Your Guide to Using TENS Units for Labor
Hey there, mamas! 🌟 If you’re prepping for birth and scouring every corner of the internet for ways to make labor a little (or a lot) more comfortable, you’ve probably stumbled upon something called a TENS unit. But… What exactly is it? Electricity seems kind of scary…Can it actually help during labor?
I will answer all your questions! (Have more? just ask!)
What is a TENS Unit?
TENS stands for Transcutaneous Electrical Nerve Stimulation. Essentially, it’s a small, portable device that sends low-voltage electrical currents to your skin via sticky pads (electrodes) that you place on your body. The idea is that these gentle electrical pulses can help manage pain by:
Blocking pain signals from reaching your brain. (Gate theory of pain)
Boosting the release of endorphins, your body's natural painkillers. (Endogenous Opioid theory of pain)
How Does it Work During Labor?
When you’re in labor, placing the TENS unit pads on your lower back can help alleviate discomfort, especially during those early stages (and sometimes during back labor can make all the difference). Here’s why so many moms give it a thumbs up:
Non-invasive and drug-free: No meds, no needles, just some gentle zaps and taps to help you manage your sensations.
You’re in control: You can adjust the intensity and frequency of the electrical pulses, turning it up or down depending on what feels good for you.
Portable and easy to use: Clip it onto your waistband or pop it in a pocket. You can move around freely, which is a big win during labor.
When Should You Start Using It?
Most mamas find it helpful to start using the TENS unit during the early stages of labor, when contractions are beginning but not too intense yet. It’s all about getting ahead of the pain curve—catching it before it becomes overwhelming.
I always recommend to take it out of its package, charge it if need be, and TRY it before labor! Just like with the yoga and meditations in Beyond Birth… I want you practicing all of this before you actually need it so that it is natural, reassuring, and accessible to you.
Are There Any Downsides?
While TENS units can be a game-changer for some, they’re not for everyone. Here are a few things to keep in mind:
Not a miracle worker: It will not completely eliminate the pain, but it can take the edge off.
Placement is key: You’ll need to place the electrodes correctly for the best effect, which might take a little trial and error. (Hence my point above!)
Not suitable for all stages: The TENS unit will need to be set aside:
Once you’re in the thick of active labor (it might be annoying)
If you’re considering a water birth (don’t get in the water with an electrical machine attached to you please!!),
Pro Tips for Using a TENS Unit During Labor
Practice before the big day: Like I said! Get familiar with your TENS unit ahead of time so you know how to put it on and adjust the settings to your liking. (There are no “correct” settings… just ones that make you feel good)
Ask your birth partner for help: They can help place the electrodes and adjust the settings as needed. (Practice with them before!!)
Combine with other comfort measures: Think of the TENS unit as part of your labor toolkit. Use it alongside your breathing techniques, movement, the comb, and all the other comfort measures you’ve learned from me for the best results.
Where Do I Find a TENS Machine?
Many hospitals have them on hand… but having worked in a hospital where they were hard to come by, I would recommend buying your own! Here are my favorites.
This one is pretty straightforward
This one has all the bells and whistles (it has TENS and EMS and and and… so if you know what you’re doing this one is fun. But if you don’t - just get a TENS machine and keep it to the TENS settings!)
This one is specifically for period cramps. It definitely has the pink tax.
Final Thoughts
TENS units can be a fantastic tool for managing labor pain, offering a safe, drug-free option to help you stay in control and as comfortable as possible. While it might not be the perfect fit for everyone, it’s definitely worth considering as part of your birth plan.
