Sleep Hygiene and Pregnancy: How to Rest Better While Expecting
Pregnancy is a miraculous journey, characterised by profound physiological and emotional changes. However, for many expectant mothers, it is also synonymous with exhaustion. Whether it is the overwhelming fatigue of the first trimester or the physical discomfort of the third, getting a good night’s sleep can feel like an elusive goal.
Quality sleep is essential for both your wellbeing and the development of your baby. It is during sleep that your body repairs itself, regulates hormones, and supports your immune system. Yet, statistics suggest that a vast majority of pregnant women experience disrupted sleep patterns.
By prioritising sleep hygiene—a variety of different practices and habits that are necessary to have good nighttime sleep quality and full daytime alertness—you can significantly improve your rest. This guide explores authoritative, evidence-based strategies to help you navigate sleep challenges throughout your pregnancy.
Understanding Why Sleep Changes During Pregnancy
Before diving into solutions, it is helpful to understand the biology behind your fatigue. From the moment of conception, your body undergoes a massive hormonal overhaul.
The primary driver of early pregnancy fatigue is progesterone. This hormone acts as a natural sedative. While it is vital for maintaining the pregnancy, it can leave you feeling drained even after a full night’s rest. Furthermore, your metabolic rate increases, and your body produces more blood to support the growing foetus, which consumes a significant amount of energy.
You can read more about early pregnancy symptoms to understand how these hormonal shifts affect your daily energy levels.
Sleep Challenges by Trimester
Sleep disturbances tend to evolve as your pregnancy progresses. Understanding what to expect can help you prepare and adapt your routine accordingly.
The First Trimester
In the initial months, the sudden surge in progesterone is the main culprit. You may also find your sleep disrupted by a frequent need to urinate, as your growing uterus presses against your bladder. Nausea, commonly known as morning sickness, can also strike at night, making it difficult to settle.
The Second Trimester
Often referred to as the “honeymoon phase,” the second trimester typically brings renewed energy. However, this is also a time when many women report vivid, strange, or disturbing dreams. This is often due to interrupted sleep cycles or anxiety about the impending life changes. For more on emotional health, explore our guide on managing prenatal anxiety.
The Third Trimester
This is generally the most challenging period for sleep. Your baby has grown significantly, making it difficult to find a comfortable position. Issues such as heartburn, leg cramps, and shortness of breath are common. According to the NHS, it is normal to feel tired during this stage as your body prepares for labour.
What is Sleep Hygiene?
Sleep hygiene refers to the behavioural and environmental factors that precede sleep and may interfere with it. It is not about cleanliness in the traditional sense, but rather about “cleaning up” your habits to promote better rest. For pregnant women, good sleep hygiene is not just about feeling rested; it is about optimising health outcomes for mother and baby.
Research published in PubMed indicates that poor sleep quality in pregnancy can be linked to complications such as longer labour durations and higher rates of Caesarean sections, making these habits crucial.
Essential Sleep Hygiene Strategies for Pregnancy
Implementing a robust sleep hygiene routine can mitigate many common pregnancy complaints. Below are the most effective, science-backed strategies.
1. Establish a Consistent Routine
Your body’s internal clock, or circadian rhythm, thrives on consistency. Aim to go to bed and wake up at the same time every day, even on weekends. This regularity helps programme your brain to recognise when it is time to wind down.
Create a relaxing pre-sleep ritual. This might include:
- Reading a book (avoiding overly stimulating thrillers).
- Practising gentle pregnancy yoga stretches.
- Listening to calming music or a guided meditation.
2. Optimise Your Bedroom Environment
Your bedroom should be a sanctuary for sleep. During pregnancy, your body temperature runs slightly higher than usual due to increased blood flow. Therefore, keeping the room cool—ideally between 16°C and 18°C—is vital.
Ensure the room is dark and quiet. Consider using blackout curtains or an eye mask. If you live in a noisy area, a white noise machine can be helpful. For more tips on setting up your home, see our article on preparing your home for baby.
3. Manage Your Fluid Intake
Hydration is essential, but timing is everything. Drink plenty of water throughout the day to support your increased blood volume and amniotic fluid levels. However, try to taper off your intake two hours before bed to reduce the frequency of nighttime bathroom trips.
4. Mindful Eating Habits
Heartburn and indigestion are major sleep thieves, especially in the third trimester. To minimise this:
- Avoid spicy, acidic, or fried foods in the evening.
