If there is NO sun, there would be NO life.
That's because all the energy we get is
directly or indirectly from the solar energy.
Sun provides heat and light necessary for all
our life processes and metabolic activities.
Plants prepare food through photosynthesis
which requires sunlight. Further we all get energy
from THAT food which plants prepared using sunlight.
So simply, the sun is the ultimate source of energy in
the universe and without it, we cannot live at all!
The best and most prolific source of Vitamin-D
comes as a direct result of exposure to sunlight.
This is a complicated process and requires many
steps in the body until the product the body needs
is realized. That is the natural conversion of certain
biochemicals in the body that eventually become the
natural source Vitamin-D we need to thrive which is
Vitamin D-3
Vitamin D deficiency causes some cases of depression, evidence exists that the incidence of depression
have increased over the last century. During that time, humans have reduced their sunlight exposure via
urbanization (tall buildings and pollution reduce UVB ), industrialization (working inside reduces UVB exposure),
cars (glass totally blocks UVB), clothes (even light clothing blocks UVB), sunblock and misguided medical advice to never let sunlight strike your unprotected skin.
Vitamin D rapidly increases the in-vitro genetic expression of tyrosine hydroxylase
(the rate-limiting enzyme for the catecholamine biosynthesis) by threefold
Summer sunlight increases brain serotonin levels twice as much as winter sunlight,
a finding compatible with both bright light in the visible spectrum and vitamin D affecting mood.
Evidence exists that major depression is associated with low vitamin D levels and that depression
has increased in the last century as vitamin D levels have surely fallen. Evidence exists that depression
is associated with heart disease, hypertension, diabetes, rheumatoid arthritis, cancer and low bone
mineral density, all illnesses thought to be caused, in part, by vitamin D deficiency. Finally, vitamin D
has profound effects on the brain including the neurotransmitters involved in major depression.
