Quick answer: To sleep better during pregnancy, adjust your sleeping position as your body changes, use pillows for support, maintain a consistent bedtime routine, and address symptoms such as heartburn, frequent urination, and back pain. During later pregnancy, especially from around 28 weeks, starting sleep on either your left or right side is generally recommended; if you wake up on your back, simply turn onto your side. Persistent insomnia, loud snoring with breathing pauses, or unusual daytime sleepiness deserves medical assessment. Seek urgent care for concerning pregnancy symptoms rather than trying to manage them with sleep adjustments alone.
Pregnancy can change your sleep long before your growing belly makes it difficult to find a comfortable position. You may feel exhausted during the day, wake repeatedly at night, or notice that a previously reliable bedtime routine no longer works.
These changes have several possible causes. Hormonal shifts, physical discomfort, nighttime bathroom trips, digestive symptoms, and emotional stress can all influence how long and how well you sleep.
The right approach also changes as pregnancy progresses. A routine that feels comfortable at 10 weeks may need adjustment at 30 weeks, and a sleep problem that seems ordinary may sometimes warrant professional evaluation.
A useful way to approach pregnancy sleep is Trimester → Symptom → Position & Routine → Medical Review. Start with your stage of pregnancy, identify the main disturbance, try an appropriate adjustment, and involve your prenatal care team when needed.
Sleep difficulties during pregnancy are common, but they do not follow exactly the same pattern for everyone.
Some people become noticeably sleepier during the first trimester, feel more comfortable in the second, and experience more nighttime awakenings toward the end of pregnancy.
Others have insomnia, nausea, anxiety, or physical discomfort across several stages.
During early pregnancy, rising reproductive hormone levels and other physiological changes can contribute to daytime fatigue.
Progesterone is involved in several pregnancy-related changes and may contribute to increased sleepiness. However, pregnancy-related fatigue has multiple causes and cannot be explained by one hormone alone.
Common first-trimester sleep disturbances include:
Some people may need additional opportunities to rest during this period.
Others feel tired but have difficulty falling asleep. Physical fatigue and sleepiness are related but different experiences, and both can occur during early pregnancy.
If nausea, vomiting, or exhaustion prevents you from eating, drinking, or functioning normally, contact your prenatal care team rather than assuming the symptoms are simply part of pregnancy.
Many pregnant people report improvements in nausea and daytime energy during the second trimester, although this does not happen for everyone.
As the uterus grows, sleeping positions may become less comfortable. Someone accustomed to sleeping on their stomach or back may begin exploring side sleeping.
Other possible disturbances include:
This can be a useful time to experiment with pillow support and establish an evening routine that remains comfortable as pregnancy progresses.
Sleep problems should not automatically be dismissed because they occur during the second trimester. Persistent insomnia, uncomfortable leg sensations, and changes in breathing during sleep can warrant medical evaluation at any stage.
During the third trimester, the growing abdomen can make it harder to settle into a comfortable sleeping position.
Pressure on the bladder, heartburn, musculoskeletal discomfort, fetal movement, and nighttime contractions may contribute to repeated awakenings.
Some people also experience more intense fatigue because their nighttime sleep has become fragmented.
As pregnancy advances, side sleeping generally becomes the preferred starting position for sleep. Support under the abdomen and between the knees can improve comfort.
However, no pillow arrangement can eliminate every pregnancy-related sleep disturbance.
If sleep problems become severe, discussing them with your obstetrician, midwife, or another qualified prenatal care professional is more useful than continually changing pillows without identifying the cause.
| Pregnancy stage | Common sleep concerns | Useful starting approach |
|---|---|---|
| First trimester | Fatigue, nausea, urinary frequency, emotional changes | Protect sleep opportunity, rest when needed, and address nausea or other symptoms. |
| Second trimester | Changing sleep positions, discomfort, heartburn, possible sleep disorders | Introduce comfortable side-sleeping support and assess persistent disturbances. |
| Third trimester | More nighttime awakenings, abdominal pressure, back or hip pain, leg symptoms | Start sleep on either side, use supportive pillows, and discuss significant symptoms with your prenatal team. |
These are common patterns, not fixed stages that every pregnancy follows. Your medical history, symptoms, and individual pregnancy circumstances may lead to different recommendations.
Sleeping position is one of the most frequently discussed concerns during pregnancy.
Advice can also be confusing, particularly when different sources recommend sleeping exclusively on the left side or suggest that accidentally turning onto your back is dangerous.
