Labour hormones

Labour hormones

Labour hormones

By Lucy Hercus, Mamaway

Labor is called labour for a reason, it’s tough work and there’s no getting around it. However, if someone claimed that you could have a comfortable and swift labour, you’d want to hear about it, right?

The first place to start, is to understand some of the crazy, wicked, Yoda-smart labour hormones that your clever little system is capable of producing!

Oxytocin (the love drug)

If you’re pregnant, you’ve experienced this guy before, Mr Oxytocin, the love drug (cue: Barry White). He visits us during love-making and saunters back to pay us a visit, when we’re in labour.

Oxytocin contributes to the stimulation and ripening of the cervix, required for dilation during labour.

Oxytocin levels rise at the on-set of labour, causing regular contractions. It’s these contractions that become stronger and more frequent, that eventually result in your baby being born. This wonder drug then makes us feel close to our babies and draws us to bond with them.

Beta-endorphins (natural pain killer)

Claimed to be as powerful as pethidine, you want these on your side.

Beta-endorphins (cue: Bob Marley) help to relieve pain and contribute to the ‘out of body’ feelings some women experience when they labour without drugs. These hormones also prime a woman’s body for the bonding between herself and baby post-birth.

Adrenalin (fight or flight hormone)

Also called catecholamines (cat-e-kol-a-meens), adrenalin is the ‘fight or flight’ hormone (cue: ACDC). This hormone is perfect if you encounter a zombie and you need to leg-it, fast! But, adrenalin production is not what you want for a comfortable, swift labour.

Although needed at the end of labour – for the big push – for the first stage of labour, adrenalin is plain bad news and the production of it contributes to labour being long and painful. So, how do we keep adrenalin ‘at the gate’, until it’s needed?

When I’m supporting a birthing woman, I look to create a ‘nest’ for her. No, I’m not collecting twigs and shoelaces… I’m talking about ensuring all her needs are met and that she feels both secure and calm. This will help negate the production of adrenalin.

Now that we know something about the hormones produced in labour, how do we use them to make labour as calm and comfortable as possible?

Adopt rhythmic breathing

Breathe in through your nose and out through your mouth. Your breath in will occur involuntarily but you might need to be reminded to release this breath as there’s a tendency to breathe in, clench and fight the contraction.

Bring some comforts from home

I was at a birth once where mum and dad brought in a lamp, floor rug and window dressings. I’m not kidding. No, I’m talking about your pillow, a nice photo and your dressing gown. If you bring your entire home contents, the midwives will think you’re off your nut.

Essential oils

When asked what birth smells like… I say vaginas, because it just does. If this increases your vulnerability (and adrenalin production!), pop in some oil and diffuser sticks. Birth is naturally odorous so if you don’t like the idea of that – go hell-for-leather with the oils. A day spa is a tops place to birth in.

Bring a small array of creature comforts from home and the right hormones will thank you.

Cool cloths and warm socks

Your face will get hot and your feet, cold. Use a cool wipe on your face and don some socks so you can remain on-task.

A well-educated and supportive partner / doula

They’ll need to be clued-up on the below strategies and super-attentive to your needs.

Plenty of electrolyte-rich fluids

Once you’re dehydrated, you wont hydrate easily with water. Bring several flavours of these. Dehydration can stall labour. They’ll need to be clued-up on the below strategies and super-attentive to your needs.

Diversion from adrenalin through sense of touch:

Heat packs

Heat reduces pain by up to 40%. Lie it across those two cute dimples on your lower back (sacrum), during a contraction. Take off after the contraction ends. The heat packs should be very warm but obviously not hot enough to burn! (chemically-activated heat packs are best, with their heat-limitation).

The bath

Don’t get in too early and have plenty of fluids whilst you’re in there. A bath is a glorious place to labour, and birth in! (speak with your OB/midwife prior, if you hope for a water birth).


Usually firm, strong, circular motions (during the contractions) at the sacrum work well. Talk with your support person about what you think you might like. If you don’t like massage ordinarily, you sure wont like it when you’re labouring.

Diversion from adrenalin through sense of hearing:

Encourage vocalisation

Maintain a rhythm. The breath out can be as noisy as you like, as long as you’re releasing all that tension.


The birthing instinct takes place in the primal part of our brain. Choose instrumental (only) music, to negate engaging the ‘newer’, language centres of the brain. Keep it primal.

Shaker or stress balls

Totally weird, right? hear me out because this is really a thing…Some women bang a shaker rhythmically against their leg – they’re not mimicking Lola, the Showgirl from The Copacabana, rather it’s a percussive rhythm that can just help you get in the zone. Likewise, with the stress balls – used to tap against the wall. Match your volume to the intensity of your contractions.

Diversion from adrenalin through sense of smell:


Put a few drops of 100% pure essential oil on a cloth and inhale with breaths through contractions. It’s pretty intense. Lavender’s good, but if it reminds you too much of your granny’s drawers, go for citrus.

Diversion from adrenalin through sense of sight:

Visual focus

You’ve got to be strongly visual for this one to work well. I’ve seen laminated peaceful photos, inspiring words, bible verses, mandalas, a small bunch of buds and flowers. The lot. Whatever brings you to a place of visual focus. Hopefully something that inspires you to do what you’ve come to do – get that kid outta there.

Diversion from adrenalin through movement:

General movement produces endorphins in labour. There are loads of positions to try and your movement to get to each of these will benefit your hormone production. Move into positions that feel comfortable through contractions.

Hospital resources

Most will carry their own bean-bags, mats and birth balls. Keep gravity working for you, the perfect hormones being released, and experiment away
