Early pregnancy insomnia is mainly related to psychological factors, environmental factors, pregnancy reaction and so on. 1. Psychological factors: for some women in the early stages of pregnancy, insomnia can occur throughout the night due to excessive mental tension, anxiety or depression, overthinking, anger and rage. 2. Environmental factors: when the sleeping environment is noisy, inappropriate temperature and humidity, light stimulation, etc., can cause insomnia throughout the night for some women in early pregnancy. 3. Pregnancy reaction: In early pregnancy, nausea and vomiting, flatulence, frequent urination and other early pregnancy reactions can occur due to changes in hormone levels in the body. If the early pregnancy reaction is obvious at night, it will cause insomnia throughout the night. In addition to the above, too much excitement before going to bed, intake of stimulating food can also cause insomnia throughout the night in early pregnancy. For some long-term insomnia or other symptoms, we need to be alert to diseases, such as gastroenteritis, appendicitis, high blood pressure, cholecystitis, and so on. It is suggested that those who suffer from insomnia all night during early pregnancy should adjust their mindset to keep their body and mind happy, and should also create a good sleeping environment to improve the quality of sleep. If accompanied by other uncomfortable symptoms, should consult a doctor for examination, so as to clarify the cause of the disease and follow the medical advice.
