Some people are just not morning people. Whether it be because you like your sleep or because you do not get to bed until later, there are understandable excuses to why you hit that snooze button more than once.

Melatonin is a hormone that is naturally produced by the body in the pineal gland. This gland is approximately pea size and it is located in the brain. Melatonin is produced when our eyes start to sense darkness and regulates our sleep-wake cycle.

We all have the occasional night when we can’t seem to fall asleep. For many it lasts no longer than one or two nights, then regular sleep habits return, but for some the challenge to getting proper rest develops into something more. Insomnia is the inability to fall and/or to remain asleep for reasonable periods of time, and many people suffer from it one way or another.

Nearly 70% of American women report sleep problems at least some nights, according to a new poll commissioned by the National Sleep Foundation. Overall, 29% of the women surveyed say they use some type of sleeping aid at least a few nights a week.
