Screentime Expert Victoria Dunckley, MD

Dr. Dunckley is an integrative child, adolescent and adult psychiatrist. She is the author of Reset Your Child’s Brain.

She reports that interactive screentime can overstimulate and stress the developing nervous system, particularly in children with vulnerabilities.

Reversing the effects of electronic screentime:

“Screen media is unnaturally intense in sensory, cognitive, and psychological input. Designed to keep the user engaged, it tends to overstimulate the nervous system. The brain interprets all this stimulating input as a form of stress. This in turn triggers fight-or-flight reactions and a high state of arousal, making it difficult to wind down and sleep deeply.  


“My book details the science behind how electronics use causes the nervous system to malfunction, how that malfunction translates into different symptoms in different children.

Benefits of the Reset Program:

  • Normalizes hormones, enhances deep sleep, reduces “excitability” of brain cells, relieves over-stimulated reward (addiction) and sensory pathways 


  • Strengthens mood regulation and stress tolerance; increases capacity for eye contact, reciprocal conversation, and empathy; decreases stress, arguing and negotiating.”


Dr. Dunckley’s book Reset Your Child’s Brain: A Four-Week Plan to End Meltdowns, Raise Grades, and Boost Social Skills by Reversing the Effects of Electronic Screen-Time is an excellent resource.

Screentime expert Tripler Pell, MD

is a family physician, researcher and medical school teacher. She has a background in academic medicine, and enjoys translating current evidence into practical information to help families stay healthy. Dr. Pell is also an active mother of three.

Dr. Pell’s advice for other health providers:

“The most important thing health-care providers can do is to start asking the simple question, ‘How much time are you spending on a screen?’ as part of routine patient interactions.  This intake question should be as standard as asking about other aspects of health, like physical exercise, eating habits and substance use.


"A useful follow-up question to ask for problematic overuse would be, 'how much screentime is for work or for pleasure, and how much is lost time?’ 

"There is more work that needs to be done to understand the effects (particularly neurocognitive and inter-relational effects) better, but there is enough evidence to show that decreasing screentime, and emphasizing physical movement and real-time interpersonal relationships are the keys to healthy individuals and societies.”

With her children, Dr. Pell wrote Blinky and The Phone Fiasco:  A Family Guide to Screentime Limits. Second edition 2018, Indigo Press.

In this book Dr. Pell raises medical concerns about the health effects of digital media on our children’s health, and offers practical interventions.
