Tanning beds are devices that give off ultraviolet radiation to make a cosmetic tan. They were first invented in 1978 by Friedrich Wolff. They are typically horizontal making it easier for people lay down in them. People are usually in there for about 8 to 15 minutes. They can be Shor 2 found at tanning salons and some people even have their own personal

Sunlight Fades Color Thesis: Because of Ultraviolet radiation from the sun, photodegradation occurs and color fades over time. Energy from the sun Measured in wavelengths in nanometers Size determines strength Three types of energy from the sun Infrared Radiation Visible Light Ultraviolet radiation Three kinds of UV radiation UVA Longest wavelength -- 320-400 nanometers Pros and Cons Not blocked by the ozone layer upper part of Earth’s atmosphere acts as a shield UVB Partially blocked by ozone

The largest organ of the human body is your skin. It is your body’s first line of defense against infections, injuries, heat, and sunlight. It also helps in controlling the temperature of your body and getting rid of the excess water and salt by sweating it out. Skin cancer is also known as cancer of the sun. Excessive amounts of ultra violet lights affect your skin in negative ways, possibly leading to Melanoma skin cancer. Melanoma is the most serious type of skin cancer there is and can often

or blonde hair are at increased risk, as are those with a personal or family history of skin cancer. Any competent campaign would focus on these particular groups. 3. Common misconceptions need to be removed. Many think using sunscreen prevents ultraviolet rays harming the skin and reduces any risks.

tacrolimus or pimecrolimus, which are used on small areas. There are also a treatment that is used as a combination medication and light therapy. The patient will need to take in or apply medication called psoralen. After that, the patient exposed to ultraviolet A or UVA light. The skin turns pink and more normal skin color started to appear. It takes six to 12 months. The risk is that the skin might have bad sunburn, blistering, itching, over darkening, or risk of skin cancer. Another option is surgery

older. There is not much you can do about these internal causes of aging, but there are external causes of aging skin that you can control to some extent. The number one external reason skin ages is exposure to the ultraviolet (UV) rays of direct sunlight over extended periods. Ultraviolet rays break down elastin and collagen and hamper the production of new collagen, which the skin naturally produces to repair the damage. Prolonged exposure to the sun also significantly increases the risk of skin

absorb UVA and UVB, avoid the sun from 10:00 a.m. to 4:00 p.m., when its rays are most intense, wear a wide-brimmed hat to keep ultraviolet rays off your face, stay in the shade, pay attention to reflection from water, sand, and snow, watch for news reports that give the UV index in your area (2015). A UV index reading of 2 or less means low danger from the sun’s ultraviolet rays for the average person, and examine your skin regularly for any new moles or changes in moles

VastuShastra is a 5000 years old Indian Vedic science which had laid down the guidelines for human beings so that they could live in peace in their own space. Even in great scriptures like Atharv Veda, Gita, MayamatamMansar, VishwakarmaPrakash, SamranganSutradhar, VastuRatnavali and Sthapatya Veda, VastuShastra is described broadly. The fundamental concepts of VastuShastra were laid odwn by Rishi-munis through their thorough research in this area. Some believe that because of the principle of VastuShastra

that plays a major role in causing skin cancer is the Ozone layer. It helps protect people from ultraviolet radiation. However, the ozone layer is shrinking and this is due to man-made products like sprays and combustion of cars that are emitted in the atmosphere. This process is allowing more ultraviolet penetration to the earth thus increasing risk of skin cancer (Bair, 1991, P. 367,368). Ultraviolet radiation are the chief causes for skin cancer because the UV radiation
