20 TENS Unit Benefits: Time To Invest In A Machine?

Using a TENS unit can provide relief from chronic and acute pain by stimulating nerves and producing endorphins. Other benefits include it being non-invasive and portable for on-demand treatment, with few reported side effects.

TENS Unit Benefits

You may have heard a lot about TENS units or perhaps you’ve just discovered the therapy and want to know more.

Chances are what you really want to know is whether the therapy actually works?

With more and more research supporting the effectiveness of the treatment, the simple answer is, yes it does!

Take a look below at 20 proven TENS unit benefits:

Benefit 1: Drug-free Natural Pain Relief

1: Drug-free Natural Pain Relief

One of the major benefits of transcutaneous electrical nerve stimulation is that it’s a natural and effective form of pain relief with little or no known side effects.

A systematic review of research in 2014 found that overwhelmingly TENS was proven to treat both acute and chronic pain.

It’s often chosen as a treatment by those who are looking for a drug-free option to avoid the known negative side effects of taking pain medication.

For example, a longitudinal study published in 2015 looked at how the side effects of medication can influence a patient’s daily activities.

It demonstrated the alarming impact on a patient’s abilities to achieve simple tasks.

Findings led researchers to recommend that physicians need to balance the impact of the side effects of the medication with the relief from pain before prescribing.

Benefit 2: Produces Endorphins

2: Produces Endorphins

Endorphins are our body’s natural painkillers.

They are essentially hormones that exist in the brain, that are released when the body experiences any sort of stress.

Endorphins act as transmitters, creating a feeling of ecstasy and wellbeing which in turn helps to reduce pain signals.

Natural ways to release endorphins include music, sex, chocolate and group exercise.

The UK’s NHS also recognizes that TENS helps! Electrical impulses are thought to stimulate the production of endorphins.

This short film from neurotech explains how the process works:

Research shows how important endorphins are in pain management, which is one of the reasons why TENS is thought to be such an effective form of relief.

Benefit 3: Decreases Pain Signals to the Brain

3: Decreases Pain Signals to the Brain

Studies have proven that a TENS device can help to decrease or block pain signals traveling to the brain, providing users with the relief they crave.

When you look at the science behind how a TENS unit actually works, you can see how the machine stimulates the nerves. It’s this stimulation that is thought to keep the pain signals from reaching the brain.

If you want a machine for pain relief, then the iReliev Wireless TENS + EMS Muscle Stimulator is worth a look.

After testing the device for many months, we found it so simple to use, with the wireless pods meaning you can easily treat anywhere on your body.

In fact, in our roundup of the best TENS units on the market, we gave this device the number one spot.

Plus with this machine, you get all the advantages of electrical muscle stimulation (EMS).

It offers different benefits to TENS therapy, and is ideal if you want to build muscle.

As well as helping to manage pain, it is also thought that over time a TENS machine can actually retrain the nerves, even for those suffering from nerve damage.

Chiropractors feel that the treatment, if conducted over an extended period of time, can change the behavior of the nerve and stop it from sending pain signals to the brain.

Benefit 5: Reduces Inflammation

5: Reduces Inflammation

Though research is still limited, studies have shown that TENS is powerful when it comes to reducing inflammation.

Researchers can’t confirm exactly how it manages to achieve this, however a study on pro inflammatory cytokines did find it to be effective.

Benefit 6: Control over Your Treatment

6: Control over Your Treatment

A TENS unit provides you with complete control over your treatment, unlike pain medications where it isn’t always possible or feasible to simply increase or reduce the dose if it isn’t working.

Depending which device you choose, you’re provided with a range of different intensity settings and modes to target the pain, it’s simply a case of finding the right TENS machine for your needs.

  • It’s important to note however, when shopping for a TENS unit, that the number of intensity settings doesn’t relate to the power of the machine.

When users speak about chronic daily pain, they often speak of the frustration they feel in terms of having no control over their condition.

User feedback suggests that TENS offers that control, helping with the psychological impacts of day to day pain management.

Benefit 7: Effective for Different Conditions

7: Effective for Different Conditions

TENS therapy has been shown through research to be powerful for a wide range of different conditions. In particular for back pain, as well as the many different forms of arthritis.

Lesser known uses for a TENS machine include help for those suffering from urinary incontinence, as well as mental health conditions such as depression and anxiety.

A study published in the Journal of Mid-Life Health looked at women suffering from idiopathic pelvic pain.

Results showed that TENS can be an accessible intervention, with significant improvements seen in pain scores. In fact, two patients reported being completely pain free following TENS therapy.

Benefit 8: Few or No Side Effects

8: Few or No Side Effects

One of the many reasons that the NHS suggests TENS for managing pain is because they are found to have little or no side effects.

Side effects from overuse have been reported, so you should always follow the manufacturer guidance.

Plus you should always speak to a medical professional before starting treatment so they can advise on correct usage.

PRO TIP – Don’t forget to check for latex-free pads if you have a latex allergy!

Benefit 9: Effective Complementary Therapy

9: Effective Complementary Therapy

The nature of a TENS unit (non-invasive, little or no known side effects) makes it an excellent complementary therapy to more intensive treatments.

Recent research has shown that it can help cancer patients going through chemotherapy, providing patients with some level of control over their pain.

Benefit 10: Suitable for Chronic and Acute Pain

10: Suitable for Chronic and Acute Pain

TENS is amazingly found to be good for both chronic and acute pain.
