Not only do you need a sunscreen,
but you also need to wear your sunglasses. The
shade of a tree can be very deceiving. The tree's
leaves do block out ultraviolet radiation. However,
UV rays have a much shorter wavelength. There
are molecules and particles in the air that can
scatter the shorter wavelength ultraviolet radiation.
So rays landing just outside the range of the
tree's canopy can ricochet off air molecules,
and still land on your skin, resulting in skin
aging and risk of skin cancer.
Sun exposure has been linked to several serious
eye diseases. Keep your cool by wearing your shades.
Buy sunglasses that block both UVA and UVB rays.
Ideally, the sunglasses should also block blue
light. A tight-fitting or wraparound pair will
prevent sunlight from coming through the sides
of the sunglasses.
Shaving is the easiest, but
can cause red bumps that represent ingrown hairs.
Ditto for waxing which hurts much more.
For permanent hair removal,
see your doctor and ask about the ESC/Sharplan
Epilight Hair Removal System. Other lasers that
are can also be effective include the Coherent
LightSheer, The Altus Medical Cool Glide, The
Cynosure Alexandrite, Sharplan Alexandrite, or
Candela Alexandrite.
UVA rays are rays that show
sun damage to the skin later in life, around late
20's and early 30's. Even though you got the rays
in your teens, the damage appears later on. The
UVB rays burns your skin immediately and you develop
a red sunburn that can be very painful.
The ozone is a thin blanket
which observes harmful ultraviolent light rays
and prevents them from reaching the earth. They
are depleted especially around the south pole
including most of Australia.
Yes, very important. You receive
sun's rays directly onto your face and whatever
else is exposed, plus you receive rays bouncing
off the snow onto your exposed skin. Plus at higher
altitudes more ultraviolent rays penetrate the
sky.
