The 34-year-old royal admitted, 'I worry for you girls.'
Speaking with students from the Burlington Danes Academy, Samara Hackett-Valton and Sophie Crowder, both 15, William said he has real concerns over body image and how women are portrayed online.
'The touched-up pictures are not real,' he said. 'Don’t try to recreate them or think that’s what you’ve got to aim for. There’s a lot of fakeness online so don’t worry about that.'
William continued, 'That’s a lot. You must be aware of that, it’s a lot of pressure. There’s so many things going on. You’re going to be bamboozled.'
When asked for his advice to aid mental health, Prince William told the assembly of 250 students: 'Don’t spend all day online. Seriously, don’t. For your mental health, get outside, come away from the screen. By all means, be on a screen but don’t be on it all day because it will only bring you into another world. It’s important that you balance the time.'
The royal also touched on the importance of speaking about feelings.
'It’s really important for boys. We’re not very good at talking about our emotions and how we feel. Girls have got a little bit better, and boys, we’ve really got to work hard on being able to talk to friends, family, and trusted people about how we feel.'
