The term “vacation” is generally used to refer to menstruation. Women who are particularly sleepy before menstruation may be experiencing pregnancy, or it may be due to excessive physical work, anemia, etc., which needs to be analyzed specifically. 1. Pregnancy: After pregnancy, the body’s energy consumption is greater, which may lead to nutritional deficiencies and symptoms of sleepiness and discomfort. 2. Excessive physical labor: If a woman has performed heavy physical labor before menstruation and has not received sufficient rest, it may lead to drowsiness. 3. Anemia: If a woman has anemia, it may lead to insufficient supply of oxygen to the brain tissue, which may manifest as drowsiness and fatigue. If a woman’s unusual drowsiness persists and cannot be relieved, it is recommended that she go to the hospital in a timely manner and receive standardized treatment under the guidance of her doctor in order to promote the relief of physical discomfort as soon as possible and to clarify whether or not pregnancy has occurred under the guidance of her doctor.
