Paging Dr. LED...

LEDs are good for a lot of things, but did you know that they can potentially heal wounds also? According to a 2004 study published in The Journal of Clinical Laser Medicine and Surgery, infrared LEDs can help heal wounds. The study came about thanks to NASA, which was using IR LEDs for plant growth experiments in space. During their research, scientists found that if IR LED light rays were delivered deep into the tissues of the body they could promote wound healing and tissue growth. Once the scientists got a hunch that LEDs could heal wounds, they went ahead and performed some tests. They found that IR LEDs increased cell growth by 155 to 171 percent in humans and wound size decreased up to 36 percent. According to teh study's abstract, ". LED produced improvement of greater than 40% in musculoskeletal training injuries in Navy SEAL team members, and decreased wound healing time in crew members aboard a U.S. Naval submarine. LED produced a 47% reduction in pain of children suffering from oral mucositis." The study concluded that , "the use of NASA LED for light therapy... will greatly enhance the natural wound healing process, and more quickly return the patient to a preinjury/illness level of activity." I guess the question really should be: what can't LEDs do?
