So be sure to wear sunscreen to protect yourself. But… what exactly are you protecting yourself against?
C. Ultraviolet (UV) Radiation
There are many different types of radiation. For example, visible light is everything you see; all the colors that are you are able to see. One step above visible light is ultraviolet radiation. There are 3 major types of ultraviolet radiation: UVA, UVB and UVC. The atmosphere usually absorbs UVC before it reaches the Earth. The ozone layer serves as a natural shield to many of the sun’s rays, however, now that the ozone layer is slowly depleting, more and more UV radiation can get through. UVB partially reaches the Earth, and UVA completely reaches the Earth. What does UV Index mean?
The ultraviolet index or UV Index is an international standard measurement of the strength of ultraviolet (UV) radiation from the sun at a particular place and time. Remind them that this number is always used by meteorologists in their weather

    Overexposure to sunlight can result in painful, red, sunburned skin. First degree burns results in peeling of the skin. Second degree burns can blister. UV rays in sunlight stimulate melanocytes to provide melanin. When melanin is exposed to UV light it oxidizes turning the skin dark. This darkening effect is the skins way of protecting itself against too much UV light. Sunburn damages the skin.

Long time overexposure can cause wrinkles, freckles, age spots, dilated blood…

    Welcome to the skin layers with our top layer called the Epidermis, the middle layer called the Dermis, and the bottom layer called the Subcutaneous Fat. The Epidermis guards the body and is full of Melanin which helps prevent sunburns, while the Dermis is stretchy, and stores a variety of sweat glands. However, MedlinePlus says that sunburned cells look much different than normal cells. Sun’s rays penetrate the outer skin, or the Epidermis, which destroys the Dermis, and results in the killing of skin cells. Also, the UV, UltraViolet, Rays from the sun are what cause the sunburns. Even when you are just tanning, the rays cause the melanin in your skin to become a darker color, while tanning, and sunburns, can reduce the melanin elastic, causing you to age prematurely.…

    Dangers Of Tanning Bed

    • 2104 Words
    • 9 Pages

    Hochman tells the story of a pediatrician named Jessica Lilley, who had developed malignant melanoma after years of using tanning beds. She did not realize the impact of using tanning beds until later on in her life when she was diagnosed with skin cancer. It is noted that "five to 10 minutes (depending on the equipment) in a tanning bed is roughly equivalent to a half-hour in the sun on a mid-July afternoon"(Hochman). This is a great comparison because it shows how much stronger tanning beds can be. Tanning beds are a huge risk, especially to those who are of a young age. According to the American Academy of Dermatology, "Nearly 70 percent of tanning salon patrons are Caucasian girls and women primarily between the ages of 16 and 29, and of the 28 million people who tan indoors every year, 2.3 million are teenagers." Similar to Jessica Lilley's experience, I also have a history of skin cancer. It is extremely important for me to prevent sunburn at all costs. Personally, getting sunburn on my back mutated the cells in a few of my moles, resulting in me needing to get them removed. I regularly visit the dermatologist to keep track of my moles. If a mole changes in shape, color, or size, it is highly recommended that the mole is biopsied and tested for cancer. It is very easy to develop skin cancer if the skin is not protected under harsh UV rays; thus, it is super important for people to regularly check their skin and protect it from the sun. Overall, many underage teenagers are unaware of the harsh effects of tanning beds, which is why it is so important that teens are educated early on in their…

    Many people who tan at younger ages have experienced wrinkled much faster than the average human being. Wrinkles is not the only problem one must worry about. Although you may be safe and cancer free at a young age, later in life you become more and more prone to the cancerous cells and diseases because of the exposure throughout one’s life. Tanning takes out the moisture out of your skin, causing wrinkles and dries out your skin leaving it dehydrated. Many tanners use lotion to prevent wrinkles and skin dehydration, but little do they know that certain lotions only make the U.V. light penetrate into the body more instead of hydrating the skin and preventing…
