Ultraviolet

wavelength band range of 280nm to 320nm and is also a minor component of sunlight that is received on Earth. Like other forms of radiation, UV-B is damaging and can pose especially damaging effects on higher plant species. Targets that are sensitive to ultraviolet radiation include the DNA, membranes and proteins of plants with these components needing to be protected during any exposure of UV-B to allow for normal growth and development to occur (Jansen, et al., 1998). DNA repair and the secondary accumulation

and vital skill on the dangers of exposing their skin to ultraviolet radiations from the sun and some of the ways they avoid these radiations. The idea informing this strategy is so as to provide awareness as well as education about skin cancer from very young age so that children can acquire the right habits right from an early age. This strategy is a high priority because according to medical studies protection from the sun’s ultraviolet radiation is usually very important in childhood because

Some Ways That The Environment Affects Human Health? Air Pollution Air pollution is one obvious environmental health threat in OECD countries, contributing to a number of illnesses, such as asthma and in some cases leading to premature death. Of particular concern is the fact that children are more vulnerable to air pollution than adults, and increased rates of infant mortality have been recorded in highly polluted areas. Concerns about the impact of air pollution on health and the economy

Skin pigmentation is affected by the way that bodies absorb vitamin D from cholesterol. When a person is in the sun a lot, his or her body is exposed to ultraviolet B light; this is known to convert the sunlight into cholesterol, which then converts into vitamin D (Moalem 51). As a result, the amount of sun exposure that one gets can begin to make him or her a darker color; however, they are the ones who have a healthy level of cholesterol in their bodies. Hence, the darker skin is a compromise

Today, there are many diseases people have to deal with. Some of them are treatable and some of them are permanent. One of the visible autoimmune diseases is vitiligo. Vitiligo occurs when melanocytes die or stop producing the pigment that gives a skin, hair, and eyes color. When people have vitiligo the skin becomes whiter, and it usually occurs on skin on both sides of the body. The exact trigger is not known but it relates to immune system to attack, destroy the melanin-forming cells because

Skin is one of the main physical aspects which distinguishes humans from other species. Skin is an important feature because it has sweat glands, which regulate body temperature (Jablonski 2004). This was especially useful when homo sapiens first originated and roamed Africa and other tropical areas (Jablonski 2004). Perhaps the most interesting aspect of skin is the disparity of its color on different people in different parts of the world. Skin color is determined by melanin; if a person has more

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

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.
