Did you know dermatologists recommended we wear a 30 SPF sunscreen every day? The sun's ultraviolet rays are damaging in more ways than we may realize.

Here are five reasons to add an SPF to your daily routine.⁠

1. Reduces our risk of skin cancer by 40 -50%

2. Protects us from premature ageing like dark spots, wrinkles, and sagging skin.

3. Protects us even when it's cloudy out. - Yep, this one's important - UV rays are in abundance even when it's cloudy out, and these are the rays responsible for premature ageing.

4. It provides protection even while indoors, as UVA radiation penetrates windows. So if you are working next to a window, you need protection too!

5. Damage from UV exposure is cumulative, and irreversible, so lets be proactive and get protected daily!

While it’s evident that UV radiation poses a health risk to us, the good news is that we can greatly reduce these risks by taking some simple proactive measures. Knowledge is power, so let's get in the know about UV radiation!

What is UV radiation?

It’s apart of the natural energy that the sun releases. There are three types, UVA, UVB and UVC. Only UVA and UVB reach the Earth. UVC is unable to penetrate the Ozone Layer. UVA and UVB both cause harm to the skin, but in different ways.

Ultraviolet A radiation is related to premature ageing of our skin.

Ultraviolet B radiation is related to sunburns.

UV radiation is responsible for the majority of skin cancers like melanoma. Damage is cumulative and over time increases our risk of cancer.

UVA and UVB facts

UVB

UVB affects the outermost layers of the skin is responsible for sunburns.

UVB is related to the Sun Protection Factor (SPF) we see on our sunscreen bottles. It tells us how long we can be exposed to the sun before reddening should begin to show on our skin. Example. With a 30 SPF, it will take approximately 30 x’s longer for your skin to redden compared to if you weren’t wearing sunscreen at all.

UVB is present all year round, with intensity ranging depending on season and time of day. The sun’s rays are the most powerful mid-morning to late afternoon from spring-fall, but also winter can pose a large threat with reflective surfaces such as ice and snow.

UVB can be filtered and does not penetrate glass.

UVA

UVA is related to tanning and can cause sunburn.

Are related to the “broad-spectrum” aspect that we see on our sunscreen labels.

UVA penetrates the deeper layers of skin (dermis) causing a genetic mutation that can lead to cancer.

UVA causes premature ageing like fine lines, wrinkles and dark spots. UVA is also responsible for certain cancers.

UVA rays are present year-round whether it is sunny or cloudy, and hold the same value of intensity during daylight hours any time of the year.

UVA accounts for 95% of UV radiation reaching Earth, so we are automatically getting lots of exposure from it. UVA is able to penetrate windows.

What Can You Do?

Here's how we can protect ourselves so we can spend some worry-free time enjoying the sun, and doing what we love in the great outdoors. The following are some recommendations from Health Canada’s website.

·     Wear a broad-spectrum sunscreen of SPF 30 or higher daily to protect our skin from UVA and UVB rays. (We recommend a natural mineral sunscreen made without additional chemicals hidden in the ingredients).

·     Cover up - Wear protective clothing when out in the sun, including hats and eyewear.

·     Play in the shade when possible

·     Limit your time outside when the sun’s intensity is at its highest. Peak hours are between 11-3 pm in Canada.

·     Find out the day’s UV rating to set you up for success.

·     Stay hydrated by drinking lots of water and replenishing with electrolytes when applicable.

The first fifteen years of a child’s life is when they’re most vulnerable to UV Radiation

May is national sun awareness month, which makes for a perfect time to improve our knowledge and strategies about sun safety, so we can get out there and enjoy the sun, worry-free.

Spending countless hours in the sun was always one of my favourite pastimes. Until recently, that is, when I learned that I needed to take a more serious look at the dangers caused by UV radiation. It was something my dermatologist mentioned at my last visit that got my ears perked up. She informed me about the significance of early protection from UV radiation, and that the first fifteen years of a child’s life are the most important. Children tend to be most at risk because their skin is very sensitive and very easily burned. Burns are a major contributing factor to the development of skin cancer later in life. Skin cancer is the most common cancer worldwide, with growing numbers annually. Let’s take an in-depth look over what some of these concerns are, and put together a sun-safe plan.

