Coffee is a good medicine for many young jobs, but for the matter of drinking coffee, Li Chunyan, a doctor of digestive medicine in Chongqing West District Hospital, reminded not to drink too much or drink too much.Because of too much coffee to drink too much in the emergency room.
Not long ago, a hospital had admitted such cases.It is understood that after drinking 8 cups of coffee on an empty stomach, the patient was stiff and unable to move on the high -speed road, and accompanied by symptoms such as acceleration of heart rate and acceleration of heartbeat, and life danger occurred.Fortunately, it was found that the traffic police were helped in the first time, and they were sent to the hospital in time to turn the insurance.
So, what is the principle of coffee refreshing?How to drink it correct?Who is not suitable for drinking?
The working principle of caffeine in the brain
According to Li Chunyan, the role of caffeine is actually blocking the reception of fatigue signal substances.When people are tired, they will tell the brain through a signal substance called adenohide, letting the brain know "I am tired", and the more tired adenosine the substances.The role of caffeine is to bind to the adenosine receptor to block the transmission information, which is equivalent to preventing the normal combination of adenosine and receptor, so that the brain cannot receive signals passed by fatigue substances, and it will not feel tired.
Why is sometimes sleepy but not used?
Sometimes caffeine can help refresh, but sometimes there is no effect at all. Why?To sum up, there are several reasons:
Drinking late: When adenosine and receptor have been combined, the caffeine is not meaningful at this time to prevent them from stopping them.
Drink too much: Drinking coffee often produces antibodies, which resists the role of caffeine.Just like drinking alcohol often can resist alcohol, often taking a medicine will produce drug resistance.
Fast metabolism: Some people have a strong metabolic function, and even more coffee will quickly discharge from the body. For such people, drinking coffee is just equivalent to "quenching thirst".
When is it the best time to drink?

Half an hour after eating, this time is the best time to drink coffee in the day.Therefore, drinking coffee at this time can promote the digestion of food in the stomach and reduce the burden on the stomach.
Drink coffee before exercise

Generally speaking, drinking a cup of coffee can play a 4 -hour refreshment.Therefore, it is best not to drink coffee in the evening to avoid affecting sleep.
Wine and coffee should not drink at the same time
After drinking alcohol, alcohol will be absorbed by the digestive system quickly, and then enter the blood circulation system, which can directly damage myocardial cells, affect the energy metabolism of myocardial cells, weaken myocardial function, increase the burden on the heart, and cause coronary blood supply disorders, which is prone to arrhythmia.Nothing.
If you drink coffee after drinking, the brain will turn the brain from extreme suppression to extreme excitement, stimulate vascular dilation, accelerate blood circulation, increase the burden on the cardiovascular, and even induce high blood pressure. If you add emotional excitement, tension, dangerousness, dangerousnessIt will be bigger.Therefore, drinking coffee after drinking is a higher chance to induce myocardial infarction.
