These are not just limited to <strong>sleep<\/strong>, but throughout the body. We could even stretch to say that <strong>sleep improvement<\/strong> plays a secondary role to the rest of the <strong>benefits<\/strong>.<\/p>\n<p style=\"text-align: justify;\"><strong>Melatonin<\/strong> is produced in the pineal gland, located deep in the <strong>brain<\/strong> and which was considered a possible receptacle for the soul in the early stages of neuroanatomy. There is melatonin in many species of animals and plants, which shows its basic importance in the metabolism of living beings.<\/p>\n<p style=\"text-align: justify;\">High concentrations of <strong>melatonin<\/strong> have been found in the retina, gastrointestinal tract, bone marrow, skin and other tissues. We can therefore deduce that it may have an influence on other physiological functions through local secretion and that, far from being just a <strong>sleeping aid<\/strong>, melatonin has multiple effects throughout the body, including:<\/p>\n<ul>\n<li style=\"text-align: justify;\">Regulating the different <strong>biological clocks<\/strong> of the body: biological neural clocks are adjusted in cycles more or less approximate to the duration of the day (22-26 hours), but the other daily cycles of the organism such as hepatic metabolism, renal, oxidative stress, body temperature and muscle toning have less accurate clocks so they require internal synchronization. That is why when we suffer jetlag, we\u2019re not only <strong>tired<\/strong>, but we feel almost sick &#8211; our body does not work properly.<\/li>\n<li style=\"text-align: justify;\">Control of <strong>oxidative stress<\/strong>: melatonin plays a key role in promoting the excellent health of mitochondria and an adequate control of oxidative stress.<\/li>\n<li style=\"text-align: justify;\">Prevention of <strong>dementia<\/strong>.<\/li>\n<li style=\"text-align: justify;\">Maintenance of the optimal neuronal state.<\/li>\n<li style=\"text-align: justify;\">Others&#8230;<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">The secretion of <strong>melatonin<\/strong> is influenced by external light through the optic nerve. This means nature allows us to synchronize with seasonal changes.<\/p>\n<figure id=\"attachment_970\" aria-describedby=\"caption-attachment-970\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-1057 size-large\" src=\"https:\/\/www.neolifesalud.com\/imagenes\/wp-content\/uploads\/2018\/05\/Ivan-1.png\" alt=\"Melatonin at high doses protects against cancer\" width=\"1024\" height=\"683\" \/><figcaption id=\"caption-attachment-970\" class=\"wp-caption-text\">Illustration 1- Free access on Pubmed central, courtesy of the <i>Journal of Clinical Sleep Medicine<\/i>).<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Each of us has a particular predisposition for <strong>melatonin<\/strong> secretion, the most frequent being the average that begins producing melatonin at around 8:00 in the evening and peaks about 2:00-3: 00 in the morning.<\/p>\n<figure id=\"attachment_970\" aria-describedby=\"caption-attachment-970\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"aligncenter wp-image-1057 size-large\" src=\"https:\/\/www.neolifesalud.com\/imagenes\/wp-content\/uploads\/2018\/05\/Ivan-21.png\" alt=\"Melatonin at high doses protects against cancer\" width=\"1024\" height=\"683\" \/><figcaption id=\"caption-attachment-970\" class=\"wp-caption-text\">Illustration 2- Example of a circadian melatonin whose secretion is too low.<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Quite often we find, when studying the secretion profile, a lack of coordination and insufficient secretion.<\/p>\n<p style=\"text-align: justify;\">These phase imbalances and deficits in the total effect of <strong>melatonin<\/strong> cause the appearance of chronobiotic rhythm alterations, imbalance and oxidative stress, etc.<\/p>\n<p style=\"text-align: justify;\">As we age, melatonin secretion drops in quality, resulting in imbalances of the circadian cycles and quantity thereof (figure attached).<\/p>\n<figure id=\"attachment_970\" aria-describedby=\"caption-attachment-970\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"aligncenter wp-image-1057 size-large\" src=\"https:\/\/www.neolifesalud.com\/imagenes\/wp-content\/uploads\/2018\/05\/Ivan-2.png\" alt=\"Melatonin at high doses protects against cancer\" width=\"1024\" height=\"683\" \/><figcaption id=\"caption-attachment-970\" class=\"wp-caption-text\">Illustration 3- Deterioration of melatonin secretion with aging.<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Although the doses normally found in <strong>supplements<\/strong> are around 2mg, these doses are too small to reach all tissues and serve the different purposes that melatonin has. In addition, in case of using an incorrect dose we can produce the opposite effect (insomnia or de-regulation), which is why taking melatonin supplements without measuring precisely normally only goes well for some people while others report <strong>insomnia<\/strong> and discomfort.<\/p>\n<p style=\"text-align: justify;\">At <a href=\"https:\/\/www.neolifesalud.com\/\"><strong>Neolife <\/strong><\/a>we advocate taking high doses of <strong>melatonin<\/strong>, which have the maximum beneficial effects, but at a personalized dose and at a specific time which will be most beneficial (and which will avoid side effects). For this reason, in collaboration with the <strong>International Institute of Melatonin<\/strong>, we conducted studies of melatonin profiles and oxidative stress to be able to prescribe melatonin and antioxidants properly.<\/p>\n<p style=\"text-align: justify;\"><strong>Age Management Medicine Group<\/strong><\/p>\n<p style=\"text-align: justify;\">Recently at the annual meeting of the AMMG in Orlando, Florida, attended by part of the <strong>Neolife<\/strong> medical team, results from several studies were presented which showed an <strong>antineoplastic<\/strong> effect from high doses of melatonin. In this post we want to review some of the most important ideas that were presented:<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"text-align: justify;\">There is no such thing as &#8220;high doses&#8221; of melatonin. Melatonin has been shown to be extremely safe and toxic levels of it have not yet been shown. This does not mean that we can take high doses without conducting a previous study, as <u>even if we do not have to avoid the toxicity, we still need to pay attention to the balance of the system<\/u>.<\/li>\n<li style=\"text-align: justify;\">Exposure to blue spectrum light is the most related to the secretion of <strong>melatonin<\/strong>. To secrete melatonin, you do not need to sleep, you only need to be in the dark. Professor Ritter went on to say that light at night &#8220;is a drug&#8221; in relation to the harmful effects it has. This is of extreme importance as the secretion of melatonin and the preparation for an adequate night\u2019s rest begins hours before going to bed (normally at 08:00pm). Maintaining good <strong>sleep hygiene<\/strong> and adapting screens to avoid blue light is essential to preserve our melatonin secretion as long as possible.<\/li>\n<li style=\"text-align: justify;\">Melatonin and all its metabolites have a powerful effect by capturing free radicals, which are highly toxic and damage DNA, leading to degenerative, autoinflammatory and oncological diseases. It has been seen in different studies that there is a higher incidence of <strong>cancer<\/strong> in workers on night shift, or with alterations in the important hourly rhythms (many transoceanic journeys). In fact, <strong>light at night<\/strong> is included as a carcinogen by the World Health Organization.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<figure id=\"attachment_970\" aria-describedby=\"caption-attachment-970\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1057 size-large\" src=\"https:\/\/www.neolifesalud.com\/imagenes\/wp-content\/uploads\/2018\/05\/Ivan-4.png\" alt=\"Melatonin at high doses protects against cancer\" width=\"1024\" height=\"683\" \/><figcaption id=\"caption-attachment-970\" class=\"wp-caption-text\">Illustration 4- Professor Russel J.