Here Are the Facts, And What Can We Do.

The stats I have discovered are astonishing! The skin cancer deal is real, with 9,500 cases diagnosed daily in the US. There are two different types of skin cancer, Non-Melanoma and Melanoma. Non-Melanoma includes Basal Cell Carcinoma and Squamous Cell Carcinoma. Basal Cell Carcinoma (BCC) is the most common form of skin cancer, and the most frequently formed out of all cancers. BCC occurs when DNA damage from UV exposure occurs. Squamous Cell Carcinoma (SCC) is the second most common type of all skin cancers with 15,000 deaths each year in the US, which is double that of Melanoma. Wearing an SPF of 30 can reduce your risk of developing SCC by 40 percent. Melanoma is the most deadly form of skin cancer and is on the rise, with a 47 percent increase in the past decade between 2010 – 2020. An estimated 196,000 cases of Melanoma will be diagnosed this year in the US. This is serious news!

The following factors increase your risk for developing skin cancer.

Reports show that early protection from a young age is vital and that the most vulnerable time of our lives for sun damage is during childhood and adolescence. So this makes it the most critical time to protect for the future.

Sunburns during childhood are strongly associated with developing skin cancer later in life. They are the leading cause for the majority of cases of skin cancer. The risks of developing a melanoma more than doubles when there is a history of five sunburns or more, or just one blistering sunburn in childhood or adolescence. No matter how mild, any reddening on the skin is a result of DNA damage as a result of the effects of UV radiation. In fact, cellular damage can occur from sun exposure to skin that is tan or darker skin tones, without any signs of reddening. You won’t necessarily feel the damage that is being caused on unprotected skin.

Children’s skin is more sensitive than adult skin because natural skin protection systems are not fully developed. Their skin is more susceptible to burns which makes them more vulnerable. With this knowledge, it’s easy to see how kids are easily prone to sunburns, or cellular damage from playing outside or being in the pool. Kids tend to spend more time outside than adults, and reports show that most of our sun exposure occurs before the age of 18.

Another overlooked aspect is outdoor sporting activities. Kids spend lots of time taking part in after school and weekend sporting activities that take place outside. It is essential to protect their skin, from springtime, to fall, even when it is cloudy out. 90% of the ageing process occurs from skin damage from the harmful UV rays. The rays absorb through the skin and mutate our DNA. Although premature ageing may not be a driving force for applying sunscreen to your kids during soccer practice, UVA rays that are present during cloudy days are also responsible for causing certain skin cancers. Getting in the habit of applying natural sunscreen daily is one way we can indicate the importance of protecting from an early age. Using natural sunscreen is a great option for children as they tend to be better for sensitive skin. Natural sunscreens are usually made with less harsh chemicals like zinc oxide or titanium dioxide which work by forming a reflective barrier on the skin. Conventional sunscreens use chemical UV filters which work by absorbing into the skin, and thus into our bloodstream. These chemical UV filters pose health risks, and have been associated with cancer, endocrine disruption or organ system toxicity.

What We Can Do

It’s easy to reduce the risk of skin cancer by practicing some simple sun safety measures. Here are some recommendations for daily protection.

I've started putting a natural sunscreen in the kid's bathroom so that they can apply some daily to their face, neck and arms.

Special Consideration For Babies

Babies are not born with a developed skin defence system and have thinner skin, so they are at a higher risk for burning. A sunburn for a young child is considered more dangerous as their skin to body mass is much greater. It is advised to keep small children under the age of one out of the sun, but if they are over six months of age, they can have sunscreen applied to areas that are not covered. A sunburn to a child under the age of one is considered an emergency. Contact your doctor right away if this happens.
