Is the red one good? Why is the face red?

A slogan says: rosy face is charming! Red face is usually used to describe a person's good complexion and good health, but red face is not always a good thing, and sometimes it hides the crisis of certain diseases. Luo Hongyu, an attending physician in the Department of Acupuncture and Moxibustion of Guangxi People's Hospital, believes that everyone has different constitutions and some people are prone to blush. People who have always been prone to blush are often blushing from the inside out, red and yellow, which is a sign of sufficient blood. People often praise these people for blushing, which is a sign of health. Explained from western medicine, Xie, director of dermatology department of the 303rd Hospital of the People's Liberation Army, believes that some people have good peripheral blood circulation, and their faces are rosy after a little activity, which is also a healthy performance. Some people live on the plateau, and their bodies need more red blood cells to carry oxygen, which is normal. In addition, some people will blush because of shyness, anxiety, anger and nervousness, which are all psychological blushes caused by emotional changes. Are people who don't blush easily healthier than those who blush easily? Luo Hongyu said that this cannot be generalized. Everyone's physique is different. Those who don't blush easily even after exercise and when they are nervous are very healthy as long as they don't turn blue. Taking medicine can also cause blushing. Song Jiansheng, pharmacist of Guangxi Youhe Ancient City Pharmacy, said that taking nifedipine, nitrendipine and other drugs may dilate blood vessels, lower blood pressure, and dilate facial capillaries, causing some blushing, which is a normal reaction and has little impact on health. Zhou Haifeng, director of Guangxi Traditional Chinese Medicine Association and deputy secretary-general of Guangxi Sub-health Science and Technology Research Association, said that there are many reasons for blushing, such as stimulating sympathetic nerve to cause cervical vertebra displacement and facial vasodilation. Afternoon hot flashes caused by yin deficiency; Living in areas with strong ultraviolet rays, plateau red will also appear. No matter what causes the blush, if people who are not easy to blush suddenly blush, it may be a problem with their physical function, so be alert. Blushing reminds you not to drink. Blushing is a sign of not drinking. People who blush after drinking, whether drunk or not, should not continue to drink. Why? Li Nanzhong, director of the Endocrinology Department of the 303rd Hospital of the People's Liberation Army, said that many Asians turn red after drinking alcohol, because acetaldehyde produced by alcohol metabolism accumulates in the body. Alcohol is decomposed into various substances by various enzymes in the human body. If an enzyme is deficient or insufficient, it is easy to decompose and produce acetaldehyde. If acetaldehyde accumulates in large quantities, it is easy to blush. Moreover, acetaldehyde is harmful to the body, so blushing after drinking is to remind you not to drink any more, otherwise it will cause more acetaldehyde to accumulate in the body and cause greater harm. Some menopausal middle-aged women may find that they often blush involuntarily when they are in their forties, and they can't find out why. Bai Hua, director of gynecology department of Guangxi Maternal and Child Health Hospital, reminded that middle-aged women are blushing, which may be menopause. Bai Hua said that menopausal blushing is often accompanied by paroxysmal flushing and hot flashes for a period of time, and suddenly feels fever in the chest, neck and face, sometimes accompanied by symptoms such as headache, dizziness and fatigue. Sometimes it gets worse at night, even affecting sleep and work during the day. At this time, women may also have blood pressure fluctuations, mainly systolic blood pressure (high pressure), which can return to normal after a few hours. This phenomenon is most obvious in premenopausal 1~2 years, and the symptoms gradually decrease or disappear after one year. Middle-aged women with this condition may wish to see a doctor, supplement estrogen under the guidance of a doctor or take other treatment measures to alleviate it. Watch out for high blood pressure. People with high blood pressure will also blush abnormally. Why? Huang, director of the Second Department of Neurology, the First Affiliated Hospital of Guangxi College of Traditional Chinese Medicine, said that patients with hypertension will have dilated and congested blood vessels in the head and face due to heart enlargement, myocardial hypertrophy and enhanced myocardial contractility, which will lead to redness. Therefore, some patients with hypertension often blush. In addition, Luo Hongyu also believes that if a person's cheekbones suddenly appear dark red, it may be a harbinger of heart disease; If the facial red pulse has no roots, it may be caused by hypertension; May be weak, liver yang hyperactivity. Luo Hongyu introduced that if some people have bright red faces, accompanied by dry mouth, sweating and athlete's foot, it is a manifestation of yin deficiency; Some people are pale red, but their hands and feet are prone to chills, and often have symptoms such as chest tightness, backache and floating pulse, which are caused by yang deficiency. If the elderly appear blushing, it may be caused by hyperactivity of liver yang in traditional Chinese medicine, mainly manifested as sudden blushing at noon; For people with hyperactivity of liver yang, you can eat some Zhengan Xifeng decoction and Qianyang Dan appropriately; For people with lung yin deficiency or kidney yin deficiency, you can take some Liuwei Dihuang pills appropriately; For menopausal women, you can properly eat some Xiaoyao San, Lily Dihuang Decoction and Shengmai Drink to regulate qi and blood. Blushing is determined by the human brain. When encountering special stimulation, people transmit stimulation signals to the cerebral cortex through sensory organs such as eyes and ears, and an important role of the cerebral cortex is to stimulate the adrenal gland, which will secrete adrenaline when stimulated. Adrenaline is a catecholamine substance, which is converted from tyrosine in the body. Its functional characteristics are that it can dilate blood vessels, especially small subcutaneous blood vessels in the face; But when adrenaline is secreted in large quantities, it will cause blood vessels to contract. When external stimuli such as shyness are introduced into the brain, a small amount of adrenaline will be secreted, which will dilate facial blood vessels and increase blood flow. The color of blood is red, so it is easy to cause psychological blush. When people's mood changes very seriously, they will secrete too much adrenaline. At this time, their faces are not red, but they will cause temporary anemia because of the decrease of blood flow caused by vasoconstriction, so we see that some people's faces are white when they are very angry.
