The ozone layer protects the Earth from damaging ultraviolet (UV) radiation. Ozone depletion, as well the variations in weather and seasonal conditions, cause different amounts of UV radiation to be absorbed by the Earth at any time.

What is UV index?

The ozone layer protects the Earth from damaging ultraviolet (UV) radiation. Ozone depletion, as well the variations in weather and seasonal conditions, cause different amounts of UV radiation to be absorbed by the Earth at any time.

The UV Index predicts the ultraviolet radiation levels on a 1-11+ scale that helps people decide on the appropriate sun-protective behaviors.

Numerous fact sheets contain information on the UV Index as well as methods you can follow to reduce your exposure to the sun’s UV rays. If the UV radiation levels are unusually high, the site will show a UV Alert. This indicates that you have a higher chance of being exposed to too much.

Some exposure to sunlight can be pleasant, but too much exposure could be hazardous. Excess exposure to the sun’s UV radiation can cause immediate reactions like sunburn and more long-term health issues such as skin cancer and cataracts. The UV Index provides important information to help you plan your outdoor activities to prevent overexposure to the sun’s harmful rays.

The UV Index gives a forecast of the probability of daily sunburns. The Index provides UV intensity levels based on an index of 1 to 11 where 1 is high risk and 11+ is very high.

Calculated on a next-day basis for dozens of cities throughout the world, the UV Index includes clouds as well as other local conditions that impact the quantity of UV radiation that is reaching the ground in different parts of the world.

People who are more susceptible to sunray-related UV-related diseases are more at risk

It is important to remember that everyone of all skin types should be protected from overexposure to the sun’s rays. Excessive exposure to UV radiation can lead to the development of serious health effects for all people, but not all are equally vulnerable.

For example, you may be at greater risk of contracting skin cancer

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

There are many other factors that increase the risk of developing skin cancer.

  • A long history of sunburns that began to blister in the early years of childhood.
  • The presence of many moles or
  • A family history of skin cancer in the family.

However, it’s recommended to take note that everyone, no matter what skin type, is equally susceptible to an eye injury.

Health effects of UV radiation

Depletion of the Ozone layer reduces our natural protection from damaging UV (UV) radiation. This page provides an overview of the most significant health risks that result from UV radiation exposure. The risks are easily understood and taken steps to minimize the risk of developing sun-related health issues.

Skin Cancer

Every year, more cases of skin cancer are discovered in the U.S. than new cases of prostate, breast, or lung cancer, as well as colon cancer combined. In the course of their lives about one-in-five Americans will be diagnosed with skin cancer. One American dies of skin cancer every hour. Skin cancer is more likely to develop from not being protected from UV radiation exposure.

Melanoma

Melanoma, the most serious form of skin cancer, is currently one of the most prevalent cancers in young adults and adolescents aged 15 to 29. While melanoma accounts for only 3 percent of all skin cancers, however, it accounts for over 75 percent of skin cancer-related deaths. UV exposure and sunburns especially in childhood are the most likely risk factors. Some melanomas are due to sun exposure but not all. Other possible factors include genetic or immune system deficiencies.

Nonmelanoma Skin Cancers

Non-melanoma skin cancers aren’t as fatal as melanomas. But, they could spread when left untreated, leading to an appearance and health issues. There are two major kinds of nonmelanoma skin cancers such as squamous and basal cell carcinomas. If caught and treated early the two types of cancer aren’t always fatal.

Basal cell carcinomas can be frequently found in skin cancers. They usually appear as fleshy, small bumps or nodules around the neck and head however, they can also be found in other areas of the body. Basal cell carcinoma progresses slowly and is rarely spread to other parts of the body. It is, however, able to penetrate the bone and cause considerable damage.

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

Age-related Premature Aging and Skin Damage

Other skin disorders caused by UV exposure include actinic keratoses as well as premature aging of the skin. Actinic Keratoses are skin lesions that occur on body parts that are exposed to UV. The hands, face forearms, and “V” of the neck are most susceptible to this type of lesion. Actinic keratoses are not necessarily premalignant and can be a risk factor in cancer of the squamous cells. If you notice bumpy, reddish, or rough-textured growths, get immediate medical care.

Premature aging can also result from prolonged sun exposure. This can lead to skin becoming thicker, wrinkled, and more leathery with time. Because it is gradual with the majority of cases manifesting many years after the majority of a person’s sun exposure and premature aging is usually thought of as a natural regular part of getting older. However, 90% of visible skin changes often as a result of aging can be caused by the sun. When you protect yourself from UV radiation, most premature skin aging is possible to avoid.

Cataracts and other eye damage

Cataracts are a form of eye damage in which the loss of transparency within the lens of the eye can cloud vision. If untreated cataracts could lead to blindness. Research has proven that certain cataracts may be caused by UV radiation. Although curable with the latest eye surgery techniques cataracts can affect the eyesight of millions of Americans and cost billions of dollars in medical costs every year.

Other forms of eye damage include the pterygium (tissue growth that may block vision) and skin cancer around the eyes, and damage to the macula (the part of the retina where vision is the most intense). Eye protection is a great way to prevent any of these concerns. Find glasses, sunglasses, or contact lenses, if you wear them, that offer 100% UV protection.

Immune Suppression

Researchers have discovered that exposure to UV radiation can cause a decrease in the function of the immune system and the skin’s natural defenses. The skin’s normal defenses allow it to protect itself from infections and cancers. Exposure to UV radiation may cause the skin to be less able to resist these invaders.

A shirt, hat, and sunscreen are a must, and be sure you seek shade.

Beachgoers should know that white sand and other bright surfaces reflect UV and can double UV exposure.
EXTREME11+Protection against sun damage is needed. If you need to be outside during midday hours between 10 am. and 4 p.m., take steps to reduce sun exposure.

Easy steps to avoid sun-related diseases

You can reduce your chances of contracting sun-related illnesses by taking a few simple steps. These are the steps you can take to reduce your chance of getting sun-related ailments:

  • Limit your time in the sun between the hours of 10 a.m. and 4:00 p.m.
  • If possible, seek shade.
  • Make sure you use a broad spectrum sunscreen with a Sun Protection Factor (SPF) of at least 30.
  • Make sure you wear a wide-brimmed hat. And If you can, wear tightly-woven and full-length clothes.
  • Wear UV-protective sunglasses.
  • Avoid tanning salons, sunlamps, and sunlamps.
  • Watch for the UV Index daily.

You should take precautions in order to avoid excessive exposure to sunlight. You must be especially careful to follow the UV Index recommendations when levels are high to moderate. Keep an eye out for UV Index reports in your local newspapers and on television.
