Advantages and Disadvantages of Sunlight
Sunlight is considered to be one of the most essential sources of energy on earth. Without it, autotrophs cannot carry out photosynthesis to produce glucose for respiration. Food chains will be significantly affected as every organism interacts with each other to form a complex, interlocking ecosystem. However, on the other hand, while the importance of sunlight is always emphasised, its potential harm to human health often arouses public concerns. In this essay, the advantages and disadvantages of sunlight will be discussed to find out if sunlight is a blessing or a curse to human health.
Vitamins are needed in small amounts in order for our body to function properly. They are usually consumed in food but vitamin D in particular, can be obtained from the sun. A lack of vitamin D can lead to muscle weakness and tiredness, leading to growth retardation or rickets in children and osteomalacia in adults. (Holick, 2011) Also, vitamin D can facilitate the absorption of calcium from the small intestine to maintain calcium homeostasis. (Christakos et al., 2011) It is useful in strengthening bones to prevent osteoporosis in later life. Furthermore, it is found in a study that colon and breast cancers can be prevented if the intake of vitamin D3 is increased. (Ucsdnews, 2007) Breast cancer is currently the most common cancer in the UK (Cancer Research UK, 2015) and if people increase their intake of vitamin D from the sun, the risk of
Vitamin B12 is Part of coenzymes used in new cell synthesis; helps to maintain nerve cells. Vitamin A Helps maintain good vision (necessary for night vision), resistance to infections, and supports growth and repair of body tissues. Vitamin D is part of the bone-making and bone maintenance team. Regulates absorption of calcium and phosphorus for bone health.
2. Vitamin D- A group of steroids; resistant to heat, oxidation, acids, and bases; stored in liver, skin, brain, spleen, and bones. Promotes absorption of calcium and phosphorous; promotes development of teeth and bones. Sources: produces in skin exposed to ultraviolet light; in milk; egg yolk; fish liver oils; fortified foods. Excess: Diarrhea calcification of soft tissues, renal damage. Deficienceis: Rickets,bone decalcification and weakening.
receiving an appropriate amount of calcium and vitamin D may be able to assist in lowering the risk of colon cancer.
Boosting your immune system,Vitamin D helps your body regulate the absorption of your calcium and phosphorus.
Vitamin D plays a critical role in many normal bodily functions as well as fighting against a wide number of health barriers. In an article by Jacqueline Kanopa, studies revealed that exposure to ultraviolet rays play a huge part in Vitamin D production, as well as having preventative effects on a disorder known as rickets; which leads to weakened bones due to lack of Vitamin D. This study supports the belief that exposure to UV rays play a critical role in Vitamin D production, and can be beneficial to those prone to certain
After looking at my analysis I was surprised because there I was lacking a lot of vitamins and minerals. Without minerals, our bodies wouldn’t be able to function which is why I was worried when I saw my reports. I was lacking vitamins such as Vitamin A where my intake was 392.53 mcg when it’s supposed to be at a high 700.00 mcg. I also barely had one of the most important vitamins in my body, Vitamin D. Being one of the most important vitamins to our body a Vitamin D deficiency is not healthy for the body in any way possible. Restraining from Vitamin D can cause problems such as fatigue, hair loss, depression, anxiety, bone weakness, and being prone to more diseases because your body isn’t fighting off the illnesses brought in from the outside. Aside from lacking vitamins, I’m also lacking a good number of minerals. The recommended amount of Calcium is about 1,000mgs, but my intake fell under 454mgs. Calcium is one of the most important minerals for the human body for the bones to grow stronger to prevent diseases such as osteoporosis, which is commonly found in women after the age of 50. Osteoporosis is a common disease where the bones become weak from loss of tissues around the bone structure. Not only is osteoporosis caused by lacking Calcium, but is also caused by Vitamin D deficiency, which are two things that my body lacks. If I don’t increase my vitamin/mineral intake it could be a huge determent to my
The body can synthesize vitamin D with the help of sunlight, from a precursor that the body makes from cholesterol. Osteoporosis is, " any failure to synthesize adequate vitamin D or obtain enough from foods sets the stage for a loss of calcium from the bones, which can result in fractures" (Whitney & Rolfes, 2013, p. 349). There are several common risk factors for developing osteoporosis, which lead to the condition of reduced bone density.
Vitamin D is essential for the human body to function there are various ways in which it benefits the body. Long ago it has been established that Vitamin D is important for healthy bones, this is because Vitamin D enables the absorption of vital minerals. These minerals
There’s always a new drug or supplement in the news or on the drugstore shelves that promises to work health miracles; but most end up forgotten because they don’t deliver on their promises. Vitamin D isn’t one of those. Vitamin D benefits your heart, your skin, your immune system, your mental health and can lower your risk of certain types of cancers, like breast, colorectal, prostate and ovarian. While you can take supplements to boost your Vitamin D levels, you can also try losing just 5% of your body weight, exercising and eating more fatty fish, like wild salmon.
3. Vitamin D promotes calcium absorption in the gut and maintains serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemia tetany. It is also needed for bone growth and bone remodeling by osteoblasts and osteoclasts. Without significant vitamin D bones can become brittle, thin, or misshapen. Vitamin D sufficiency rickets in children and osteomalacia in adults. Together with calcium and vitamin D also helps protect older adults form osteoporosis.
However, emerging studies suggest that the body uses vitamin D in many more ways nonrelated to bone health, too. Found in cells all over, different parts of the body use vitamin D in different ways. Muscles use vitamin D in order to move; moreover nerves require vitamin D in order to send messages between the brain and all other parts of the body [10]. Vitamin D also helps the immune system fight off invading bacteria and viruses, as well as provide protection for the nervous system [1]. More specifically, vitamin D has antioxidant effects that regulate the factors contributing to the growth of nervous tissue and increases cellular components. This aids the survival and function of neurons [3].
Vitamin intake is a commonly overlooked necessity in basic nutritional health. What most people do not know is that certain vitamin deficiencies can cause many health risks and problems. Many people believe that are getting all the vitamins they need from their diet, however most of the time they are not. One of the most common vitamin deficiencies is the low intake of Vitamin D. There are some vitamins that are produced by the body such as vitamin K; however some of the most important vitamins are not produced by the body. Vitamin D is one of the vitamins that our body needs to function correctly that is not naturally produced by the body. Vitamin D can be consumed through
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.
It has been proven that the Earth’s atmosphere blocks 98.7 percent of the sun’s UV rays. The other 2.3 percent that we are exposed to, have both beneficial and harmful effects. We do need to focus on the benefits, because we have way more of them. The only harm it does to our body is skin cancer, which by being more careful we can protect from. The
Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.
