Bedtime linked to behavioral problems
Print Edition
Children who go to bed at irregular hours are more likely to have behavioral problems, according to a new study.
The research, which appeared in the US journal Pediatrics, found that lifelong problems could result from erratic childhood bedtimes, but that the effects could be reversed with implementation of a schedule.
“Not having fixed bedtimes, accompanied by a constant sense of flux, induces a state of body and mind akin to jet lag,” said Yvonne Kelly of the University College London.
Inconsistent bedtimes can disrupt natural body rhythms and cause sleep deprivation, impairing brain development and the ability to regulate some behaviors, the research showed.
“We know that early child development has profound influences on health and wellbeing across the life course,” Kelly said.
The British study analyzed the bedtime data of more than 10,000 children of ages three, five and seven, taking into account their behavioral problems as reported by teachers and mothers.
Hyperactivity, conduct issues, problems with peers and emotional difficulties were some of the conditions that were worse for children with irregular bedtimes.
Problems, however, only became more severe as children progressed through childhood. And those who adopted a more stable bedtime schedule demonstrated clear improvements in behavior.
Children with varying bedtimes or who went to bed after 9 pm were more likely to be from a socially disadvantaged background, a factor the study took into account.
