All about a TENS unit during menstruation

Menstrual cramps are a common phenomenon associated with PMS (premenstrual syndrome). These cramps can range from very mild to severe. Usually, you can resort to home remedies if the pain is not out of control. Hot water therapy is beneficial, but the results are not ideal in cases of moderate to severe pain. Popping painkillers can give you instant results, but that is not the solution in the long run. It can cause acidity, ulcers, low blood pressure, and other gastronomical problems. Acupressure and acupuncture are mild therapies. You need a solid way to conquer the menstrual cramps that is safe and drug-free. This is where a menstrual cramp relief device comes into play. Let us understand the entire mechanism of a TENS unit for period cramps.

What is the TENS unit

A TENS (transcutaneous electrical nerve stimulation) device is specially engineered to combat menstrual cramps. Women of all ages can easily use this TENS unit for period cramps. This is a small device that is worn like a belt on the abdomen. There are electrodes on the belt that you have to stick to your skin with the help of gel pads.


A TENS device’s electrodes deliver a low-voltage electric current to your body, preventing pain signals from reaching the spinal cord and brain. According to the research studies, the vibrations from the TENS device and the menstrual cramps occur simultaneously, but the vibrations from the device reach the brain first. This blocks the feeling of pain from reaching the brain. You will feel a tingling sensation as it relieves muscle tension and pain. This device is worn at or around the area of menstrual cramps.


This TENS unit for period cramps relieves the pain by blocking the pain signals and stimulating the brain. It also helps release happy hormones (endorphins), which act as natural painkillers for the body. Endorphins interact with the brain and reduce pain perception.

Usage frequency

A TENS device can be used as much as you like, but for a beginner, it is recommended to start with 20–30 minutes. Then, you may remove it for some time before wearing it again. Long-term usage may cause some skin irritation in the area around the device.


The gel pads can be used for about 8–10 times before their stickiness wears off. When the stickiness of the gel wears off, you can replace the pads. You can extend the life of the device’s gel pads by applying the electrodes to clean, dry skin that is free from any body lotions.

Pain relief

The duration of pain relief from a TENS unit varies from woman to woman. Studies have shown that some women experience menstrual pain as soon as they take off the device. Some women have reported getting complete relief from cramps for the whole day after the nerve stimulation is stopped. Some studies have proven that the effectiveness of a TENS unit increases with increased use. Some have also reported that the tolerance level for pain increases with the use of a TENS device.

Sleeping with a TENS unit

Sleeping while wearing a TENS unit is fine, but you need to be careful. If you have a lot of movements during sleeping, then the gel pads can come off or the cords can become entangled. You may set a wake-up alarm every 30 minutes to remove the electrodes.

Avoiding TENS unit

There are a few conditions under which you should not use a TENS device. If you have an implantable device like a stent or a pacemaker, if you are suffering from epilepsy or a heart condition, or if you are pregnant, then a TENS device is strictly a no-no. Cancer patients and those who have recovered from cancer for less than 5 years should not use a TENS unit.
