Native Americans served in World War I even though they were not citizens of the United States. In fact, it was not until after World War II in the 1965 passage of the Voting Rights Act that all states were required to allow Native Americans to vote on the same basis as any other American.
Overview. Melatonin is a hormone secreted by the pineal gland in the brain. It helps regulate other hormones and maintains the body's circadian rhythm. The circadian rhythm is an internal 24-hour clock that plays a critical role in when we fall asleep and when we wake up. When it is dark, your body produces more melatonin.
Works with the body's natural cycle to safely and gently promote sleep. All of us produce the hormone melatonin naturally in our brains. It helps set sleep and wake cycles in humans, animals, and even plants and fungi. The amount of melatonin your body produces varies throughout the day and is based on its exposure to light. Darkness makes the body produce more melatonin, which induces sleep, while light suppresses its production. We include melatonin in a handful of our products to help gently promote sleep.
