>> Light Therapy
therapy or phototherapy consists of exposure to
specific wavelengths of light using lasers, LEDs, fluorescent
lamps, dichroic lamps or very bright, full-spectrum light,
for a prescribed amount of time. It has proven effective in
treating Acne vulgaris, seasonal affective disorder, and for
some people it has ameliorated delayed sleep phase syndrome.
It has recently been shown effective in non-seasonal depression.
Proponents claim demonstrable benefits for skin conditions
such as psoriasis and, more controversially, a degree of "skin
medical books are filled with explanations of the importance
of getting enough light. For example, the ancient Ayurvedic
physician Charaka who lived in the sixth century B.C., recommended
sunlight to treat a variety of diseases. For thousands of
years people the world over have revered the sun as a great
healer; some ancient cultures even worshiped the sun.
1980, A.J. Lewy and coworkers published an article in Science
that ushered in the modern era of phototherapy. Lewy suggested
that secretion of the hormone melatonin could be suppressed
by exposing subjects to bright artificial light but not to
light of ordinary indoor intensity. It has been shown that
melatonin in animals is secreted at night by the pineal gland
under the influence of a circadian rhythm. Light rays impinging
on the retina are converted into nerve impulses, which influence
the secretion of melatonin by connections between the retina
and the hypothalamus. This demonstration that one physiologic
effect of light in humans, transmitted presumably via the
hypothalamus, has a threshold intensity far higher than that
required for vision, suggested that there might be other effects
of light on the brain that require high-intensity light.
is no doubt that the sun plays a very important role in our
daily lives. During winter, the well-to-do vacations in Caribbean.
The summer months are synonymous with spending time in the
beach, in spite of all the warning of the potential to get
skin cancer. We feel better after spending time in the sun.
Today, most of the doctors and medical researchers view the
sun more as a healer than a hazard.
know that lack of sunlight can result in nutritional deficiencies.
Without sunlight vitamin D cannot be metabolized in the human
body, which can result in rickets. Most enzymes, hormones
and vitamins need light for proper functioning. Studies have
shown that different lights affect different enzymatic reactions
for healing purposes. For example, one of the first test a
pediatrician do to a new-born baby is to check for jaundice.
If found positive, they are placed under a blue light to cure
the disease. So, most of us are given light therapy, without
us being aware of it.
Mester of Budapest University conducted experiments to determine
the function of light in the cells of animals and humans.
He found that the monochromatic light promotes the DNA to
use the lipoprotein in the area enabling the the cell to function
better as well as to produce collagen and elastin.
