College students who pull 'all-nighters' and get no sleep more likely to have a lower GPA

"Sleep in college students is generally inadequate, irregular and of poor quality. As sleep quality and quantity decrease, academic performance worsens. The data collected in this study indicate that the use of a single night of total sleep deprivation is not an effective practice for achieving academic goals," said Pamela Thacher, PhD, of St. Lawrence University in Canton, New York, who authored the study.

The findings are based on interviews with 111 students at St. Lawrence University.

The amount of sleep a person gets affects his or her physical health, emotional well-being, mental abilities, productivity and performance. Recent studies associate lack of sleep with serious health problems such as an increased risk of depression, obesity, cardiovascular disease and diabetes.
