AOL: Although many people rely on a glass of wine to relax and fall asleep, even just one drink greatly diminishes the quality of that sleep, says neuroscientist Kristen Willeumier, PhD.

Even a few ounces of alcohol changes the basic structure of normal sleep. Having a drink to help you fall asleep is an ineffective sleep strategy that can lead to a multitude of sleep disturbances, including insomnia, excessive daytime sleepiness, and alterations in sleep architecture, says Dr. Willeumier.