The evidence is more nuanced.
Side sleeping is generally recommended as pregnancy progresses, and both the left and right sides can be appropriate.
The left side is sometimes emphasized because body position can influence circulation and because left-side sleeping may help reduce nighttime acid reflux.
However, there is no requirement for every pregnant person to remain exclusively on the left side throughout the night.
If your left hip becomes uncomfortable, switching to the right side may help redistribute pressure.
Alternating sides can also make it easier to manage shoulder discomfort or maintain a comfortable position.
Unless your prenatal care professional has given you specific instructions, the goal is to find a supported side position rather than force yourself to remain motionless on one side.
As pregnancy advances, the weight of the uterus can place pressure on major blood vessels when someone lies flat on their back.
In some people, this can reduce blood return to the heart and contribute to dizziness, nausea, or lightheadedness.
Research has also investigated whether going to sleep on the back in later pregnancy is associated with adverse pregnancy outcomes.
Observational studies have linked going to sleep on the back after approximately 28 weeks with a higher risk of stillbirth. This association has informed recommendations to begin sleep on either side during later pregnancy.
However, studies differ in design and the stages of pregnancy they examine.
For example, a large prospective study examining sleep position in early and mid-pregnancy did not identify the same association through the period studied, which extended to approximately 30 weeks. Those results cannot conclusively establish the risks of sleeping positions across the entire late third trimester.
A practical approach is to begin sleep on your left or right side during later pregnancy, especially after 28 weeks, unless your prenatal clinician recommends a different arrangement.
If you wake up on your back, do not panic. Simply roll onto your side and return to sleep.
You do not need to remain awake monitoring your position throughout the night.
If lying flat causes dizziness or other symptoms, change position and discuss persistent or concerning symptoms with your prenatal care team.

During early pregnancy, sleeping on your stomach may remain comfortable for some people.
As the abdomen grows and breast tenderness or pressure increases, this position often becomes uncomfortable or impractical.
There is no need to force a stomach-sleeping position if it causes discomfort.
Switching gradually to side sleeping can make the transition easier as your body changes.
Individual medical circumstances may affect positioning recommendations, so follow any specific guidance from your prenatal care professional.
You do not necessarily need a specialized pregnancy pillow. Ordinary pillows can provide useful support when arranged appropriately.
Keep your knees comfortably bent rather than pulling them tightly toward your chest.
If a pillow increases pressure, numbness, or discomfort, adjust its position or remove it.
The ideal setup is the one that helps you remain reasonably comfortable while following the positioning guidance appropriate for your pregnancy.
For a broader comparison of ordinary side, back, and stomach positions, see our guide to the best sleeping position. Pregnancy-specific advice in this article and recommendations from your prenatal clinician should take priority over general sleep-position guidance.
Finding a comfortable position is only part of the solution.
Many pregnancy-related sleep problems have a specific underlying trigger, and the most appropriate adjustment depends on that trigger.
Hormonal, circulatory, and anatomical changes during pregnancy can increase urinary frequency.
As the uterus grows, pressure on the bladder may make the urge to urinate more noticeable, including during the night.
To reduce avoidable disruptions:
Do not deliberately dehydrate yourself to avoid waking up.
Adequate hydration remains important during pregnancy, and your needs may change with activity, temperature, nausea, and other factors.
If urination causes burning, pain, fever, or other urinary symptoms, contact your prenatal care team to assess for a possible urinary tract infection.
Heartburn is common during pregnancy because hormonal changes can affect digestion and the growing uterus can increase pressure on the stomach.
Symptoms may worsen when lying down soon after eating.
Practical adjustments include:
These changes may improve comfort but are not guaranteed to eliminate reflux.
If heartburn remains frequent or severe, ask your prenatal care professional about pregnancy-appropriate treatment. Do not assume every over-the-counter antacid is suitable or combine medicines without checking.
Pregnancy changes posture, balance, and the mechanical demands placed on muscles and joints.
As a result, the lower back, hips, and legs may feel uncomfortable during the night.
For mild positioning-related discomfort, try adjusting knee and abdominal support before replacing your entire sleeping setup.
A pillow between the knees can reduce unnecessary pelvic rotation during side sleeping. Gentle movement or pregnancy-appropriate stretching may also be comfortable for some people.
If you experience occasional leg cramps, changing position and gently stretching the affected muscle may help.
However, persistent or severe pain should be evaluated rather than assumed to be a normal consequence of pregnancy.
