Smiling makes me a happier person so I smile as much as I can – even on the computer (when I look up at the mirror and remember) When I get expression lines they’ll be happy lines.
I actually keep a mirror by my desk top computer. Its some company when I work on my own and I can also check my expression in it. See the photo of my desk mirror in How to avoid Tech Neck
I sometimes have an I dunno/lets wait and see expression too – but that makes downward lines.
The effect of smiling has been widely reported in the UK papers.
I’ve always believed it had an effect before I read the research and always smiled as much as possible for two reasons:
The research on smiling that I mentioned was a meta analysis of 138 pieces of research. The Study is called
“A half centuries worth of experimental findings does provide
considerable evidence that smiles, frowns, scowls and other facial movements can affect emotional experience in a variety of scenarios. “
The research doesn’t indicate why the smile affects my emotions.
I think its because other people react better to smiley people.
