WHAT TO KNOW ABOUT THE SUN

  • It causes 90% of all skin cancers.
  • Overcast days are not much safer than those that are sunny, as 70-80% of the sun’s ultraviolet rays can get through the clouds.
  • The sun is about 80% stronger when reflected off sand and snow.
  • The sun’s rays increase in intensity about 4% for every 1,000-foot rise in altitude.
  • It’s better to play or engage in sports before 10 a.m. and after 4 p.m. If that’s not possible, try to avoid being out at high noon.
  • The sun weakens the immune system, reducing your defense against infection.
  • In general, people can get all the vitamin D they need for strong bones from fortified milk, salmon, vitamin supplements and/or brief, casual exposure.
  • Zinc oxide provides superior protection from UVB and UVA rays. Your daily sunscreen should have a SPF rating of 30 or higher and should also contain at least 5% zinc oxide.
