Do you have a future soccer star who loves to practice their moves at 2:00 a.m.? Many prenatal discomforts including back pain, nausea, and fetal movements can result in sleepless nights. Insomnia symptoms include difficulty falling asleep, staying asleep, or waking up too early in the morning.

Fears and anxiety about labor, balancing work, and impending motherhood can also increase the likelihood of developing insomnia during pregnancy.

Pregnancy can be one of the most exciting times in a parent’s life, but that’s not to say it doesn’t come without its challenges.

Three children (and three pregnancies) later, I can speak from experience when I say that one of the most challenging symptoms that I was not prepared for was the lack of sleep.

There are many changes to a pregnant person’s body during the 9 months of pregnancy, and each trimester brings its own unique hurdles that can impact sleep. While a lot of focus is given to “eating for two” during this special time, more and more research is focusing on the underlooked importance of sleeping for two as well. Let’s explore some of the ways sleep is impacted during pregnancy and some tips on how to get more rest.

Body Changes During Pregnancy

There are many physical and psychological reasons why as many as 94 percent of women face challenges with sleep during pregnancy, according to research published in Obstetric Medicine1

While most of these changes are a natural part of the process, understanding how they impact rest can help you to better prepare and cope.

Women experience a roller-coaster ride of hormone changes during pregnancy. Dramatic changes in hormone levels2 may be behind some of the disruptions to sleep patterns mothers-to-be face. During the first trimester, estrogen and progesterone steadily increase, peaking at term and rapidly falling after delivery2 .


Progesterone has been shown to have a sedative effect, explaining why most women experience heightened fatigue during the first trimester when levels of this hormone surge2 . Both progesterone and estrogen have also been found to decrease rapid eye movement (REM) sleep3 , the important stage when the brain is consolidating information into long-term memories. 

Body Shape

As your little one begins to grow and occupy more space in the womb, the physical changes that announce your expecting status to the world become noticeable. In the first trimester, most women can keep their pregnancy a secret. Other than thicker hair and that coveted glow mamas-to-be display, most of the changes are happening inside of your body.


As the first trimester ends, the womb begins to expand to accommodate your baby’s rapid growth, and many pregnant people find that sleeping becomes more of a challenge. Getting into a comfortable position can be difficult, especially for those who are used to sleeping on their stomach or back. This is often the time when a pregnancy pillow becomes useful since it can provide support for your growing belly.


Not only does sleeping become uncomfortable due to your body's growth, but a common symptom of pregnancy, even in the earliest weeks, is the breasts becoming sore and swollen4 , which is quite painful. Research suggests that over 76 percent of pregnant people report breast pain at some point during the first trimester4 . Due to breast tenderness, stomach sleeping and even side sleeping can be increasingly uncomfortable during pregnancy.

During pregnancy, caloric needs increase by 300-500 calories a day5 , which explains why you may be so ravenous day and night. While not every expecting pregnant person craves pickles and ice cream, most do notice an increase in appetite very early on (or about the time when morning sickness finally goes away).


Nighttime hours are typically when growth and repair take place in the body, and this could explain why many cravings happen after the sun has set. For some women, hunger pangs can be a causes of interrupted sleep. 


In an online survey6 of 2,427 expecting mothers, 100 percent reported frequent nighttime awakenings. While craving a midnight snack isn’t the sole cause of these wakings, it is likely a contributor.

Energy Levels and Increased Fatigue

An increase in progesterone may be why many expecting mothers suddenly find themselves sleeping a lot of the time2 . During pregnancy, energy levels are also decreasing, making it hard to function day-to-day.


Napping can help some people temporarily increase their energy and make it through until bedtime, but for others, napping later in the day can make it more difficult to fall asleep that night. Oftentimes, the physical demands of growing a human being are so great that fatigue and lack of energy persist despite extra time in bed.

Increased Urination

Frequent trips to the bathroom are yet another commonly reported symptom mothers-to-be experience. In one study7 of 270 pregnant women, up to 77 percent experienced increased frequency of urination throughout all three trimesters. Nocturia (waking in the night to pee) was also reported by over 75 percent of women, further contributing to the interruptions in sleep that nearly all pregnant people face.

Illustration of Long Line-up to Use Women's Bathroom
There are many causes for increased urination including rising hormone levels, increased fluid intake, expanding blood vessels, and pressure on the bladder from the growing baby7 .


These are just some of the many questions that may keep expectant parents up at night. While some worrying is to be expected during this life-changing season, anxiety that impacts your daily life is not.

