First of all, let's talk about why coffee can lift people's mind. When people are awake, a substance called adenosine monophosphate gradually accumulates in the brain. It will actively bind to receptors that slow down brain activity. The more it binds, the more sleepy people become. While people in the process of sleep, will gradually reduce this binding, adenylate concentration gradually decreased. Caffeine is structurally similar to adenylate and can compete with adenylate and bind to these receptors, so there are fewer receptors that really bind to adenylate, so people don't get tired. In addition, caffeine can promote the secretion of epinephrine, which can also make people in a state of excitement. So there will be the phenomenon that we often say, "you will feel much better after drinking coffee."

In this state, caffeine can continuously improve people's attention and sharpness, and help people accomplish routine or boring tasks. After drinking one or two cups of coffee, people can see things more clearly and distinguish colors even more clearly at night. Coffee helps people ignore the decentralized stimuli in the environment, making us more focused and more likely to lose ground and be persuaded.

Why is it easy to be persuaded when you are focused?

Because persuasion is actually a complex process, it involves six steps, if you need to convince the other person, you need to let the other person-- (1) receive the message; (2) pay attention to the message you want to send; (3) have at least some understanding of the message you give; (4) accept your conclusion; (5) maintain a new attitude (even if you no longer persuade the other person, the other person will side with you)

(6) use new beliefs to guide your behavior in the process, if a step is hindered, persuasion may not be achieved. We are not easily persuaded because we are absent-minded and do not listen carefully, and we may not be able to complete (1) (2) (3) (4). Then why are we talking about persuasion? Caffeine forces people to take their information more seriously and make them understand what you're talking about, so it's easier to convince.
