(HealthDay News) -- Though fair skin may simply be a sign that you protect your skin from the sun, paleness may indicate a health problem that needs to be addressed.

The ADAM Encyclopedia lists these health conditions and problems that may cause pale skin:

  • Anemia, or insufficient red blood cells.
  • Insufficient blood flow to the skin from being cold, having low blood sugar or fainting.
  • Shock.
  • Frostbite.
  • Chronic disease such as cancer or infection.
