Date:2022-03-15 Topics : Research Dynamics

      Aging is a process that everyone has to go through in his life. With the increase of age, the structure and function of various tissues and organs of the body change. The decline of the body is the result of many factors inside and outside the body. There are differences between men and women in physiological, psychological and social functions. The aging of women has more complex characteristics and rules than men.

      Data show that: as nearly half of the world's population, women are more likely to show signs of aging than men. In China, about 90% of women show signs of premature aging. We often find that many women do age faster than men in our daily life.

      However, big data shows that women live longer than men. According to the World Health Statistics 2019 of the World Health Organization, the life expectancy of women is 74.2 years, while that of men is 69.8 years.

      In China, the average life expectancy of women is 77.6 years, while that of men is 74.6 years, that is to say, women's life expectancy is generally longer than men's.

      So why do women age faster than men? Why do women live longer than men? Let's take you to know today.

      Why do women age faster than men?

      There are great differences in anatomy and physiology between men and women, such as menstruation, pregnancy, lactation and hormones. With the increase of age, the level of estrogen in women decreased, the rate of collagen loss was higher than that in men, the phenotype of skin cells changed, and the signs of skin aging appeared.

      Female menopause mostly occurs between 45 and 50 years old, and a few women begin to enter menopause at 40 years old, while male menopause mostly occurs between 55 and 60 years old, and the climacteric symptoms of women are significantly more than men.

      Menopausal women may have endocrine disorders, physiological decline, and many chronic diseases such as osteoporosis, cardiovascular disease also occur. The androgen level of men decreases about 10% - 20% every year. The transition of male menopause is generally stable, so the aging process is relatively slow.

      Bad living habits and indulgent lifestyle are the important causes of diseases and accelerated aging.

      Men and women also have different social functions. Some women have to take care of their families while working. One of the reasons for women's aging is the acceleration of the pace of life, the increase of survival pressure, the lack of regular lifestyle, the neglect of physical exercise and long-term bad emotional stimulation.

      Why do women live longer than men? According to the world population statistics, women's general life expectancy is 5-10 years longer than that of men.

      ① Women have a biological advantage.

      The female sex chromosome is XX, while the male sex chromosome is XY. Oxygen free radicals affect the healthy life span of human beings, and there are enzymes that scavenge oxygen free radicals on the X chromosome. As a result, women with two X chromosomes produce more of this enzyme and scavenge more oxygen free radicals.

      ② The shortening rate of telomere length in men is faster than that in women.

      Telomere length is affected by many factors, such as oxidative stress, inflammation, chronic diseases, smoking, exercise and psychology. Compared with women, the shortening rate of telomere length in men is faster.

      ③ Some women have healthier living habits than men.

      Compared with women, some men have more bad living habits, such as smoking and drinking, irregular work and rest time, unreasonable diet and so on.

How to delay aging? Aging is inevitable in life, but we can delay the process of aging

      ① Change the unreasonable way of life, eliminate bad habits.

      ② Choose a good living and working environment, or take measures to reduce the impact of environmental pollution on the human body, so as to reduce the occurrence of diseases and prolong life.

      ③ Reasonable diet, quit smoking, limit alcohol, ensure adequate sleep, adhere to the right amount of aerobic exercise.

      ④ Pay attention to the cultivation of psychological adaptability and tolerance to complex social environment, and keep optimistic and cheerful mood.
