1. The harm of excessive sexual intercourse

(1) consumes kidney qi, leading to infertility and premature aging. Traditional Chinese medicine believes that kidney qi is the pre-pressure of biological activities. If kidney qi collapses, semen quality will deteriorate and infertility will occur. Therefore, in the stage of seeking fertility after marriage, it is necessary to host interest-bearing, especially for infertile patients with abnormal semen. Middle age is the turning point of kidney qi from prosperity to decline. With the decline of kidney qi, the body is gradually aging, and more attention should be paid to the maintenance of essence.

(2) weaken the self-defense force, leading to the emergence of diseases. The healthy qi of human body is a self-defense force against the invasion of evil spirits and successful diseases. But the kidney essence is weak, the vital qi is weak, and the defense force is contemptible. Wind, cold, heat, humidity, dryness and fire will all invade the human body and cause diseases. Therefore, in the stage of abnormal climate and epidemic diseases, we should avoid sexual intercourse, live a healthy life, and guard against diseases and evil humiliation. In the process of illness, we should master the resistance of healthy life to promote early recovery.

(3) The development of coherence leads to inefficiency. Fornication, mental deficiency, brain deafness, dizziness and tinnitus, easy to forget; Bone malnutrition leads to waist pain and knee weakness. All this will be related to the development of Minhui's talent and physical strength, leading to a decline in work efficiency. Therefore, whether it is mental work or manual work, in the stage of hasty work and fierce competition, we should avoid sexual life as much as possible, live with enough energy and develop great potential.

2. The harm of excessive exercise to human body.

Excessive exercise makes the blood supply and oxygen supply of human organs unbalanced, leading to premature aging of the brain, disrupting the endocrine system, destroying the immune mechanism and accelerating the wear and aging of the body.

Effect of (1) on cardiovascular function

Excessive exercise can cause sustained injury of myocardial capillaries, impatient cell hypoxia injury, serious damage of myocardial contraction and relaxation performance, and decrease of myocardial mechanical indexes, which are manifested as chest tightness, arrhythmia, accelerated resting heart rate and slow recovery of heart rate after exercise. Excessive exercise can obviously enhance the platelet aggregation ability, that is, the peripheral circulation function is abnormal, leading to tissue ischemia and hypoxia, which may lead to the decline of collective exercise ability and anti-fatigue ability. Excessive exercise sometimes leads to a sudden drop in effective blood volume and blood pressure, causing exercise shock.

(2) Effects on nervous system

Excessive exercise can lead to memory loss, dizziness, headache and insomnia. Symptoms such as pallor, nausea, sweating, dizziness and tinnitus may also occur, which may even lead to loss of consciousness and muscle tension and sudden syncope.

(3) Effect on skeletal muscle function

Excessive exercise can cause skeletal muscle contraction function decline, material metabolism change and even muscle ultrastructure damage, muscle intracellular calcium level disorder, calcium ion concentration increase, muscle pain. Excessive exercise can also cause tendon injury.

(4) Effect on gastrointestinal function

It can lead to loss of appetite, nausea and gastrointestinal dysfunction.

(5) Influence on urinary system

Can lead to collective sweating, renal blood flow reduction, urine concentration, resulting in hypertonic protourine. During excessive exercise, vasoconstriction is the lack of oxygen and carbon dioxide storage, which leads to acute kidney injury and increased membrane permeability, which may lead to exercise hematuria.

(6) Influence on immune function

Promote the release of immunosuppressive hormones in the body, which shows that the immune function of the body is suppressed, thus affecting health. During strenuous exercise, the contents of adrenaline and cortisol increase. When it exceeds a certain level, the ability of spleen to produce white blood cells decreases, which weakens the activities of lymphocytes and natural killer cells. Excessive exercise reduces immune function, increases the body's susceptibility to upper respiratory tract infection and other viral infections, makes the whole body weak, loses weight, and is prone to colds, pneumonia and gastrointestinal infections, providing pathogenic conditions for immune diseases such as anemia, rheumatoid arthritis and diabetes.

(7) It is prone to sports injuries.

People who have just started to take part in physical exercise sometimes cause fatigue fractures at the attachment points of bones and muscles after continuous excessive exercise. Excessive exercise leads to chronic joint strain, which is manifested as joint pain and swelling. It can also cause the heel pain mentioned above.

(8) Effect on antioxidant capacity

Long-term excessive exercise is the decline of antioxidant capacity, the increase of free radicals produced by the body, and the acceleration of aging.

3. The health benefits of proper sexual intercourse:

Healthy sex is the sweet spring that nourishes marriage and sexual relations. According to the latest report of an American doctor of network medicine, medical experts have summarized 56 reasons for supporting sexual behavior from the medical, physiological and psychological perspectives through long-term scientific research and clinical investigation. This paper extracts some contents from it, hoping to draw lessons from readers.

A study by Queen's University in Belfast, England, shows that men who have sex three or four times a week will have a half chance of heart disease and a half risk of stroke.

30 minutes of sex is equivalent to consuming about 200 calories, which means you can eat an extra chocolate.

Harmonious sexual life can promote the brain to produce more neurotransmitters, which is helpful to relieve mood and depression.

Moderate massage after sex helps to secrete endorphin, a sleep inducement, which makes people sleep more soundly.

Regular sexual life can promote the brain olfactory bulb to produce new nerve cells and improve the sense of smell.

Prevent tooth decay. Male semen is rich in zinc and calcium, which can reduce the probability of tooth erosion.

Endocrinologists from Columbia and Stanford University have found that women have sex at least once a week, which can make their menstrual cycle more regular.

The boundary between pain and happiness is very thin, and sex can help people distinguish the difference between them and feel happiness more strongly.

Sex can speed up childbirth. Male semen is rich in prostaglandin, which can naturally expand after entering the female cervix, leading to a smooth delivery.

Improve communication skills. Taking the initiative to express your thoughts in sexual life is helpful to express your views well in other fields.

Sex gives people more happiness than wealth. According to a recent survey published by the National Bureau of Economic Research, if measured by data, the happiness generated by a harmonious sex life is equivalent to the happiness brought by earning $6,543,800 a year.
