Waterproof TENS Machine: The Need To Know

A TENS machine kit with necessary information

Living with chronic pain can be incredibly challenging. It can affect every aspect of the life of a person. Traditional pain relief methods may not always be sufficient. Thus, it leads many to seek alternative options. Transcutaneous Electrical Nerve Stimulation, or TENS machines, have gained popularity as a non-invasive and drug-free way to manage pain. However, people should know that there are no waterproof TENS machines. They use electric components, and water can damage the device.

Pregnant women can also use TENS for their labour pains as long as they consult their doctors first. Some women opt for water birth. They can still use TENS, but they can only do so before showering or submerging in the pool. Otherwise, it can cause issues like the loss of adhesion of the pads. To learn more, the following sections will present the answer to whether TENS and water can go together, how TENS works, and its usage guidelines.

Waterproof TENS Machine: Can TENS Be Used in Water?

Unfortunately, people cannot use TENS in water. The market does not have waterproof TENS machines currently. This is because the device uses electric currents to reduce pain. Moreover, placing the electrode pads on wet skin or surfaces can cause them to lose their stickiness. This can lead to the ineffectiveness of TENS. It can also make them buy more pads.

Some individuals may want to utilise TENS while showering. However, since it is not water resistant, they can only place the pads before or after getting out of the shower. Likewise, women who are opting to do water birth can do the therapy before or after the process.

Furthermore, exposing the unit to water can cause it to short circuit and create a safety hazard. It can damage the machine in the long run. As a result, it can cause further harm to the patients. Additionally, TENS devices are usually sealed with a protective coating that prevents water ingress. This makes them unsuitable for usage in water or wet environments.

Instructions for General Use

There are various kinds of TENS, but here are the general instructions to operate it:

  • Clean and dry the area of the body to place the electrode pads.
  • Apply the pads to the desired area. Make sure to attach them securely.
  • Turn on the machine and select the desired level of intensity.
  • Gradually increase the intensity until it reaches a comfortable level.
  • Keep track of the pain levels and adjust the settings as needed.
  • Remove the pads before turning off the device.

It is essential to consult with a healthcare professional before using the TENS machine, especially if there are any underlying health conditions.

Waterproof TENS Machine: How TENS Works

People looking for a waterproof TENS machine do not need to be disappointed. TENS is effective, and they are built to work well without water. It sends low-voltage electrical pulses through electrode pads. These pulses stimulate the nerves and help to block pain signals from reaching the brain. In addition, it boosts the production of the natural painkillers in the body, which are endorphins.

TENS offers a drug-free pain relief option. By using a device, individuals can have control over their pain. They can adjust the frequency, duration, and intensity levels to suit their needs. It is recommended to use lower frequencies at less than 10 Hz initially. Once they feel more comfortable, they can move to higher frequencies at greater than 50 Hz.

TENS can typically produce results in 15 minutes. However, administering it in lower frequencies takes a longer time to take effect than the higher ones. Nevertheless, the effects of the former stay longer on the body than the latter. People who are suffering from chronic conditions can utilise the lower frequencies. On the other hand, those with acute pains can operate in higher frequencies.


There are several benefits to TENS. Firstly, there are many options to choose from. The machines come in different shapes and sizes that are appropriate for various body parts. There are handheld and wireless units. The wireless one has the option to manually operate or use a mobile application. This can make it more convenient.

Another benefit is its cost-effectiveness. The device is usually more affordable than constantly buying medications. Regular TENS therapy can lessen the amount of pain they feel. Thus, they do not require much treatment anymore. People can also operate it many times for different conditions.

Waterproof TENS Machine: Usage Guidelines

TENS machines are powered by batteries or power adapters. People can then use it anywhere and anytime. Therefore, having a waterproof TENS machine is not necessary. This is another reason why there are no units of that nature available. Aside from batteries, a traditional unit has wires. They must attach it to the machine and pads before use.

Pad placements are a vital aspect of the success of TENS. It is essential to apply the electrodes correctly on the affected area. Individuals can place it on the pain area, as well as above, below, and beside it. Afterwards, they can alternate the pattern to see what works best. They can also operate multiple units at once if it helps their pain management more.

In addition, it is advisable to start with shorter sessions and gradually increase the duration as the body adjusts to the treatment. Furthermore, people should not use the TENS machine while sleeping, driving, or bathing. Also, they should always remember to turn off the device after each use. By adhering to these guidelines, they can safely experience the benefits of TENS therapy.

When To Avoid

It is important to note that there are certain situations when it is recommended to avoid using a TENS device. Firstly, it is when a person has a cardiac pacemaker or any other electronic implant. The electrical current generated by the TENS machine may interfere with the proper functioning of these implants.

Secondly, epileptic people can experience seizures due to electrical stimulation. Therefore, it is important to consult a healthcare professional before use. Lastly, when experiencing severe labour pain or any complications during childbirth, it is important to discuss pain relief options with a doctor.


TENS machines can provide natural pain relief. However, they are not suitable for use in water-based activities or environments where there is a risk of moisture exposure. Otherwise, the pads can lose their adhesion fast. Moreover, safety issues can arise if a TENS unit comes into contact with water. Thus, people cannot acquire a waterproof TENS machine. Nevertheless, electrotherapy is a convenient way of reducing various pains.

Before administering the therapy, it is recommended to consult with a doctor for guidance on the level of intensity and duration that is appropriate. It is also important to carefully follow the instruction manual to ensure effective use. Individuals who want to buy their TENS unit can check iTENS from iTENS Australia, as they provide reliable wireless devices. Their mobile application is user-friendly. Hence, they will not have a difficult time navigating it.
