TENS

Speaker 1...So, TENS, or Transcutaneous Electrical Nerve Stimulation, is a non-invasive pain treatment. It works by sending electrical impulses through electrodes placed on the skin, essentially using the gate control theory to block pain signals.

Speaker 2And for many, it provides real relief. But when we look at the bigger picture of aging and mortality, especially with chronic pain, things get complicated. Unrelieved pain itself is linked to accelerated biological aging.

Speaker 1Exactly. We see evidence like a study in *GeroScience* from 2025, PMID 39847262, which found that painful diabetic neuropathy is associated with accelerated epigenetic aging and telomere shortening compared with painless neuropathy. So, pain clearly impacts our biological clock.

Speaker 2That’s a strong motivator to treat pain. But for TENS specifically, what does the evidence say about its long-term use and that connection to aging or all-cause mortality?

Speaker 1This is where we need more research. While TENS can alleviate pain, which might indirectly benefit aging by reducing a known accelerator, direct evidence linking long-term TENS use to *improved* biological aging markers or reduced all-cause mortality is largely unknown. We don't have definitive studies showing it slows epigenetic aging or reduces mortality risk itself.

Speaker 2So, we know untreated pain can accelerate aging, but we *don't* yet have clear evidence that TENS directly reverses or prevents that acceleration in the long run, beyond its pain-relieving effects.

Speaker 1Precisely. Its primary role is pain management. For individuals who genuinely benefit and use it appropriately under supervision, it’s a valuable tool. The question of its direct impact on biological aging or all-cause mortality remains largely unproven, and certainly doesn't come with the same long-term risks associated with some pharmaceutical interventions for chronic pain, like dependence or significant systemic side effects. It’s about balancing the known benefits of pain relief against what’s still unknown about its broader longevity impact.
