Also called: trouble sleeping in pregnancy
At 37 weeks pregnant, experiencing insomnia often feels like a complex interplay of physical discomforts and a mind racing with anticipation, making restful sleep particularly elusive. This late stage of pregnancy brings unique challenges that can disrupt sleep, from increased frequency of needing to use the restroom (nocturia) to heightened anxiety about the upcoming birth, and even restless legs. Many parents-to-be find themselves awake for hours, despite feeling utterly exhausted. It's a common experience, with sleep disturbance affecting a significant majority of pregnancies by this third trimester.
Understanding what's happening in your body can bring a sense of calm. As a trained full spectrum doula, I often hear from clients around 37 weeks about the compounding effect of these physical and emotional shifts on their sleep patterns. While your body is preparing for birth, your mind might be processing a lot, leading to a cycle of wakefulness. It's helpful to remember that you're not alone in this; research consistently shows that sleep challenges are a prevalent part of late pregnancy. Just as your body adapts to changes like increased vaginal discharge at 15 weeks pregnant or the later stages, managing sleep requires a gentle, informed approach.
One important consideration for sleep during this time is your sleeping position. Evidence suggests that after 20 weeks of pregnancy, sleeping on your left side is preferred. A 2019 meta-analysis found an association between falling asleep on your back in the third trimester and an increased risk. This isn't meant to cause alarm, but rather to offer an evidence-based option for making informed decisions about your sleep habits. Many find that strategically placed pillows, such as body pillows or wedge pillows, can provide the physical support needed to comfortably maintain a side-sleeping position throughout the night. These tools can make a significant difference in reducing physical discomfort, which is often a primary driver of wakefulness at 37 weeks.
Beyond physical comfort, addressing any underlying anxiety or feelings of overwhelm can be a powerful step toward improving sleep. While I provide practical wellness guidance and education, your care provider is your best resource for specific medical concerns. What I often tell clients is that sometimes, sleep interventions alone aren't enough if the mind is consistently racing. Exploring gentle practices to support your nervous system, or having conversations about your birth preferences, can sometimes ease the mental load. Just as you might notice changes like increased vaginal discharge at 18 weeks pregnant and seek understanding, approaching sleep with curiosity about its various contributing factors can be beneficial. For some, cognitive behavioral therapy for insomnia (CBT-I) is an evidence-based treatment option that focuses on changing sleep-related thoughts and behaviors. This approach can be particularly helpful when persistent worry or anxiety is impacting your ability to rest.
Remember, every pregnancy experience is unique, and you get to decide what feels right for you. Whether it's adjusting your sleep environment, exploring relaxation techniques, or discussing your concerns with your provider, there are options to help navigate this period. Thinking about how your body adapts throughout pregnancy, from increased vaginal discharge at 20 weeks pregnant to the current physical demands, can help frame these late-pregnancy changes as part of a natural process, even when they bring discomfort.
