We can all agree that being lonely is bad. But apparently, science shows it’s really, really bad. Indeed, being lonely is so dangerous to your health that its equivalent to smoking 15 cigarettes a day. And it gets worse: we’re in the middle of a loneliness epidemic, meaning that the health of millions is at risk.

In this episode of The Studies Show, Tom and Stuart ask two questions: is there actually a loneliness epidemic? And does it make sense to compare loneliness to something as bad for you as smoking cigarettes?