Sudden, pronounced swelling, redness, or pain in one leg requires prompt medical assessment because it may indicate a condition unrelated to ordinary muscle cramps.
Restless legs syndrome is different from an occasional muscle cramp.
It usually involves an uncomfortable urge to move the legs, often accompanied by sensations such as crawling, pulling, or tingling.
Symptoms typically become worse when resting, especially in the evening, and may improve temporarily with movement.
Restless legs syndrome can develop or worsen during pregnancy.
Iron status may be relevant, but symptoms cannot establish iron deficiency on their own.
If these sensations repeatedly prevent sleep, discuss them with your prenatal care professional. They may recommend evaluating iron status or other possible contributors.
Do not begin high-dose iron supplements or other treatments solely because you suspect restless legs syndrome. Pregnancy-related supplementation should follow individualized medical guidance.

Nasal congestion, changes in airway tissues, and other pregnancy-related physiological changes can contribute to snoring.
However, new or worsening loud snoring deserves attention when accompanied by:
These symptoms can be associated with obstructive sleep apnea, which may develop or become more noticeable during pregnancy.
Sleeping on your side may help with some positional breathing problems, but it does not diagnose or adequately treat sleep apnea.
Tell your prenatal care professional about concerning symptoms. They can decide whether a sleep evaluation is appropriate.
Pregnancy may involve worries about health, birth, family responsibilities, and future changes.
Some people also experience vivid dreams or nightmares.
A relaxing bedtime routine, a conversation with a trusted person, or a brief period of journaling may help reduce the feeling that you must solve every concern after getting into bed.
However, persistent anxiety, hopelessness, panic, or loss of interest in normal activities should not be dismissed as an inevitable part of pregnancy.
Perinatal mental health conditions are treatable, and your prenatal care team can help identify appropriate support.
| Main concern | Practical adjustment | When to seek advice |
|---|---|---|
| Frequent urination | Distribute hydration earlier and use the bathroom before bed. | Pain, burning, fever, or other possible infection symptoms. |
| Heartburn | Smaller meals, earlier eating, suitable elevation, or left-side sleeping. | Persistent, severe, or worsening symptoms. |
| Back or hip discomfort | Add pillow support and adjust pressure points. | Severe pain, neurological symptoms, or impaired daily functioning. |
| Restless legs | Review symptoms and discuss possible contributors with your prenatal team. | Repeated evening symptoms that interfere with sleep. |
| Snoring or gasping | Report symptoms and seek appropriate sleep-breathing evaluation. | Witnessed breathing pauses, gasping, or significant sleepiness. |
| Persistent insomnia | Review habits and ask about appropriate non-drug treatment. | Ongoing sleep difficulty affecting mood, health, or daily functioning. |
Several of these problems can occur together. If more than one symptom repeatedly interrupts sleep, discuss the overall pattern with your prenatal care professional rather than treating every symptom independently.
A consistent bedtime routine can make it easier to transition toward sleep, especially when your schedule and physical comfort change during pregnancy.
The goal is to reduce avoidable disruptions while allowing flexibility for fatigue, nausea, medical appointments, and other needs.
Most adults generally need approximately seven to nine hours of sleep, although individual requirements vary. Pregnancy does not create a single universal sleep target that applies to everyone.
Some pregnant people feel the need for additional rest, particularly during periods of substantial fatigue or fragmented nighttime sleep.
Try to maintain a consistent wake-up time and allow a realistic period for sleep.
For example, if you need to wake at 7:00 a.m., getting ready for bed early enough to allow an eight- or nine-hour sleep opportunity may be more practical than waiting until you are already exhausted.
Time in bed is not identical to time asleep, and a longer sleep opportunity does not guarantee uninterrupted sleep.
For more context on how sleep requirements change across life stages, see our guide to women's sleep needs.
Caffeine can interfere with sleep, particularly when consumed later in the day.
U.S. obstetric guidance generally advises keeping caffeine intake below 200 mg per day during pregnancy. Individual clinicians may recommend a different limit based on medical circumstances.
Remember that caffeine can come from coffee, tea, energy drinks, soft drinks, chocolate, and other sources.
For better nighttime comfort:
There is no need to follow a restrictive diet solely to improve sleep unless it is part of an individualized medical plan.
Regular physical activity can support general health and sleep routines during uncomplicated pregnancies.
For healthy pregnant people without contraindications, professional guidelines commonly recommend approximately 150 minutes of moderate-intensity aerobic activity per week.
