  • Take naps earlier in the day so that it does not interfere with night sleeping.
  • The bed should be used only for sleep and relaxation. Refrain from using the bed for activities such as reading a book, watching television, or working on your laptop.
  • Indulge in gentle exercising for at least 30 minutes each day if your doctor permits.
  • Indulge in a calming activity, such as reading a book, taking a warm shower, or meditation, for a few minutes before you go to sleep.
  • Drink plenty of water during the day but limit fluid intake two to three hours before bed so that you don’t have to wake up frequently during the night to pee.
  • Eat frequent, small, and easy-to-digest meals during the day. Avoid large amounts of spicy/acidic/fried foods or caffeinated drinks. Raise your head by using more pillows to alleviate the symptoms of GERD.
  • Turn off all screens at least an hour before bedtime.
  • Use a dim nightlight to make falling back to sleep easier after waking up at night to pee.
  • If you do not feel sleepy even after lying down in the bed for 30 minutes, get up, do some light activity and try to sleep again.
  • Write down your thoughts in a journal, or seek help from your partner, friends, doctor, or counselor.
  • Try and sleep on your left side and keep your knees and hips bent. Place pillows between your knees, under the abdomen, and behind your back as it helps in taking the pressure off your lower back. 

What Is The Best Sleep Position?

Sleeping becomes particularly difficult for women who are habituated to sleep on the stomach or the back. When pregnant, sleeping on the left side is the best position. It improves blood and nutrients flow to the fetus. You may tuck a pillow under the stomach for extra support. If you are not comfortable with sleeping on the left, you may also sleep on the right side.

After 28 weeks of pregnancy, falling asleep on the back may double the risk of stillbirth. However, in case you wake up on your back, do not worry. Shift your position to either side and go to sleep again (5).

When To See A Doctor? 

You must tell your healthcare provider if you notice any symptoms of insomnia. Lack of sleep during pregnancy may be linked to high blood pressure, preeclampsia, pre-term birth, and other pregnancy-related complications.

The doctor will check your blood pressure at your prenatal visits. If you experience severe headaches or swelling of your hands, ankles, or feet, your doctor may recommend additional tests.

The following are the symptoms of preeclampsia (6).

  • Severe headache
  • Blurred vision
  • Nausea
  • Vomiting
  • Not urinating frequently
  • Breathlessness
  • Abdominal pain on the upper right side

Although there are no proven risks of sleeping on the right, the advantages of left side sleeping make it a preference for many women (8).

3. Does the fetus sleep when the mother sleeps?

The fetus may or may not sleep when the mother does. From around 18 weeks of pregnancy, fetuses like to sleep while their mothers are awake since the movement helps rock them to sleep (9).
