What Is a TENS Machine — and Should You Hire One for Labour?
Thinking about your birth toolkit and wondering if a TENS machine is worth it?
If you're in the final stretch of pregnancy, chances are you've seen people mention TENS machines for labour. Maybe you're not quite sure what they actually do (or if they're just another thing to hire and forget about). So let’s break it down in plain terms — no fluff, just the stuff you need to know.
What even is a TENS machine?
TENS stands for Transcutaneous Electrical Nerve Stimulation (a mouthful, we know). It's a little handheld device that sends gentle electrical pulses through pads you place on your lower back. These pulses are thought to block pain signals and help your body release endorphins — aka your natural painkillers.
In birth, TENS is often used in early labour or during contractions to take the edge off — especially when you’re trying to stay home as long as possible or aiming for a drug-free birth.
Why mums (and midwives) love it:
💛 It gives you something to do during contractions — a bit of focus and control
💛 It’s totally drug-free and safe to use alongside other pain relief methods
💛 You can start using it early at home — way before heading into hospital
💛 It’s portable, non-invasive, and doesn’t interfere with your movement
When should I use it?
TENS works best when you start using it early in labour — before things get super intense. That’s because the endorphin-building effect is more helpful the earlier you begin. So if you’re hiring one, plan to have it ready and in your birth bag by 37 weeks.
Should I buy or hire a TENS machine?
TENS machines aren’t just for birth — some people use them for physio or recovery — but if you’re only wanting it for labour, hiring is way more affordable. Ours is midwife-backed, super simple to use, and comes with everything you need, including fresh pads, batteries, and a case.
(And yep — we ship NZ-wide, and recommend booking from 37 weeks.)
Final thoughts?
No pain relief option is one-size-fits-all, but a TENS machine is a low-risk, high-reward tool to have in your birth toolkit. Whether you’re aiming for an unmedicated birth or just want all the options, this little buzzy device might just become your new best friend.
