Is coffee the honey or arsenic of your spirit?

The temperature in July will soon soar above 38 ℃!

It seems that "unintentional work" is a serious thing.

Especially in Blue Monday every week, the symptoms are more obvious.

Whenever drowsiness strikes

Suifa Jun said that drinking five cups of coffee didn't work!

Isn't it refreshing to drink coffee?

Is it all a lie?

Q

Why is it that some people drink coffee like chicken blood, while others have no effect?

We all know that drinking coffee is because of caffeine. But why is caffeine refreshing?

When our bodies are tired, they produce a substance called adenosine.

And the caffeine in coffee is very similar to this substance. When caffeine enters the brain, it prevents adenosine from binding to the receptor. In other words, when caffeine takes up the position of adenosine, adenosine does not play its tiring role. I can only tell you that they are "snatching the throne"! Caffeine wins! Win, can make you excited!

However, if we drink coffee when we are already tired, it will be too late. Because adenosine is in place!

Mr. Sleeping, got it! Every time I feel sleepy, I go to buy a cup of coffee! At that time, it was as if the decree had been issued, and you were powerless to resist! So in the future, if you think you have a lot to do today, you must drink in advance.

Q

So, as long as you drink caffeinated drinks in advance? So you can avoid being sleepy?

To put it simply, caffeine kicked out adenosine and ascended the throne! So the cells have no way to sense adenosine. Originally, the body was already very tired, constantly uploading signals to the brain and applying for rest, but as a result, the brain could not receive the signal that it needed to rest, so it had to work hard all the time.

Of course, it should be noted that caffeine can block drowsiness, excite spirit and boost energy in a short time, not that caffeine eliminates fatigue. It just deceives the brain and prevents the brain from receiving the signal that it needs to rest for the time being. This leads to when it is time to go to bed, due to the intake of caffeine, the human body will not produce drowsiness and continue to be alive!

Q

Then drink as much coffee as you can, 10 cups a day? Will you work efficiently?

In fact, as mentioned above, this is an illusion for your brain! If you come out to hang out, you will have to pay it back sooner or later! Should I sleep or should I sleep? You have been drinking coffee efficiently for 8 hours, only for a short time, and you may be more sleepy the next day! And for most healthy adults, caffeine less than 400 mg a day is safe, excessive caffeine intake will have varying degrees of negative effects, such as rapid heartbeat, gastrointestinal disorders, muscle tremors and so on. Oh, my God, it may be a sudden death again!

Q

So don't drink coffee for the sake of health?

You can't say that! If you are a coffee lover, drinking a little coffee is good for your body and mind. Can reduce the probability of suffering from a series of diseases!

Sleeping law Jun wants to say: enjoy the natural taste and abandon the extra addition. Drinking up to one cup of coffee a day is the healthiest, and choose no sugar or cream as much as possible.

Say how to sleep

01

Caffeine can effectively alleviate attention deficit caused by sleep deprivation, which is helpful for simple repetitive cognitive activities (such as driving); caffeine does little to alleviate the effects of sleep deprivation in advanced cognitive processes and executive functions.

02

Caffeine does not help with other adverse effects of lack of sleep, such as an increase in stress hormones, which increases the likelihood of anxiety and depression.

03

Caffeine is potentially addictive, and once abstinent, it will cause anxiety, insomnia and other reactions. Similarly, caffeine can also be resistant, and long-term use will reduce the effect. This is why the more you drink, the more ineffective it is.

If you're not a coffee lover,

To sum up,

If there's a choice.

Getting up after sleep is far better than staying up all night drinking coffee.

In the final analysis, this "throne" is snatched, the name is not correct!

The most orthodox way is: sleep well!

Finally, those who are addicted to coffee more than four or five cups a day

Are you all right?