Examples may include walking, swimming, or appropriately modified exercise.
However, the appropriate activity level depends on your health, fitness history, symptoms, and pregnancy-related medical considerations.
Discuss your activity plan with your obstetrician or other prenatal care professional, particularly if you have medical or obstetric complications.
Daylight exposure and reasonably consistent daily activities can also help support a regular sleep-wake schedule.
If exercise immediately before bed leaves you unusually alert, consider adjusting its timing rather than forcing the same routine every evening.
A practical evening routine might include:
This is an illustrative routine, not a medically established timetable.
A comfortably warm shower may be relaxing, but avoid overheating, very hot baths, and other heat exposure that is unsuitable during pregnancy.
If you wake to use the bathroom, do not worry about restarting the entire bedtime routine. Return to sleep as naturally as possible.
Naps can be helpful when pregnancy-related fatigue is significant or nighttime sleep has been interrupted.
If long or late naps make nighttime sleep more difficult, consider keeping them shorter or taking them earlier in the day.
However, there is no need to eliminate every daytime nap simply because you are pregnant.
Rest while awake may also be useful when you feel exhausted but cannot fall asleep.
If you experience excessive sleepiness that feels unusual, worsens, or substantially interferes with daily activities, discuss it with your healthcare professional rather than relying entirely on additional naps.
Occasional nighttime awakenings and changing sleep preferences are common during pregnancy.
However, pregnancy can also increase the likelihood of certain sleep disorders, and some symptoms that initially feel like ordinary discomfort may indicate a medical problem.
A useful distinction is whether the problem is manageable with routine adjustments, requires a scheduled medical assessment, or represents an urgent warning sign.
Insomnia involves difficulty falling asleep, staying asleep, or returning to sleep despite an adequate opportunity to rest.
When these difficulties become persistent and affect daytime functioning, it is reasonable to ask about evidence-based treatment.
Cognitive behavioral therapy for insomnia (CBT-I) is a structured treatment that addresses sleep-related behaviors and thoughts.
A randomized controlled trial involving pregnant participants found that CBT-I improved insomnia outcomes compared with a control intervention.
This supports considering clinician-guided, pregnancy-appropriate CBT-I rather than relying only on general sleep hygiene advice.
Because pregnancy changes physical comfort and sleep opportunity, treatment should be individualized. Do not independently begin aggressive sleep-restriction techniques intended for the general population.
Do not assume that an over-the-counter sleep medicine, herbal product, or supplement is appropriate during pregnancy simply because it is available without a prescription.
Some ingredients have limited pregnancy safety data, while others may cause side effects or interact with medications.
Discuss products such as melatonin, sedating antihistamines, herbal sleep remedies, and other sleep aids with your prenatal care professional before use.
Do not stop or change prescribed medication without medical guidance.
When sleep problems are caused by reflux, restless legs syndrome, sleep apnea, or another identifiable condition, treating the underlying issue may be more effective than taking a general sleep aid.
Seek immediate medical care if you experience serious or unusual symptoms such as:
These symptoms should not be managed by changing your sleeping position, taking a nap, or waiting for a better night's sleep.
For an immediate emergency, contact emergency medical services. For urgent pregnancy concerns, contact your obstetric care team or seek urgent assessment without delay.
If fetal movements are reduced or different from your baby's usual pattern, contact your prenatal team promptly rather than relying on an app or waiting until the following day.
Your personal medical circumstances may require additional precautions that are not covered by a general sleep guide.
Some people find it helpful to keep a simple record of sleep during pregnancy, particularly when their routine changes across trimesters.
A diary can help identify recurring problems such as frequent awakenings, changes in bedtime, or increased daytime sleepiness.
Consumer wearables can provide additional information, but their measurements require careful interpretation.
A sleep tracker may help estimate sleep duration, bedtime consistency, and overnight sleep patterns across multiple nights.
For example, a health tracking ring such as RingConn Gen 3 provides supported consumer wellness measurements and estimates, including sleep-related information and physiological trends.
These observations may help you notice changes in your usual routine.
However, pregnancy involves normal physiological changes that can affect heart rate, HRV, skin temperature, sleep, and activity.
A trend that differs from your pre-pregnancy baseline does not automatically indicate a complication or prove that something is wrong.
RingConn uses PPG-based technology for supported cardiovascular wellness measurements, including heart rate and HRV information.
These measurements describe aspects of the wearer's physiology. They are not direct measurements of fetal heart rate, fetal oxygenation, or fetal movement.
