Light the life blood of all
life forms is used for medical purposes to treat and cure many diseases. Light
which occupies a prestigious first position in the creation has a host of
health benefits. I can simply go on talking, so let me come to the
point, what is light therapy?
Light therapy otherwise known
as photo-therapy or helio-therapy consists of exposure to day light or artificial
sources of light such as lasers, fluorescent lamps, light emitting diodes and
full spectrum lights for medical purposes. Blue light, infra-red light and
ultra violet light is used to treat various diseases.
Blue light is a component of
the visible light and currently being used to treat back pain and bad breath. A
study found that when exposed for just two minutes from lamps used for tooth whitening
the blue light killed all the bacteria which were present in saliva.
Blue light is effective in
killing bacteria associated with destructive gum disease and periodontitis an
oral infection that leads to loss of bone and teeth. The infra red light can be
used for stroke patients and people suffering from Alzheimer’s disease to
increase their well being and health.
Ultraviolet light is used to
treat patients who are suffering from eczema. Light therapy is also used to
treat hay fever, wounds and epilepsy and stomach ulcers. It is also used for
treating psoriasis. A friend of mine found tremendous improvement in the skin
condition after undergoing light therapy.
Deep penetrating light
therapy uses light emitting diodes to treat conditions such as pain reduction,
wound healing, reduction in acne and wrinkles. Researchers found that daily
application of light therapy using light emitting diodes showed marked
improvement in cognitive function of post traumatic stress disorder in patients
with traumatic brain injury.
Researchers have found bright
light therapy can ease bipolar depression in some patients. Scientists plan to
treat near sightedness which can lead to blindness in adults some where in the
not so near future. Light therapy is also used to treat seasonal affective disorder
which is a type of depression affecting people in fall or winter.
Last but not the least go out

you immunity and your well-being.
