Sleeping during the third trimester of pregnancy can be challenging due to the increased belly size, the baby’s movements, and pregnancy-related discomforts like heartburn and back pain. The best sleeping position is on your left side, as it enhances blood flow and nutrients to your placenta and baby. Additionally, using pillows for support, avoiding back sleeping, and establishing a relaxing bedtime routine can help improve sleep quality during this period. Now, let’s delve deeper into these strategies to facilitate more restful sleep in the final months of pregnancy.
Finding Comfortable Positions for Sleep
During the third trimester, it’s essential to optimize your sleeping position for both your comfort and the health of your developing baby. The recommended position is the SOS (sleep on side), and more specifically, lying on your left side. This position improves circulation, aiding in delivering nutrients to your baby, and helps manage swelling by easing the workload on your kidneys. To enhance your comfort, consider these tips:
Use Supportive Pillows
Pregnancy pillows or regular cushions can be used to support your growing belly and can help alleviate stress on your back and hips. Placing a pillow between the knees can align your hips to your pelvic area, reducing discomfort. Some women find relief by also tucking a small, rolled towel under their side to support the abdomen.
Elevate Your Upper Body
If heartburn is an issue, try elevating your upper body with pillows. This can prevent stomach acids from flowing back up into the esophagus, which is a common cause of discomfort for many pregnant women.
Avoiding Back Sleeping
Although back sleeping may have been comfortable in the early stages of pregnancy, it can cause problems in the third trimester. This position can lead to backaches and impair blood flow as the uterus presses on the vena cava, potentially reducing circulation to your heart and baby. If you find yourself waking up on your back, don’t panic—simply roll back onto your side.
Creating a Relaxing Bedtime Routine
Developing a bedtime routine can significantly improve your chances of getting a good night’s sleep. Here are some techniques to consider:
Mindful Relaxation
Practices such as meditation, deep breathing exercises, or progressive muscle relaxation can help calm your busy mind and relieve stress before bedtime. Even a few minutes of these activities can have a positive impact on your sleep.
Avoid Stimulants
Caffeine and sugar can both interfere with your ability to fall asleep, so it’s best to avoid them in the late afternoon and evening. Pay attention to hidden sources of caffeine, such as chocolate or certain medications.
Lights Out
Bright lights can inhibit the production of melatonin, your sleep-inducing hormone. Dim the lights in your home as bedtime approaches and consider using a nightlight in the bathroom to avoid harsh lighting during nighttime trips.
Battling Pregnancy-Related Issues That Interrupt Sleep
There are several pregnancy-related issues that can disturb sleep during the third trimester. Here’s what you can do to manage these challenges:
Leg Cramps and Restless Legs Syndrome (RLS)
Leg cramps and RLS can be particularly bothersome at night. Gentle stretches before bed can help, as can ensuring that you’re getting enough magnesium and calcium in your diet. Talk to your healthcare provider before taking any supplements.
Frequent Urination
Minimize fluid intake in the hours leading up to bedtime, but make sure you still drink plenty of water during the day to stay hydrated. If you do need to get up, use as little light as possible to help you return to sleep more easily.
Anxiety and Stress
Worrying about your baby’s arrival and the changes it will bring is natural, but it can lead to insomnia. Consider discussing your feelings with your partner, a friend, or a healthcare professional. Writing in a journal or engaging in mild yoga or stretching exercises before bed can also help ease stress.
Nutrition and Exercise’s Role in Better Sleep
Proper nutrition and regular exercise can significantly impact the quality of your sleep.
Healthful Eating Habits
Eating a balanced diet with a focus on small, frequent meals can prevent a full stomach at bedtime, reducing the chance of heartburn and discomfort. Choose foods rich in protein, fiber, and complex carbohydrates and limit spicy, acidic, or greasy foods, particularly close to bedtime.

Unless your healthcare professional advises otherwise, mild to moderate exercise can promote better sleep. Prenatal yoga or a daily walk can contribute to fatigue in a healthy way, making it easier to fall asleep. However, avoid vigorous exercise close to bedtime as it can have the opposite effect.
Adapting Your Sleep Environment
A tranquil and comfortable sleep environment also plays a crucial role in how well you sleep.
Keep It Cool
A slightly cooler temperature in your bedroom can aid in better sleep. The ideal temperature for sleep is around 65 degrees Fahrenheit (18 degrees Celsius).
Invest in a Good Mattress and Bedding
Ensure that your mattress supports your body correctly, and use pillows effectively to make your bed as comfortable as possible. Soft, breathable bedding can keep you at an optimal temperature throughout the night.
Reduce Noise and Light
Consider using earplugs if noise is an issue and blackout curtains to block out light. White noise machines can also create a soothing background to help drown out disruptive sounds.
When to Seek Medical Advice
If these strategies are not providing relief, or if you’re experiencing significant discomfort or anxiety about sleep, consult your healthcare provider. They can offer guidance on safe medication options, provide referrals for sleep specialists, or address other underlying issues that may be affecting your sleep.
Finishing Thoughts
Sleeping well during the third trimester can be a challenging ordeal, but with the right strategies and support, it’s possible to find comfort and rest. Prioritize your sleep environment, adopt a gentle exercise routine, and be mindful of your dietary choices. Above all, don’t hesitate to seek advice and support from your healthcare provider. Following these tips can lead to improved sleep, helping you to remain energized and healthy in preparation for the arrival of your little one. Remember that every woman’s pregnancy experience is unique, and what works for one person may differ for another. Listen to your body and adjust your sleep strategies accordingly for the best results.
