Smoking affects the brain area that is critical for memory. According to The Daily Mail, because of smoking in the hippocampus accumulated calcium. This was proven by a study of approximately 2,000 people. Volunteers were asked to undergo cognitive tests and brain scans.

It turned out that such deposits were more common in smokers or diabetics (one-fifth of volunteers). This explains the relationship between smoking and dementia. Calcification of cerebral vessels and toxins in tobacco smoke lead to a decrease in cognitive abilities, experts say. In avid smokers, the risk of dementia is almost doubled. In general, the presence of a bad habit increased the risk of developing dementia by 50%.

And cigarette smoke directly affects the muscles, showed another study. Scientists have conducted a study in mice. Rodents were exposed to cigarette smoke for 8 weeks. The study showed: in rodents, due to smoke, the number of small blood vessels in the muscles of the legs decreased.

As a result, the muscles did not receive enough oxygen and nutrients.

According to the researchers, this can adversely affect the metabolism, the level of activity and provoke the development of chronic diseases, for example, diabetes or chronic obstructive pulmonary disease (COPD). Experts do not yet know which of the 4000 chemicals contained in cigarette smoke damage the muscles. Scientists plan to continue research.
