Can faking a smile brighten our mood? This question has been part of a long-standing debate among psychology researchers about whether facial expressions influence our emotional experience, an idea known as the facial feedback hypothesis.

In a recent paper published in Nature Human Behaviour, an international collaboration of researchers led by Stanford research scientist Nicholas Coles found strong evidence that posed smiles can, in fact, make us happier.

Mr Coles told Newsday: 鈥淏y smiling the rest of your body will try to re-enact the sensation of happiness and create that full-blown bodily response.鈥�
