It is difficult to say how long the symptoms of menopausal insomnia will end; the vast majority will end after about 0.5 to 2 years. Due to individual differences, some people will experience it for about 10 years before it ends. The decline in ovarian function and estrogen in the body during menopause can cause corresponding clinical symptoms, such as insomnia and dreaminess, hot flashes and excessive sweating, and changes in mood, which can be relatively irritable and emotionally unstable. The degree of clinical manifestation of these symptoms varies according to individual differences, as does the time of appearance and the time of end. Once menopause occurs, it is recommended that dietary modifications such as eating more estrogenic foods be given. In addition, taking part in social activities and exercising properly will help to relieve insomnia, and if necessary, oral medication can be taken.
