Many students try to cram school, work, activities, and socializing into too few hours, giving up sleep to manage the time deficit. Without proper rest and nutrition, you are susceptible to many different health problems, and existing medical conditions may be exacerbated. Psychologist and sleep expert, Dr. Brad Wolgast, Director of UD’s Center for Student Counseling & Student Development, reports that one of the most prevalent problems among young adults is poor sleep hygiene. “Sleep hygiene” refers to a series of healthy habits that can improve your ability to fall asleep, stay asleep, and get the rest you need.
