Pregnancy is often described as a time of joy and anticipation, but for many expectant mothers, it can also bring an unexpected challenge: insomnia. Struggling to fall asleep, waking up repeatedly during the night, or rising far earlier than intended can leave pregnant women feeling exhausted. According to the NHS, sleep disturbances affect the majority of women at some point during their pregnancy, particularly in the later stages.
This guide explores why insomnia is so common during pregnancy, what factors contribute to it, and what can be done to improve sleep during this critical time.
What Is Pregnancy Insomnia?
Pregnancy insomnia refers to persistent difficulty in falling or staying asleep during pregnancy. It is not considered a separate medical condition but rather a symptom experienced as part of the physiological and emotional changes that occur.
Although occasional sleeplessness is normal, pregnancy insomnia tends to be more frequent and intense, often leading to a cycle of fatigue, stress, and further sleep disruption.
How Common Is Insomnia During Pregnancy?
Research indicates that sleep disturbances affect 66% to 97% of pregnant women at some point (Mindell et al., 2015).
The likelihood of insomnia increases as pregnancy progresses, with the third trimester being the most challenging period.
While some women experience sleep problems early in the first trimester due to hormonal fluctuations, others only begin to struggle as physical discomfort, frequent urination, and anxiety set in later on.
What Causes Insomnia During Pregnancy?
Several factors contribute to pregnancy-related insomnia, and they often interact in complex ways:
Hormonal Changes
Increased levels of progesterone, while vital for maintaining pregnancy, can also cause excessive daytime sleepiness and disrupt normal sleep architecture. Fluctuations in other hormones like estrogen and cortisol can also affect sleep quality.
Physical Discomfort
Growing abdominal size, back pain, breast tenderness, and restless legs syndrome are common physical challenges that make finding a comfortable sleeping position difficult.
Frequent Urination
The kidneys work harder during pregnancy, and the enlarging uterus places pressure on the bladder. This often leads to multiple nighttime trips to the bathroom, especially in the third trimester.
Anxiety and Stress
Concerns about the baby's health, labour, childbirth, and the transition to parenthood can all fuel nighttime anxiety, making it hard to relax and fall asleep.
Heartburn and Gastrointestinal Issues
Pregnancy hormones relax the valve between the stomach and oesophagus, making heartburn (acid reflux) more common. Lying down can worsen these symptoms, disrupting sleep.
Sleep Apnoea
Weight gain and increased tissue in the upper airway during pregnancy can cause or worsen obstructive sleep apnoea, leading to fragmented sleep and frequent awakenings. Untreated sleep apnoea can increase risks for gestational hypertension and preeclampsia (Lungeanu-Juravle L et. Al)
When Does Insomnia Usually Start During Pregnancy?
Insomnia can begin at any point, but many women first notice issues around the end of the first trimester or into the second. Sleep tends to become even more fragmented in the third trimester, when physical discomfort and bladder pressure are at their peak.
Effects of Insomnia on Pregnancy Health
Persistent insomnia during pregnancy is more than just frustrating—it can have real health implications. Studies have associated poor sleep with:
Increased risk of gestational diabetes (Facco et al., 2017)
Higher rates of preeclampsia
Longer and more difficult labours
Higher likelihood of postpartum depression (Okun et al., 2011)
It is important to address insomnia both for maternal health and for the health of the developing baby.
Natural Ways to Manage Insomnia During Pregnancy
While sleep medications are generally avoided during pregnancy unless absolutely necessary, several safe and natural strategies can help manage insomnia.
Create a Pregnancy-Safe Sleep Routine
Having a consistent bedtime routine can signal to the body that it is time to sleep. This might include a warm (not hot) bath, gentle stretching, meditation, or listening to calming music.
Optimise Sleep Environment
Investing in a supportive pregnancy pillow can help alleviate discomfort. Keeping the room cool, dark, and quiet can also promote better sleep.
Mindful Eating and Drinking
Avoid heavy meals close to bedtime, and reduce fluid intake in the evening to minimise nighttime bathroom trips. Limiting caffeine—found in tea, coffee, and chocolate—is also essential. Current NHS guidance suggests pregnant women limit caffeine intake to 200mg per day (NHS).
Practice Relaxation Techniques
Breathing exercises, mindfulness meditation, and progressive muscle relaxation have all been shown to help reduce stress and improve sleep.
