Human beings have an inextricable bond with tobacco. Nicotine is a type of tobacco that is often used in our country. It can accelerate the formation of dopa in the human body and promote the excitement of the human body. Therefore, when people feel tired or irritable, smoking a cigarette can relieve the pain. Some people will become dependent on cigarettes and feel particularly comfortable smoking one cigarette after another. Whether smoking can refresh one's mind depends on each person's feelings. Human beings are connected with tobacco because of nicotine. Nicotine has two major "effects". One is that it can accelerate the secretion of dopamine in the human body, making people feel excited, and the other is that it can make people addicted. These two aspects work together, like a "carrot and a stick", and their coordination is really perfect, making so many people become slaves to tobacco. What's more important is that even though they know that smoking is harmful to their health, they are still willing to do it. The addictiveness of nicotine is the fundamental reason why it is difficult for smokers to quit smoking. This addiction is more of a mental addiction. Therefore, even if you quit the physical addiction, you still have to face the more complex and changeable psychological addiction. Another effect of nicotine that we are going to discuss today is whether nicotine can actually give people a boost. The claim that smoking can refresh people is not only an illusion. Not only is it impossible for smoking to refresh people, but on the contrary, it will make people feel sleepy and more drowsy. We know that people who have just started smoking may experience smoke dizziness. This is because the oxygen content in the inhaled air is lower than normal air, causing the brain to suffer from short-term oxygen deprivation. Nicotine also has a certain anesthetic effect. Nicotine was once used for medical treatment in Europe. The reason it was later abandoned was simply that the anesthetic effect of nicotine was too limited, so it was replaced by new anesthetic drugs. But for an ordinary person, even if the anesthetic effect of nicotine is very limited, the smoker still feels it. Some people say that smoking can relieve stress. First of all, this is a false proposition. The pressure faced by everyone can be said to be objective and it will not change because of smoking. The only reason why people have this perception is the dual effects of nicotine, which is both anesthetic and stimulating. It creates a realistic hallucination in smokers, allowing them to temporarily forget stress, which is almost the same as drugs. Some people say smoking helps you think. Just imagine, if your brain is anesthetized, how can you think? The reason why people need to smoke when they are thinking is to suppress their craving for cigarettes, because at this time, if they are addicted to cigarettes, it means they cannot continue thinking. The second is to relieve boredom. Thinking for a long time is a painful, boring thing. Anyone will get bored. Lighting a cigarette one after another seems to be able to find some fun when you are bored. You can even play with a lighter when you are bored. The so-called refreshing effect of smoking is based on the fact that smoking can relieve stress and help thinking. Since smoking cannot relieve stress and does not help thinking, it is naturally impossible for smoking to have the effect of refreshing. When people feel sleepy, they will feel refreshed if they go outside and breathe some fresh air. However, if they choose to smoke at this time, the oxygen content in the air exhaled into the lungs will decrease, and when the oxygen content decreases, people will feel sleepy and drowsy. Some people like to smoke a cigarette while lying in bed before going to bed. This habit combines the hypnotic effect of smoking with subjective consciousness, becoming a fixed pattern. If this person cannot smoke a cigarette before going to bed that day, it will become difficult for him to fall asleep, or even impossible to fall asleep. |
