The skin is the body's largest organ. It protects against heat, sunlight, injury, and infection. Yet, some of us don't consider the necessity of protecting our skin.
The need to protect your skin from the sun has become very clear over the years, supported by several studies linking overexposure to the sun with skin cancer. The harmful ultraviolet rays from both the sun and indoor tanning "sunlamps" can cause many other complications besides skin cancer - such as eye problems, a weakened immune system, age spots, wrinkles, and leathery skin.
There are simple, everyday steps you can take to safeguard your skin from the harmful effects of UV radiation from the sun.
UV rays are their strongest from 10 am to 4 pm Seek shade during those times to ensure the least amount of harmful UV radiation exposure. When applying sunscreen be sure to reapply to all exposed skin at least 20 minutes before going outside. Reapply sunscreen every two hours, even on cloudy days, and after swimming or sweating.
UV rays can also penetrate the structures of your eyes and cause cell damage. According to the CDC, some of the more common sun-related vision problems include cataracts, macular degeneration, and pterygium (non-cancerous growth of the conjunctiva that can obstruct vision).
When planning your outdoor activities, you can decide how much sun protection you need by checking the Environmental Protection Agency's (EPA) UV index. This index measures the daily intensity of UV rays from the sun on a scale of 1 to 11. A low UV index requires minimal protection, whereas a high UV index requires maximum protection.
