understanding the role of oxytocin

When preparing for birth, it can easy to focus on everything we need to do. Choose the right midwife, take childbirth classes, think about our birth preferences, gather supplies for postpartum, and spend months getting everything ready for the baby.

Those things are important, but I've come to believe there's another kind of preparation that's just as valuable.

Preparing your heart.

Pregnancy is a unique season because you're not only growing a baby—you are also being shaped into a mother. The thoughts you dwell on, the environment you create around yourself, the people you spend time with, and the ways you care for your mind and spirit all matter. God designed us as a whole. Our physical, emotional, and spiritual lives aren't separate; they influence one another every single day. Together they make up our wellbeing.

One of my favorite examples of this is a hormone called oxytocin.

what is oxytocin?

Oxytocin is commonly known as the love hormone or the bonding hormone, but those names barely scratch the surface of everything it does.

Oxytocin is produced in the hypothalamus and released by the pituitary gland. Throughout our lives, it's involved in connection, trust, affection, and relationships. It's released when we hug someone we love, kiss our spouse, laugh with a close friend, eat a piece of chocolate, cuddle our children, or experience genuine feelings of safety and belonging.

Have you ever noticed how your whole body seems to relax after a long hug? Or how holding a newborn against brings an overwhelming sense of peace?

That's oxytocin at work.

It's one of the ways God designed our bodies to experience connection.

Rather than keeping us in a constant state of stress or alertness, oxytocin helps calm our nervous system. It encourages relaxation, lowers stress, and reminds our bodies that we are safe.

And during pregnancy, its role becomes even more remarkable.

creating oxytocin in pregnancy

One of the most incredible things about pregnancy is that your body spends months preparing for labor before contractions ever begin.

As your baby grows, your uterus is quietly changing too.

Throughout pregnancy, the muscle of the uterus develops more and more oxytocin receptors. You can think of these receptors like tiny doorways or docking stations that allow the uterus to experience the oxytocin when it's released. The more you create during pregnancy, the more that can be received during labor.

By the end of pregnancy, there are dramatically more receptors than there were in the beginning. Your body has been preparing for this moment all along.

When labor begins and oxytocin is released in increasing amounts, those receptors help create the rhythmic, coordinated contractions that gently draw your baby lower and lower. Once your baby is low enough and your cervix is out of the way, your body triggers an even bigger rush of oxytocin to begin pushing, until they're finally in your arms.

Your body isn't suddenly trying to figure birth out when labor starts. It's been preparing for months. Every week of pregnancy has been part of that preparation and your body is full of wisdom and divine design.

reducing stress during pregnancy

One of the beautiful roles of oxytocin is that it helps quiet the body's stress response. As oxytocin is released, it promotes feelings of calm, safety, trust, and connection while helping to lower the effects of stress hormones like cortisol. In many ways, oxytocin and stress work against one another. The more our bodies settle into a state of peace, the more easily oxytocin can do its work. Likewise, when we're carrying constant fear, anxiety, or chronic stress, it can become more difficult for oxytocin to be released as effectively.

This doesn't mean you need a stress-free pregnancy—because let's be honest, that's simply not realistic. Pregnancy comes with unknowns, and every mother will have moments of worry. Instead, it's an invitation to intentionally create moments of peace throughout your day. Taking a walk, sharing a hug with your spouse, laughing with a friend, receiving a massage, listening to worship music, spending time in prayer, reading Scripture, or simply sitting quietly with the Lord are all ways to support both your emotional well-being and your body's incredible design.

oxytocin as nature's pain relief

One of the most incredible things about oxytocin is that it doesn't just help labor progress—it also helps your body cope with labor.

As oxytocin is released during labor, it stimulates the production of endorphins, the body's natural pain-relieving chemicals. Endorphins are often compared to the body's own "natural opioids" because they help reduce the perception of pain while also creating feelings of calm and well-being.

This is one of the reasons labor is so beautifully designed. As contractions become stronger through oxytocin, your body is also releasing endorphins to help you work through those contractions. It's a remarkable balance. Rather than simply producing stronger contractions without support, God designed your body to respond by creating natural pain relief at the same time.

While oxytocin produces strong contractions, it simultaneously gives the feeling of love and pain relief. How beautiful.

