Sun safety

Information about the harmful effects of extreme heat and ultraviolet (UV) radiation, including skin cancer, as well as first aid tips for sunburn and heat illness.

Extreme heat

Many places in Canada have a high number of extreme heat events, often called "heat waves." Extreme heat can put your health at risk, causing illnesses like heat stroke and even death.

First aid advice for sunburn and heat illness

Sunburn (also called erythema) is caused by overexposure to ultraviolet radiation (UV rays).

Health effects of ultraviolet radiation

Ultraviolet (UV) radiation has some benefits. But as with all forms of radiation, there are risks involved with overexposure to UV radiation (rays).

Skin cancer

Skin cancer is the most common of all cancer types. About one third of all new cases of cancer in Canada are skin cancers, and the rate continues to rise. Skin plays a vital role in keeping you healthy.

Sun safety tips for parents

Too much sun can be harmful. Babies and young children have sensitive skin that can be damaged easily by ultraviolet radiation from the sun (UV rays). This page offers information and tips to help you keep your children safe.

Sun safety basics

Most of us like to work, play, and relax outside on a sunny day. But too much sun and heat can be harmful, so be careful!

Sunglasses

It is important to protect your eyes against damage from the sun. For most people, a low-cost pair of sunglasses with UVB and UVA protection will do the job.

Sunscreens

Being in the sun too long can cause sunburns and skin cancer. It is important to wear sunscreen and take other sun safety steps to protect yourself from the sun's harmful ultraviolet radiation (UV rays).

Tanning beds and lamps

If you think going to a tanning salon is a safe way to tan, think again. There is no safe way to tan.

Tanning products

Canadians use many different types of tanning products. Some are used to prevent tans and sunburns. Others are used to help create or fake a tan.

The ultraviolet index and your local forecast

The ultraviolet (UV) index is a useful tool when it comes to sun protection. It was developed by Environment Canada to inform Canadians about the strength of the sun's ultraviolet radiation.

What is ultraviolet radiation?

Ultraviolet (UV) radiation comes from natural sources (like the sun), and artificial sources (like black lights, welding equipment, lasers, and tanning beds and lamps).
