Those who prefer later bedtime appear to exhibit more antisocial behavior.
“A preference for evening activities and staying up late is related to behavior problem and is evident even in preteens. Staying up late contributes to lack of sleep and this,
in turn,
causes problems such as lack of control and attention regulation,
which are associated with antisocial behavior,
” said Dr. Elizabeth J. Susman.
Susman and her team did the research in 111 subjects between 8 to 13 years old.
The researchers found a number of factors were related to antisocial behavior in the study group,
particularly in the boys. For girls,
a preference for evening activities was associated with a higher chance of relational aggression or aggressive behavior towards their peers.
Boys who experienced prolonged high levels of cortisol(皮质醇) tended to have more behavior problems than their peers. The association was not true for girls,
however.
levels of cortisol peak in the morning upon awakening and are stable during the afternoon and evening hours.
