The difficulty in sleeping at night in early pregnancy is mainly related to the hormonal changes in the body after pregnancy and the psychological state after pregnancy. In the early stage of pregnancy, human chorionic gonadotropin, estrogen and progesterone change significantly, causing physiological changes in the body’s digestive system, urinary system and other organs and tissues. Neurological and psychological changes may also occur, such as drowsiness, irritability, excessive psychological stress, nervousness and even anxiety, which may affect normal sleep. It may be difficult to fall asleep or wake up easily after falling asleep, and poor sleep quality may cause fatigue. Secondly, during early pregnancy, pregnancy reactions such as nausea, vomiting, reduced appetite and other gastrointestinal discomfort can also affect sleep due to the secretion of large amounts of human chorionic gonadotropin. To promote sleep, it is recommended to soak your feet in warm water before going to bed, drink warm milk, read a book or listen to soothing music to relax.
