Odd isn't it?
For more than a decade, researchers have been studying how light-emitting diodes, or LEDs -- miniscule, ultra-efficient bulbs like the ones found in digital clocks and television remotes -- might aid in the recuperative process. NASA, the Pentagon and dozens of hospitals have participated in clinical trials. Businesses have sold commercial LED zappers to nursing homes and doctors' offices.
In a 2002 study backed by the National Institutes of Health and the Persistence in Combat program from the Pentagon's research arm, Dr. Harry Whelan (a neurology professor at the Medical College of Wisconsin) used LEDs to restore the vision of blinded rats. Toxic doses of methanol damaged the rats' retinas. But after exposure to the flashes of infrared light, up to 95 percent of the injuries were repaired.
Human trials have been less dramatic, but still shockingly effective. Using a Food and Drug Administration-approved, handheld LED -- playfully called Warp 10 for its Star Trek style -- wound-healing time was cut in half on board the USS Salt Lake City, a nuclear sub. Diode flashes improved healing of Navy SEALs' training injuries by more than 40 percent. And a Warp 10 prototype was used by U.S. Special Forces units in Iraq, Whelan asserts.
Magazines and television crews have drooled on cue. Medicare has even approved some LED therapy.
And nobody can explain how or why it seems to work....
