According to Michelle Scott, a psychotherapist from The Recovery Centre Group (TRC), it’s very natural for us to act like this when the weather warms up: “Seasonally, summer is a time when we do feel safer because the days are long and we’re no longer hiding in our caves,” she tells Stylist.

But the easing of lockdown restrictions only bolsters this carefree attitude. Scott says that, after the 18 months we’ve had in the pandemic, this can actually be a good thing: “It’s a sign that you’re feeling hopeful and optimistic after holding your breath all this time. You’re feeling safer and more able to connect. It sounds like you’re no longer in fight or flight mode; your nervous system is returning to its normal state.”

Explaining why people go back to the teenage self, she adds: “It’s connecting back to the last time you felt like you were in a place of safety, and were more protected from adult life. Also, as teenagers, we feel opportunities are endless – we’re super human. You’re revisiting that natural feeling of being able to do anything, and having courage to go out into the world.”
