A National Sleep Foundation survey carried out in Washington found that children who left electronic devices switched on whilst they slept had on average one hour less sleep a night.
Researchers found that technology had a direct impact on the amount of sleep achieved by the school kids (aged 6-17), with 72 per cent of them having at least one electronic device in their bedroom whist sleeping.
According to numerous studies, backlit electronics emit a light which can prevent people getting to sleep or staying asleep.
Dr Jill Creighton, Assistant Professor of Pediatrics at Stony Brook Children's Hospital advised that; "The burst of light from a phone can break a sleep cycle. The hour before bed should be a no-electronics zone."
Creighton suggests a traditional alarm clock should be used in place of a phone. She also recommends that electronic devices should be put away at least one hour before bedtime and be charged somewhere else other than the bedroom.
For those children who find it difficult to part from their technology, researchers suggest reducing screen time by at least 30 minutes a week, the suggested amount of time in front of a screen a day is 60 minutes. Researchers also recommended that for every 30 minutes that the kids spent glued to the screen, they should do another 30 minutes of exercise to combat it.
