The medical over-coital or post-coital fatigue caused by a group of fatigue syndrome is called post-coital fatigue syndrome. Usually continue to appear in a few minutes or hours after sexual intercourse, some patients complain that within a few days after sexual intercourse, they can not do anything, all day drowsiness, fatigue and weakness. The symptoms are: depression, listlessness, absent-mindedness, lax thinking, general weakness, shortness of breath and panic, weakness of the legs, eyes, dizziness, insomnia and dreaminess, loss of appetite, pale and haggard. The factors that lead to post-coital fatigue are divided into psychological, physiological and pathological. A, physiological fatigue traditional sex, men do the whole body movement, in the development of this movement to the climax, breathing faster, heart rate accelerated, blood pressure increased. The result will certainly accelerate the whole body consumption, inducing physical fatigue. Second, psychological fatigue Sexual life includes both physical exercise for men, including intense and complex mental activities. The energy consumption of the senior nerves, is bound to bring about psychological fatigue. Many men are more worried about the fatigue after sexual intercourse, excessive tension and anxiety, more likely to aggravate the fatigue of sexual life. This pathological psychology of people, over-exaggerated the negative role of fatigue, the normal appearance of physiological fatigue is very important, causing self-psychological torture, the emergence of this vicious circle. There is a fear of sexual activity, through abstinence to avoid sexual fatigue. And this psychological burden reflects the ignorance of sex. Third, pathological fatigue after sexual intercourse, certain underlying diseases: such as anemia, mild congenital heart disease, hypercalcemia, hypokalemia, low thyroid function and other symptoms appear. Some men in the week after sexual intercourse, all day dizziness, fatigue and weakness. For example: adrenal aldosterone tumor, chronic diarrhea, taking potassium diuretics, certain types of periodic paralysis, hyperthyroidism, hypothyroidism, diabetes hypoglycemia and other symptoms. In addition, some men may experience eye fatigue, eye swelling, blurred vision, and inflexible eye rotation after sex, which often lasts for several hours or even days. If the sexual life lead prosperous, then the above eye discomfort degree is more serious. There are pairs of cranial nerves from the brain that are located in the eye or orbit, which directly affect vision and eye movement. At the same time, the vascular pathway of vision is mainly supplied by the internal carotid artery and the posterior cerebral artery. When having sex, the energy and thinking are highly concentrated and the nerve activity is highly tense, so that the brain cells become temporarily fatigued, which affects the nerves that govern the eye activity and vision, and thus the eye fatigue occurs. During sexual intercourse, the vasoconstriction caused by high tension can also reduce the blood supply to the eyes and increase eye fatigue. At the same time, the subcutaneous tissue in the eyelid area is loose and fat-free, making it easy for blood and edema to form around the eyes, and for those who have sex too often to develop darkness or puffiness. When you have eye fatigue after sex, there is no need to be afraid, usually pay attention to more rest, arrange the frequency of sex, most of the eye fatigue can be relieved by itself. If still not relieved, you can do eye exercises, by massaging acupuncture points, eliminate tension, improve the blood circulation in the eyes, thus relieving eye muscle fatigue. Patients with post-coital headache often have a history of neurovascular headache, which is triggered by sexual intercourse. They are generally more common in men. According to the clinical manifestations of sexual intercourse headache is divided into the following three types: 1. Vascular headache: 70%. It appears before the action of sexual intercourse or during the peak of sexual desire, with a rapid speed and intense degree, confined to the forehead or posterior occipital region. It is explosive or throbbing and lasts for a few minutes to a few hours; later it turns into a mild dull pain and can last for about 48 hours. About 1/4 of patients have a family history of migraine with palpitations and occasional psychosis. 2.Tension headache: It accounts for about 25% of sexual intercourse headache. It occurs in the early stage of sexual intercourse and is heaviest during orgasm. It is manifested as a dull pain or tightness in the whole head or occipital area, which lasts for several hours to several days. 3.Low cranial pressure headache: accounting for about 5%. The headache occurs suddenly, and it will improve naturally after 2-3 weeks, and it can recur again after sexual intercourse. The headache is mostly located under the occipital bone and is obviously related to the body position. The headache increases in the upright position and is accompanied by nausea and vomiting. During sexual intercourse, due to sexual excitement, the muscles of the head and neck spasm, blood circulation is accelerated, blood pressure is increased, blood vessels become spasmodic and produce pain, and if there is a narrowing of the blood vessels, brain ischemia can also occur and cause pain. In addition, there are some life factors can also cause headache after sexual intercourse, such as sexual intercourse too often, too long, excessive physical fatigue, sexual intercourse environment is not good, the air is not smooth, noisy sound, can also lead to headache. Sexual fatigue is a natural phenomenon of the body. Sexual fatigue has an adaptation process.
