Doctors recommend quitting 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 the Dallas Medical Forum.
Meredith Duncan from Vanderbilt University in Nashville and her colleagues conducted the first long-term study of how smoking and other nicotine sources affect the health of ex-smokers and the possibility of their early death.
About 9,000 people participated in this study, whose age at the beginning of the observation was around 27 years. Volunteers do not suffer from chronic diseases of the heart or blood vessel system, tuberculosis and other lung problems and generally in good physical and mental conditions.
During 16 years of observation, adolescents and good health are not guaranteed to be protected from the effects of smoking. For example, the majority of infarcts and strokes – around 70% – are among former or current smokers, using for example one box of cigarettes a day for 20 years.
The more participants in smoking experiments, the more common they have problems with the functioning of the lungs and cardiovascular system. The rejection of "smokey smoke" initially had a very strong effect on their health, but over time, the rate of recovery of all indicators in the norm slowed down.
Even after 16 years, the doctor noted, far from all the negative consequences disappeared. This shows that smokers, if they decide to do so, must immediately hand over their cigarettes.
"Five years after quitting smoking, your health improves. The risk of heart attack, stroke, and other heart problems drops by around 38%," Duncan said.