Left-Side Sleeping
Sleeping on the left side improves blood flow to the baby and reduces pressure on the liver and kidneys. Using pillows to support the bump and knees can make this position more comfortable.
According to Dave Gibson, Osteopath and Sleep Coach:
"One benefit of optimal kidney function is that it improves tissue draining and potentially helps to reduce swelling of areas such as the legs and ankles, which can often accompany the later stages of pregnancy"
Light Exercise
Gentle activities such as walking, prenatal yoga, or swimming can help promote better nighttime sleep. However, vigorous exercise too close to bedtime may be counterproductive.
When to See a Healthcare Professional
While occasional sleeplessness is normal, it is advisable to speak to a GP or midwife if:
Insomnia becomes chronic
Sleep deprivation leads to severe daytime fatigue
Symptoms of depression or severe anxiety emerge
Snoring becomes loud and frequent (a potential sign of sleep apnoea)
In some cases, professional support such as cognitive behavioural therapy for insomnia (CBT-I) can be very effective and safe during pregnancy.
Can Herbal Remedies Help Pregnancy Insomnia?
Some women turn to herbal remedies to ease sleep problems, but caution is required during pregnancy.
Valerian root, chamomile tea, and lavender are sometimes used for insomnia, but their safety during pregnancy is not firmly established. According to the NHS, herbal supplements are not regulated as strictly as medicines, and some may pose risks.
Always consult a midwife, GP, or pharmacist before using any herbal remedy or supplement during pregnancy.
The Role of Vitamins and Sleep Aids During Pregnancy
Certain vitamins and minerals, such as magnesium, may support better sleep by aiding muscle relaxation and nervous system function. However, supplementation should be discussed with a healthcare provider to ensure safety and appropriate dosing.
Over-the-counter sleep aids, including antihistamines like diphenhydramine, are sometimes considered, but only under medical advice. Melatonin supplements, while widely used for insomnia, are not routinely recommended during pregnancy due to insufficient safety data.
Tips for Partners and Family
Supporting an expectant mother struggling with insomnia can make a huge difference. Partners and family members can:
Share household responsibilities to reduce stress
Encourage healthy sleep habits
Be understanding about mood changes related to poor sleep
Attend prenatal appointments when possible to stay informed
Empathy and practical support can go a long way toward alleviating the emotional burden of pregnancy insomnia.
Preparing for Sleep Changes After Birth
It is worth noting that sleep disruption does not necessarily end after pregnancy. Newborn care often involves multiple nighttime awakenings. Building a solid foundation of healthy sleep habits during pregnancy can ease the transition into early parenthood.
Final Thoughts: Navigating Insomnia During Pregnancy
Pregnancy is a time of profound physical and emotional change, and some sleep disturbance is almost inevitable. Understanding the causes of pregnancy insomnia and taking proactive steps to manage it can dramatically improve quality of life.
If insomnia becomes overwhelming, seeking medical advice is crucial. Help is available, and addressing sleep issues early can contribute to a healthier, happier pregnancy experience.

Frequently Asked Questions About Insomnia and Pregnancy
Is insomnia a sign of pregnancy?
Insomnia can sometimes be an early sign of pregnancy due to hormonal changes, although it is not considered a definitive symptom on its own. Many women experience disrupted sleep during the first trimester.
How can I sleep better while pregnant?
Maintaining a consistent bedtime routine, using pregnancy pillows for support, practicing relaxation techniques, and limiting caffeine can all contribute to better sleep during pregnancy. Speaking to a healthcare provider if sleep problems persist is also important.
Is it normal to wake up every hour during pregnancy?
Frequent awakenings are very common during pregnancy, particularly in the third trimester. Factors such as bladder pressure, heartburn, and discomfort often interrupt sleep.
Can pregnancy insomnia harm the baby?
Occasional sleep disruption is unlikely to harm the baby. However, chronic insomnia can increase the risk of complications such as gestational diabetes and preeclampsia. Managing insomnia effectively supports both maternal and fetal health.
Are there safe sleep aids for pregnancy insomnia?
Most over-the-counter and prescription sleep aids are not recommended during pregnancy unless prescribed by a doctor. Non-medical treatments like cognitive behavioural therapy for insomnia (CBT-I) and relaxation techniques are generally considered safer.
What positions are best for sleeping during pregnancy?
Sleeping on the left side is recommended as it improves blood flow to the placenta and helps reduce pressure on internal organs. Using pillows for extra support can enhance comfort.
