Why does a pregnant woman keep waking up intermittently during sleep, and what should be done about it?

Generally, pregnant women may frequently wake up during sleep due to hormonal changes, discomfort from uterine enlargement, anxiety during pregnancy, leg cramps in pregnancy, or pregnancy-related rhinitis. It is recommended to seek medical advice promptly, identify the underlying cause, and improve sleep under a doctor's guidance using safe measures. Specific explanations are as follows:

1. Hormonal changes: After conception, fluctuations in estrogen and progesterone can interfere with the sleep cycle, leading to lighter sleep and frequent awakenings. Avoid electronic screens one hour before bedtime; soak feet in warm water for 10 minutes, drink half a cup of warm milk to help relax the body and mind and promote deep sleep.

2. Discomfort from uterine enlargement: As the uterus enlarges, it may press on the bladder causing increased nighttime urination, or compress the lower back and abdomen, resulting in soreness and disrupted sleep. Reduce fluid intake two hours before bedtime. Sleep on the left side and place a soft pillow between the waist and abdomen to reduce uterine pressure and relieve discomfort.

3. Anxiety during pregnancy: Worries about fetal health or childbirth can lead to mental tension, difficulty falling asleep, and frequent awakenings. Communicate daily with family members to relieve emotional stress. Listen to soothing prenatal music before bed, and seek help from a professional psychologist if necessary.

4. Leg cramps during pregnancy: Leg cramps caused by calcium loss or poor blood circulation during pregnancy can wake a woman suddenly and make it difficult to fall back asleep. Consume calcium-rich foods such as milk and soy products daily. Take calcium supplements such as calcium carbonate D3 tablets, calcium gluconate oral solution, or calcium lactate granules as directed by a physician. Massage legs before bedtime to improve circulation.

5. Pregnancy rhinitis: Nasal mucosa congestion and swelling during pregnancy can cause nasal blockage, forcing mouth breathing and reducing sleep quality. Use a saline nasal irrigator to clean the nasal passages, maintain indoor humidity at 50%-60%, and use physiological seawater nasal sprays, mometasone furoate nasal spray, or loratadine tablets as prescribed to relieve symptoms.

Maintain a regular daily routine by going to bed and waking up at consistent times each day, and avoid long naps during daytime. Eat light, easily digestible meals and avoid spicy food or overeating before bedtime. Keep the bedroom quiet and dark, and create a comfortable sleeping environment to improve sleep quality.