Anxiety8 is “an emotion characterized by feelings of tension, worried thoughts, and physical changes like increased blood pressure”, according to the American Psychological Association. Some of the signs of anxiety during pregnancy include loss of appetite, irritability, forgetfulness, difficulty sleeping, muscle tension, and trouble concentrating8. If you recognize any of these signs in yourself or a loved one, be sure to speak to your healthcare provider about treatment options.     Learn More: Anxiety and Sleep

Why is Sleep During Pregnancy So Important?

Good sleep is one of the most important things an expectant mother can do for her baby. Adequate rest is essential for a healthy pregnancy and full-term delivery. 

According to the American Academy of Sleep Medicine9 , without sufficient sleep, pregnant people “are more likely to have a depressed mood, attention and memory problems, excessive daytime sleepiness, more nighttime falls, and use more over-the-counter or prescription sleep aids, all of which may adversely affect the healthy development of her baby”

Progesterone Production:
Why it’s Needed

Progesterone10 is an essential hormone in the reproductive process, playing an important role in fertility and the maintenance of a healthy, full-term pregnancy. Early on, progesterone is produced by the corpus luteum, a temporary endocrine structure in the ovaries, and eventually, the placenta takes over production at around 8-10 weeks10 .


Progesterone is necessary for nurturing a healthy environment for the developing fetus and to prevent rejection by the mother’s body. This hormone is the reason why you suddenly have luscious locks and that coveted pregnancy glow.

Illustration of Process of Reproduction

Research has discovered that progesterone activates receptors11 in the brain that shorten the time it takes for the body to enter REM cycles and also decrease the amount of time spent in this phase [1]. With elevated levels throughout all three trimesters, this hormone may be to blame for your zombie-like state day and night. Even though this increases the difficulty of sleeping, it is still important to get enough sleep so your body can keep up with the progesterone production.

Gestational Diabetes

Gestational Diabetes Mellitus12 (GDM) is a form of diabetes that develops during pregnancy and causes elevated blood sugar levels that the body has a hard time controlling. This is also what doctors are testing for when you have to take that dreaded glucose tolerance test and drink that nasty orange beverage.


Women with (GDM) have an increased risk of developing preeclampsia, are more likely to require a C-section, and are at a greater risk for developing type 2 diabetes after giving birth12 . Babies born to mothers with GDM have an increased risk of macrosomia, hypoglycemia, jaundice, and birth-related injuries12. After birth, these infants are also more likely to develop metabolic syndrome, type 2 diabetes, and obesity later on in life12.


Based on research, decreased quality of nighttime rest has been shown to increase hyperglycemia (high blood sugar levels) and insulin resistance, which explains why gestational diabetes is more likely to occur in women who are not getting adequate rest12. So, make sure you’re sleeping enough in order to reduce your risk of developing gestational diabetes. 


Many expecting mothers have worried about the risk of developing preeclampsia13 . This condition is defined as having high blood pressure levels coupled with excess levels of protein in the urine after the 20th week of pregnancy13 .


Preeclampsia can pose serious threats to both mothers and babies, increasing their risks of serious complications and even death13 . Both snoring14 and sleep apnea15 have been shown to increase the risk of gestational hypertension, which can lead to preeclampsia.


A study16 found that women with preeclampsia experienced more insomnia, snoring, fragmented sleep, and sleep apnea than non-pregnant women. The women with preeclampsia also had higher rates of anxiety and depression than the control groups16 . If you’re pregnant and have preeclampsia, ensure that you’re getting sufficient sleep because it will definitely be more difficult for you than for those without preeclampsia.

Life After Baby

Many seasoned parents will warn expecting friends to “sleep now while you can.” While fatigue and restless nights can make mothers-to-be long for the days after delivery when they can finally rest in their favorite positions again, sleep after baby can be even more challenging.


Newborns have fragmented sleep patterns17 in the early days, waking frequently for feedings during the night. Babies who were used to being rocked to sleep by the daily movements of busy mothers may be born with their days and nights reversed. It can take weeks or months for the circadian rhythm to regulate in infants, and nighttime waking can continue into early childhood for some.

Common Sleep Disorders Caused or Made Worse During Pregnancy

Christine Won18   summed up the great irony of sleeping for two in pregnancy when she said, “Herein lies the great paradox of sleep in pregnancy — despite the seemingly imperative need for healthy sleep and our body's attempt to promote it, many of the normal physiologic and psychological changes accompanying pregnancy make restful sleep all but impossible.” [5]

Unfortunately, many sleep disorders19, such as sleep apnea or restless leg syndrome, can develop or be made worse during pregnancy, increasing the risk of developing hypertension, gestational diabetes, intrauterine growth restriction, and postpartum depression.


If you suddenly find yourself crying during a toothpaste commercial or snapping at your partner for no reason, you can blame your hormones. 

