Sleep deprivation is common, with about 1 in 3 North American adults not getting the recommended seven hours (minimum) of sleep each night. When you're sleep deprived, you can't function at your best, and you may feel tired, have difficulty concentrating and remembering, struggle with emotions, and be at a greater risk for chronic diseases.
