Dr. Joseph Mercola believes the timing of your sleep affects its quality. Dr. Mercola says, "The more hours that you can sleep before midnight, the better off you will be." He cites a study published in the Lancet (a respected medical journal in Great Britain) indicating chronic sleep loss produces serious symptoms, such as the effects of aging and the early stages of diabetes (including age-related insulin resistance and memory loss).
