A Lesson About Sun Safety
UV Radiation
Many types of rays come from the sun:
Heat rays, visible light, and invisible
ultraviolet light or (UV) Radiation.
Two kinds of UV radiation reach the earth:
UVA rays – longer rays, penetrate skin deeply,
and cause wrinkling and tanning
UVB rays – shorter rays which cause burning
of the skin
Tanning and burning of the skin are signs of
skin damage!
The Dangers of UV Radiation
Overexposure to UV Radiation causes:
Sunburn
DNA Damage
Skin Cancer
Premature aging (wrinkles)
Cataracts
Immune system depression
The Structure of Your Skin
 The skin is your body’s
largest organ
 It protects you from the
sun and from infections
 The skin has 2 layers:
epidermis and dermis
 Skin color depends on the
activity of the
melanocytes in the
epidermis
What Causes Skin Cancer?
UV radiation causes increased activity in
the melanocytes
This increased activity is the cause of
freckles, tanned skin and sunburns
Sometimes this leads to changes in cell
structure and function, causing cancer
Do You Know the Three Main
Types of Skin Cancer?
 Basal Cell Carcinoma
75% of all skin cancers
 Squamous Cell Carcinoma
20% of all skin cancers
 Melanoma
5% of all skin cancers but
responsible for 75% of skin
cancer deaths
Signs of Melanoma
What are the ABCD’s?
 Asymmetry
 Border
 Color
 Diameter
 CHANGE!
Who is at Risk for Skin Cancer?
Fair skin, burns
easily
Light hair color
Blue or green eyes
Freckles
Many moles
Family history of
skin cancer
When is UV Radiation
Most Intense?
 In the middle of the day
(Between 10 a.m. and 4 p.m.)
 During the summer months
 At higher altitudes
 In regions of the earth closer to the equator
Use the UV Index as a tool to help plan
your outdoor activities.
Protective Measures
 Avoid midday sun
 Cover up with hats,
clothing and sunglasses
 Use sunscreen
 Apply liberally and often
 Avoid reflective surfaces
 Seek shade when your shadow is shorter than
you are
 Avoid tanning beds
Tanning Beds are NOT Safe!
Loosely regulated; not enforced
Studies show tanning beds are linked
to skin cancer and premature aging
If you must be tan, use a self tanner.

There is no such thing as a safe tan!
