Sun Rays: Harmful or Beneficial?
Human skin has special cells, melanocytes. These cells
provide natural, built-in sun protection. You can see it in action each time you tan. Melanocytes produce dark
brown substance, called melanin, which does not allow sunrays to penetrate deep into the skin layers, as it would
be damaging. At the same time sunlight stimulates cell generation, skin becomes thicker, and therefore more
resistant to UV rays. It turns out the sun is actually good for the skin.
Well... People with fair skin don't have enough
melanin producing cells, their sun protection mechanism is not strong, and
these people get sunburns pretty quickly. UV rays have a very strong biological effect, they can damage protein
molecules and even alter genetic material causing healthy cells become malignant. So tanning is bad.
Could say so, but... Sun energy is good for health. Increased blood flow
to the skin stimulates cell regeneration, helps to fight acne, smooth scars and minor skin imperfections. Sunlight
is a necessary factor for Vitamin D production. Sun stimulates immune system and makes us feel happier and
healthier.
So where is the truth? As always, in the middle.
Human body needs sun, but at the same time it must be protected. To make
contacts with sun enjoyable (as they should be), remember: - The most dangerous sun is between 10 a.m. and 3
p.m.
-
Sunrays penetrate glass windows, so being in the sunny spot inside your house or while driving
is just as dangerous as being outside. - Don't be deceived by cold weather or clouds: clouds let UV rays
through, and UV radiation is not felt as heat.
-
Water won't prevent sunburns as the harmful rays can penetrate water three feet
deep.
Wearing sun block at all times is the best thing you can
do for your skin. Apply it 20-30 minutes before going outside so that the lotion absorbs and starts working. People
with lighter skin should take extra precautions: wear hats, avoid direct sun exposure, use sun block with a higher
SPF and reapply it more often (remember, your skin does not have a strong sun protection mechanism, so it needs
your help).
UV exposure is a major factor of premature skin aging. Sunrays are able
to penetrate deep into the skin, dehydrate it and damage collagen tissues. Free radical damage may not stop there.
Free radicals, the unstable molecules that appear during sun exposure, can damage healthy cells and lead to
cancer.
Skin has a wonderful ability to repair itself and fight off the damage,
but it needs proper nutrition to be able to do it effectively.
To help your skin repair itself more successfully, use products that
contain antioxidants able to halt the destructive activity of free radicals.
Vitamin C, when applied topically, not only neutralizes free radicals,
it boosts skin's ability to repair itself after the sun damage (American Academy of Dermatology, 2002 meeting). It
is also shown to reduce the appearance of wrinkles and help to maintain
an even skin tone.
Coenzyme Q10 is another powerful antioxidant. It is found in beef, fish,
grains, eggs, beans, and spinach. Human body makes its own CoQ10, but the production declines with age. Coenzyme
Q10 has exceptional antioxidant properties. Studies show that it can effectively counteract free radical damage and
provide significant protection against UVA-induced depletion of cell membrane. In other words, it will prevent
damage to collagen and elastin production and help you avoid wrinkles.
Omega-3 fatty acid (alpha-linolenic acid) is essential for healthy
looking skin. Some studies suggest that it may inhibit cancer. Fish oil and many plant oils (canola, flaxseed,
hemp, soybean) are rich in this acid. In cosmetics it is present either as a constituent of another ingredient (for
example: Emu oil) or by itself.
Vitamins E helps to prevent skin dryness and protects against
environmental factors and free radical damage. It is used in creams and lotions that relieve skin redness after sun
exposure.
So stock up with skin armoring lotions, enjoy your summer and keep your
skin safe and beautiful. And if you would like to have a bronze tan all
over, get one in a bottle.
