We've all suffered through a sunburn at one point or another. After spending a whole day at the beach soaking in the sun's rays, we come home to find out that the slightest movement is painful and sleeping is next to impossible. This aside, many Canadians are in fact aware of the risk of sun exposure, but over 50 per cent do not use any protection.

The sun produces ultraviolet rays (UVA, UVB and UVC). These rays can produce instant effects like sunburn or rashes. It is estimated that they are responsible for 90 per cent of all skin cancers and can also lead to premature aging and even eye damage. Studies show that one serious sunburn before the age of 18 may increase the possibility of skin cancer. According to the Canadian Dermatology Association, damage from the sun is also not immediate. It takes between 10 to 30 years for skin cancer to appear after sun exposure.

And while you may think that you're skin is safe when it's cloudy, cold, foggy or hazy, UV rays can actually weather many conditions.

Sunscreen or sub block with a Sun Protection Factor (SPF) of 15 or higher, which offers protection against UVA and UVB radiation, can help guard against the harmful effects of the sun. SPF refers to a product's ability to stop your skin from burning and available levels range from 2 to 50. Higher SPF rating means better skin protection and the ability to stay in the sun for longer periods before burning.

If you're outside during the times when the sun is at its strongest (from 10 a.m. to 3 p.m.) take the following preventative measures :

• Apply sunscreen15 to 30 minutes before going outside to exposed areas including ears, nose, lips and neck;
• Re-apply sunscreen after swimming or exercise and apply generously and liberally throughout the day;
• Rest in shaded areas outdoors; and
• Wear protective clothing and accessories including a broad-brimmed hat that covers your ears and neck, UV-protective sunglasses and a long-sleeved shirt and pants.

These measures are extremely important for children and will greatly reduce their lifetime risk of developing skin cancer or any other damage caused by the sun.
