Some pretty remarkable things happen while we sleep. Recent studies show that during sleep our brains clear out toxins that are associated with degenerative brain disorders such as Parkinson's and Alzheimer's. For those who snore, this “cleaning” process does not occur. Not only do snorers lose out on this opportunity, they crawl out of bed feeling exhausted and irritable. And that leads to increases in stress and anxiety, and also exacerbates any current mental health issues.
