Go nude – be happy!
Are people who spend time naked in the company of others happier than those who don't? Scientists are reporting in the Journal of Happiness Studies that so-called "naturists" seem to be, though why remains unclear.
"Naturists have been saying this for some time," the lead researcher from the University of London in New Cross tells the Richmond and Twickenham Times.Still, he adds, "Little to no empirical research has investigated whether naturist activity actually makes us happier — or, just as importantly, why it makes us happier."