Similarly, RingConn skin temperature reflects changes in finger skin temperature rather than clinical core body temperature.
Consumer sleep-stage estimates are derived from sensors and algorithms; they are not equivalent to clinical polysomnography.
Neither a favorable sleep score nor an apparently normal HRV trend can confirm that a pregnancy is progressing normally.
A wearable also cannot rule out sleep apnea, preeclampsia, anemia, gestational diabetes, or another pregnancy-related medical condition.
If you have symptoms or concerns, rely on appropriate prenatal assessment rather than wearable data for reassurance.
Swelling can change finger size during pregnancy, particularly later in pregnancy.
If a ring becomes uncomfortable, difficult to remove, or begins restricting circulation, remove it promptly rather than continuing to wear it for uninterrupted tracking.
Do not force a tight ring over swollen tissue or ignore pain, numbness, or discoloration.
Sudden or pronounced swelling, particularly involving the face or hands and accompanied by headache or visual symptoms, can be a medical warning sign and requires urgent assessment.
Consistent sleep tracking is optional. It should never take priority over comfort, circulation, or medical care.
If you choose to record sleep during pregnancy, consider tracking a small number of useful observations:
Comparing several nights can sometimes provide more context than reacting to one unusual score.
However, there is no need to optimize every wearable measurement during pregnancy. Physiological data may change as pregnancy progresses, and consumer algorithms are not designed to replace pregnancy-specific medical evaluation.
Bottom line: Better sleep during pregnancy usually comes from responding to your current symptoms, finding comfortable and appropriate sleeping positions, and maintaining a flexible routine. During later pregnancy, start sleep on either side, use pillows where they help, and seek professional guidance for persistent or concerning symptoms. Prioritize maternal and fetal health over achieving a perfect sleep score.
Yes. Both left-side and right-side sleeping can be appropriate during pregnancy. The left side may be more comfortable for some people, particularly when nighttime reflux is present, but you do not need to remain exclusively on the left side unless your prenatal clinician recommends it for a specific reason. During later pregnancy, beginning sleep on either side is generally recommended over starting the night flat on your back.
If you wake on your back, do not panic. Simply turn onto your left or right side and return to sleep. During later pregnancy, recommendations generally focus on choosing a side position when falling asleep. It is normal to change positions during the night, and there is no need to stay awake monitoring every movement. Discuss specific positioning concerns with your prenatal care professional.
As pregnancy advances, side sleeping becomes more important because the growing uterus can place pressure on major blood vessels when you lie flat. Some public-health guidance recommends going to sleep on either side after 28 weeks, based partly on observational research concerning late-pregnancy outcomes. Studies covering earlier stages have produced more reassuring findings, so the evidence should not be treated as identical across all trimesters. Follow individual advice from your prenatal clinician.
There is no single pregnancy-specific number of sleeping hours that guarantees health or comfort. Most adults generally need about seven to nine hours, although individual requirements vary. Pregnancy may increase fatigue or interrupt nighttime rest, making additional sleep opportunity or daytime rest helpful for some people. If you are persistently exhausted despite adequate sleep opportunity, discuss your symptoms with a healthcare professional to assess for possible contributing conditions.
Nighttime awakenings can result from several pregnancy-related changes, including frequent urination, heartburn, back or hip discomfort, leg cramps, fetal movement, anxiety, and difficulty maintaining a comfortable position. The dominant cause may change between trimesters. Identifying which symptom wakes you most often can help guide practical adjustments. Persistent insomnia, breathing disturbances, or other unusual symptoms deserve medical assessment rather than being dismissed as normal pregnancy discomfort.
Do not start melatonin, prescription sleeping pills, over-the-counter sleep aids, or herbal sleep products without discussing them with your prenatal care professional. Pregnancy safety information varies by ingredient, dosage, and individual medical circumstances. Some products lack sufficient safety evidence, while others may be appropriate only after clinical assessment. For persistent insomnia, ask about pregnancy-appropriate cognitive behavioral therapy for insomnia and treatment of any underlying symptoms.
Snoring can become more noticeable during pregnancy because of changes in the upper airway and other physiological factors. However, loud or worsening snoring accompanied by breathing pauses, gasping, choking, or significant daytime sleepiness may indicate obstructive sleep apnea. Tell your prenatal care professional about these symptoms so they can determine whether testing is appropriate. A consumer wearable cannot diagnose or exclude sleep apnea, and position changes alone may not provide adequate treatment.
