UV radiation is not always bad. In small doses, it helps us produce vitamin D that our bodies need. The problem occurs when UV rays come into frequent contact with our skin. The effects can be long-term and damaging. These effects occur over time when our skin is not protected. Here's exactly what you need to know about UV radiation, how it affects us, and how to keep your skin and eyes safe!
UV rays break down into 3 different bands: UVA, UVB and UVC. UV wavelengths vary in size and differ in how they affect our skin and eyes.
UVC is the shortest and not long enough to reach our skin. UVB rays come into contact with the outer layer of the skin. UVA radiation penetrates deeper into the skin, down to the inner layers.
Below is the analysis:
1. UVC radiation
UVC rays are actually the strongest, but are mainly absorbed by atmospheric ozone. They are not usually damaging to our skin.
2. UVB radiation
UVB rays reach beyond the ozone layer to the surface layers of our skin. They are the most widespread cause of redness, sunburn and skin cancer. These rays can cause DNA changes in cells directly and can be a major culprit in skin cancer.
The most important times to stay protected are in the spring and summer months between 10 a.m. and 4 p.m.
3. UVC radiation
UVA rays penetrate the skin the deepest of the 3 different rays. They reach deep into the skin and are the main cause of aging, wrinkles, loose skin and sun spots. They are not the number one culprit, but they can cause DNA changes that can eventually lead to skin cancer.
UVA rays are present all year round and in all seasons. They are able to bounce off reflective surfaces such as water, including liquid and ice or snow. It's vital to make sure your skin and your eyes are protected whether it's summer or winter, day or even night.
Here are some tips to stay protected:
- Choose a hat or UPF 50 clothing to keep your skin safe and protected from harmful UV rays. Use sunscreen for the hottest times of the day (10am-4pm)
- Remember to be careful even in the winter months about UVA rays and be protected when skiing or snowboarding. (UVA rays can reflect off snow or ice.)
Always remember,
Block out the sun, not the fun!
