Electronics and Sleep Disturbance in Children: Wired and Tired
In this 2010 article published on her own site, Victoria Dunckley focuses specifically on sleep, describing evening electronics use as a pattern she associates with children being simultaneously overtired and wired — falling asleep late, sleeping restlessly, or waking unrefreshed. She points to blue-toned screen light suppressing melatonin release and to what she describes as a lingering stress-hormone response after screen sessions as two possible contributors, alongside a claim about non-thermal radiofrequency exposure that TechKids Foundation does not independently verify. Her practical recommendation is a trial period of removing screens, particularly in the hours before bed, to see whether a child's sleep and next-day mood change. TechKids Foundation includes this piece as an early, frequently cited statement of the sleep-specific strand of her broader screen-time argument, aimed at parents rather than clinicians.
