Even though he’s the future king of England, Prince William engages with Great Britain’s youth in down-to-earth terms about relevant issues. Recently, the prince spoke about the connection between declining mental health and the online world. And his advice for better mental health is something we can all put into practice.

At a surprise visit to Burlington Danes Academy, where 250 kids gathered, ranging from 11 to 18 years old, Prince William joined YouTuber, Dan Howell, to talk about mental health, as well as practical ways to support it.

Mental health isn’t a new passion for Prince William. He, along with his wife, Kate Middleton and his brother, Prince Harry, began the Heads Together campaign, which “aims to change the national conversation on mental wellbeing,” and wants to end the stigma surrounding mental health.

In a culture that has long valued the “stiff upper lip”, Prince William especially encouraged boys  to talk about their feelings. “We’re not very good at talking about our emotions and how we feel”, Prince William confided, but he stressed the importance of these meaningful conversations to avoid mental health problems.

And for boys and girls alike, Prince William gave firm instructions: “Don’t send 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.”

This royal reminder can encourage everyone to minimize their online time, while inviting more “real life” experiences in.
