We’ve always heard that going outside in the sun can be dangerous. The sun’s rays can cause sunburn, hurt our eyes, and even result in skin cancer if we get too much sun. This leads to parents putting hats on their children and slathering them with sun block whenever they head out to the beach. But are these harmful effects really as bad as they say? Are there any benefits to being out in the sun?
Sunlight isn’t made up of one type of light. The type of sunlight that affects our skin is called ultra-violet light, and there are three types of it: UVA, UVB, and UVC. Each affects us differently, although UVC rays are generally filtered out by the atmosphere and do not reach us.
When it comes to benefits, yes, there are some reasons why you should be out in the sun. Exposure to the sun’s rays in moderation is very beneficial to our bodies. It helps combat things like seasonal depression. Ever feel like you have no energy on a cloudy day or feel sad when it rains? This is due to a lack of sunlight, and in some people, it can be very serious.
The ultra-violet UVA rays also help our skin create vitamin D, a vitamin we need for growing and repairing bone tissue. If we don’t get enough of this vitamin, our bones can become quite brittle and weak. Some people don’t get enough vitamin D in their diet, so exposure to the sun is vital. Some studies have also shown that exposure to sunlight helps our bodies fight off various types of cancer, including skin cancer. Again, exposure must be kept to moderate amounts.
Finally, many people tan when exposed to moderate amounts of sunlight. This is actually a good thing. When the UVA rays stimulate the melanocytes in our skin, they produce more melanin, or brown pigment. This pigment protects our skin from the more harmful effects of the sun, allowing you to stay outside longer before you burn. Exposure to sunlight also makes the top skin layer thicken, which can help prevent scrapes and other damage.
However, there are dangers to being out in the sun. UVB rays can cause our skin to burn and peel. This peeling is actually the upper layer of skin dying, which is not healthy at all. It can also result in making you look older by aggravating wrinkles and thickening the skin.
Prolonged exposure to the sun can also result in permanent brown spots, called liver-spots, on our skin. However, these spots are not always harmless�"some are not liver-spots but rather basal cell carcinoma, a type of cancer. Long-term exposure to UVA and UVB rays can also result in malignant melanoma, another type of cancer that can rapidly spread throughout your body and become very serious with little warning.
Human growth hormone also known as somatotropin, is a protein that is naturally generated by the human body and acts as a chemical messenger. This hormone is responsible for a variety of vital functions in humans. Most vertebrates have a form of growth hormone, often abbreviated as GH, while the human version is often abbreviated as HGH for human growth hormone.
Somatotropin or HGH is quite large compared to most hormones, consisting of the full array of 191 amino acids. This hormone is produced by the somatotrope cells of the anterior pituitary gland, and its secretion into the blood is controlled by chemical signals from the nearby hypothalamus gland. Both the pituitary and hypothalamus glands are located in the middle of the brain.
Somatotropin is released into the blood stream in small amounts during sleep, and helps to control cellular repair, metabolism, muscle growth and the maintenance of normal brain function. It also helps to boost the immune system. Although the body ability to produce this growth hormone diminishes after ones adolescence it still plays an important role in one's health.
Although HGH is a very powerful protein, too much or too little of it can lead to a number of serious conditions. If a person is to be prescribed or take to much HGH this could result in a tumor in the pituitary gland, which can eventually lead to the condition known as acromegaly. Acromegaly symptoms include the thickening of digits, impinged nerves, blurred vision, and sometimes a form of diabetes. In this case one may opt to remove the tumor which can reverse the effect of acromegaly. However if the tumor occurred during childhood an abnormal amount of permanent growth may happen resulting in gigantism.
There is also a problem associated with too little HGH. A genetic mutation in the gene coding for the hormone, a problem with the chemical signal that controls HGH release, or any kind of structural malfunctions in the pituitary or hypothalamus glands can cause a lack of the hormone. If the hormone is deficient in childhood, a lack of overall growth will result, leading to a condition sometimes referred to as ?dwarfism?. If the deficiency begins during adulthood the symptoms often include fatigue, loss of muscle mass, and heart disease.
A synthetic form of the hormone and pre-curser forms are available today as a treatment for conditions resulting in a lack of the natural version. Many diseases are treated with grow hormone including AIDS patients to help them maintain weight in later stages of the disease. HGH is also used in the treatment of fibromyalgia, ulcerative colitis, Crohn's disease. A few other uses of the hormone include helping bodybuilders gain muscle, obese people lose weight, and elderly people reverse some of the effects of their age.
The purpose of this article is to inform you about the use of HGH and some of the synthetic and pre-cursors to HGH, which stimulate the pituitary gland to produce more HGH naturally. It is always best as with anything not to over due it, but to listen to the prescribed recommendations in using this product so that one can experience all the benefits of HGH and not the ill effects. As always pay attention to how your body feels and use HGH supplements to benefit your health and slow the aging process.
