Did you know?

Solar radiation is more intense dependent on where you are on the Earth.

Yes, that is true. There are a few factors to consider when dealing with UV radiation.

1. The thinning of the ozone layer is especially prevalent at the earth’s poles. Therefore, the risks of burning are greater at the two extremes, including places such as Australia.
2. The higher the altitude you are at, there is less atmosphere and there may be less clouds to deflect or absorb some of the UV rays, so your chances of burning are higher.
3. Any material that reflects the sun’s rays, such as water, snow, or sand, can increase exposure to UV rays, and cause increased sun damage

Some medications that can increase sun sensitivity

This includes:

• Birth Control Pill
• Isotretinoin (ex.: Accutane)
• Tetracycline
• Some hypertension medications, anti-depressants and anti-psychotics

Be vigilant with sun protection when on these types of medications, and ensure that you discuss any questions or concerns with your doctor.

The Canadian Dermatology Association website, dermatology.ca, has detailed information about sun exposure and medications. Visit the site to learn more.

Any tan is a sign of sun damage

Your goal with sun exposure should be to protect your skin as much as possible while enjoying your favourite outdoor activities. You don’t need to hide in the basement, but you do need to remember that moderation is key. By being reasonable with your sun exposure, you can enjoy the benefits that the sun can give us — improved moods, warmth, etc. — without increasing the risks posed by prolonged sun exposure.

Myth: Clouds filter out the sun's harmful rays

While UV rays may not be as strong on a cloudy day, they are still present. According to the Canadian Dermatology Association, for example, up to 80% of UV rays emitted can still penetrate cloud cover. As every Canadian knows, the weather can change without notice, so it is always important to be prepared.

Therefore, sun protection needs to be a daily habit regardless of the weather or season.

Most lotions and oils work by forming a surface layer of sunscreen ingredients on the skin.

This layer absorbs the sun's UV rays before they can penetrate the skin.

To select the most effective protection, pick a broad-spectrum (UVA-UVB) sunscreen with a minimum of SPF 15, depending on your skin type.

Sunscreen formulas for babies and kids tend to take into consideration the special sun protection needs of different age groups.

This includes the delicate skin of babies and water-resistant formulas for older kids.

If for cosmetic reasons you prefer to add colour to your skin, the safest option is to reach for one of the many self-tanners or bronzing powder products that are readily available in drug stores.

Just remember that a self-tanner will not protect you from the sun, so be sure to use it in conjunction with a sunscreen of at least SPF 15.

No product is a total sunblock

Sunscreen agents either absorb, reflect or scatter UV light. Most lotions and oils work by forming a surface layer of sunscreen ingredients on the skin, which absorb the sun's UV rays before they can penetrate the skin.

To select the most effective protection, pick a broad-spectrum (UVA-UVB) sunscreen with a minimum of SPF 15, depending on your skin type.

Sunscreen needs to be reapplied frequently.

The general rule of thumb is to apply sunscreen every two hours. However, this frequency also depends on your activities: if you are swimming or playing a sport that results in a lot of sweating or friction, you will need to reapply even more frequently.
