We’re used to hearing about the negative impact that using social media can have on girls – it can cause sleeplessness, low mood, depression and anxiety.

She joins Jenni to explain her theory and the research she commissioned from Cambridge University, along with Dr Anne-Lise Goddings, Clinical Lecturer at UCL Great Ormond Street Institute of Child Health.
