For a detailed review of many different products for a better sleep, please read my post on Sleep Product Review: the Pros and Cons. I am a sleep expert, as well as a sleep scientist. You will find all that information and more on this page. Sleep science is the science that shows what causes and controls sleep, how to improve sleep, and what we need to be doing to sleep better. I'm not a doctor or a sleep researcher. But I'm a scientist, and a sleep expert. In fact, I was a Sleep Research Scientist. So you can read about all the research that shows sleep and sleep disorders are caused by the physical and chemical changes in the body when sleep is disrupted. I've published sleep-related articles on this site in the past. You can click on the links in this article to read them. Sleep is a major cause of injury and disability. I'm a licensed physical therapist and a sleep consultant. You can read about my services and sleep related injury.
