Are Sun Rays Harmful

The sun’s rays can be harmful to your skin and eyes. The sun’s rays contain ultraviolet (UV) radiation, which can cause skin cancer, premature skin aging, and cataracts.

Skin Cancer

The sun’s UV rays can damage the DNA in your skin cells. This damage can lead to the development of skin cancer, the most common type of cancer in the United States. Skin cancer can be deadly, but it is also highly treatable if it is caught early.

Premature Skin Aging

The sun’s UV rays can also cause premature skin aging, which is characterized by the development of wrinkles, age spots, and leathery skin. Premature skin aging can be unsightly, but it is not life-threatening.


The sun’s UV rays can also damage the lens of your eye, which can lead to cataracts. Cataracts are a clouding of the lens that can impair vision. Cataracts can be treated with surgery.

How to Protect Yourself from the Sun

There are a number of things you can do to protect yourself from the sun’s harmful rays:

  • Wear sunscreen with an SPF of 30 or higher. Sunscreen should be applied to all exposed skin, including the face, ears, neck, and lips.
  • Wear sunglasses that block 99% of UVA and UVB rays. Sunglasses should fit snugly and should not have any gaps around the lenses.
  • Wear a hat with a wide brim. A hat will help to protect your face, ears, and neck from the sun’s rays.
  • Seek shade during the middle of the day. The sun’s UV rays are strongest between 10am and 4pm. Avoid being in the sun during these hours.
  • Stay hydrated. Drinking plenty of fluids will help to keep your skin hydrated and protect it from the sun’s rays.

By following these tips, you can help to protect yourself from the sun’s harmful rays and reduce your risk of developing skin cancer, premature skin aging, and cataracts.
