The Pineal Gland secretes various hormones, two of which have been identified as Melatonin and Serotonin. Melatonin is secreted between 11 p.m. and 7 a.m. and Serotonin between 7 a.m. and 11 p.m. Both are anti-aging in nature and effect, especially Melatonin. Serotonin is a natural anti-depressant. Serotonin is secreted during sunlight hours. When melanated individuals (Black people) don?Äôt get enough sunlight, they naturally get depressed. This is due to lack of Serotonin. When melanated individuals don?Äôt get enough sleep during night- time, they prematurely age, the exception being the very creative people (e.g. Quaquaverals). People who get off into deep and vivid dreams secrete a lot of Melatonin.
