It's after three o'clock. Let's have some coffee first. Do sth. Do it? do it! Have some coffee first. No matter how much money you earn, you can't take it with you!

When it comes to sleepy, sleepy in spring, tired in summer, tired in autumn and hibernating, it is very familiar. But when will people not be sleepy? In the final analysis, I can still cook another episode and play another game when I face my cell phone at night, and I want to ask for leave as soon as I open my eyes during the day.

How can today's workers throw in the towel so easily? What can't be solved by a cup of coffee? Yes, that's two!

It is hot and time-consuming to go downstairs to find a cafe, and it is expensive to order takeout. Hanging-ear coffee? It's not as fast as freeze-dried coffee and cold extract coffee. When people with choice difficulties finally figure out what they want to drink, the question comes again: do I drink so much coffee that I can't sleep at night? How much can I drink at most a day?

Nowadays, everyone knows that drinking coffee is refreshing because there is caffeine in it. After caffeine intake, it reaches a peak in 30 to 60 minutes. When your body metabolizes half of the caffeine, it usually takes three to five hours, and the rest of the caffeine will stay in your body for longer. Because caffeine is metabolized by the liver, a person with a bad liver can metabolize caffeine more slowly, and the unit can even change from hour to day.

So, why do people feel tired? That's because there are adenosine and adenosine receptors in the brain. With the binding of adenosine and adenosine receptors, signals of fatigue are transmitted to the brain, and after receiving such signals, people feel tired.

Seeing this, you should understand how caffeine helps to refresh the workers. That is, caffeine acts as a mistress in this relationship, intervening in the relationship between adenosine and adenosine receptors. When caffeine enters the body, the mistress kicks adenosine away, dominating the adenosine receptor. When the receptor leads the original ration to the brain, it gives the order to rest, while when the receptor, the scum man, leads the mistress of caffeine to the brain, he gives the instruction to continue to work.

Caffeine binds to adenosine receptors and the discharge of neurons in the brain increases. When the pituitary gland suddenly finds that something is wrong, it will stimulate the adrenal gland to work and produce adrenaline, thereby reducing fatigue.

When you first start drinking coffee, you may feel awake and afraid that you can't sleep at night. But as you drink coffee regularly every day, you begin to develop a tolerance for caffeine. When adenosine receptors are occupied by caffeine for a long time, more adenosine receptors are produced in your body. only in this way can adenosine bind to the extra adenosine receptors to send signals that need to rest.

Therefore, when a worker who has a habit of drinking coffee wants to be refreshed, the usual amount is not enough for him. Does that mean that the worker is immune to caffeine and has no problem with how much he drinks?

Of course not. A group called FDA points out that daily caffeine intake of 400mg is OK for a healthy adult. However, this is not the case, because each person's metabolism rate is different, each person's intake is also different. When you find yourself getting anxious, rapid heart rate, gastrointestinal discomfort, headaches and nausea, you are eating too much caffeine into your body.

There is also no shortage of deaths from caffeine overconsumption around the world, such as 19-year-olds who died after taking the equivalent of 4800 milligrams of caffeine.

So, how much caffeine does the latte in your hand contain? It's actually the caffeine content of an espresso. According to a rough reference value provided in the table below, it is possible to drink three or four cups of coffee a day.

This tabular data is estimated based on the USDA National Nutrition Standards Database and information provided by manufacturers and does not specify a particular coffee bean variety or coffee brand.

Since the powder content and extraction rate of each cup of coffee are different, the caffeine content of each cup of coffee may not be the same. The specific calculation formula is as follows:

Weight of coffee powder used * extraction rate * caffeine content of coffee beans (Arabica caffeine content is about 1.2%)

All in all, living on caffeine seems to be a way to overdraw the body, so it's important to go to bed early and get up early to save your life. And coffee this thing, usually drink one or two small cups, like wine tasting is also very good.

It's time to take a break. It's time for coffee. Drink after drinking, don't drink too much.
