Helping Clients Understand the Impact of Labor Hormones (Plus a Teaching Activity)

Early in my doula career, I remember working with a family who knew they wanted a doula to support them through their pregnancy and birth. This particular mother had a previous birth that she felt didn’t go well and felt like she was pressured into unnecessary interventions. She was nervous about going back to the same hospital and the possibility of her past doctor being “on call” again. Her plan for this birth was going to be to labor at home for as long as possible and then head to the hospital for the birth when contractions were strong and close together.

It was a peaceful spring morning and I joined this mother as her contractions were coming regularly and gaining in intensity. She and her husband made the decision that it was time to head to the hospital. It was easy to see that her contractions were only a few minutes apart and very strong. Shortly after arriving at the hospital, her contractions went from 2-3 minutes apart to 6+ minutes apart. I couldn’t believe what I was seeing! It was like her labor was slowing down and going into reverse! Eventually, she was able to get settled into her comfortable routine and contractions picked up, but it took a lot longer than I expected!

Hormones play a big part in our lives, and especially during labor and birth. Doulas can help our clients learn more about their bodies and how labor hormones will impact their labor process. While there are many hormones that are involved with pregnancy and labor, I like to talk about four specifically.


Oxytocin is responsible for labor contractions and is often referred to as the “love” hormone. Oxytocin can cause feelings of calmness and euphoria, even in labor. It plays a major part in helping labor progress smoothly. This hormone is also crucial for helping new parents’ bond with their baby!


Melatonin is released during times of calm and typically in the dark. (Have you ever wondered why labor often starts in the middle of the night? Melatonin is at work!) Melatonin boosts oxytocin.


I love reminding families that our bodies are designed with ways of coping with intensity of contractions by releasing endorphins. These are powerful natural pain relievers and stress relievers!


Adrenaline is the one hormone we want to limit during the first stage of labor. This causes the body to enter into a “fight or flight” stress response state which is not ideal in labor. It can increase heart rates and breathing rates. Adrenaline can be useful for the second stage of labor, pushing.

Teaching Activity

Talking about the impact of hormones in labor is a topic I cover during all prenatal appointments and childbirth classes I teach. One activity I have partners do is a personalized t-chart with the intent of thinking about promoting labor progress and limiting adrenaline. This can then be used to create a birth plan or shared with other people on their birth team. Here is a sample list from a recent client:

Oxytocin, Endorphins, Melatonin Adrenaline
Low Lighting at home and hospital

Flameless tea lights

Wearing my own clothing

Listening to my playlist

Bouncing on birth ball

Laboring at home

Having Buster (dog) close by

Spending time in the birth tub

Slow dancing together

Being about to move in labor and not confined to a bed

Hot tea, snacks, and water bottle in basket on counter

Bright Lights

Lots of medical people in the room watching

Family in the waiting room

Partner being on phone/social media

Getting the IV

Being told to stay in bed

Not being a part of decisions


After our clients make this list, we can talk about our role as doulas in helping with those things that are going to promote labor progress. Maybe we can get the tea lights set up and help get the tub ready at home or birth location. Maybe we could encourage using a birth ball at the birth location instead of being in the bed.

This type of activity also gives support partners lots of ideas of what their role in labor could be too. They can help keep the lighting low and act as a “bouncer” to keep family and visitors out of the laboring space. They can do the slow dancing and be a part of labor positions. They can ask medical staff to explain what they would like to do and allow time for discussions.

Many families have expressed that this simple activity helped them understand more about how amazing their bodies are and also relieved that their body has built-in ways to help them through labor.
