GOOD SUN,
BAD SUN,
We can't live without
it, yet we can't live
(unprotected) with it.
The sun lowers blood pressure and improves
sleep. It ensures the formation of vitamin D,
has an influence on the hormonal and immune
systems, and lifts the mood. But it also
causes the skin to age faster, can damage
eyes, trigger allergies, lead to sunburn if left
unprotected and, in the worst case, cause skin
cancer. With the help of Witzleben Apotheke,
we find out what else we should know.

UV RADIATION FROM THE SUN
The natural UV radiation from the sun is divided
into UV-A, -B and -C radiation. The longer-wave
UV-A radiation reaches the earth largely unhindered.
Depending on the state of the ozone layer, up
to 10% of the high-energy UV-B radiation reaches
the earth's surface. If the ozone layer is damaged,
the percentage increases. The particularly highenergy
UV-C radiation is completely filtered out
in the upper layers of the atmosphere.
The strength of the natural UV radiation on the
earth's surface also depends on the location
and the position of the sun. In addition, water,
sand and snow reflect the sunlight and thus
intensify the radiation.
INFRARED A RADIATION
Unfortunately, some wavelengths in the shortwave
range of heat-transferring infrared rays,
called infrared A radiation (IR-A), promote premature
skin aging due to so-called free radicals.
These are aggressive oxygen compounds
that can damage the body's cells. Since it has
not yet been possible to filter out these IR-A
rays, we offer sun protection products that
contain a special IR-A protective complex. This
is directly active in the skin cells and prevents
the breakdown of valuable collagen, which is
important for skin elasticity.
NATURAL CALLOSITY
The sun's UV-A tends to tan quickly, but not
lastingly. It is the radiation that can cause
allergic reactions. UV-B radiation, on the other
hand, which can ultimately also trigger skin
cancer, stimulates enzymes in the melanocytes
to produce the skin pigment melanin. Even
with a low dose of radiation, the skin becomes
