UV Index

Melanoma is one of the most common forms of cancer for those between the ages of 15 and 29, and it's also the most preventable.

Our behaviour towards the sun and intense bursts of UV exposure may contribute to this higher rate of melanoma. The risk is higher for those with fair skin, red hair or multiple or atypical moles.

Sun Safety Tips:

  • Avoid outdoor activities between 11 a.m. and 4 p.m. if possible.
  • Seek shade.
  • Wear protective clothing, broad-rimmed hats and sunglasses.
  • Apply sunscreen to all parts of the body that are not covered by clothing.
  • Don't use indoor tanning beds. Their rays can damage skin, cause sunburn and increase the risk of skin cancer.
  • Check your skin regularly. Make sure you or someone you know checks hard-to-get-to places, such as your back, back of your neck, ears and backs of legs.

 

UV Index:

Environment Canada's UV Index is a useful tool when it comes to sun protection. It tells you the strength of the sun's daily rays - the higher the number, the stronger the sun's rays and the more important it is to protect yourself.

0 - 2 Low

  • Minimal sun protection required for normal activity.
  • If you're outside for more than one hour, wear sunglasses, cover up and use sunscreen.
  • Reflection off snow can nearly double UV strength, so wear sunglasses and apply sunscreen on your face.

3 - 5 Moderate

  • Take precautions - cover up, wear a hat, sunglasses and sunscreen, especially if you're outside for 30 minutes or more.
  • Look for shade around mid-day.

6 - 7 High

  • You need protection - find shade, get out sunscreen, hats, sunglasses and cover up. Unprotected skin can be damaged and burn quickly.
  • Try and stay out of the sun between 11 a.m. and 4 p.m.

8 - 10 Very High

  • Extra precautions required - find shade, cover up, wear a hat, sunglasses and sunscreen. Unprotected skin will be damaged and can burn quickly.
  • If you can, avoid the sun between 11 a.m. and 4 p.m.

11 - Extreme

  • This is very rare in Canada. Maximum protection is required.
  • Avoid the sun between 11 a.m. and 4 p.m.
  • Stay in the shade cover up and wear a hat, sunglasses and sunscreen because white sand and other bright surfaces reflect UV and increase UV exposure.
  • Unprotected skin will be damaged and can burn in minutes.
