Hi Nancy and listers,
Lots of people are affected by shorter hours of light in the winter.
Besides the shorter hours ,the light also looses the red part of the
spectrum. Some people get relief by having a red bulb on in their
presence for five or six hours a day. Other poeple need a full spectrum
light for five or six hours. Over all light should be about 14 hours
minimum a day . Some people may need even more hours of light.
Vita-lights are the best but may be over kill most of the time. A good
Grow Light from the hardware store will work well for most people (
thats a full spectrum fluorecent tube gardening light) There are many
brands available of Grow Lights.
The book *Biological Rhythms in Human and Animal Physiology* has some
very interesting information. Its by Dr. Luce ,1971.
Quotes from the book:
.... Just as some patients notice that their symptoms wax and wane
each day quite a few patients with endocrine illness feel more intense
symptoms during certain seasons of the year....
....there is a seasonal difference in the amount of glycogen stored in
liver cells....
...the action of light involves color (wave length), intensity, and
duration, which may stimulate or inhibit cells, thus governing rhythms
in a manner known as photoperiodism....
....light might trigger the circadian increase of adrenal hormones...
...Blind with cataracts, he found a reduction of the amplitude of the
adrenal and blood cell rhythms and in the basic activity in the
regulatory system involving the hypothalamus, pituitary, and adrenal
cortex. After successful cataract operation basic activity returned to
normal. Quite a few metabolic disorders may attend the loss of light...
...the impact of light upon hemoglobin formation, thyroid activity, and
the livers ability to detoxify foreign substances has been studied....
... the pinal gland is shaped like a tiny pine-cone situated deep in
the middle of the brain between the two hemispheres....it responds to
light....light beginning at birth ,also affects the development of the
gland itself.....light plays a role in the development of the gland
which.....later dictates a rate of sexual development.,,,,potent in the
development and well being of infants....the color of light is
physiologically important....the optic tract resembles a complex cable
system, consisting of a bundle of nerve fibers that run from the eyes to
the back of the head, carrying light messages to the visual portions of
the brain. A small bundle of fibers branches off from the main cable
system and diverges downward to the nerve cell clusters(ganglia)in the
upper segment of the neck. This second optic tract is known as the
inferior accessory optic tract and its fibers terminate in the superior
cervical ganglia....the pinal emits neurohormones after receiving
bioelectric messages from the inferior optic tract...
There is much much more in the book.Too much to go into here, get the
book if the subject interests you. Also try color healing in the new age
books.
Bless you Bob Lee
