Insomnia occurs more frequently in women than in men for more than three reasons, including changes in various physiological, psychological, and environmental factors, as well as medications, neuropsychiatric and somatic disorders. Common causes are as follows: 1, family history: the incidence of insomnia in those with a family history of insomnia is three times higher than in those without a family history; this is equally evident in both men and women. 2, mental factors: women are psychologically sensitive and prone to perfectionist personality, resulting in easy anxiety, irritability, mental disorders and other situations that seriously affect sleep; 3, stress factors: changes in the sleep environment or life, work stress leading to mood swings, poor tolerance, etc., some early awakening at night after rumination leading to difficulty in maintaining sleep. Women are more obvious. 4, habits: pillow discomfort or wrong sleep posture, usually a lot of coffee, tea, too full or too hungry, too long bedtime during the day or irregular rest and rest, etc.; 5, physiological factors: with the gradual growth of age, the sleep regulation center degenerates, the stability of sleep becomes less stable, and insomnia is gradually higher. Due to the physiological characteristics of women, as they grow older and gradually experience pregnancy, lactation and menopause, they are more prone to endocrine disorders, causing insomnia; the rise and fall of hormone levels in women’s menstruation, pregnancy and menopause can also affect sleep. Therefore, insomnia is the end result of a variety of complex factors, and women are more likely to be affected for more than three reasons.
