“Most people think of LEDs as lights for decoration, but Dr. Harry Whelan says near-infrared LEDs can help heal wounds and even treat brain tumors. He was inducted in 2000 into the NASA Space Technology Hall of Fame for this research….” see article

January/February 2004 – Rehab Management: Therapeutic Light
“Light is a form of energy that behaves like a wave and also as a stream of particles called photons. The development of monochromatic light sources with single or a narrow spectra of wavelengths paved the way for studies, which continue to show that appropriate doses and wavelengths of light are therapeutically beneficial in tissue repair and pain control. Evidence indicates that cells absorb photons and transform their energy into adenosine triphosphate (ATP), the form of energy that cells utilize. The resulting ATP is then used to power metabolic processes; synthesize DNA, RNA, proteins, enzymes, and other products needed to repair or regenerate cell components; foster mitosis or cell proliferation; and restore homeostasis. Other reported mechanisms of light-induced beneficial effects include modulation of prostaglandin levels, alteration of somatosensory evoked potential and nerve conduction velocity, and hyperemia of treated tissues. The resultant clinical benefits include pain relief…” see article

November 13, 2003 – NASA: NASA Light-Emitting Diode Technology Brings Relief In Clinical Trials
“LEDs provide light for plants grown on the Space Station as part of commercial experiments sponsored by industry. Researchers discovered the diodes also had many promising medical applications, prompting NASA to fund this research as well, through its Marshall Space Flight Center in Huntsville, Ala. Biologists have found that cells exposed to near-infrared light from LEDs, which is energy just outside the visible range, grow 150 to 200 percent faster than cells not stimulated by such light. The light arrays increase energy inside cells that speed up the healing process…” see report

Oct. 29, 2003 – WIRED News: Light at the End of the Tunnel
“On this much, scientists and doctors agree: Tiny flashes of infrared light can play a role in healing wounds, building muscle, turning back the worst effects of diabetes and repairing blinded eyes. But what they can’t decide on is why all these seemingly miraculous effects happen in the first place. 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…” see article

April 19, 2001 – NASA: Healing Light 
“Experiments with light energy are making everyone happy: farmers, doctors, patients, and astronauts are all reaping the benefits. What began as a way to grow better crops has ended up being a way to help seriously ill patients recover faster. In this case, what’s good for plants is also good for people…” see report

March 5, 2001 – WebMD: Doctors Unveil a Quick, Easy Solution to Aging Skin
“Medicine has yet to find a way to turn back time, but a new procedure may make it easier to at least look younger in no time at all. Called photo rejuvenation, it is one the hottest topics in the field of skin care. This is because the procedure can help improve the appearance of aging or sun-damaged skin…” see article

December 18, 2000 – NASA: NASA Space Technology Shines Light on Healing
“Doctors at the Medical College of Wisconsin in Milwaukee have discovered the healing power of light with the help of technology developed for NASA’s Space Shuttle. Using powerful light-emitting diodes, or LEDs, originally designed for commercial plant growth research in space, scientists have found a way to help patients here on Earth. Doctors are examining how this special lighting technology helps hard-to-heal wounds, such as diabetic skin ulcers, serious burns, and severe oral sores caused by chemotherapy and radiation. The project includes laboratory and human trials, approved by the U.S. Food and Drug Administration and funded by a NASA Small Business Innovation Research contract through the Technology Transfer Department at NASA’s Marshall Space Flight Center in Huntsville, Ala…” see report

November 11, 2000 – Healthlink: Light Emitting Diodes Aid in Wound Healing
“Powerful light-emitting diodes (LEDs) have been shown to help heal wounds in laboratory animals and are now being tested on humans at the Medical College of Wisconsin. The LEDs were developed by the National Aeronautics and Space Administration (NASA) to spur plant life in space. Harry T. Whelan, MD, Professor of Neurology, Pediatrics, and Hyperbaric Medicine at the Medical College of Wisconsin, found that diabetic skin ulcers and other wounds in mice healed much faster when exposed to the special LEDs in the lab. Laboratory research has shown that the LEDs also grow human muscle and skin cells up to five times faster than normal…” see article

July 27, 2000 – WebMD: Beyond Lasers: Pulse-Light Therapy for That Fantasy Face
“It’s not as if Tina Huoso needed a face-lift. At age 31, she was essentially wrinkle-free. A handful of superficial acne scars, reminders of her teen-age years, were just about her only blemishes. But the brown sun blotches that began appearing on her forehead, and especially one above her lip, made Tina self-conscious…” see article
