The Sun Is A Yellow Dwarf Star

Many people think that is it possible to achieve a “healthy tan,” but this thought has been proven wrong. Overexpose to UV-A and UV-B rays from the sun lead to premature aging of the skin, as well as the possible formation of skin cancer, know as melanoma. An appearance of a tan is actually a stage of burning and damage to the skin. Although a tan may be desirable to many, the fact remains that more people need to be educated on the dangers of the sun’s harmful rays, and the possible health complications of overexposure.

Go online and search the word “light”. What’s seen there? 4,270,000,000 results of a boat-load of definitions and websites and most likely the sun, right? Slightly exciting, but the real magic happens when you click on images. There are dazzling pictures of space, glowing fires, destructing lightning bolts, and vibrant smiles on faces. Instead of asking what is seen, ask what is felt. One may feel many emotions: happiness, amazement, curiosity and much more. Despite the feeling though, it’s impressing. Not impressing as in admiration or respect, although that can be felt, but as in making an everlasting mark.

A common challenge that most consumers will face is ineffective sun screens. This has caused many people to begin to experience an increase in cases of skin cancer. The problem is that research has confirmed these challenges. Yet, no one has utilized the latest technology to create a product that will protect consumers and is environmentally friendly. This proposal is focusing on how this kind of merchandise can be marketed to customers to address this underlying need. The expected outcome is that these strategies will help to redefine how firms are delivering this product to cliental.

Thesis: Many people do not use sun protection on a daily bases and are unaware of the health effects of sun exposure that can be easily preventive by using sun protection.

Light waves are a form of electromagnetic waves, which consist of patterns of electric and magnetic energy. The visible spectrum is only a small part of the electromagnetic spectrum-the

We benefit greatly the benefits of long distance communication, eating food from different parts of the countries without fear of spoilage, radiation treatment, and heating up food in a matter of minutes, and a myriad of other wonders all do the wonders of waves, be they sound waves as well as light waves. In this timeline, we will look at all of the different light waves, their history, and their benefits.

Dermatologists, physicists, and scientists conducted a workshop of UVA treatment, and the workshop’s findings are presented in the New England Journal of Medicine. A previous president of the American Academy of Dermatology wrote an article titled “UVA1 is Often A1” to discuss their findings. The workshop found that medium or high-dose UVA1 works well with morphea, urticarial pigmentosa, atopic dermatitis, dyshydrotic dermatitis, subacute pruigo, and systemic lupus erythematosus. These diseases are treated by UVA rays because the wavelength is longer, which means there is less energy delivered to the skin and the greater penetration of photons (Dahl, 2012). Dermatologists even use sunbeds with higher intensity than regular tanning beds in their offices. For example, Windsor Dermatology uses four different types of light therapy to treat the skin condition psoriasis. One type of light therapy is that of UVA. The anti-inflammatory properties of ultraviolet light aid in slowing the growth of psoriasis effected skin

“Indoor tanning under the age of 18 increases your risk of skin cancer by 75%”(Division of Cancer Prevention Ceanter). Over 10,000 people are expected to die this year from UV related causes. However, many people will disregard these facts and continue on with their harmful habits. There are many effects of artificial tanning and prolonged exposure to the sun. Many people have no idea about the risks of prolonged exposure to the sun, how dangerous artificial tanning actually is, or how radiation is not the only harmful trait of indoor tanning.

Whether swimming at the beach, picnicking at a park, or snowboarding in the mountains, our skin is continuously exposed to the sun’s ultraviolet rays as we go about our daily lives. The skin is beneficial as it protects our body from the outside elements including keeping out wind and water, dirt and dust, and all types of germs (Claybourne; 56). The topic of my experiment is to determine which SPF strength of sunscreen - SPF 30, SPF 50 or SPF 70 - is the most effective in blocking out the sun’s UV radiation. The purpose of this investigation is to observe, compare and determine whether the SPF label on sunscreen bottles are really effective in blocking out the amount of the sun’s UV rays, or if it is just a marketing gimmick to sell more products. This investigation benefits society because knowing which strength of SPF is the most effective in protecting against UV rays is useful to know when shopping for sunscreen, especially for those who spend a lot of time outdoors.

It does provide the obvious risks that come from UV tanning, but provides ways to prevent them while still being able to tan. The article also has a section on sunless tanning and how it could be the future of the UV protection, which a think is a key component of the source since many people don’t even consider it when wanting a natural, golden tan because of preusumptions that it makes the skin unnatural or

Several findings are made based on the results: UV radiation can cause cell death by inducing genetic mutation, which agree with Diepegen et al. (2012)’s finding regarding UV radiation’s destructive effect at a cellular level. Photoprotective agents can effectively prevent and reduce UV radiation induced damage to cells. Similar findings were made by Quatrano and Dinulos (2013), who indicated that sunscreen contains active ingredient that absorbs UV radiation ranging between 290-400 nm. This experiment proves that photoprotective agents with higher SPF values are more effective in absorbing UV radiation. Indicated by Green et al. (2011), they suggested that regular application of high SPF sunscreen will prevent melanoma.

The lab group conducted three separate experiments to test the effect of ultraviolet radiation on the survival of yeast cells. These experiments are significant because ultraviolet radiation can damage the DNA of human skin cells and eventually lead to skin cancer. The yeast cells were prepared and then exposed to UV for various increments of time. The first experiment was a comparison of a wild type strain versus an unknown type. The hypothesis was that if the unknown yeast has better adapted to ultraviolet radiation, more unknown cells would survive. The wild-type strain survived substantially more than the unknown. The second experiment introduced “protections.” The group covered the yeast samples with a thick black film or a sample of distilled water. More cells under the black film outlasted the cells under the distilled water. The third experiment covered the samples with a thinner, red film or a general sunscreen with SPF 70. More cells covered by the sunscreen lived than those under the red film.

Every hour at least one American will die of skin cancer caused by exposure to the sun. These statistics are alarming and most people are unaware that the sunshine that we all love so much is in fact a threat to our health and good looks. It is up to us to educate ourselves and our children on the harmful effects of sun exposure on the human body like premature aging, physical damage to the body, and cancerous diseases.

If asked what light is, one could say that it's one of the most basic
