Is the Sun Really That Dangerous? The sun emits ultraviolet rays with two types—ultraviolet A and ultraviolet B. While the two types of rays work slightly differently, both can cause damage to your skin and lead to an increased risk of developing skin cancer. In fact, UVA rays in particular are known to make it through to earth even on overcast days. Some 80% of these rays pass through the clouds, which is why it’s vitally important to protect your skin even on days that the sun isn’t shining as brightly.
Ways Sun Can Be Damaging

- Increases signs of aging
- Promotes wrinkles and skin spots
- Puts you at risk of heat stroke and heat rash
