Get Good Sunscreen

Jun 21, 2023 | The Healthy Way Newsletter

Summer is finally here!

While exposure during Toronto’s many outdoor events in parks, beaches, and vibrant neighbourhoods can replenish your Vitamin D levels and cure the winter blues, the sun is still a force of nature we must embrace with due caution, even on rainy days like today.

Sunlight is ultraviolet (UV) radiation. Too much sun without protection can cause skin damage, accelerated aging, and an increased risk of developing skin cancer, so invest in a good pair of sunglasses and aluminum-free sunscreen before digging out your sandals.

How does sunscreen work?

Sunscreen works by absorbing, reflecting, or scattering UV radiation before it reaches your skin. But you don’t need to block out the light entirely! Direct sunlight kills bacteria and fungi that may live on your skin. It can lower your blood pressure, regulate your immune system, improve sleep quality, and boost your mood and overall well-being.

Sunscreen and cancer prevention

Exposure to UV radiation from the sun or tanning beds is the most significant risk factor for developing skin cancer. There are two kinds of UV radiation: UVA rays are responsible for premature aging, while UVB rays cause sunburn. Wearing sunscreen every day, even on cloudy days, can help reduce your risk of developing skin cancer and keep your skin looking fresh.

When selecting a sunscreen, look for an SPF of 15-30 for cloudy days and at least 50 for long bouts of sunbathing. Broad-spectrum sunscreen protects against both types of rays and provides the most comprehensive protection.

Chemical and Physical Sunscreens

Physical sunscreen reflects/scatters UV radiation, while chemical sunscreen absorbs it. Physical sunscreens with zinc oxide/titanium dioxide are better for sensitive skin. Avoid harmful ingredients like oxybenzone, octinoxate, avobenzone, and spray-on sunscreens, which can cause respiratory problems. Choose a broad-spectrum sunscreen with an SPF of at least 30 and use it daily to reduce the risk of skin damage and cancer. 

Stay safe and enjoy the beautiful weather!
