Although spiritual leaders would suggest that happiness comes from within, recent research is suggesting it may also come from without.
You know the feeling, when someone laughs uncontrollably, you just start laughing as well for no reason – simply because they are laughing. Well this type of reaction is known as ‘emotional contagion’ and may describe why some groups of people always seem to throw a great party while others seem to be able to spoil the mood every time. A group of dominant and happy people can actually make others in the room happier.
Thinking of friends of mine I know there are some who are constantly happy, and probably part of bond between us is the mutual benefits of happy emotional contagion. And of course, this is likely to result in a feedback loop where one happy person makes others happy, and others who are now happy make the original superstar even happier.
Just throwing it out there, it probably happens in reverse as well. Unhappiness rubs off too. Maybe try whistling in the streets and see if you can rub off some happiness.
