The Sun and Your Skin

The Sun and Its Rays

The sun produces two major types of ultraviolet rays. UVB rays are the main cause of sunburns and affect mainly the outer surface of the skin. UVA rays penetrate deeper into the skin and affect tissue cells. Both UVB and UVA rays damage the skin, and getting a moderate to severe sunburn once every two years can triple your risk of melanoma.

While many people believe that you can’t get a sunburn on cold or cloudy days, this is a myth. UV rays can break through most cloud coverings regardless of the outside temperature, which is why you should never assume that the sun can’t harm your skin.

UV Rays and Skin Damage

UVA rays penetrate deeper into the skin’s tissue, affecting a number of tissue cells that make up the skin. Some of the less dangerous effects of UV rays include the breakdown of collagen, which leads to wrinkles. In other cases, your melanin cells are altered, resulting in new freckles and sun spots.

On the more dangerous end of the spectrum, UV rays can lead to skin cancer. UV radiation can damage the genetic material of your skin cells over time. If enough DNA damage occurs, your skin cell growth gets out of control and develops into a tumor. These tumors can become melanoma or spread into other forms of cancer.

Protecting Your Skin

Taking steps to protect your skin from sun exposure will significantly reduce your chances of developing skin cancer and can prevent early signs of aging. To avoid unsafe UV rays, you should incorporate sun-safe behaviors as a part of your daily routine.

  • Wear sunscreen every day, no matter the cloud over
  • Pick a sunscreen with an SPF of 30 or higher
  • Pick a broad-spectrum sunscreen the protects against both UVB and UVA rays
  • Wear protective, tightly woven clothing
  • Seek shade between the hours of 10:00 am and 4:00 pm when the sun’s rays are the strongest

Choosing a Proper Sunscreen

To protect your skin from the sun’s harmful UVA and UVB rays, always choose a broad-spectrum sunscreen with a sun protection factor (SPF) of 30 or higher. Those with lighter and more sensitive skin may require an SPF of 50 or 60. Choosing the sunscreen that best suits your needs can be challenging if you have sensitive skin, are prone to oily skin, or live a very active lifestyle.
