The sun is crucial to the survival of human species. It produces energy for us to grow food, get warmth, light and photosynthesis. Although there are many beneficial factors about the sun, there are some harmful things that it can do to life on earth. One of the harmfull things that the sun produces is a sunburn. A sunburn is the skin's defense to exposure to ultraviolet light (UV light). Often after a sunburn a person will experience redness, blistering, swelling headaches and dehydration . UV light is “ part of the electromagnetic (light) spectrum that reaches the earth from the sun.” There are two rays of UV light that are the main causes of sunburns, both of which are too small for the human eye to see. The first UV light is ultraviolet A (UVA). UVA prematurely ages the skin, causes wrinkling and can travel through glass. UVA is able to travel through glass because of it’s long wavelength (although the wave length is still not long enough for the human eye to see). The second light, UVB has a smaller wavelength and causes the actual burning of the skin. …show more content…
Sunscreen is a lotion (sometimes a spray or gel) that is a combination of several organic and non-organic ingredients. The non-organic ingredients like, zinc oxide or titanium oxide make the UV light reflect or bounce off of the skin whilst the organic ingredients such as “octyl methoxycinnamate (OMC) or oxybenzone” absorb the UV light and therefore take away the heat. Franz Greiter is considered to be the inventor of sunscreen after bringing it to a market in the mid 1960’s. Although, there have been earlier appearances of sunscreen found “Ancient Greeks used olive oil for this purpose, and ancient Egyptians used extracts of rice, jasmine, and lupine plants whose products are still used in skin care today.” (source
In World War II the soldiers used a jelly-like substance, called “red vet pet” to prevent themselves from the sun. Finally, Benjamin Green combined this substance with cocoa butter and coconut oil, which created the new line of Coppertone suntan cream. Coppertone has come a long way, to make their product better. As they changed the product, the advertisement changed over the years to appeal to the audience. Although both of these advertisements are being presented to get people to buy Coppertone, the modern day advertising is more appealing than 1944 advertisement; the modern day advertisement has a better focal point, action, general feeling and mood, selection of elements, and audience.

Tanning can be harsh to your skin. The light coming from the sun contains different wavelengths of ultra violet (UV) waves. The two types of waves concerned about are UVA rays and UVB rays. UVA rays are long waves that cause more damage than a UVB ray. UVA rays penetrate deeper into your skin and cause tanning (“The Dangers of”). More and more exposure to UVA rays can cause permanent damage ...
Tanning affects the human skin through ultraviolet radiation, part of the spectrum of light that omits from the sun to the surface of the earth. Ultraviolet A rays are the longer ultraviolet rays that are projected, and these rays penetrate deep into the layers of skin, causing a tanning effect (Harvard Women's Health Watch, 2). It does this by penetrating into the lower layers of skin, or the epidermis, and triggering cells known as melanocytes to make melanin, the brown pigment that causes tanning (Hyde, Patrice, MD, 1). They account for most of the ultraviolet components emitted by lamps in tanning beds, because they are associated with an almost immediate tanning effect (Brady, Mary S, 2). The shorter rays are ultraviolet B rays, and these rays only reach the outer superficial skin cell layer, also known as the epidermis (Harvard Women's Health Watch, 2). UVB rays, therefore, are the actual cause of sunbur...
Sun shine contain ultraviolet ray which can cause the sunburn or even skin cancer. According to Cancer Council in Australia, Australia has highest incident rate of skin cancer in the world. More than 430000 Australians are diagnosed with skin cancer each year. There are approximately 60 percent of people who have got skin cancer will survive greater than five years after they diagnosis (Cancer Council Australia, 2014). In order to protect people under the sun, the sun protective behaviour is significant necessary.
Over all, skin cancer is known to be a very common and dangerous cancer among the U.S.. Although there is no superior or particular cause known for it, it can be reduced by reducing radiation exposure from the sun and also tanning booths and beds. If not attempting to prevent it by staying out of the sun, and seeking not seeking shade and so forth, protection such as longer clothing garments that better cover the body as well as hats and sunglasses can help to eliminate direct exposure and reduce some of the damages that may occur. Certain amounts of sun light are healthy for the body as it provides vitamin- D which the body needs to maintain a healthy life style, though it is crucial not be over exposed as reverse side affects may occur, causing more harm than good.
Scientists have performed many different tests and studies to learn more about high exposure to UV. Close observation of cells have shown that sunlight, natural or artificial, can cause mutations or DNA damage in cells. This can lead to further damage which will then be passed down through generations. Another study scientists perform is on animals. Scientist will expose your typical lab animals to UV rays, and this test typically results in skin cancer on the animal. These studies have been performed with UVA, UVB, and UVC, and they have all proven
Every young girl or woman in America wants their image to look like a Barbie doll. This perfection includes being extremely skinny and extremely tan. In order to achieve this Barbie-like image women and men have been using tanning beds or spray tans to alter their appearance. Tanning beds can prove to be very harmful to a person’s health and can cause extremely dangerous medical conditions, including the most deadly type of cancer. However, fake tans can also be used in a positive way for some people who use them sparingly.
UV radiation causes significant damage to human skin, in the form of sunburns, aging, skin cancer, and nonmelanoma tumors. Human skin damage is primarily a result of tanning. The
I have chosen to do my essay on the largest organ of the body, skin. It has several functions vital to the survival of the body as I will discuss in the following paragraphs.
In 1960, Mustela create the first series of sun cream specifically for the delicate baby skin because it was a special need for protecting them against the sun (Mustela, 2015).
We need the sun for everything; food, transportation, education, and just to live. The sun negatively affects us in our daily lives because our skin is sensitive to the sun. This means that we are prone to burn. A way to protect our skin is with sunscreen. The short-term effect of not wearing sunscreen when exposed to the sun is you can get a painful rash or peeling of skin can occur. Long-term effects of not protecting yourself from the sun can be that it changes your DNA or gives you skin cancer. It changes your DNA by radiation smashing into you skin. The reason why this is so dangerous is because the DNA will now instruct the skin to fix itself because of the radiation, but the instructions would have been changed. It can also speed up
Probably the most commonly used word by your dermatologist, your beautician, your pharmacist or just the girl next door, and for a good reason. The sun’s damaging UV rays can single-handedly destroy your skin over time and in some cases even cause irreparable damage. It will burn your skin, dry it out, destroy collagen fibers and predispose you to cancer. Whether it’s a scorching sun or not, whether you are outdoors or not, sunscreen is an everyday must-wear. You have a choice.
