Free Essays on Melatonin

MELATONIN Melatonin is a hormone made by the pineal gland, located within your brain. Every day, as it gets later, the pineal gland goes to work by releasing increasing amounts of melatonin into your bloodstream. This hormone may play a role in many body processes. Your blood vessels, ovaries, gastrointestinal system and brain all have cells that are specially equipped to utilize melatonin. The main influence it has involves sleep. The time period in which the pineal gland releases the hormones coincides with the hours you typically sleep. It doesn’t cause you to fall asleep, but it initiates changes throughout your body that make you feel ready for sleep.
