Smoking affects the brain

The experts of the Institute of Edinburgh analysed the long-term consequences of Smoking and found a correlation between a bad habit and thinning of the cortex. Specifically it is in the human body is responsible for the main cognitive functions such as memory and perception.

Such conclusions scientists have produced, examined data 244 men and 260 Dame, the Central age was 73 years. In the number of volunteers came in smokers, those who quit Smoking and never smoked people. All participants were first surveyed in childhood, in 1947. Researchers also used the data being collected at the time not so long ago occurred interviews and analysed the data scan of the brain, according to Science World Report.

Experts have learned that those who smoke, and former smokers aged 73 years many areas of the cortex was thinner than those who never smoked. However, quit rates was observed orientation to the partial renewal of the thickness of the cortex of the brain, according to "Rossiyskaya Gazeta". With the aging crust is thinner, but Smoking accelerates this process. The result of the thinning of the crust, according to researchers, is retained for many years after a person quits Smoking.

A well-known precedent: after Smoking a single cigarette from a resident of our planet increases heart rate, increases the pressure, constrict blood vessels, over the years have blood clots. Therefore, the risk of unexpected death grows several times. Additionally, in consequence of the area to constrict the Airways, is activated sputum, develops a cough, are formed more frequent asthma attacks.

Nicotine from cigarette smoke induces the fragmentation and multiplication of cancer cells in the lungs. Additionally, this habit increases the likelihood of developing cancer of the pancreas, disturbs the circulation of the retina, impairing vision. Slightly less damage Smoking causes reproductive system, leading to impotence and infertility.
