Labor Hormones in Under 10 Minutes

“Note: this page is about how to TEACH this concept to expectant parents. If you’re an expectant parent looking for info on labor hormones, their effect on labor pain, and what your partner can do to help you have a shorter and less painful labor, click here.

In my childbirth classes, and with doula clients, I want them to understand that our emotions, and the support we receive, absolutely affect labor on a physiological basis, by influencing our hormones. The big message is that fear and anxiety slow labor down and make it more painful. Support and feeling safe make labor faster and easier. I have simplified the complex details into a simple stick figure drawing that takes 5-10 minutes.

Before I talk about my teaching method, let’s start with a basic summary* of hormones:

Hormone What Does It Do What doesn’t help What does help
Oxytocin Causes labor contractions that dilate cervix Anxiety, bright lights, feeling observed, feeling judgedPitocin – if have synthetic oxytocin, make less hormonal oxytocin To increase oxytocin: Skin-to-skin contact.
Nipple stimulation, making love.To increase endorphins: social contact and support from loved ones.To increase oxytocin and endorphins and to reduce adrenaline: create an environment where we feel private, safe, not judged, loved, respected, protected, free to move about.(So, partners, if you remember nothing else about labor support, remember that if she feels safe, loved and protected her labor will be faster, and less painful)
Endorphins Relieve pain, reduce stress (cause euphoria and feelings of dependency) Stress, lack of supportNarcotics (if you have an external opiate, your body will start producing less internal opiate… even after the narcotics wear off, you’ll have less endorphins)
Catecholamines (adrenaline, etc.) In early / active labor: slow labor down(Imagine a rabbit in a field. If it doesn’t feel safe, it wants to keep baby inside to protect it)In pushing stage: Make you and baby alert and ready for birth, give you energy to push quickly.
(If the rabbit is about to have a baby, and something frightens it, it wants to get the baby out as quickly as possible so it can pick it up and run with it.)
Stress / anxiety / fearLack of control

Feeling trapped

Hunger, cold

 

So, in class how do I convey these ideas in just a few minutes, so it’s easy to understand and to remember?

First, I say: “In labor, our emotions and our environment effect our hormones. Our hormones have a huge effect on labor. Let’s look at a couple scenarios for labor.” [I draw two stick figures on the board.] “This one is awash in stress hormones which will make labor longer and more painful. Let’s label it adrenaline. This one is under the influence of oxytocin and endorphins. These help the laboring person shift into an altered state where labor pain is milder (less intense and less unpleasant) and also help labor progress more quickly.” [Add labels to drawings, add sad face and smiley face.]

Then I say “So, you are all probably familiar with adrenaline. What do we call it? Yes, the fight or flight hormone. This is the idea that if an individual ran into a tiger in the woods, they would choose either to fight it or to run away. Do you know what we call oxytocin? Many call it “collect and protect” or “tend and befriend.” If a tiger is coming into our village, we gather everyone together, because we are safest together.” [I add these labels to my drawing.]  (I sometimes throw in the tidbit here that men who are not dads are more likely to release adrenaline during stressful situations; women and dads are more likely to release oxytocin – it’s the “gather the babies and protect them” response.)

“So, what effect do these hormones have?”

“With adrenaline, all your muscles tighten. All your energy goes to your limbs in case you need to fight or run away. So, oxytocin production drops and labor slows down. (It’s hard for your cervix to open when you feel scared…)  You are also more sensitive to pain – this is useful if you’re at risk of injury – your body tells you what to move away from. But, in labor it’s not helpful – it just means labor hurts more!”

“With oxytocin and endorphins all your muscles relax. Energy is sent to the uterus and oxytocin increases. (Oxytocin is often called the love hormone, because it increases when we feel loved, and its peak levels are when we orgasm, when we birth, and when we breastfeed. It’s all about making babies, birthing babies, and feeding babies.) We also get an increased endorphin flow, which makes us less sensitive to pain, can cause euphoria, and can cause feelings of love and dependency in us… “I love you man….””

Birth is Simple Physics

Birth Positions

We know this or rather do we know this? Movement plays an important role during labor and birth.

Through out the history of womankind, not just the last 75 years, women have changed positions as they felt the need during childbirth. Laying in bed to give birth was not a common practice.

When you consider the physics of giving birth laying in bed for hours is counter productive to the design of a woman’s body. In a supine position or laying down a woman’s pelvic outlet closes and decreases the space for a baby to descend. Laying down in bed can also exacerbate and make any discomfort worse.

Moving through childbirth is a great way to cope with the intensity of contractions and help labor to progress.

 

 

 

 

 

This poster from Childbirth Graphics is a great teaching tool. It is also available as a tear sheet.

Birth PositionsIt is important when woman are pregnant to have them along with their support person try as many different positions as possible in order to connect with their bodies and discover what makes them comfortable. Having this knowledge and connection to their bodies will be of benefit during birth. It will give them the confidence to know what is right and intuitively they will work with their bodies to progress labor.

Directed Pushing

“What to Know:

  • Research shows that routine directed pushing, breath holding, and limiting pushing during labor is not beneficial, and that prolonged breath holding may reduce fetal oxygenation.
  • The World Health Organization (WHO) recommends not directing laboring women to hold their breath or consciously sustain pushing.
  • The American College of Nurse Midwives (ACNM) recommends that a laboring woman’s body direct any pushing.
  • Directed pushing may help you if you’ve had an epidural and don’t feel the urge to push.”

Limp and Loose in Labor: 8 Practical Tips

8 Practical Labor Tips “The muscle at the center of labor is the uterus and the cervix is the passageway between the uterus and the vagina.  I like to think of the cervix like doors that have to open up before the baby can exit. The role of each contraction is to gently open the cervix or open up the doors.”
