At 7 a.m. it is 0 degrees and 95 percent humidity. Dy the
moon, most people have decided to go swimming and
lounge around a pool.
Tar Heels are sun worshippers sitting around the cut
door swimming pool, playing tennis or sunning in McCbfkle
or Polk Places (more commonly known as the quad between
Wilson Library and South Building).
Cut doctors warn against prolonged exposure to the sun.
Dr. Robert S. Tomsick, assistant professor in dermatology at
the North Carolina Memorial Hospital, is a skin cancer spe
cialist. The skin changes after it is exposed to the sun over
many years, he said, and excessive exposure to the sun can
cause premature aging of the skin, brown spots, wrinkling
and skin cancer. ,
Most North Carolinians of English descent with blond or
red hair and a light clear complexion should be more con
scious of protecting themselves in the sun. Blacks, however,
have a built-in sunscreen, Tomsick said.
"Most sunscreens contain a chemical agent PABA or para
am inobenzeoic acid, which is an effective block of ultraviolet
light that causes skin cancer as well as aging changes," he
said. "The government rates sunscreen products from two to
15. Two has negligible protection. The Sun Protection Factor
most effective is 1 5."
All creams, lotions and oils have an SPF, a standard for
measuring the protective powers of sunscreen products. The
length of time each SPF will protect a person from surlburn
varies, depending on skin type, locale, health and other'
factors. Persons with fair complexions who tend to bum
easily should use a product with an SPF of 1 5, Tomsick said.
Dr. Clayton E. Wheeler, chairman of the dermatology de-
partment at NCMH said, "I think the incidence of cancer is
related to sun exposure.' "
The use of sunscreen products usually prevents sunburn.
Wheeler said, but many doctors believe sunburn causes skin
changes which may eventually result in skin cancer.
Repeated exposure to the sun's rays can lead to certain
types of cancer, such as basaf-ce'l and squamous-cell carci
noma (nonmelanoma cancers) and the more serious melano
ma cancers. Nonmelanoma cancers occur almost exclusively '
on sun-exposed areas of the body such as the face, hands and
One of the least common forms of cancer is called a mel
anoma. It is a black or dark brown spot on the skin that may
resemble a mole. Tomsick said the area may begin to grow
and itch or bleed. The area also may change colors very
rapidly. '. "
The other types of cancers are not pigmented, Tomsick
said. They may appear as raised lumps, a little red and may
or may net be scaly.
"Skin cancer is a disease of an older age group in the 40s
end beyond since it is cumulauve," he said.
But individuals in their 20s or 30s also may develop mela
nomas, although infrequently,, and generally on the face. .
The cure rate of skin cancer dzpends on the type of cancer,
its location and how far along it is.
If caught early enough and treated, there is a 60 percent
cure rate (the cancer will not return after its removal), Tomsick ,
Some advice for sun worshippers:
Clouds can filter out a lot of visible and infrared rays
while letting through as much as GO percent of the ultraviolet
radiation from the sun. Many people are deceived into stay
ing out for hours at a time on cloudy, overcast days and may
suffer severe sunburns.
Avoid the midday sun from 11 a.m. to 3 p.m. daylight
savings time when ultraviolet rays are most intense.
Use a sunscreen product with an SPF level for your
complexion and apply it regularly when you are in the sun,
especially after swimming and exercise.
As mid-July temperatures soar,
heat exhaustion and strokes occur
By ANN PETERS
Along with the summer sun comes increased
outdoor exercise and work, and also increased
incidents of heat exhaustion and heat stroke.
Dr. Joseph DeWalt, director of Student
Health Services' Sports Medicine, said heat
exhaustion could affect most people who
are active outdoors.
The symptoms of heat exhaustion include
light hcadedness, rapid pulse, hyperventila
tion, numbness in the hands or mouth, mod
erately elevated temperature and fainting.
"Heat exhaustion is a fairly frequent oc
currence and common complaint" DeWalt
said. "Heat exhaustion can occur with people
who jog more than 3 miles a day and who
don't make any provisions for replacing water
When a person sweats, he loses water and
other nutrients from the body, DeWalt said.
If only water is replaced, a person may ex
, perience muscle cramps in his legs or abdo
men. People, also should be aware of sodium,
potassium and calcium losses, and should
replace these nutrients.
Potassium can be found in citrus fruits,
bananas and raisins. Calcium can be found
in dairy products, especially milk.
Cut DeWalt said, 75 percent of the black
population has a deficiency of an enzyme
that helps calcium to be used effectively in
the body. He said he usually advises black
athletes who came into Sports Med to use
calcium tablets. But the use of supplementary
sodium tablets is usually not necessary since
many foods contain salt

"Keeping the weight loss to 3 to 5 percent
of the body weight while exercising or play
ing can reduce the danger of heat exhaus
tion," DeWalt said.
Common hazards are self-treatment or
self-diagnosis of the problem. DeWalt sug
gested drinking any liquid and going directly
to the nearest medical facility. Running with
a friend also was suggested in case of light
headedness or unconsciousness.
"The most "dreaded condition is heat
stroke," he said. "There is usually a strong
family history of heat stroke, it is more pre
valent among obese people and women tend
to have heat strokes more often than men.
"As an individual works and plays in the
heat, the body becomes better equipped to
handle the heat The only way to prevent
heat stroke is intelligent exercise."
Heat stroke is the inability to maintain an
internal body temperature compatible with
the humidity and temperature conditions the
individual is working with, DeWalt said.
