What is a UV index?

The ozone layer protects the Earth from damaging ultraviolet (UV) radiation. Depletion of ozone, as well other weather fluctuations and seasonal changes result in different levels of UV radiation reaching the Earth at any given time.

The UV Index predicts the ultraviolet radiation levels on a scale of 1-11+, helping people determine proper sun-protection practices.

Several fact sheets explain the UV Index and steps you can take to minimize the risks from overexposure to the sun’s radiation. The site will provide a UV Alert if the level of solar UV radiation is forecast to be excessively high which means the chance of overexposure is greater.

While some sun exposure may be pleasant, excessive sun exposure can dangerous. Skin cancer, sunburn, and cataracts are all results of exposure to excessive UV radiation. The UV Index to plan outdoor activities that reduce sunburn.

The UV Index gives a forecast of the likelihood of sunburns. The Index predicts UV intensity levels on a scale from 1 to 11+ where 1 indicates a minimal risk of overexposure and 11+ is a high risk.

The UV Index is calculated on a day-to-day basis for cities across the globe. It also takes into account clouds as well as other local conditions that can alter the amount of UV radiation reaching the ground across different regions of the country.

Overexposure to sunlight is a major issue for all skin types. While overexposure to UV radiation could have severe adverse health effects for all individuals, not all are at risk.

You could be at risk of developing skin cancer as an example.

  • if your skin always burns;
  • If you’re sporting red or blond hair,
  • If you have blue, green, or gray eyes.

There are additional factors that indicate a higher risk of developing skin cancer.

  • a history of blistering sunburns in early childhood,
  • The presence of many moles or
  • a family history of skin cancer.

However, it’s recommended to take note that all individuals, no whatever skin type, are at risk of eye injuries.

UV Radiation and the Health Effects it has

The destruction of the Ozone layer reduces our natural protection from harmful ultraviolet (UV) radiation. This Web page provides an overview of major health problems linked to overexposure to UV radiation. Becoming aware of the risks and taking sensible precautions will let you have fun in the sun while reducing your risk of developing health issues caused by sun exposure.

Skin cancer

Every year each year, the U.S. diagnoses more skin cancer cases than all other kind of cancer. In their lifetime about one-in-five Americans will suffer from skin cancer. Every hour, an American gets diagnosed with skin cancer. Skin cancer is more likely to develop due to exposed UV radiation exposure.

Melanoma

Melanoma is the most deadly type of skin cancer is now one of the most prevalent cancers in teens and young adults between 15 to 29. Melanoma causes about 3 percent of all skin cancers. Yet, it accounts for over 75 percent of skin cancer deaths. UV exposure and sunburns, particularly during childhood are risk factors. Some melanomas may not be exclusively sun-related–other possible influences include genetic causes as well as immune system issues.

Nonmelanoma Skin Cancers

Non-melanoma skin cancers can be less fatal than melanomas. They can, however, spread in untreated cases, which can cause the appearance of a person and more serious health problems. Basal cell carcinoma, as well as squamous cells carcinoma, are two of the most common kinds of non-melanoma skin cancers. These two kinds of cancers are extremely rare when discovered early.

Basal cell cancers are often found in skin cancers. They are typically found in the form of small, fleshy bumps or nodules on one’s neck and head. But, they may also be seen in other places of the skin. Basal cell carcinoma develops slowly, and it rarely spreads to other areas of the body. However, it may infiltrate bone and cause serious damage.

Squamous cell cancers are tumors that may appear as nodules or red, scaly patches. Cancer may develop into large masses, and, unlike basal cell carcinoma, it can spread to other parts of the body.

Premature Aging and Other Skin damage

Other skin disorders caused by UV exposure include actinic keratoses and premature aging of the skin. Actinic Keratoses is a skin condition that is seen on parts of the body that are exposed to the sun. The hands, face forearms, and the “V” of the neck are most susceptible to this type of lesion. Though they’re not malignant, actinic lesions are a potential risk factor for Squamous Cell Carcinoma. Be aware of reddish, raised, or rough-textured growths. Get prompt medical attention should you spot them.

Age-related prematurely can be caused by prolonged sun exposure. This may result in the skin getting thicker, wrinkled, and more leathery with time. Because it is gradual with the majority of cases manifesting in the years following the majority of the sun’s exposure aging prematurely is typically seen as an inevitable normal consequence of growing older. The sun’s UV rays can trigger around 90% of visible skin changes that are commonly caused by aging. Most premature skin aging can be avoided with the use of sunscreen.

Cataracts, as well as other eye injuries

Cataracts are an example of eye damage that causes a loss of transparency in the lens of the eyes cloud vision. If untreated cataracts can cause blindness. Research has proven that UV radiation can increase the risk of developing certain cataracts. Although curable with modern procedures for eye surgery cataracts affect the eyesight of millions of Americans and can cost billions of dollars of medical treatment every year.

Other types of eye damage include Pterygium (tissue growth that could block vision) as well as skin cancers in the eye area, and degeneration of the macula (the portion of the retina in which visual perception is at its highest). Eye protection can reduce all of these issues. If you wear contact lenses, sunglasses, or glasses, you should look for sunglasses that offer 100 to 99 percent UV protection.

Immune Suppression

Scientists have discovered that excessive exposure to UV radiation could cause the body to stop the proper functioning of the body’s immune system and the skin’s natural defenses. For instance, the skin typically defends against foreign invaders such cancers and infections. Excessive exposure to UV radiation could make the skin less tolerant to these invaders.

  • Wear a wide-brimmed cap and if possible, tightly woven and full-length clothes.
  • Wear UV-protective sunglasses.
  • Avoid sunlamps and tanning salons.
  • Check for the UV Index daily.

Take precautions in order to avoid excessive exposure to sunlight However, you should be extra careful to follow the UV Index recommendations when levels are moderate to high. You can find UV Index reports in local media and newspapers.
