Sleepy in spring and napping in summer, many people at work usually like to drink a cup of coffee to refresh their minds, so have you ever thought about how drinking this cup of coffee will affect you? Is coffee good for you? Does it really improve work efficiency?

When judging coffee, you must consider the following things.

1. Coffee can improve brain performance and agility.

Medical editor Stephen Braun has pointed out that caffeine inhibits adenosine receptors, a compound in the brain that produces drowsiness. This explains why many people feel less tired when we drink coffee.

At low doses, caffeine is also said to improve brain performance and agility. It should be pointed out that caffeine has different effects on all people. Your personal reaction to caffeine may be very different from that of others you know.

Other factors that affect your response to caffeine include intake, weight, age and even sleep quality. You should also know that over time you may build up immunity to caffeine, which means that a cup of coffee may no longer motivate you as much as it used to.

In fact, some people have no feeling when they drink a cup of coffee, but this is nothing to boast about. This only means that you are already addicted to caffeine.

In addition, in the short term, caffeine can improve your cognitive ability, memory and agility, and even inject energy into you. But as we know, the effect is short-lived, and you are likely to collapse later.

Coffee will affect the quality of your sleep.

With less caffeine, caffeine will not affect your schedule. But if you eat too much, you'll probably find it hard to sleep at night. This is likely to lead to a vicious circle of sleep deprivation, stress and poor job performance. The long-term result may be overwork or even mental weakness.

In addition, excessive consumption of caffeine can cause stomachache, extreme nervous tension and even palpitations.

Now everyone is more concerned about sleep, it all comes down to the clash of ideas between the compact way of thinking advocated by entrepreneurs such as Gary Venecchak and Grant Cardoni and the diametrically opposed views put forward by James Altuchell and Arianne Huffington.

Only you know what's best for you, but in any case, it doesn't hurt to know that your sleep will be affected by caffeine. Therefore, it is important to understand that moderate consumption of caffeine is the best choice.

Coffee may strengthen your willpower.

So far, it has been agreed that people's willpower will be exhausted by making decisions in the course of the day. This may be one of the reasons why Steve Jobs wears the same clothes every day. He doesn't have to think about what he wants to wear when he gets up in the morning, so he is able to reserve willpower for big decisions.

Coffee has been shown to boost your willpower and self-control, especially when you feel exhausted. It is unwise to make a big decision when you are tired. In the end, you may give in to your own point of view, succumb to pressure in negotiations, or start a new project at an inappropriate time.

However, drinking coffee in advance may help you strengthen your position and make more reasonable decisions. Keep this in mind when you have to make a big decision after a busy day.

4. Drinking coffee at the wrong time can lead to elevated blood pressure and adrenaline.

Entrepreneurs are always facing new challenges and solving problems all the time. In business activities, a strong spirit is essential. But even the best people can become exhausted and stressed. If it is not solved for a long time, you may even have a complete breakdown.

Then you are likely to become more and more dependent on coffee when you are exhausted. It turns out that this is the worst time to drink coffee, as it is likely to lead to a rise in blood pressure and an increase in adrenaline. As we already know, caffeine suppresses adenosine, so when you drink a cup of coffee in a hurry, the gradual process suddenly happens overnight, making you feel even more tired.

Coffee sounds a little innocent, but it does cause panic attacks. Once this happens, it often takes a long time to deal with anxiety. You may end up with an anxiety disorder. Although having a cup of coffee is generally helpful when you are under extreme stress, you don't need to consume too much caffeine when you are under great stress.

Coffee can make you learn faster.

Many entrepreneurs are good at extracting useful information, whether it's articles, blog tweets, magazines, industry journals, books, podcasts or videos. This information helps them make decisions and enables them to generate and implement new ideas in their business activities.

Current research suggests that attention, like willpower, decreases slowly over the course of the day. There is evidence that 200 milligrams of caffeine can help you read words and paragraphs faster than no caffeine.

Many entrepreneurs make it their goal to learn new skills or learn more about their company's position in the industry. Maybe you need one or two cups of coffee to motivate yourself to focus all your attention on the material you are learning and apply it to your company.

[summary]

In theory, caffeine does have a refreshing effect. When people don't have a rest for a long time, they naturally feel tired and tired. When the body is tired, it tells the brain through a signaling substance called adenosine. And the more tired the body, the more this substance.

But for the brain to know, "I'm tired," you have to dock the substance with a particular receptor in the brain. The caffeine in coffee can also bind to this receptor-and block the messenger, which is equivalent to blocking the normal binding of other receptors. In this way, the brain will not be able to receive signals from fatigue materials, and it will not feel tired, and it can carry 4Murray for six hours to have a "refreshing" effect. However, the amount of adenosine that makes people feel tired has not decreased. Therefore, caffeine refreshing is short-lived, the body should have a proper rest when you are tired.
