Scientists from the University of Otago (New Zealand) found that using gadgets and watching TV before bedtime encourages children to fall asleep later, but does not impair the quality of their overall night’s sleep. Research results It was published In JAMA Pediatrics.
The study involved 79 children, aged 11 to 14. Each subject was instructed to wear a body-worn camera on their chest for three hours before going to bed. In addition to the body camera, which recorded which devices the children used, a second infrared camera was placed in their bedrooms. The scientists used it to track the time spent in front of screens in bed.
Scientists who observed children for a week found that 99% of participants used electronic devices in the two hours before bed. More active or multitasking device use, such as playing games, was found to encourage participants to fall asleep later. The researchers also found that every 10 minutes of screen time shortened children’s nightly sleep by the same amount.
However, children compensated for late bedtime by waking up late. However, it has not been confirmed that blue light or interactive interaction with devices disrupts the structure of sleep and worsens its quality. According to scientists, the negative effect of screen time on sleep is primarily due to changes in the schedule.
