(6) Although some ingredients are dangerous in sunscreen, sunscreen does way more good than bad. High factors of sunscreen prevent bad burns and give you a way lower risk of getting skin cancer, it is efficient and not expensive and keeps your skin healthy. Sunscreens limitations are little , of course it wears of and some UV rays do reach the skin, it is definitely better than wearing no sunscreen where your skin gets burnt and damaged and in extreme cases can get skin cancer like melanoma which is an extremely dangerous cancer. My concerns for the future of sunscreen is that people will add more and more chemicals to try make a stronger and better sunscreen and end up making a sunscreen that protects you from the sun but gives your skin new dangers just as bad as being exposed to the sun's UV
UV radiation is one of the most damaging factors that influences the health of the skin. It is more important in people than animals, however, due to their lack of furry covering and thus greater skin to sunlight exposure. Still, some animals with light pigmentation, thin fur, areas of bare skin or albinos will be at risk. Clinical studies have identified excessive sun exposure (and thus exposure to solar ultraviolet radiation) as a primary causative factor in various skin diseases including, premature ageing, inflammatory conditions, malignant and non-malignant tumours (Chang 2010; Schmitt 2011). This is due to a series of harmful biochemical reactions occurring in a process known as photoaging.
Doctors believe that exposure to UV rays of the sun, and tanning lamps/beds are the leading cause of melanoma. (2) If you are a young toddler and get a severe sunburn this may be a risk of skin cancer later in life. People in whom live in very warm places all year around such as Australia, Hawaii, and Florida have a larger chance of developing skin cancer, this is because their bodies are exposed to the sun daily. Also in some of the colder northern locations with the country having very light skinned people will also have a higher risk. Majority of the people that develop skin cancer are probably addicted to getting that perfect tan.
UV radiation is a form of energy from natural and artificial sunlight. Excess amounts can cause damage to DNA in the skin. Although some argue tanning is good for you because it helps form a “base tan” and the UV exposure time is controlled. The truth is, each time you lay in a tanning bed, it increases the risk of developing skin cancer
General purpose: To inform the public on the importance of using sun protection Specific purpose: To educate the public on the importance of protecting skin from the sun, and to encourage the use sun protection, such as sunscreen and hats, on a daily basis to prevent exposure from the sun that causes unwanted and harmful diseases that could have been preventive. Thesis statement: Many people do not use sun protection on a daily basis and are unaware of the dangers that can be easily preventive by using sun protection. I. Introduction A. Attention getting device: Using sun protection was about as important to me as……… In other words, it was the farthest thing from my mind.
Abstract: This essay talks about the radiation from sunshine and the effects that it bring to the human body. Admittedly, the sunshine the body some benefits, such as boosting the body’s supply of vitamin D and enhancing the mood. However, while people are receiving profits, they are also be influenced by some drawbacks. The long time exposure to sunlight brings people quite harmful effects and even destroy people’s skin. The UV radiation can be classified as UVA, UVB and UVC.
The large star that we call the Sun can be very helpful by providing us with vitamin D which enlightens our mood and keeps us optimists. Although in some cases sunlight exposure, especially too much of it can be very harmful to our health and skin. There are many different irritations that can be caused from too much sunlight, one of the most popular and common is sunburn. There was a survey and over one third of adults and up to 70% children had said that they have had sunburn in the past year (according to the cdc) 1. Sunburn is when your skin reddens, maybe swells up and sometimes even the blistering or peeling of the skin.
Irritant dermatitis is dose related. Allergic contact dermatitis occurs when the skin develops an allergic reaction after being exposed to a foreign substance. Because of the contact with allergic substation, the body release inflammatory chemicals. They can make the skin feel itchy and irritated. The time from the first contact to development of allergy reaction can vary from days, months or even years.
Both types of rays have photons and photons when released to the skin can cause free radicals which cause chemical reactions in nearby cells. This could easily cause you cancer and affect your DNA. UVA is one of the types of rays. UVA does, when exposed to the skin in a certain amount, can later on, have your skin age prematurely. They send off longer wavelengths which penetrates deeper into your skin.
