Smoking is not refreshing

Whether smoking or not, people seem to have a common understanding: smoking refreshes the mind. Therefore, many people are used to lighting a cigarette when they are working, believing that this can prevent sleepiness and relieve fatigue. In fact, it is a misunderstanding that smoking is not refreshing.

Tobacco contains nicotine, a chemical component, which can act on the central nervous system, make people feel relaxed and happy, and produce a sense of comfort. But this effect is short-lived. Medical researchers pointed out that the main effect of smoking on the central nervous system is to first excite and then suppress. After the short-term pleasure produced by smoking, people will soon feel tired and sleepy. To eliminate this kind of fatigue and sleepiness, we have to continue smoking, which leads to addiction. Studies have shown that people who smoke for a long time will suffer from impairment of thinking ability and intellectual activities, and will have symptoms such as neurasthenia, headache, insomnia and memory loss.
