As scientists have found out as a result of recent studies, smoking is not only harmful to health, but also negatively affects the brain and human intellectual abilities.

The research itself was conducted at the Scottish University of Aberdeen. They involved 465 people aged 64 years. Half of them were heavy smokers. All the subjects had to undergo a series of psychological tests designed to assess memory and intellectual abilities. The results were subsequently compared with the results of tests conducted with the same people, but in 1947 at the age of eleven.

The conclusions that the scientists came to after the test are disappointing. Smokers significantly lag behind their non-smoking peers in all types of tests conducted. Over the years, their memory, perception, logical thinking, and ability to reproduce information have deteriorated.

Scientists are not yet ready to explain why smoking has such a negative effect on the functioning of the human brain. One of the proposed versions is that the action of cigarette tar and nicotine causes extreme sensitivity of cells to the effects of free radicals. The latter are toxic compounds that appear in redox processes inside the cell. In addition, cigarette tar increases the content of free radicals throughout the body.

Deterioration of brain function due to prolonged work

Researchers from the UK have published the results of their work, according to which a person who works more than 40-45 hours a week has much lower rates of brain activity than those whose work schedule does not exceed the norm.

The study involved more than 2,200 volunteers aged 40 to 50 years. The results showed that when the load is exceeded, the indicators of memory, thinking, and cognitive activity significantly decrease. Presumably, these indicators in old age lead to disorders of brain activity, up to dementia.

Scientists believe that long–term work leads to chronic fatigue, which, in turn, manifests itself in depressive states, sleep disorders, digestive disorders, and decreased immunity. And on this basis, a wide variety of diseases often grow. In particular, it is quite possible that it is chronic overwork that stimulates the development of senile dementia.
