Melatonin - useful The prescription of melatonin in children and adolescents has slowly increased over the past decade. The appropriateness of this has repeatedly been questioned in the press, since melatonin by Apoteket classed as hypnotics. In an article in the Swedish newspaper Svenska Dagbladet January 9, 2013 performed a known sleep physicians additionally claim that melatonin can interfere with sexual development if given to children. Both the doctor and the responsible medical editor has refused to deny this false rumor, although they have current references that show that they are wrong. Given all the parents who are unnecessarily worried and perhaps even stopped giving their children melatonin, I want this text to give my view of…show more content…
Others believe that it is a common sleep medicine, with all the risks of habituation associated with such. Others have read or heard that melatonin is a hormone produced in the pineal gland. While this is unfortunate because it evokes real hormones that can have dangerous side effects of overdose. But partly fills melatonin not all the criteria of a hormone, and it has many other very important effects - even quite vital since life on earth was dependent on oxygen. The Earth 's atmosphere was oxygen-free until around 2 billion years ago. When oxygen reacts with different molecules in a cell (oxidation) formed including so-called free radicals, which in excessive amounts can damage other important molecules in the cell. This process is called oxidative stress. To survive normally occurring oxidative stress, the oxygen dependent organism special enzymes and other light molecules, both known antioxidants that eliminate free radicals and other damaging oxidation. Even before the introduction of oxygen on Earth produced primitive light-dependent bacteria a substance that appeared to function as antioxidantium, namely, melatonin. Melatonin production was a prerequisite for their survival and later development of more complex organisms…show more content…
It is still the most important human antioxidantium, and it is produced in most cells of the body as protection against the free radicals that are constantly generated. This applies in particular cells that are exposed to environmental influences, that the eye, skin and the intestinal tract, but also cells with high oxygen consumption, as brain cells. Melatonin is different from dietary antioxidants - such as vitamins C and E vitamin - through its many breakdown products (metabolites) in several stages also seem antioxidant. This results in what has been called an anti-oxidative "cascade" and make melatonin highly effective even in low concentrations. (2) Only much later in the development of life on earth, melatonin molecule also received other tasks, such as being a messenger, sending signals to other cells via specific receptors on their surface. It is the property giving rise to the term hormone. Upon the discovery of melatonin in 1958, it was also in tallkottkörtlar of mammals were found there, and the long time it was thought that it was only in vertebrate tallkottkörtlar. This meant that the term hormone was close at hand. melatonin has many features that distinguish it from classical hormones
