Why Smiling Is Contagious

The remarkable thing about a smile is that when you give it to someone, it causes them to reciprocate by returning the smile, even when you are both using fake smiles.
 

Professor Ulf Dimberg at Uppsala University, Sweden, conducted an experiment that revealed how your unconscious mind exerts direct control of your facial muscles. Using equipment that picks up electrical signals from muscle fibres, he measured the facial muscle activity on 120 volunteers while they were exposed to pictures of both happy and angry faces. They were told to make frowning, smiling or expressionless faces in response to what they saw. Sometimes the face they were told to attempt was the opposite of what they saw - meeting a smile with a frown, or a frown with a smile. The results showed that the volunteers did not have total control over their facial muscles. While it was easy to frown back at a picture of an angry man, it was much more difficult to pull a smile. Even though volunteers were trying consciously to control their natural reactions, the twitching in their facial muscles told a different story - they were mirroring the expressions they were seeing, even when they were trying not to. 

Professor Ruth Campbell, from University College London, believes there is a 'mirror neuron' in the brain that triggers the part responsible for the recognition of faces and expressions and causes an instant mirroring reaction. In other words, whether we realise it or not, we automatically copy the facial expressions we see.
 

This is why regular smiling is important to have as a part of your body language repertoire, even when you don't feel like it, because smiling directly influences other people's attitudes and how they respond to you.

In over 30 years of studying the sales and negotiating process we have found that smiling at the appropriate time, such as during the opening stages of a negotiating situation where people are sizing each other up, produces a positive response on both sides of the table that gives more successful outcomes and higher sales ratios.

Science has proved that the more you smile, the more positive reactions others will give you.
