Ah, the feel of the hot summer sun on
your skin! After a long, cold winter, it’s
refreshing to spend time in the warmth of
the sun – but BEWARE your health is in
danger not matter how good you think
that tan looks and feels.
A Healthy Tan?
In their favor, ultraviolet (UV) rays produced by the sun activate Vitamin D, kill certain germs and boost our mood – but overexposure to UV rays damages the skin irreparably. The sun’s ultraviolet rays are actually radiation that comes in two types – UVB & UVA rays.UVBs are the immediate sunburn villains – they’re the rays that “roast” your skin.
Though they don’t dive as deep into the skin’s layers as UVAs, UVBs can damage the DNA at the heart of skin cells, and are one of the foremost causes of skin cancer. These same rays also help you by triggering your skin’s natural protection process – tanning. Tanning is really a form of damage control – a tan is living proof that your skin has suffered UV attacks. Keep in mind that these self-defense systems are thrown out of whack when overworked by repeated and prolonged exposure to the sun. UVA is a long wavelength that penetrates the skin very deeply.
