The Body Electric

HAS anyone told you lately you’re electric? Well, you are. Your every pore oozes with the stuff. Must be all those ions you’ve been pumping. And we’re not just talking about nerve impulses here: every surface of your body, from your skin to your cell membranes, is humming with electrical activity.

Biologists have known for more than 200 years that nerve impulses are transmitted electrically. But only recently have they started eavesdropping on the electrical chatter of the rest of your body, and have discovered that electricity, in the form of electric fields, plays a vital role in numerous biological processes from embryonic development to cell division, nerve regeneration and wound repair. “The phenomenon is broadly applicable and I think we have only scratched the surface of something that is evolutionarily highly conserved and widely used,” says Colin McCaig of the University of Aberdeen, UK, who has been working on the biological effects of electric fields since the 1980s.

The Body gets a Healing boost from its inner Electric Fields

THE body’s ability to heal itself partly depends on natural electric fields, it has been proved for the first time. The work could lead to the development of drugs that speed up healing by enhancing these natural fields.

Cell migration and division plays a key role in development and healing. Most research in this area is on chemical factors, but several studies have shown that applying electric fields can affect migration and division as well. After successful trials in animals, for example, a team in the US is trying to encourage the healing of spinal cord injuries by applying an external field.
