Loss of yang

　　The loss of yang is a concept from traditional Chinese medicine, which actually refers to a state where the body is in a condition of yang deficiency, characterized by excessive sweating, cold hands and feet, palpitations, shortness of breath, dizziness, and even coma, with a thin and rapid pulse, similar to a shock state in modern medicine. Some literary works use this to describe the state after excessive sexual activity, which is also a shock state. However, it is not common for most people to experience it, and it does not mean that frequent sexual activity will lead to it. It may occur in some people with diseases (mainly cardiovascular diseases) during excessive sexual excitement.

　　The loss of yang often leads to sudden death. Modern medicine believes that during sexual activity, the human nervous and endocrine system is highly excited, often accompanied by holding breath, which adds a dreamlike sexual pleasure, but in fact it is a brain oxygen deficiency. People with pre-existing heart and brain diseases, if sexual excitement exceeds the physiological limit and lasts too long, the brain oxygen deficiency becomes severe, the autonomic nervous system is out of control, which can cause respiratory depression, sudden cardiac arrest, and loss of consciousness. Usually, it starts with sudden dizziness, chest tightness, and pale complexion, followed by unconsciousness.

　　The main measures for preventing the loss of yang are as follows:

　　1. Eliminate extramarital affairs and strengthen moral cultivation.

　　2. Have moderate sexual activity. Have sexual activity based on the ages and energy levels of both partners, avoiding frequent occurrences, intense movements, or prolonged duration. Gentle actions such as embracing and caressing before and after sex can also produce or enhance sexual pleasure and prolong excitement.

　　3. Avoid sexual activity during fatigue. After sexual activity, rest on the bed for a period of time, do not rush to eat, take a bath, or engage in other activities.

　　4. Adhere to the ancient saying 'Do not enter the room after drinking.' It is also not advisable to have sex immediately after eating a lot, drinking coffee, or smoking a lot.

　　5. If you feel chest tightness, nausea, vomiting, or dizziness during sexual activity, stop immediately. Patients with coronary heart disease can take a small amount of nitroglycerin or nifedipine before sexual activity as a preventive measure. If heart or breathing stops, the spouse should not panic and can immediately perform mouth-to-mouth resuscitation and external cardiac massage for emergency rescue, while calling the emergency number at the same time.

　　Since deficiency of Yang is a sudden loss of consciousness, modern medicine believes it is related to central nervous system lesions, so the following examinations should be performed:

　　1. Cerebrospinal Fluid Examination: To differentiate central nervous system infections based on the protein, chloride, and glucose content of cerebrospinal fluid. If there are red blood cells in the cerebrospinal fluid, it indicates intracranial hemorrhage.

　　2. Head CT Examination: To determine whether there are hemorrhagic, space-occupying diseases, or vascular malformations and ruptures that cause sudden loss of consciousness.

　　3. Brain Ultrasound Examination: To determine whether there are space-occupying or hemorrhagic diseases in the intracranial cavity, usually in conjunction with head CT scans.

　　4. EEG: To determine whether there are abnormalities in brain function, such as sudden seizures.

　　Other routine checks should include blood routine, blood pressure, blood glucose, ECG, electrolytes, and blood gas analysis to determine whether there are signs of acid-base imbalance and cardiac insufficiency.

　　To prevent and treat deficiency of Yang, it is recommended to eat more foods that are easy to 'activate' (sweet, warm, and invigorating) in daily life, such as beef, mutton, dog meat, scallions, ginger, garlic, Sichuan pepper, eels, chives, chili, and pepper; and to eat less cold and cool foods, such as cucumbers, lotus roots, pears, and watermelons.

　　The traditional Chinese medicine name for 'deficiency of Yang' is a disease where seminal fluid continues to flow during sexual intercourse, resulting in immediate death. Western medicine considers this disease to be cardiac paralysis, often resulting in insufficient emergency treatment and death during transportation to the hospital. When traditional Chinese medicine encounters this disease, it uses独参汤 for emergency treatment, which is a decoction made from a large amount of ginseng. However, it may not be timely to boil the decoction. As an emergency measure, 5 cm of ginseng powder and 2 cm of附子 powder are taken with warm water, which also has the potential to save a life.
