How to stay safe in the sun

Skin cancer is the most common cancer in Canada and skin cancer rates are on the rise. Over the past five decades, Manitoba has seen a large increase in the number of people diagnosed with skin cancer.

Skin cancer is also one of the most preventable cancers. 50-90% of skin cancers are caused by ultraviolet (UV) light exposure, which means that more than half of skin cancers can be prevented.

Sources of UV light (UV) are sun and UV-emitting devices, e.g., tanning beds. UV causes skin cancer and other forms of skin damage (e.g., wrinkling and photoaging of the skin) and causes harm to the eyes. Both UVA and UVB are damaging to skin and eyes.

While UV that is harmful to the skin is primarily present in the sun's rays from 11 a.m. to 3 p.m. between April and September in Canada, UV that is harmful to the eyes is present in the sun's rays all year round and throughout the day. In both cases, UV can be harmful, even when it's cloudy.

You can reduce your risk of skin cancer and other sun/UV damage by following these easy steps:

Use sources of vitamin D that are safer than UV exposure, e.g., dietary sources, including fortified foods, and vitamin D supplements. Intentional UV exposure to meet vitamin D requirements is not recommended.
