In this episode of the Celebrate Kids podcast, Dr. Kathy delves into the impact of smartphone use on children's mental health, particularly those under the age of 13. Citing a significant study published in the Journal for Human Development and Capabilities, she discusses how early smartphone exposure is linked to suicidal thoughts, emotional regulation issues, and lower self-worth, especially in girls. The study, which analyzed data from nearly 2 million individuals across 163 countries, highlights the detrimental effects of social media, sleep disruptions, cyberbullying, and strained family relationships associated with early smartphone use. Dr. Kathy emphasizes the importance of observing children's behaviors and interests to guide their development, advocating for mindful engagement and opportunities for discovery away from screens.
