Ruby, Karina, Miguel, and Albert Melatonin is a hormone released in your brain that contributes in regulating your sleeping cycle. Melatonin is produced in the pineal gland (beneath the center of the brain) and becomes active in the dark. This hormone targets your brain, for it contributes into regulating your sleeping cycle. Melatonin is usually released in the dark, because it regulates your sleeping cycles, also known as “circadian rhythms” Serotonin is the neurotransmitter that comes from the amino acid tryptophan., inside the pineal gland. Serotonin helps with the control of melatonin being released. Melatonin is regulates your “day and night cycle” by regulating your sleeping. This hormone plays an important role in healing and anti-oxidant protection. Melatonin affects the sex hormone as well, and the release of gonadoltrophic hormones (protein hormones secreted by the anterior pituitary gland, placenta. It also stimulates the gonads and controls much of reproductive activity). Melatonin may also prevent prostate and breast cancer as well. Melatonin has been shown to have a role in your mood, reproduction, tumor growth, and as an antioxidant. The most common cause of hypersecretion occurring with melatonin is a growth in the pineal gland, which is usually a tumor growing. When this occurs, a change in your sleeping cycle will happen. Insomnia and depression are the most known diseases that happen with hypersecretion. Treatments for hypersecretion or a scarce amount of melatonin reproduction include taking melatonin tablets, capsules, applying cream, and lozenges. At the moment, there isn’t a certain dose for melatonin takings. Different people will have a various amount of effects to the dosages. Lower doses seem to work better, while higher ones can cause anxiety. However, along with taking melatonin supplements, there comes side effects, which include: - Drowsiness. - Lower body temperature. -Vivid dreams. -Fidgeting, anxiety. -Small changes in blood pressure. Melatonin is used for sleeping problems, treating jet lag, headaches, to decrease the symptoms of those that are trying to quit smoking, reduce anxiety before going into surgery, low blood platelets, decrease sunburns when using the cream.
