We have heard how advanced technology can benefit us, and this is no exception when we start looking at the Light Therapy. The LED’s that produced near-infrared light used in the NASA’s research were shown to stimulate the basic energy processed by activating color sensitive chemicals within the cells. The light absorbed by the cells stimulated the metabolism in muscle and bone as well as skin and subcutaneous tissue. What people and animals had felt through utilizing light technology in real life, NASA proves to be true in the laboratory researches.

Lasers provide low energy stimulation of tissues that result in increased cellular activity during wound healing (Beauvoit, 1994, 1995; Eggert 1993; Karu 1989; Lubart 1992, 1997; Salansky, 1998; Whelan, 1999; Yu, 1997) including increased fibroblast proliferation, growth factor synthesis, collagen production and angiogenesis. LED offers an effective alternative to laser that arranging large, flat arrays allowing treatment of large wound that laser does not. That includes treatment of serious burns, crush injuries, nonhealing fractures, muscle and bone atrophy, traumatic ischemic wounds, radiation tissue damages, compromised skin grafts, and tissue regenerations. As reported (Whelan, 2000), 3T3 fibroblasts (mouse derived skin cells) responded extreme well to light exposure from LED. Cell growth was recorded increased of 150 ~ 200% over untreated controls from the research experiments.

Insomnia is the bane of modern society. Since the introduction of electric artificial light over hundred years ago, nearly half of the landed earth is lit up at night. Artificial light (even it is a great invention of bringing night to be day) disturbs natural circadian rhythms. Chromocyte cells located in our skin carry light wave information to the pineal gland, and the blue wavelength (at dawn) stimulates the cell to turn off pineal gland; whereas, the pink wavelength (at dusk) blocks the blue rays and pineal gland begins producing melatonin. The pineal gland (which associated with the crown chakra that located in the center of the brain) produces the sleep hormonemelatonin only in the dark, and peaks about three hours after dark and last eight to nine hours in adults, longer in children. Without adequate melatonin production, sleep is disturbed, hormones become imbalanced, and the ability to fight disease is diminished. In summary, light therapy helps restore normal sleep patterns in people who can’t fall asleep at night or who wake up too early in the morning.

Last but not least, anti-aging skin care therapy is used to treat all signs of aging, and this become great advantages for all to experiment. The treatments may restore fine, medium, and deep lines, as well as loss of elasticity. As described earlier in the session, light spectrum helps growth of new cells or cell regenerations. The growth of new cells greatly diminish and improve the signs of sun damaged skin, broken capillaries, wrinkles, and fine lines of the skin. All in all, when applied in the facial treatments, the light therapy introduces pain free and require no recovery time after most of the skincare or any health care treatments.
