Small screens keep kids from sleeping
Children who use devices with small screens at night--such as smartphones or tablets--get less sleep than children who do not use such devices, according to a new study.
Scientists from the University of California, Berkeley School of Public Health analyzed data on more than 2,000 children in fourth through seventh grade. The data was collected from the Massachusetts Childhood Obesity Research Demonstration Study that was conducted from 2012 to 2013.
The researchers found that the children who had access to electronic devices with small screens got about 21 fewer minutes of sleep per night, when compared with the children who had no access to small-screened devices. Children in the former group also reported feeling more sleep deprived. In addition, the research showed that kids with TVs in their rooms averaged about 18 minutes fewer of sleep compared to those who didn't have TVs in their bedrooms. used small screens at bedtime got less sleep than children with TVs in their rooms--an average of 18 fewer minutes of sleep. The researchers also found that children who had televisions in their bedrooms got about 18 fewer minutes of sleep per night than children with no TVs in their room.
The study, published in the journal Pediatrics, provides more evidence that the use of electronic devices at bedtime may hinder children's quality of sleep, and that small-screened devices may be particularly harmful to good sleeping habits.
