That is to say

Women generally live longer than men

So

Why do women age faster than men?

And why do women live longer than men?

Let me show you today

1

Why do women age faster than men?

There are great differences between men and women in anatomy, physiology, etc., such as women's menstruation, pregnancy, breastfeeding, and hormones. With the increase of age, the estrogen level of women decreases, the rate of collagen loss is higher than that of men, the phenotype of skin cells changes, and signs of skin aging appear.

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

Menopausal women may experience endocrine disorders, decline in physiological functions, and many chronic diseases such as osteoporosis and cardiovascular diseases. And the level of male androgen drops by about 10%-20% every year, and the transition of male menopause is generally relatively smooth, so the aging process is relatively slow.

Bad living habits and indulgent lifestyle are important reasons for inducing diseases and accelerating aging.

The social functions performed by men and women also differ. Some women have to take care of their families while working. Due to the accelerated pace of life, increased survival pressure, lack of regularity in lifestyle, neglect of physical exercise, and long-term negative emotional stimulation, it is one of the reasons for accelerated aging of women.

Why do women live longer than men?

According to the big data statistics of the world population, women generally live 5 to 10 years longer than men.

①Women have a biological advantage

Female sex chromosomes are XX and male sex chromosomes are XY. Oxygen free radicals affect the healthy lifespan of human beings, and enzymes that scavenge oxygen free radicals are located on the X chromosome. Therefore, women with two X chromosomes produce more of this enzyme, which scavenges more oxygen free radicals.

② The shortening rate of male telomere length is faster than that of female

Telomere length is affected by many factors such as oxidative stress, inflammatory response, chronic disease, smoking, exercise and psychology. Telomere length shortens at a faster rate in males compared to females.

③ Some women's living habits are healthier than men's

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

How to delay aging?

Aging is inevitable in life, but we can delay the aging process:

①Change unreasonable lifestyle and 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, thereby reducing the occurrence of diseases and prolonging life.

③ Eat a reasonable diet, quit smoking and limit alcohol, ensure adequate sleep, and adhere to moderate aerobic exercise.

④Pay attention to the cultivation of psychological adaptability and tolerance to complex social environments, and maintain an optimistic and cheerful mood.
