Quit Smoking: The greatest method to shield friends, family, coworkers, and other people from the health hazards of secondhand smoke exposure is to stop smoking. One of the most crucial things smokers may do to lower their risk of cardiovascular disease is to give up. Your chances of getting various diseases decrease and your health almost immediately begins to improve. Not only will you save money, but your secondhand smoke will no longer influence people around you. Compared to non-smokers, smokers have a lifetime risk of lung cancer of up to 22 times higher. More than two thirds of lung cancer fatalities worldwide are attributable to tobacco smoking, which is the main cause of the disease.

Quit Smoking: Alzheimer’s disease


Quit Smoking: The study clarifies why smokers have an increased risk of Alzheimer’s disease and age-related cognitive impairment. Researchers at the Washington University School of Medicine in St. Louis found that smoking effectively causes the brain to age prematurely because people’s brains gradually lose volume with age. There is substantial evidence to suggest that smoking raises the risk of dementia in individuals. The risk of vascular issues, or issues relating to the heart and blood arteries, is increased by smoking. Alzheimer’s disease and vascular dementia, the two most prevalent types of dementia, are also associated with these vascular issues. A recent analysis of 37 studies revealed that current smokers had a 40% increased risk of developing Alzheimer’s disease and a 30% increased risk of developing dementia in general when compared to never smokers. Previous studies’ analyses revealed that the danger might be substantially higher if you are a smoker.


Quit Smoking: Brain damage

We are all aware of the harmful effects of smoking cigarettes, including how it can harm our hearts, lungs, and even cause cancer. But did you realise that it also has an impact on your brain? According to a recent study, smoking causes irreparable brain damage that might lead to permanent brain shrinkage. The results, which were published in the journal Biological Psychiatry: Global Open Science, showed that while stopping smoking can stop additional brain tissue loss, it won’t cause the brain to grow back to its pre-smoking size.

Professor of Psychiatry Laura J. Bierut at the university stated, “Until recently, scientists have overlooked the effects of smoking on the brain, in part because we were focused on all the terrible effects of smoking on the lungs and the heart”. “But as we’ve started looking at the brain more closely, it’s become apparent that smoking is also really bad for your brain.” The researchers examined de-identified information on 32,094 people’s brain volume, smoking history, and genetic susceptibility to smoking for the study.

They discovered a connection between smoking history and brain volume, smoking history and genetic risk for smoking, and genetic risk for smoking and brain volume. Moreover, there was a dose-dependent relationship between smoking and brain volume: A person’s brain volume decreased in proportion to the number of packs they smoked every day. Regretfully, it appears that the shrinkage cannot be reversed. Researchers discovered that the brains of those who had given up smoking years before to now remained permanently smaller than those of those who had never smoked.

The researchers ascertained the sequence of events: genetic predisposition leads to smoking, which leads to lower brain volume. They did this by using a statistical technique called as mediation analysis. “It is bad, and it sounds bad,” Bierut remarked. “An rise in age is correlated with a decrease in brain volume. As our population ages, this is crucial because smoking and ageing are two major risk factors for dementia.” – QUIT SMOKING
