ScienceDaily (May 31, 2011) — Children who are bullies or have conduct
problems at school are more likely to be sleepy during the day according to U
niversity of Michigan Medical School researchers.
Researchers looked at elementary school students in the Ypsilanti, Michigan
public schools who had exhibited conduct problems like bullying or
discipline referrals and found that there was a two-fold higher risk for symptoms
of sleep-disordered breathing, particularly daytime sleepiness among these
students. The study was published in the journal Sleep Medicine.