Estrogen and progesterone levels are extremely elevated during pregnancy compared to preconception levels. These hormone fluctuations coupled with other physical and psychological factors contribute to the higher prevalence of sleep disorders during pregnancy.

Pregnancy Insomnia

Illustration of a Baby Playing Football In Mommys Belly
Insomnia appears to be a very common struggle that many expecting mothers face with as many as “78 percent of women reporting that they experienced disturbed sleep during their pregnancy, according to a 2016 study20 .   Read More: How To Deal With Insomnia After Pregnancy

One study found that “At the beginning of pregnancy, the incidence of insomnia is lower at 12.6% and then increases as pregnancy progresses. Up to 73.5% of women display some degree of insomnia at a median of 39 weeks, further classified as mild in 50.5%, moderate 15.7%, and severe in 3.8%. In the last trimester of pregnancy, up to 69.9% reported difficulty in maintaining sleep, 34.8% described early morning awakenings, and 23.7% reported difficulty falling asleep1.”

Restless Leg Syndrome

Have you ever had that creepy-crawly feeling in your legs that you just can’t shake away?

Restless Leg Syndrome (RLS) is a sleep-related disorder that causes irresistible impulses to move your limbs (typically legs). Symptoms tend to be worse in the evening or at night and during prolonged periods of rest.


Restless Legs Syndrome21 is twice as likely to occur in females, possibly explaining why it is more common during pregnancy as well. The risk factors of Gestational RLS22 include a personal or family history of RLS, a history of growing pains, obesity, smoking, and snoring in the first trimester.


Although it may be tempting to just chalk this up as yet another symptom, RLS can be serious in some cases. A study23 of 231 women found that there was a two-fold increase in the risk of preterm birth among those with RLS. Preeclampsia is also reported to occur more in women with RLS21.

If you have ever been lying in bed and suddenly felt like a volcano is erupting out of your esophagus, you’re not alone. Gastroesophageal Reflux Disease24 (GERD) occurs more commonly in women who are expecting, with 30-50 percent reporting frequent heartburn. Pre-existing reflux, increased maternal age, and the amount of weight gained are all risk factors for developing GERD, and the more weight a woman gains, the higher her chances become24.
Heartburn, acid reflux, and GERD can all be blamed on those pesky hormone changes that relax the muscles in the esophagus, allowing stomach acids to rise and creating a burning sensation in the throat24. As your uterus expands to accommodate your growing baby even more pressure is placed on the stomach, making heartburn and reflux even worse24. All of these symptoms can make it very difficult to sleep well.

Sleep Apnea

Are you suddenly snoring like a log, causing your partner to take cover under their pillow? While some snoring is normal and could be due to more congestion, pauses in your breathing may be worth a trip to the doctor.


Sleep apnea occurs when the upper airways are partially or fully obstructed25 , decreasing oxygen saturation in the blood and resulting in brief arousals during the night. Although these episodes typically last for only 10-30 seconds, the compound effect they can have on the overall quality of rest is significant25.


 Nasal congestion, gestational weight gain, decreased lung volume, swelling or shortening in the esophagus and throat, and large abdominal mass are all contributing factors to the increased prevalence of sleep apnea during pregnancy.

13 Tips For Better Sleeping During Pregnancy

Creating a human being is hard work, especially if you are constantly tired and lethargic. Insomnia and fatigue can be challenging to cope with, especially when coupled with all of the other prenatal symptoms that can make sleep disturbances worse. Although it may be tempting to reach for an over-the-counter sleep aid or herbal supplement, we suggest you stay away from these products during pregnancy.


Instead, try these tips which may help to naturally improve the quality of your sleep:


Prioritize Rest

Schedule and plan times for rest into your day, even if it just means sitting with your feet up for five minutes every hour.


Maintain a Consistent Bedtime/Wake-up Time

Get into the routine of going to bed and waking up at the same time every day. This helps regulate the circadian rhythm and may make it easier to fall asleep quickly at night.


Practice Self-care

Now is the time to get into the habit of making self-care a priority in your life. Have a pedicure , take a bath, or get a low-maintenance hair makeover.


Get Some Exercise

Exercising for at least 30 minutes a day is a great way to improve rest at night. Yoga, walking, and swimming are all great choices, but be sure to check with your healthcare provider before starting any new exercise routine.


Prioritize Naps

Naps can be very rejuvenating when you are battling ongoing fatigue. Try to nap earlier in the day and keep naps to 30 minutes or less to avoid disturbing nighttime rest.



Anxiety about your impending delivery and motherhood can keep you up, worrying all night long. Use relaxation techniques to clear your mind like talking to a trusted friend, practicing your faith, journaling, or spending time in nature.


