What’s a TENS unit? 

A transcutaneous electrical nerve stimulation (TENS) unit sends electrical impulses through the skin, targeting painful areas in the body. 

The unit is battery operated so it’s great for on-the-go pain relief.

One of the biggest benefits of using a TENS unit is that it controls pain signals by releasing endorphins. Endorphins are hormones secreted within the brain and throughout the nervous system that activate the body’s opiate receptors, causing an analgesic or pain relieving effect.

This causes an effect similar to taking an opioid or narcotic medication.

Thus, you can get immediate relief after using the unit just once, making it a very useful tool for pain relief.

Here’s what you need to know about finding the best TENS unit:

Easing your pain becomes possible by choosing one of the best TENS units on the market.

TENS Unit FAQ

Three Different TENS Units

How does a TENS unit work?

A TENS unit has electrodes with adhesive pads that attach to the person’s skin. 

When it’s turned on, these pads send electrical impulses into the person’s skin that enter the nervous system. 

When these impulses reach the nervous system, they inhibit pain signals going through the spinal cord to the brain, thus decreasing the nervous system’s ability to send pain signals. 

This is why you get pain relief from TENS units.

There’s an added benefit to those electrical impulses, though. They boost the body’s production of endorphins, which are natural pain relievers. 

This is why TENS units are used for a variety of health conditions, including neck and back pain, arthritis, and chronic muscle pain.

There are different frequencies that can be chosen on the TENS unit so you can adjust the number of electrical pulses per second. 

Low frequency has pulses of one to 20 cycles per second and are used to alleviate chronic pain. 

High frequency pulses, on the other hand, have a range of 80 to 120 cycles per second that makes them more efficient for treating acute pain.

The great thing about TENS units is that they help you take better control of your pain. 

They’re small and easy to carry around, especially when they contain a belt clip. 

This enables you to get pain relief wherever you are without having to get back home first.

How often should you use a TENS unit?

Woman Relaxing With TENS Unit

While it might be tempting to want to use a TENS unit almost constantly if you find that it gives you relief from your pain and discomfort, this should be avoided. 

If used too much, you can actually become too used to the pain relief and “numb” to its benefits.

A study published in the journal Future Medicine found that people who use a TENS unit with the same intensity and frequency every day can become tolerant to its effects, which means that they don’t get the same relief from pain that they used to.

So, to prevent that from happening to you, it’s a good idea to switch between low frequency and high frequency within and between sessions.

When it comes to how often you can use a TENS unit, the good news is that you can generally use it daily if you need pain relief. Of course you should always consult with your treating physician on how often and where to use your TENs unit.

Sessions should generally last for about half an hour, but again consult your physician.

It’s good to give your skin a break from the electrode pads at least every half an hour to avoid skin irritation.

If you’ve been using your TENS unit and it’s no longer giving you the relief you want, then that’s a sign you should take a break for a day or so to give your nerves the chance to settle down. 

In the future, stick to the maximum session duration of 30 minutes.

What are the side effects of using a TENS unit?

Scratching Skin

As with any therapy or medication, you have to consider the possible side effects of using a TENS unit. 

While TENS units are safe for most people to use, they do create sensations of buzzing, prickling, and tingling, which could be uncomfortable for some people. 

In addition, the adhesive pads that stick to the skin can cause an allergic reaction and skin irritation. 

People who experience this side effect can use hypoallergenic pads as an alternative so that they can still use a TENS unit.

TENS units should be used with some precautions in mind. 

You should never put the electrodes on the front of your neck as this can cause neck spasms as well as lower your blood pressure, as Medical News Today reports.

People who have certain health conditions such as epilepsy, heart conditions, and anyone who has a pacemaker or any metal implant should avoid using TENS units.

In addition, pregnant women should only use a TENS units under the treatment of their obstetrician and should never apply pads to their abdomen or pelvic areas.

Can you sleep with a TENS machine on?

Using your TENS unit at night while asleep may sound very appealing if your pain gets worse at night and interrupts your rest. 

However, using a TENS unit while you sleep is not a good idea for various reasons. It is generally not safe to use your unit for more than thirty minutes at a time.

Additionally the buzzing of the unit could interfere with your sleep and the electrodes could irritate your skin from prolonged use.

You might even turn over in your sleep and end up with the TENS unit in an awkward or unsafe position, and you don’t want to risk that. 

Finally, one of the electrode patches might come off, which could mean that you’re not even getting the benefits from the unit.

You should always use your TENS unit when you are awake so you can be aware of sensations and changes in the machine. 

If you’re at risk of falling asleep with your TENS unit on, it’s a good idea to purchase a TENS unit that has an automatic shut-off feature, such as the Healthmate Forever TENS unit featured in our TENS unit reviews.

Does a TENS unit help with inflammation?

Increased blood flow to tissues can be very beneficial for muscle strains and pain because it brings more oxygen and nutrients to painful areas of the body which promotes healing. 

Research published in the Canadian Journal of Plastic Surgery found that TENS units change skin temperature and actually increase local blood flow.

The same research also suggests that TENS units boost wound healing and repair tendons. These units cause calcitonin gene-related peptides to be released leading to increased blood flow and faster tissue repair.

TENS unit that has different massage modes, such as the kneading massage that’s available in the Kedsum rechargeable TENS unit can improve blood flow even further.

Conclusion

If you suffer from pain and want some temporary relief without reaching for painkillers or you’re worried about how many pain pills you’ve been taking each day, a TENS unit can be just what you need to get relief from your discomfort. 

A TENS unit works with different frequencies to release electric impulses into the body. 

This obstructs pain signals and increases the body’s production of endorphin. Endorphins don’t just make you feel better but also have an anti-inflammatory effect to bring down swelling.

Whether you’re suffering from muscular pain after an injury or you’re battling with a chronic condition, a TENS unit is a reasonable treatment to try.

Because many of these models are small enough to carry around you can often use them whenever you feel the first sensations of pain.

Best of all, a TENS unit gives you greater control over your pain. Instead of having to book a session at a massage or physical therapist, you can give yourself therapy whenever you need it.

With the many extra perks available in TENS units these days, you might just feel like you’re having a session at a spa.
