What are UV’s
UV’s are ultraviolet rays
emitted by the sun that have a major effect on our body.
They are wavelengths shorter
than those of the visible light we see by or infrared rays that keep us
warm. UV’s release more energy than
other rays and have a greater
effect on our skins health.
UV rays activate vitamin D,
kill certain bacteria, and elevate our mood.
However, UV
rays damage our skin beyond repair. The immediate effect is red skin progressing
to sunburn then tan. In an effort to
protect itself, the skins upper layer thickens and
produces more melanin which gives us a golden color or TAN. The long term effect is
wrinkles, premature aging, or skin cancer.
Ultraviolet energy comes in
2 forms UVA’s and UVB’s. They penetrate
the air, water, glass, and our skin.
Only 10% of UVB rays reach the melanocytes which trigger the production
of melanin. A tan is the trash leftover
from the skin’s battle with the sun.
Our 1st line of
protection is our skin. Other animals
have fur, feathers, and scales. Humans
have few defenses against UV rays. Our
skin’s outer layer thickens and tans in an effort to protect it’s
lower layers. A tan is proof that your
skin has suffered UV attack
Skin cells damaged by UV
rays attempt to repair themselves. If
too many are damaged, as with a severe sunburn, some
cells survive in an altered state. These
mutant cells can progress to cause skin cancer.
The skin’s natural defenses
are not strong enough to protect us
1. During the hottest hours of the day, from
2. If your skin type burns rather than tan
3. If you’re a kid under 12 (a child’s self defenses are immature at this
age)
The protection you need
depends on your skin type, amount of sun, and your age.
·
Babies should
always be protected and kept cool
·
Wear
protective clothing
·
Use an
effective sunscreen suited to the
sun conditions, your skin type, & one that:
1. states broad spectrum coverage - filters UVA &
UVB rays
2. has an SPF of 15 or higher – depending on amount and
kind of exposure
3. is water resistant if sweating or swimming
4. contains vitamin C – it provides additional
protection
5. one that’s easy & pleasant to apply – if you like
it you’ll use it
·
UVA’s don’t “burn” but penetrate deep to do heavy
damage & cause skin aging
·
UVB’s are most intense between
·
Sand, water, concrete & snow reflect and increase
suns burning rays
·
You also need sun protection in winter
·
Sun damage does not go away – it builds up – your
skin has a memory!
·
A high SPF allows you to stay out longer without
burning, it doesn’t give more protection
·
There is
no safe way to tan
