PEMF and Depression: Can PEMF Support Mental Health?

 

Every year on 10 October, World Mental Health Day encourages conversations around mental health, raises awareness and reminds us just how important it is to talk openly about the challenges so many people experience.

 

So this World Mental Health Day, we wanted to look at an area of research that sits particularly close to what we do at CELLER8:

 

What does the research actually say about PEMF, magnetic stimulation and depression?


 

Magnetic Fields Are Already Used for Depression

 

You may have heard of TMS, which stands for Transcranial Magnetic Stimulation. It sounds complicated, but the basic idea is fairly simple.

 

A coil is placed against the head and produces magnetic pulses that stimulate specific areas of the brain.

 

One form, called repetitive TMS (rTMS), is already used medically for depression. In the US, the FDA classifies rTMS systems for the treatment of Major Depressive Disorder (MDD) as Class II medical devices under specific conditions.

But it's worth noting that TMS and PEMF aren't the same thing.

 

TMS generally uses much stronger magnetic pulses targeted at specific areas of the brain. The equipment, intensity and way the magnetic fields are delivered can all be very different from lower-intensity PEMF.

 

But knowing that magnetic stimulation can interact with the brain raises an interesting question:

 

What Have Researchers Found Investigating PEMF Therapy?

 

Researchers have been studying T-PEMF, which stands for Transcranial Pulsed Electromagnetic Fields.

 

One human study published in 2010 looked at people with treatment-resistant depression (depression that hadn’t responded sufficiently to antidepressant medication) to see the response the participants had. 

 

All participants continued to take their existing medication, but then researchers split them into two groups. One received the real T-PEMF, the other received a sham (fake) treatment. 

 

After 5 weeks, the researchers reported a significantly better outcome in the group receiving the real T-PEMF compared to the sham group. They also reported that improvements began within the first weeks, as well as side effects were few and mild.

 

You can find the study here. 

 

Recently (2026), a study was published where researchers reviewed and gathered studies on low field magnetic stimulation and analysed the results together.

 

They looked at 9 randomised controlled trials, with 571 participants overall. When the results were combined, overall, all participants favoured low field magnetic stimulation over the sham treatments.

So, Could PEMF Have a Future in Depression Research?

 

There’s still a lot to research and learn, but current studies show some really positive findings. 

 

We already know that the brain responds to magnetic stimulation. Specialised approaches such as TMS are already used within medicine, and we also know that many studies are favouring low-field magnetic stimulation too. 

 

So now, researchers can start to answer the next questions:

 

What frequencies work best?

How important is intensity?

How often should magnetic fields be applied? 

 

We don't have all the answers yet, but the fact that we're now able to look across multiple human clinical trials shows just how far this area of research has already come.

 

Important: CELLER8 is a general wellness device and is not intended to diagnose, treat, cure or prevent depression or any other medical condition. The specialised magnetic stimulation devices and protocols discussed in this article are not the same device as CELLER8, and their results cannot automatically be applied to all PEMF devices. If you are experiencing depression, speak to a qualified healthcare professional and do not stop or change prescribed treatment without medical advice.