- Eat smaller, more frequent meals rather than three large ones.
- Finish eating at least three hours before lying down.

The Importance of Sleep Position
As your bump grows, your sleeping position becomes a matter of medical safety, not just comfort.
The safest position to go to sleep is on your side, specifically the left side. This position optimises blood flow to the placenta and foetus. Sleeping on your back in the third trimester presses on major blood vessels, which can reduce blood flow to the baby and make you feel faint.
The charity Tommy’s runs a significant campaign regarding this, highlighting that side-sleeping can halve the risk of stillbirth in late pregnancy. Do not panic if you wake up on your back; simply roll over onto your side.
Using Pillows for Support
Invest in a good pregnancy pillow, or use regular pillows to support your body. Placing a pillow between your knees can align your hips and reduce lower back pain. Another pillow under your bump can support the weight of the baby. For recommendations, read our review of top-rated pregnancy pillows.
Addressing Common Sleep Disruptions
Even with good hygiene, specific physical symptoms can keep you awake. Here is how to handle them.
Restless Legs Syndrome (RLS)
Many pregnant women experience an uncontrollable urge to move their legs, often accompanied by a tingling sensation. This can be linked to low iron or folate levels. If you suspect this, consult your midwife or GP. Gentle massage and warm baths can also provide relief.
Leg Cramps
Sudden, painful cramps in the calf muscles are common at night. Stretching your calf by flexing your foot upwards (toes toward the knee) can stop a cramp in its tracks. Ensuring you have adequate magnesium and calcium intake is also beneficial. Learn more about supplements during pregnancy here.
Anxiety and Insomnia
Racing thoughts about labour, parenthood, or finances can lead to insomnia. Cognitive Behavioural Therapy for Insomnia (CBT-I) techniques can be very effective. This involves challenging negative thoughts about sleep. Resources from Mind can offer excellent support for mental health during this period.
Diet, Exercise, and Sleep Quality
What you do during the day dictates how you sleep at night.
Caffeine and Sugar
Caffeine is a stimulant that stays in your system for hours. The Royal College of Obstetricians and Gynaecologists (RCOG) recommends limiting caffeine intake to 200mg a day, but if you are sleep-deprived, consider cutting it out completely after midday.
Physical Activity
Regular exercise can help you tire your body out in a healthy way and reduce stress. However, avoid vigorous exercise right before bed, as the adrenaline may keep you awake. Gentle activities like swimming or walking are ideal. See our guide on safe exercises for the third trimester.
When to Seek Professional Help
While fatigue is normal, certain sleep issues require medical attention. You should speak to your healthcare provider if:
- You snore loudly or gasp for air: This could be a sign of Obstructive Sleep Apnoea (OSA), which is linked to high blood pressure and pre-eclampsia.
- You have severe insomnia: If you are consistently unable to function during the day due to lack of sleep.
- You experience restless legs: As mentioned, this may require blood tests to check iron levels.
The National Institute for Health and Care Excellence (NICE) provides guidelines on managing clinical sleep disorders during pregnancy that your doctor will follow.
Natural Sleep Aids: What is Safe?
Many women ask about herbal teas or supplements. While chamomile tea is generally considered safe and relaxing, you should always check with your midwife before taking any herbal remedies or over-the-counter sleep aids, including melatonin. For a list of safe options, consult our article on herbal teas and pregnancy safety.
Instead of supplements, try natural relaxation techniques. The Lullaby Trust emphasises the importance of a smoke-free environment for both maternal sleep health and the safety of the baby after birth.
Preparing for Postpartum Sleep
Developing good sleep hygiene now is excellent practice for when the baby arrives. While a newborn’s sleep schedule is unpredictable, the ability to nap effectively and prioritise rest will serve you well. You might want to read about newborn sleep patterns to manage your expectations for the fourth trimester.
The Bottom Line
Sleep hygiene during pregnancy is about more than just comfort; it is a vital component of your prenatal care. By making small adjustments—such as sleeping on your side, optimising your bedroom temperature, and establishing a calming routine—you can improve the quality of your rest significantly.
Remember to be kind to yourself. If you have a bad night, try to rest during the day. Your body is doing the incredible work of growing a new life, and it deserves all the rest it can get. For further reading on health guidelines, the Department of Health and Social Care offers various resources for expectant mothers.
If you are struggling to cope with fatigue, never hesitate to reach out to your midwife or GP. Prioritising your sleep is prioritising your baby.
