“While traditional Chinese medicine often emphasizes the potential long-term effects of excessive sexual activity, many do not realize that insufficient sex is also considered a cause of disease in Chinese medicine,” he added.
So, how often should you have sex to keep diseases at bay? Cheng cited the 2,000-year-old text “Su Nu Jing” for her answers.
According to the text, people in their 20s should have the most sex, planning an exciting intercourse every four days.
Things slow down as middle age progresses, with the text claiming that people in their 50s should have sex once every three weeks (21 days).
And while an apple a day might keep the doctor away, 60-year-olds who have sex just once a month could see the same benefits, according to the ancient sex book.
Those without a partner should not panic. Sex with “yourself” is just as valuable in preventing disease – as long as you have an orgasm.
However, medical experts have claimed that men and women should have orgasms more often than “Su Nu Jing” advises.
For men, research from Oxford University found that frequent ejaculations could be the key to avoiding prostate cancer.
A study of almost 32,000 men found that high levels of sexual activity can reduce the risk of prostate cancer by 33%.
The optimal number of ejaculations is 21 a month, or more than five times a week, the researchers insist.
Meanwhile, women should climax almost every other day.
Detroit doctor Andrea Pennington previously told UK talk show “This Morning” that women should have at least three orgasms a week.
“The benefits are many,” he said. “From stress relief to depression and anxiety, it makes us kinder and it’s a pain reliever.”
