Just one cigarette changes the way a woman's brain works

Swedish scientists from the University of Uppsala traced the effects of cigarettes on female brain The nicotine content of just one tobacco product already makes it difficult to produce estrogen.

It is well known that women have a harder time quitting smoking than men, although, in general, they smoke less often. And now Swedish scientists have received an answer to the question of why this can happen, studyfinds.

Observations have shown that one cigarette already contains enough nicotine to affect the thalamus. It is this area of ​​the brain that is involved in the production of the hormone estrogen.

But more importantly, the thalamus is responsible for regulating human behavior and emotional background. Like nicotine, other narcotic drugs have a direct effect on the thalamus, which contributes to physical and mental addiction.

That is why women are more likely to get addicted to cigarettes if they start smoking, and it is much more difficult to give them up.

In the course of this study, its authors for the first time observed how the mechanism of estrogen production in a woman's brain is blocked. They were especially surprised that this effect is achieved with the help of only one dose of nicotine contained in a cigarette. This is another reason for people to give up a very harmful habit.
