What do airport baggage screeners, students and basketball players have in common? They all need a good night's sleep. A study presented this week at the Annual Meeting of the Associated Professional Sleep Societies suggests basketbailers who get some extra z's are more likely to score in a game. (Stanford University) researchers monitored members of the school's men's basketball team during two weeks of regular sleep cycles and then two weeks with extra sleep. With extra sleep the athletes reported increased energy; faster sprint times; and better free-throw shooting. Another study found that college students who pull all-nighters to prepare for tests tend to have lower grade point averages than those who get regular sleep. And 2nd and 3rd graders with sleep disorders are more likely to receive bad grades in math, reading and writing, according to a study from Chappaqua Public Schools in New York.
