What is aging? Three stages of human aging

Aging is a natural law. As time goes by, everyone has signs of aging. For example, skin dehydration, dry skin, wrinkles, pigmentation, memory loss, hair loss, and decreased immunity are all signs of aging that appear slowly. Although everyone is unable to resist aging, we can understand the causes of aging, and through a healthy lifestyle and healthy nutrition, we can develop healthy living habits as early as possible, eliminate the aging process, make our daily life more quality, and ensure anti-aging. Causes of decline: Decline has been with us since the moment we were born. Why do people age? Modern science's understanding of the causes of ageing is: 1) Excessive oxidation. Excessive oxidation damage to the body can accelerate aging, illness, and death, cause rapid tumor growth, cause inflammation and autoimmune reactions that damage health, and cause pigmentation and the appearance of spots. 2) The lifespan of somatic cells: The gaps in somatic cells being filled with metabolic waste can also cause cell aging. Sudden changes in somatic cells and chromosomal aberrations can also cause decline. Common causes include electromagnetic radiation, radiation damage, etc. 3) Decline leads to decline of the whole body. Mental shock can cause sudden decline, which shows that the brain center has a great influence on decline. Some people will quietly pass away not long after their loved ones pass away. This is a typical example of degeneration being affected by the nervous system. 4) The possible ways of protein degradation are: errors in protein synthesis, nucleoprotein degradation, and abnormal genes that cause protein synthesis obstruction, leading to life decline. 5) Decreased function of the endocrine system. Some experts and scholars believe that the decrease in the functions of sex hormones, thyroid cysts, adrenaline, pituitary gland, etc. will induce rapid decline of the body. For example, patients with thyroid disease are very prone to aging. In recent years, the idea that thymus shrinkage promotes the aggravation of degeneration has increasingly attracted the attention of experts and professors. 6) Microcirculation disorder Due to the accumulation of a large number of metabolic wastes in the body and the adhesion of physiological metabolic residues, a large number of capillaries are damaged, resulting in the narrowing or even closure of the blood vessel lumen, causing obstruction of blood circulation and circulatory system, restricting the exchange activities of metabolism, and causing cell degeneration. 7) Lack of androgen Androgen plays a buffering role in the stability of extracellular fluid in the body's basic metabolism, the harmony between organs, and its production, growth, development, and reproduction. Androgen maintains the normal functioning of the human body. If androgen is out of balance, it will cause physiological function to decline and lead to various inappropriate symptoms. For example: irritability, mood swings, insomnia, memory loss, pain, wrinkles, and pigmentation. The outflow of male hormones and physiological pain accelerate the decline of the body. In addition, self-poisoning and malnutrition also cause human decline. The process of physical decline is divided into three stages. The first stage: slight decline. 25-35 years old. Lack of vitality, physical strength, withering, fatigue, memory loss, prone to fever and cold, poor sleep quality, poor appetite, dull skin, pigmentation, and low immunity. Mild wrinkles appear in the second stage: mild to moderate decline 35-45 years old mood swings, irritability, anxiety, insomnia, suspicion, memory loss, menstrual disorders, low libido, breast shrinkage, abdominal distension, more severe pigmentation, dry skin, reduced elasticity, enlarged pores on the face, aggravated wrinkles, and sweating. Mild to moderate wrinkles Stage 3: Severe decline The body enters a period of rapid decline between the ages of 45 and 55, with all aspects of the body aging and various symptoms. After menopause at around 45 years old, women experience ovarian atrophy, decreased estrogen secretion, dehydrated and wrinkled skin, sagging breasts, and body fatness, which are more prone to psychological anxiety, depression and other mental illnesses. Women are entering a period of rapid aging and will enter the elderly state! Moderate to severe wrinkles
