Neijing said: "A woman is seven years old, with full kidney qi and longer teeth." "Tooth", except the tooth bone, is the expression of the north kidney and represents the collection. "Hair" is hair, which is the expression of liver qi and represents the opportunity for hair growth. So the length of hair is related to vitality. "On the 27 th, the sky is coming, the pulse is connected, the pulse is too strong, and the month is in the present, so there is a son." Erqi is a woman who began to have menstruation at the age of fourteen and her breasts began to develop. At this time, she has the ability to get pregnant and have children. By the time she was 372 1 year old, the woman's kidney qi had reached its peak and she should get married. By the age of 47 or 28, all the elements of a woman's body have reached a peak, so the ancients advocated that a woman should get married around the age of 20, that is, let her have children before the age of 28. Now we often say that the best childbearing age is between 23 and 28 years old, which is the reason. "On May 7, Yangming's pulse failed, his face began to burn, and his hair began to fall." Women begin to get wrinkles at the age of 35. By the time I was 6742, I began to have white hair. Amenorrhea and loss of reproductive function. From this we can see that women have been aging since the age of 35.
As for a man, his life rhythm is based on the cycle of eight years old, starting from the age of eight and entering adolescence at the age of sixteen, "being able to have children". At the age of 3824, it is the age when men are weak, that is, they have just reached adulthood. At this time, their bodies are still weak and not suitable for marriage and sex life. The most suitable age for a man to get married is 4832 years old. At this age, his body reaches a peak, and he really matures. Therefore, the ancients advocated men to get married at the age of 30. The life rhythm of 4832 has passed, that is, 5840 years old. At this time, a person's body began to decline, he began to really get old at the age of 6848, and really entered old age at the age of 8864.
German researchers recently found that women's skin ages faster than men's. Experts from many institutions in Germany jointly conducted this research. They used "multiphoton laser imaging" technology to illuminate the inside of the forearm of 18 volunteers. These volunteers included 7 women and 1 1 men, aged between 2 1-84 years. Under the irradiation of infrared laser pulse, collagen in skin emits blue light and elastin emits green light. Based on this, the researchers measured the relative contents of these two protein in the skin of volunteers. Results They found that in the same age group, the loss rate of collagen in women's skin was faster than that of men, and the physical appearance of the network structure formed by collagen in men's skin was younger. Collagen and elastin are two kinds of protein in skin, and the growth, repair, nutrition, elasticity and tension of skin are closely related to them. Among them, the role of collagen is more important. 75% of dermis is composed of collagen, which undertakes two key missions: anti-wrinkle and moisturizing. The human body can produce a lot of collagen when it is young, but with the increase of age, their output will decrease. Researchers believe that women's skin ages faster than men's because they need to consume more collagen than men. After menstruation, the endometrium falls off and the damaged uterus needs to be repaired. The endometrium is composed of collagen fibers and needs a lot of collagen. In addition, childbirth and induced abortion can also damage the uterus, which in turn requires the consumption of collagen.
In fact, the explanation of traditional Chinese medicine coincides with the research in Germany. In life, people feel that women are getting older faster than men. Once a woman is over 30 years old, she begins to lose her shape and her skin begins to age ... Experts believe that this is because menstruation, pregnancy and childbirth have caused great damage to women's qi and blood, but she usually does not pay attention to maintenance, resulting in both qi and blood losses. In fact, the physiological function of women needs various hormones in the body to maintain, but the decline of ovarian function makes endocrine disorders, thus affecting the metabolic function of the human body. So women are more prone to aging than men.
Collagen is the most important component in the skin. Strong elasticity, criss-crossing to form a network structure, supporting skin tissue, providing enough tension and elasticity for skin. It can also store enough water to ensure that the skin is moisturized all the year round. The density of collagen in men's skin is higher than that in women's, which is one of the reasons why women's skin ages faster than men of the same age. Moreover, after the age of 30, the rate of collagen loss will be around 65,438+0% every year for both men and women. Within five years after menopause, the loss rate of collagen will obviously accelerate, and then it will drop to about 2% per year. In addition, women have to go through menstruation and childbirth, and the damaged uterus needs to be repaired. Endometrium is composed of collagen fibers and also needs a lot of collagen. So the reduction of collagen will make women look older.
Menstruation and fertility, estrogen deficiency, rare menstruation or even amenorrhea, decreased fertility or even infertility. The lack of estrogen in the skin mucosa system leads to wrinkles and long spots on the skin, decreased immunity of vaginal mucosa, urinary tract, respiratory tract and digestive tract, vaginal dryness, senile urethritis and repeated colds. Cardiovascular system, before menopause, estrogen protects women's cardiovascular system and is a "protective umbrella for women"; After menopause, women's cardiovascular disease, calcium content in midbone and bone determine whether the bone is strong or not, and estrogen is an important bridge of calcium metabolism in bone. When estrogen is deficient, calcium loss will lead to osteoporosis, which will be asymptomatic, continue to develop low back pain and even fracture. In the autonomic nervous system, the stability of body temperature, mood and sleep depends on estrogen. Estrogen deficiency can lead to hot flashes, sweating, irritability and depression, insomnia and dreaminess. It will be easier to get old! In fact, it is very important for women to develop good living habits in daily care, such as non-smoking, regular work and rest, good eating habits, paying attention to sun protection and skin care.
Researchers have revealed some innate laws that can make people live to three digits, and women have obvious advantages. 85% of centenarians are women. When a person is born will also determine his life span. Compared with babies born in spring, babies born in autumn are slightly more likely to live to 100. Researchers speculate that environmental factors that people are exposed to in early life lead to this difference. Pregnant women's intake of nutrients in winter is not very comprehensive, with less exposure to sunlight and less vitamin D synthesized by the human body. These factors have brought some long-term adverse effects on the health of babies born in spring. Have a long family. Thomas Bowles, an associate professor of medicine at Boston University, found that half of centenarians have immediate family members or grandparents. In addition to congenital and genetic aspects, researchers remind centenarians not to give up their good lifestyles and habits, otherwise they will give up all their efforts. It is true that there are genes at work in these elderly people's longevity, but it is also a misunderstanding to think that genes alone can live to 100 years old.
No smoking. Bradley willcocks is a Hawaiian longevity scientist. He is the medical director of the longest centenarian survey project in the world. His research team found that non-smoking increased the probability of living to 100 by seven times. Keep a slim figure. Reducing obesity means reducing the risk of various chronic diseases. Having a happy married life is conducive to maintaining a healthy attitude. Optimistic and open-minded. Most elderly people can skillfully relieve the pressure in work and life, and can quickly find a solution to the problem; Trouble will soon be eliminated from their minds, and they will not haggle over trifles; They are more emotionally stable, extroverted, diligent and more active in community activities.
