Aging is preventable.
After middle age, people's sleep quality is getting worse and worse, and they still feel exhausted during the day. This phenomenon is an early sign of aging.
Never, people are helpless about their aging. As the saying goes, "I don't know how old I am." Now, science has proved that "anti-aging system engineering" is feasible.
"Anti-aging system engineering" has two solid foundations: first, aging can be known and prevented early. Second, according to the laws of nature, the average natural life expectancy of people is 120 years old. Middle age is 60 years old, and what's more, it's 80 years old. Therefore, I am still the sun at 4 pm. This is no joke. Realistically speaking, aging should be divided into "natural aging" and "modern aging". Whether it is natural aging or modern aging, the mystery of the law has been scientifically revealed. Genetic theory explains natural aging, and the inevitability of natural aging is irresistible. At present, "anti-aging system engineering" is aimed at modern aging. Modern theories to explain aging include arteriosclerosis theory, free radical theory and biological clock theory. These causes can be prevented.
The biological clock is the "main oscillator" of the human body.
All biological species on the earth, whether it is animals or plants, whether it is the most primitive single-celled organism or the most advanced spirit of all things, have internal biological clocks. Because the celestial body keeps spinning, it produces a natural cycle. If organisms want to survive in nature for a long time, they must follow the natural cycle of geophysics and present various rhythms, such as circadian rhythm, seasonal rhythm, activity and dormancy rhythm, life and death rhythm and so on. These rhythms are preserved in the genetic code of the species. All inherited time rhythms, manifested in physiological functions, biochemical reactions and even morphological structures, should adapt to the rhythm changes in nature. In other words, the internal rhythm of living things must be synchronized with the natural cycle.
Biological evolution to advanced mammals, not only has a variety of organs, but also has many complete sets of functional systems, and it is necessary to keep the ever-changing rhythm in strict "synchronization", so it is bound to produce a "master oscillator". The biological clock is the "master oscillator" and plays an integrated role in the body. We can make an analogy: the biological clock is like the conductor of a symphony orchestra. He can mobilize hundreds of musical instruments and play the most complicated and beautiful music.
Human beings, the soul of all things, have a particularly developed brain. When the brain is excited, it can suppress the biological clock and make people stay up all night. Drugs to relieve sleep eliminate the excitement of the brain, thus releasing the biological clock and making people fall asleep. If the biological clock enters the aging process, human beings begin to enter the aging stage. In other words, the age at which a person begins to age can be measured by his "biological clock aging index".
However, it must be noted that the biological clock is not set in the brain, but in the neuroendocrine organ composed of hypothalamus and pineal gland. If the biological clock here drops, then sleeping pills can't produce sleep.
Melatonin secretion affects sleep and awakening.
As the saying goes, "you don't get enough sleep before you are 30, but you can't sleep after you are 30." Why is this? Is there a causal relationship between "before" and "after"? The mystery was solved by science. Only when people master their own sleep rules can they further learn "sleep management".
You should know that newborn babies have no vision and no regular night sleep. From 6 months, with vision, the pineal gland began to secrete melatonin. Under light, the pineal gland stops secreting; After turning off the lights, the pineal gland began to secrete. After 6 months, the secretion and production of melatonin gradually increased, reaching the peak of life at the age of 2.5. At this time, the child sleeps at night, and the pituitary gland begins to secrete auxin at night. The peak of melatonin secretion by pineal gland began to decline in adolescence; In middle age, the secretion of melatonin drops to half of the peak; In menopause, the production of melatonin varies from person to person, but the decline is an inevitable trend. Male menopause is late and the decline is slow. By the age of 80, most people's melatonin production has dropped to 10% of that of teenagers, and a few people still keep it above 10%.
During the day, "photography" can be converted into electric energy through the eyeball. So there is a nerve impulse to the sleep pacemaker, and then to the pineal gland to produce inhibition. When night comes, "photography" turns to "dark phase" and "light energy conversion" produces "electric energy" in the eyeball, so a nerve impulse is transmitted to the sleep pacemaker and then to the pineal gland to produce melatonin. Melatonin reaches the melatonin receptor of the sleep pacemaker from the blood, thus starting the sleep center and directing a series of active sleep processes. This explains how the circadian rhythm of the pineal gland manages the sleep and awakening of living things.
The serum concentration of melatonin in middle-aged healthy men was measured by radioimmunoassay: it increased slightly after 20: 00, accelerated at 2 1~22, reached the peak at 24~2: 00, decreased after 3: 00, and reached the lowest point at 7~8: 00 in the morning. During the day,
The pineal gland not only has neuroendocrine function, but also is a purification pool for eliminating free radicals in the brain. Melatonin produced by pineal gland is first consumed in the task of eliminating free radicals in the brain (Mt is eliminated after combining with free radicals in its own blood pool, and Mt is eliminated after combining with free radicals in the third ventricle).
Strong light can inhibit melatonin secretion from the pineal gland.
When modern people work under night lights, they often use strong light to suppress the pineal gland and cancel the production of melatonin at 20~22 o'clock. Nightlife began again after puberty. The production of melatonin at 0~2 was further eliminated. So, what will happen if the pineal gland stops producing melatonin? Free radicals in the blood pool of the pineal gland itself cannot be removed in time, and the purification pool becomes a pollution pool. Free radicals are cell killers, and the first victims are pineal cells. How long and how strong you are under the night light, your pineal gland will be damaged accordingly. Animal experiments show that continuous intense light irradiation leads to death, and all pineal cells disappear after dissection, which is equivalent to pinealectomy. Light cannot kill cells directly, but with the help of free radicals.
The pineal gland was inhibited by strong light, and at first it was functional interference. Often the melatonin secretion curve is delayed, that is, the biological clock is delayed by 2 to 3 hours. However, due to the exhaustion of nightlife, the pineal gland is dysfunctional due to free radical killing. Over time, the pineal gland can't protect itself, from functional atrophy to cell atrophy and calcification. This is the development process of biological clock disorder. Excessive consumption before the age of 30 will reduce the quality of sleep after 30. Excessive overspending may even lead to premature aging.
To sum up, the biological clock not only manages the "day" and "night" in your day, but also relates to your growth, development, fertility and aging in your life. Specifically, before middle age, it is a growth clock; After middle age, it is the clock of aging.
