But declines are occurring in the absence of destruction of habitats, suggesting other causes such
as pollution from pesticides, acid rain and increases in
ultraviolet exposure or even change in climate (Blaustein & Wake 1990).
But, because we worry (and rightly so) about skin cancer, we shield our skin from the sun's
ultraviolet light with clothing and sunscreen, which makes it impossible for our bodies to manufacture Vitamin D. Breast milk was never meant to be the source of vitamin D for our babies (
as we are all intended to make our own vitamin D with
exposure to sunlight), but
as we continue to be cautious about
exposure to sunlight, babies do not make enough Vitamin D, nor do they receive enough in breast milk.
The study notes that indoor tanning products can produce 10 to 15 times

ultraviolet exposure, including from indoor tanning.

ultraviolet rays.

as ultraviolet radiation
exposure (UVR).
In humans, these cells function to protect skin from damaging environmental stresses such

exposure.
This last one was surprising, since we think of
ultraviolet exposure as contributing to melanoma idults, but not B - ALL (a leukemia of B - cells) in children.
It is usually caused by excessive
exposure to sunlight or other sources of
ultraviolet light, such

Individuals with lupus should limit
exposure to the sun
as ultraviolet rays can trigger an autoimmune reaction.

as a result of sun
exposure.

exposures, such
as cigarette smoke, air pollution, and
ultraviolet radiation from the sun.
All tortoises should be kept outside,
as temperatures permit, to ensure adequate
exposure to
ultraviolet light, which is necessary to maintain calcium metabolism.

ultraviolet exposure and pigmentation characteristics serve
as risk factors, but so does genetics.

as fugitive dyes and colorants used in paints will eventually discolour under
exposure to this type of light.

as a covariate
as well

as well
as ultraviolet radiation
exposure (Hancock et al., 2008), was controlled for.
