American scientists from the University of Michigan found that quitting smoking at any age provides health benefits and extends life. The research was published in the scientific journal magazine American Journal of Preventive Medicine (AJPM).
Cigarette smoke contains thousands of toxic chemicals that damage nearly every organ in the body and have been linked to numerous types of cancer, stroke, and heart and lung disease.
Experts measured the impact of smoking on life expectancy at 10-year intervals in people aged 35 to 75.
Researchers used the relative risks of all-cause mortality associated with smoking to create life tables showing the benefits of quitting smoking at different ages.
Compared to never-smokers, smokers aged 35, 45, 55, 65, and 75 will lose an average of 9.1, 8.3, 7.3, 5.9, and 4.4 years, respectively, if they continue smoking for the rest of their lives. . life.
However, if they quit smoking at each of these ages, they would avoid an average loss of 8.0, 5.6, 3.4, 1.7 and 0.7 years, respectively.
The results showed that about 10% of smokers who quit at age 65 gained at least eight more years of life than those who did not quit.
Scientists stated that those who quit tobacco at the age of 65 have a 23.4 percent chance of extending their life by at least one year, and at the age of 75, it is 14.2 percent.
Additionally, 8% of those who quit smoking by the age of 75 live at least four years longer than those who continue to smoke.
