Anxious children have problem sleeping, but only in school nights, Australian research seems to show. That is some indication of the impact of the schools on young minds.
Most childhood problems associated with sleeplessness, such as delays going to sleep, night-time fears and difficulty sleeping alone, gradually resolve themselves as the non-anxious child ages. But for some children, anxiety about a range of issues leading to difficulty sleeping or falling asleep, may persist and can eventually cause more serious problems later in life if left untreated.
Scientists from the Centre for Emotional Health at Macquarie University, Sydney found that one in five anxious children have insufficient sleep while one in three have difficulty falling asleep. Results from the study showed that children with anxiety disorders go to bed much later and had considerably less sleep compared to non-anxious children. Significantly, these sleep disturbances did not occur on weekends and appeared to be limited to school nights.
During the week, the researchers found that school-aged children with anxiety disorders slept 30 minutes less than non-anxious children. However, anxious children fell asleep quicker and were less awake on weekend nights.
Associate Professor Jennifer Hudson, who led the study, says that while 30 minutes less sleep per week night may initially seem small, the cumulative effect and its potential consequences on daytime performance may be significant.
"We know that school-aged children's sleep is crucial for their overall quality of life and that sleep problems are associated with a range of cognitive and emotional difficulties so it's important to resolve them as quickly as possible," she says.
"What these studies show us is how important it is to treat sleep-related problems in anxious children," says Hudson.
The children in the study ranged in age from seven to twelve years old, and the findings are published this month in the international journal, Behaviour Research and Therapy
