Pregnancy's Influence on Sleep: How You Can Battle It & Understanding Changes in Sleep Patterns | Sleepcosee

Pregnancy's Influence on Sleep

It is no surprise that pregnancy impacts your sleep. When you are pregnant, your entire bio-mechanism changes.

Regardless of the trimester, you’re currently in, pregnancy would have a profound effect on your sleep regime.

We can easily blame it on the hormonal changes which take place during pregnancy but there are a lot of other factors to consider.

The sleep issues you experience might vary based on how far you are into your pregnancy. This article explains why it happens and what you can do to get the rest you deserve.

Understanding the Impact of Hormones on Pregnancy Sleep Patterns

Impact of Hormones on Pregnancy Sleep Patterns

Hormonal changes during pregnancy impact your sleep, mood, metabolism, and physical appearance. Inevitably, any sudden hormonal change will impact your pattern of sleep.

Progesterone, during pregnancy, relaxes your muscles. It could also end up stimulating a frequent sensation to urinate which disrupts sleep. It keeps you from going into REM Sleep.

Estrogen on the other hand could act as a vasodilator that stretches and enlarges your blood vessels. It can result in nasal congestions, heartburns, and swelling of limbs. All of which directly affects your sleep.

Prolactin that’s secreted during pregnancy pushes you into the ideal slow-wave sleep.

And finally, oxytocin is a major contributor to contractions. Its levels are most likely to spike during nights which may also lead to a higher chance of labour.


What Can You Expect In Each Trimester?

What Can You Expect In Each Trimester?

Pregnancy is a remarkable journey that unfolds in three distinct phases, commonly known as trimesters. Each trimester brings its own set of changes and challenges, both for your body and your sleep patterns. Let's delve into what you can anticipate during each trimester.

First Trimester: Early Changes and Adaptations The first trimester encompasses the initial three months of pregnancy. During this phase, your body embarks on a whirlwind of transformations. Hormonal shifts and physical adjustments are in full swing, impacting your sleep in unique ways. You might notice increased fatigue, leading to longer nighttime sleep and even more frequent daytime naps. However, as the first trimester progresses, sleep disruptions can make their appearance. Frequent awakenings during the night and reduced slow-wave sleep might become familiar companions, altering your sleep experience.

Second Trimester: A Period of Relative Tranquility As you transition into the second trimester, spanning from weeks 13 to 28, you might find a temporary respite from some of the sleep challenges of the first trimester. Many expectant mothers report feeling better overall during this period. Sleep might become more restful as you experience fewer awakenings during the night after falling asleep. Yet, sleep quality could ebb and flow, and by the end of the second trimester, you may find yourself grappling with disruptions once again. It's essential to acknowledge that sleep experiences vary widely from one woman to another.

Third Trimester: Preparing for the Arrival The third trimester is marked by the countdown to delivery, spanning from the end of the 7th month until the baby's arrival. While excitement builds, sleep can become more challenging. Achieving a deep sleep might feel elusive, and you might oscillate between light sleep stages. Frequent daytime naps can impact your overall sleep efficiency. The pressure on your bladder and the sheer physical size of your baby can make finding a comfortable sleep position a task in itself.

Enhancing Your Sleep Quality During Pregnancy: Effective Strategies and Tips

How Can You Improve Your Sleep During Pregnancy

Embarking on the journey of pregnancy introduces significant adjustments to your sleep patterns. The intricate dance of hormonal shifts and bodily changes orchestrates a series of transformations in how you experience rest. Throughout the trimesters, your sleep routine evolves, and understanding these shifts is key to managing your sleep comfort.

Pregnancy impacts your sleep but there are certain sleep positions that can help you ease out.

If you can sense discomfort in your lower body and especially around your hips, try slipping a Cosee Cloud Ball Fiber Pillow or one of Sleepcosee's Jacquard Cushions in between your legs while you sleep. This will help you relieve the amniotic fluid pressure between your uterine walls.

You can also ensure optimal blood flow from the inferior vena cava (IVC) by sleeping on your left. This is considered the “ideal” sleep position during pregnancy.


1. How does pregnancy impact sleep patterns? Pregnancy triggers hormonal shifts that can disrupt sleep patterns. Hormones like progesterone and estrogen affect muscle relaxation, frequent urination, and nasal congestion, leading to sleep disturbances.

2. Do sleep patterns change throughout pregnancy? Yes, sleep patterns evolve through trimesters. The first trimester may bring increased sleep and daytime naps, while the second trimester offers better sleep quality. However, the third trimester introduces challenges like discomfort and frequent awakenings.

3. What are effective solutions to battle sleep issues during pregnancy? Optimize sleep positions by using pillows for support. Sleeping on your left side enhances blood flow. Relaxation techniques, warm baths, and prenatal yoga can promote better sleep. Consulting a healthcare professional for advice is also recommended.

4. Can emotional changes affect sleep during pregnancy? Yes, the anticipation of parenthood and emotional changes can contribute to sleepless nights. Anxiety, excitement, and mood swings may impact sleep quality.

5. How can understanding these changes lead to better sleep during pregnancy? Awareness of hormonal and physical changes empowers expectant mothers to adapt their sleep routines. Implementing recommended sleep positions, relaxation methods, and seeking professional guidance can significantly improve sleep comfort throughout pregnancy.


In the early stages of pregnancy, sleepless nights can be attributed to a combination of factors, including hormonal fluctuations, physical discomfort, and heightened anxiety.

The surge in hormones, such as progesterone and estrogen, can lead to disruptions in sleep patterns. 

Emotional changes and the anticipation of impending parenthood can also contribute to restless nights. By understanding these factors and implementing relaxation techniques, comfortable sleep during early pregnancy can be achieved for a healthier and more restful journey.
