The reasons why women are more prone to insomnia are mainly related to the unique physiological characteristics and personality traits of women. (1) The special physiological cycle of women. For example, during menstruation, pregnancy, childbirth, lactation, perimenopause, menopause, etc., women will experience changes in hormone levels that cause neurological and somatic symptoms, such as chest tightness, depression, sadness and crying, anxiety, irritability, and over-sensitivity. (2) Women tend to be more introverted, richer in emotions, and more delicate and sensitive to the experience of emotions. The above two points often become susceptible factors for female insomnia.