Start Side Sleeping Early

Obstetricians recommend that women sleep on their left side during pregnancy to maximize the flow of blood and nutrients to the baby. Re-conditioning the body to sleep in a new position takes time, so start training yourself to sleep on your side early, before it becomes necessary.


Avoid Big Meals Before Bed

While it may be tempting to give in to late-night cravings, eating large amounts of food before bed can increase reflux and heartburn. Instead, focus on eating healthy foods earlier in the day, eating a lighter dinner and a small snack in the evening.


Avoid Lots of Fluids Before Bed

If you want to decrease the number of times you wake up in the night to use the restroom, try to avoid consuming large amounts of liquid before bedtime. Do stay hydrated throughout the day, though.


Establish a Bedtime Routine

Creating a consistent bedtime routine helps your brain recognize when it’s bedtime. Some rituals you can incorporate into this routine are meditating, reading, lighting a candle, or taking a bath.


Use a Pregnancy Pillow

Investing in a pregnancy pillow will hopefully help make side sleeping more comfortable. Check out our favorite pregnancy pillows.


Cut Back on Caffeine

Drinking caffeine before bed can delay the time you fall asleep, so if you do choose to drink caffeine during pregnancy, try to consume it earlier in the day so it doesn’t affect your sleep.


Avoid Blue Light at Night

We suggest that nobody expose themself to blue light before bedtime because it can trick your brain into thinking it’s daytime. So, with all of the other factors that can negatively impact your sleep during pregnancy, try not to add blue light on top. Instead of using electronics, read a book or meditate before bed.


When Should I See My Doctor?

The body is undergoing tremendous changes during pregnancy, and many symptoms like morning sickness and frequent urination are to be expected. However, if you notice that your legs are shaking excessively, you have changes in snoring, your legs and feet are abnormally swollen, or you are experiencing severe headaches, you should speak to your doctor as these could be signs of high blood pressure or other serious complications.

Good Questions for Your OB

What sleeping aids are safe for me?

While most sleeping aids are not approved for use during pregnancy, your doctor may know of over-the-counter or prescription options that have been deemed safe for you.

Is it ok to exercise?

Exercise can be a great way to stay healthy and strengthen your body for delivery. In some cases, exercise may not be safe for all expecting mothers. Speak to your doctor about what types of exercise may be best for you.

What vitamins can help my symptoms?

Growing a baby is hard work for your body, and nutrient needs are at an all-time high. Aside from your daily prenatal, some vitamins can cause harm if taken in large quantities, so always check with your doctor before taking any additional supplements.

Am I sleeping too much?

Getting adequate rest is important for the health of you and your baby. Excessive sleep can be normal in many cases, but if you are worried, speak with your doctor about the number of hours you are sleeping in a day.

What snacks might help me sleep?

Certain foods are high in naturally occurring melatonin, a hormone that helps you sleep. Foods that contain protein and fat are also satiating and may prevent frequent wakings caused by hunger. Your doctor may be able to recommend some good bedtime snack choices as well.



Is there such thing as sleeping too much during pregnancy?

Several studies27 have confirmed a link between sleeping in positions other than the left side and an increased risk of still-births, but a 2019 study28 also found that excessive sleep, which is considered more than nine hours per night, was also associated with a greater number of later-term still-births. While research is still ongoing, you should speak to your doctor if you are concerned about the number of hours you are sleeping and the possible risks for your baby.

Can my sleep predict what kind of labor I’m going to have?

Sleep disturbances in late pregnancy have been associated with delivery type and length of labor. In a study29 with women in their third trimester, researchers found that “women who slept less than 6 hours at night had longer labors and were 4.5 times more likely to have cesarean deliveries. Women with severely disrupted sleep had longer labors and were 5.2 times more likely to have cesarean deliveries.”

When should I stop sleeping on my stomach during pregnancy?

Around the second trimester of pregnancy, sleeping on your stomach will likely become really uncomfortable as your belly is growing. Try sleeping on your side, as it will probably be more comfortable and it’s also the safest sleeping position for the baby.

When should I stop sleeping on my back during pregnancy?

You should stop sleeping on your back once you reach the second trimester of pregnancy in order to ensure the safety of your baby. Sleeping on your side is the safest position for the baby in your belly.


Pregnancy can be a special time in your life and one that you will look back on for years to come. This 9-month period can be full of joyful anticipation, but if you are struggling with sleep disturbances and fatigue, you may long for these days to end.


Spoiler alert for all you parents-to-be: the sleepless nights don’t end after pregnancy. Developing good sleep habits now will help you to cope with the many sleepless nights that are to come. 


Adequate rest is not only helpful for managing low energy and fatigue but is essential for a healthy pregnancy and delivery. The best gift you can give yourself and your baby is a good night’s sleep.
