Better sleep – better sex

Poor sex in middle-aged women linked to sleep disorders

Ruzana Ancek, N+1

American doctors have found that lack of sleep negatively affects the quality of sexual life of women during menopause. At the same time, the quality of a night's sleep is crucial, not its duration. The survey was conducted among middle-aged women who have complaints about sexual problems. The work was published in the journal Menopause (Kling et al., Associations of sleep and female sexual function).

Sleep problems occur in women on average more often than in men, and during the premenopause (45-60 years) they begin to bother even more. 26 percent of middle–aged women complain of insomnia and more than half - of other sleep disorders. Up to 43 percent report sexual problems during the same period of life.

Previous studies have already tried to determine whether there is any connection between sleep disorders and sexual dysfunction. Understanding the interdependence between poor sleep and difficulties in the intimate sphere is very important to identify potential treatment options for these common problems that significantly worsen the quality of life of women during menopause.

Dr. Juliana Kling from the Mayo Clinic and her colleagues conducted a survey among women who sought advice about menopause or sexual health at the Mayo Clinic from December 2016 to September 2019. The relationship between sleep quality, sleep duration and sexual dysfunction was evaluated using a multidimensional logistic model. The secondary analysis assessed the quality of sleep by sexual activity, and also included sexually inactive women. A total of 3,433 women took part in the study (average age 53 years).

The results showed that women with poor sleep quality were 1.48 times more likely to report sexual dysfunction (95 percent CI 1.21-1.80, P < 0.001). Of the participants who slept less than five hours a day, 63.3 percent had sexual problems, and their overall index of sexual activity and indicators for the subject area were significantly lower than those who slept more than seven hours at night (P = 0.004); however, statistically, this did not matter in multivariate analysis. Thus, the researchers concluded that for healthy sexual activity, it is more important for middle-aged women to sleep better and stronger than for a long time.

Regular sex life, in turn, can delay the timing of menopause. The more often a woman has sex, the longer her menstrual cycle lasts. Scientists have suggested that the body may consider the absence of intimate relationships, respectively, the chances of getting pregnant, a signal to stop wasting energy on ovulation.
