participants smoked more, the more common they had problems with the functioning of the lungs and the cardiovascular system. The refusal of "smoke" initially had a very strong effect on health, but over time, the rate of recovery of all indicators in the norms was considerably slowed down.
Even after 16 years, doctors note, far from all the negative consequences disappear. This indicates that smokers, if they decide to do so, should give up cigarettes as soon as possible.
Five years after quitting smoking, your health is greatly improved. The risk of getting a heart attack, stroke and other heart problems decreases by about 38%, "Duncan said.
