Patient holding packaging of Circadin, the brand name of the hormone melatonin. Melatonin is a hormone secreted by the pineal gland in the brain that controls the body's biological rhythm. It is secreted at night and induces sleep. It can be taken to prevent jetlag. In middle age, melatonin secretion drops off and may be responsible for ageing symptoms such as insomnia and irritability. | |
