“is a general stimulus to the body, more potent if applied after a period when it has been lacking
which gradually loses its effect if exposure is over prolonged, even when not excessive”.
E. Over many years of study, dermatologists have proven that excessive exposure to sunlight
for years is responsible for a large proportion of skin cancer amongst the population. Those
with the greatest chance of doing permanent damage to their skin are the year-round outdoor
workers – 90% of which occurs on the heavily exposed hands and face. The first line of defense
against permanent sun damage is the skin’s own natural fatty matter and sweat, which
combine to form an oily acid surface shield against the ultraviolet rays.
At the beach, the saltwater washes away this natural oily coat, the hot sun overworks the
sweat glands so that the excess becomes ineffective and the dry wind and hot sun combine to
dehydrate the skin itself. Over the years, women have shown far greater wisdom in the care of
their skin than men. Since the ladies of ancient Egypt first began to apply the fat of the so-
called sacred temple cats to their faces, women have been tireless in waging this battle against
damage to the skin from the sun. Both sexes now contribute annually to a multi-million dollar
global sunscreen business.
F. Other pans of the human body which tend to suffer from exposure to the sun are the eyes
and hair. Many years ago, optometrists undertook studies in America to examine the influence
of the sun upon the eyes by studying Atlantic City lifeguards and found that even a few hours
in the bright sun without sunglasses could cause a significant loss of vision – a loss that might
take several weeks from which to recover.
So gradual was the change that the lifeguards were unaware that their sight had been
affected. The solution to this problem was to introduce sunglasses as a standard part of the
lifeguard uniform. These were dark enough to absorb the sun’s harmful UV rays and most of its
infrared and ultraviolet rays.
G. Of a lesser impact is the effect of the sun upon the hair. The penalty of the sun parching is a
brittle dryness. Haircare professionals recommend a nutritional cream treatment with a
substance containing lanolin to bring your hair back its natural softness, these usually come in
the form of leave-in conditioners, and should be applied frequently, just as you would a
sunscreen for the skin. Or, easier still, wear a hat. Wearing a hat has a dual effect: it protects
the hair and helps to prevent the most dangerous of outdoor afflictions: sunstroke.
