What is the impact of frequent human life in the elderly? Human life in the elderly has seven major functions

"People want their retirement life to be rich and colorful, so they have arranged for travel, calligraphy training, planting flowers and grass... but few people believe that sex life is also included.". Sex is not the exclusive right of young people. According to a survey conducted in the United States, about 75% of 57-64 year olds believe that sex is passionate about their retirement life. Therefore, the American Association of Retired Persons has published in its official magazine seven reasons why we should have sex after the age of 50.

1. Sex is good for sleeping. After the age of 50, both men and women may experience problems with decreased sleep quality, and sexual life can prolong sleep time, improve sleep quality, and help treat sleep disorders such as insomnia. The reason is that sexual excitement and orgasm help the brain release more oxytocin, lower levels of the stress hormone cortisol, and shut down brain regions related to stress, fear, and anxiety. Dr. Roger Ikki, an expert at Virginia Tech University, said that after sex, it is easy to enter and extend the deep sleep phase (fast eye sleep to recharge the body).

2. Help identify health issues and enjoy happiness. Dr. Christine P. Mark, director of the Sexual Health Promotion Laboratory at the University of Kentucky, said that periodicity is a mirror of health and can help identify many health issues. At the same time, as women age, they significantly feel more likely to have orgasms, and the quality of orgasms also significantly improves. Expert analysis pointed out that the accumulation of experience and the fact that couples no longer worry about physical problems are two important factors for older people to enjoy sex.

3. Looks younger. Dr. David Wicks, a neuropsychologist at the Royal Edinburgh Hospital in Scotland, conducted a new study of 3500 participants aged 18-102. Compared to those who had sex twice a week, those who had sex at least three times a week looked 10 years younger. One possibility is that the body releases various healthy hormones during sex. Another possibility is that people with high frequency of sexual intercourse pay more attention to appearance and anti aging, so they often exercise and pay attention to a healthy diet.

4. Reduce the probability of vaginal dryness in women. GD is short for female genital dryness. According to Dr. Lawrence Taicher, a gynecologist at Northwestern University in the United States, a normal sexual life after amenorrhea makes women look younger. Sexual stimulation increases vaginal blood flow and improves the lubrication and elasticity of the vaginal wall. Having sex two or three times a week can help improve women's vaginal dryness.

5. Reduce the risk of prostate cancer in men. A large-scale study involving 29000 participants published in the Journal of the American Medical Association found that among men aged 46 to 81, those who ejaculated the most (21 times per month) had fewer prostate cancers than those who ejaculated the least (less than 7 times per month). One theory is that infrequent ejaculation can easily lead to the accumulation of carcinogens in the prostate, while regular ejaculation can flush out more carcinogens in the body, reducing the risk of prostate cancer.

6. Strengthen marital relationships. In 2014, the University of Chicago's National Poll Center conducted a new study on 500 couples aged between 58 and 85. After 40 years of marriage, sexually active couples also have high marital satisfaction. Even a slight improvement in sexual activity (from asexuality to having sex once a month, for example) can improve marital happiness. Dr. Linda Waite, the lead author of the new study, said that "sex" does not necessarily mean sexual intercourse, and the act of expressing intimacy between couples can also play a similar role.

7. Improve happiness in later life. A new study by Tim Wadsworth, an associate professor of sociology at the University of Colorado, published in the journal Social Indicators Research, found that the more sexual activity, the higher overall happiness. Participants who had sex two or three times a week were 33% happier than those who had not had sex in the past year. When people know that they have sex more frequently than their peers, their happiness is higher.
