The body's blood vessels to the domination of the two, called a 
sympathectomy, when excited to vascular expansion and another called Vice 
sympathetic, to be excited when the blood vessels to contract, so that when 
the inhibition of vascular expansion. Normally, the two co-ordinated control 
of the vessel contraction and expansion. Alcohol can sympathetic excitement, 
and restrain the Deputy sympathetic to greatly expand blood vessels than 
usual. Facial skin thin, capillary another, so people will face after 
drinking red.
      Why do some people will be drinking blush, and some people will face 
Fabai ? Let us start with the reasons for the blush from it. Many people 
think that alcohol is the result, the contrary, is caused by acetaldehyde. 
Let telangiectasia acetaldehyde with the function and facial capillaries is 
the expansion of the reasons for the blush. Therefore, drinking blush means 
that people can quickly be transformed into ethanol acetaldehyde, which 
means that they have efficient alcohol dehydrogenase (alcohol 
dehydrogenase). But we can not forget that there are an enzyme, aldehyde 
dehydrogenase (aldehyde dehydrogenase). Drinking blush of the people of not 
only the first one after an enzyme, in rapid accumulation of acetaldehyde 
and delays in metabolism, so long up Hong Lelian. But everyone has 
experience, when one or two hours after the legs will gradually to red, 
which is on the liver, the P450 will be gradually transformed into 
acetaldehyde into acetic acid and then into the TCA cycle was metabolism.

So alcohol is relatively powerful people how going on ? These people often 
face more drink more white, to a point can not suddenly, drunk Runi. That is 
because such a person of high activity of alcohol dehydrogenase and aldehyde 
dehydrogenase are not mainly rely on the liver, slowly of P450 (P450 is 
because of the relatively low specificity of a group of oxidase). So, why 
such a person is able to give people the feeling of alcohol? ? At that time, 
because they rely on body fluids to dilute alcohol, the greater the feeling 
of the head to drink. Under normal circumstances, the alcohol concentration 
more than 0.1% of them will be in coma, the majority of southerners are 
Banjin liquor, but the northerners due to size, where you can drink 8 to 
Yijin two liquor. But no matter who, if he is the face of the White Yuehe 
Yue, preferably not more than Banjin, or have the possibility of acute 
alcoholism.
If a person is a high activity of another high-alcohol dehydrogenase 
activity of aldehyde dehydrogenase what would be ? He / she is the legendary 
wine baskets. How to judge him / her is not wine baskets? ? Do not sweat a 
lot. If the two are of high activity, alcohol quickly become acid into the 
TCA cycle fever, fever and sweating a lot. Encountered this kind of person 
you can only Zirendaomei that eight of 10 normal He also Doubu Guo. 
Fortunately, so not many people, probably about one in 10 bar.

It is to remind everyone that drinking blush of liver injury in fact not 
easy, and the wine and white faces are particularly vulnerable to liver 
injury. Members of the general red Quanjiu less, drinking less, drink Fakun, 
sleeping on another 15-30 minutes on the Jingshendousou. Bailian and the 
often do not know their own ground, in a highly excited in the excessive 
drinking until drunk. Their bodies of alcohol in the absence of high 
activity in the treatment of accumulation, leading to liver damage. 
Alcoholic liver injury generally occurs only in those people. The red for 
several meals may even have to drink a drink vomit, and Bailian people need 
more time to rest, because alcohol metabolism needs 12 days time.
Incidentally, according to the study of Jiangsu and Zhejiang Provinces 
(ancient Wu and the descendants of the country) seems to be the origin of 
the red gene, meaning that most of these people with high activity of the 
alcohol dehydrogenase. The northerners are the majority of white facial. So 
if you are born in the north, but also a red-and explain what it ? The 
answer is obvious, because the red gene is dominant gene. Many people drink 
red face, this is the role of alcohol in the outcome of the central nervous 
system.

After drinking alcohol in the stomach will be resolved absorb part of the 
liver can also filter part of metabolism. Excessive drinking, over the 
stomach and liver to resolve the metabolism, the remaining blood into the 
brain as alcohol, the normal function of brain cells has changed and thereby 
facilitate the expansion of facial skin blood vessels, increase output, will 
face reddening. If you look at the redness has continued to drink, will 
speed up the heart, blood vessels expand, blood pressure dropped, in order 
to ensure that the main organ in the blood supply, we must shrink capillary 
blood pressure to rise. Therefore, the facial peripheral vascular disruption 
in the flow, blood volume reduction, on a green face.

Regular alcohol, vascular constant expansion and contraction, a long time, 
the vessel will become very fragile and capillaries on the face may rupture, 
causing a red skin on the point. For example, Jiuzao Bi is the long-term 
expansion by the local blood vessels caused by a chronic skin diseases, with 
10% of alcohol has a lot.
      Left of alcohol in the blood lead to brain function changes, but will 
also affect the body's muscle activity. Therefore, Yaoyaohuanghuang drunk to 
walk, speak vague.
      If the flight sprinkling drink alcohol on the body's impact will be 
greater, because then things can not stomach dilute the alcohol, resulting 
in more alcohol from the blood flow to the brain.
      The role of alcohol will also increase the secretion of adrenaline, 
adrenaline will center vasoconstriction, or hypertension is the role, so 
alcohol will be induced hypertension.
