Hypothyroidism, temperature regulation, and ethnoscience - Medical
Anthropology
"The importance of sunlight for thyroid function may be related in part to
the increase in vitamin D which it causes, which is only found in animal
foods. It has long been known that consumption of vegetables in the Brassica
family can inhibit thyroid function.
An outdoor lifestyle seems protective against hypothyroidism as described in
the above anthropological studies of various indigenous populations. One
reason may be exposure to sunlight. Morning light advances physical
activity, hormone secretion, urine output, body temperature, and stimulates
the thyroid to burn body fat, while evening light makes the same events
occur later. Farm animals living outdoors don't fatten as easily as those
living indoors. UV stimulates the thyroid to increase metabolism, which
burns calories (Lamberg: 1994). In the 1930s Swiss sun therapists found
clients had little fat even without exercising for months and
well-functioning thyroid glands. (Kime and Lohmeier: 1986). Two hours of
bright light in the morning reduces nocturnal restlessness in patients with
Alzheimers as well as SAD, an affective disorder related to depression, by
increasing serotonin levels. In industrial societies children experience
growth spurts during the spring as their metabolism speeds up and thyroid
hormone s peak."

6. Get some sunlight every day.
There's evidence that exposure to sunlight affects hormones that have an
impact on both brain chemistry and the endocrine system. Even if you don't
suffer from a full-out case of "seasonal affective disorder", 20 to 30
minutes a day of outdoor light exposure can help ward off fatigue and
depression. My doctor's own tip...if you don't want to be outside for
prolonged periods when it's cold, go run errands in your car, but keep the
window open, so you are exposed to the natural sunlight. (Keep in mind,
wearing sunglasses will reduce the benefit of the sunlight.)

Hello,
We have understandings that we get Vit.D and Sunburns by exposing us to
sunlight. We also get visuality and solar energy from it. Some harming
germs may be killed by it. We also get botanical materials growns under
its influence. It is mostly composed of seven wavelengths with some IR
and UV rays. Sun, spritually, is/was also consdered as "god of health
giver".
We have natural and unnatural, continious and prolonged(since our
evolution) exposure to many substances with and without physical
ingestion of them. All objects, on exposure to sunlight, reflect
wavelengths relavent to their colors, absorb and emit others. We are
getting preception and sensations to those reflected or emitted
wavelengths.
I have few questions:-
1. How reflections and emittions from any substance on their exposure
to sunlight can effect us physiologically and psychlogically?
2. Can sensations (taste, thinking, looking, hearing,felling,smelling)
of any food to be taken effects us apart from its ingestion
effect--pre-stomach in view of reflections and emittions from those
foods substance on their exposure to sunlight ? One theory, we have
about "cephalic phase effect".
3. Can such sensations will be a weak effect or weak sumuli and
specific effects to specific part of body WHERAS effects post-stomach
by absorptions may be systematic effect?
4. How as such, following (others pls tell) laws can be related to weak
stumuli pre-stomach by just sensations other that "ingestion effect"
post stomach?