This doesn't mean labor won't be intense. Birth is hard work, and every woman's experience is unique. But it does remind us that our bodies weren't designed to work against us. They were designed to work with us.

When a laboring woman feels safe, supported, and free to move through labor in her own rhythm, oxytocin and endorphins can continue working together. That's one reason why creating a peaceful birth environment—with trusted support, dim lighting, gentle encouragement, and freedom from unnecessary stress—can make such a difference in how labor is experienced.

It's another beautiful reminder that God didn't simply create birth to accomplish a task. He thoughtfully designed a process that helps a mother bring her baby into the world while also equipping her body with the hormones she needs to support, comfort, and sustain her along the way.

the role of oxytocin after birth

And once your baby is born, oxytocin's work isn't finished. When laboring unmedicated the hormones of labor go without disruption allowing for a mother to experience the highest dose of oxytocin once she sees her baby.

The same hormone that helped guide your baby into the world now helps your uterus continue contracting to stop and slow bleeding. It supports milk let-down when breastfeeding begins. It strengthens the bond between mother and baby in those first precious hours after birth. 

birth works best when you feel safe, unobserved, and warm

One thing we know about oxytocin is that it thrives when a woman feels safe.

When we feel cared for, supported, encouraged, and protected, our bodies are generally more able to release oxytocin naturally. On the other hand, when we're overwhelmed by fear or experiencing intense stress, our bodies produce more stress hormones like adrenaline and cortisol.

Those hormones have an important purpose. If you're in danger, they're exactly what you want your body to produce.

But labor isn't meant to feel like running from danger.

Birth asks the body to soften, surrender, and work with its own rhythms.

That's one reason so many women find comfort in dim lighting, familiar faces, gentle touch, quiet encouragement, and being surrounded by people they trust.

Safety isn't only physical.

It's emotional, too.

where faith enters the picture

This is one of the reasons I think spending time with God during pregnancy matters so much. Not because prayer guarantees a certain kind of birth. Not because worship somehow eliminates every fear. And certainly not because women who experience difficult births didn't have enough faith.

What I am saying is that God's presence has a way of settling our hearts. When we pray, we're reminded that we don't have to carry every fear by ourselves. When we read Scripture, we're filling our minds with truth instead of every scary story we've heard online. When we worship, our attention shifts from everything we can't control to the One who is always faithful. When we practice gratitude, we begin noticing God's goodness instead of dwelling only on our worries.

None of these things replace good birth education or quality care. They simply remind us that we are not walking into birth alone and there is something deeply peaceful about that.

how connection with God nourishes oxytocin

One of the reasons I love learning about birth physiology is because it continually points me back to the Creator. 

The more I study the body, the more I'm amazed by how intentionally everything works together. Pregnancy isn't just about growing a baby—it's about preparing a mother. Month after month, your body is making tiny changes that often go unnoticed until labor begins. Oxytocin receptors increase, your uterus prepares to respond, and your body quietly gets ready for the work of birth.

When I think about oxytocin being called the love hormone, I can't help but think about the God who is love Himself.

trusting the design

A hormone that strengthens contractions also helps you bond with your baby. The same hormone that brings your baby into your arms also helps your uterus recover after birth and supports breastfeeding in those first precious days. It's thoughtful, purposeful, and beautifully interconnected.

While we can't control every part of our birth story, we can prepare in ways that support the way our bodies were created to work. Nourishing ourselves well, surrounding ourselves with supportive people, creating a peaceful birth environment, learning about the physiology of birth, and spending time in God's presence are all simple ways we can care for both our bodies and our hearts.

So as you prepare to meet your baby, don't just think about your labor prep or your birth plan. Think about how you're caring for your mind and spirit, too. Make space for prayer. Turn on worship music while you fold tiny clothes. Journal about things that you need to work through emotionally. Pause to thank God for the life growing inside you. Take a walk and talk with Him about your hopes and your fears.

These moments may seem small, but they gently cultivate peace throughout pregnancy. And while no hormone or habit can promise a certain birth experience, there is something deeply comforting about knowing that the God who designed your body also walks with you through every contraction, every unknown, and every first moment of meeting your baby.

What a beautiful gift that is.
