Dr. Steven Stosny suggests that giving 6 full contact hugs a day for six seconds each massively reduces resentments and negativity. I like this idea.
So here is the catch, it needs to be for 6 seconds. Why 6 seconds? Because, it takes that long to really release the hormone of Oxytocin, the neurochemical that creates bonding effect and the release of resentment.
The other catch is that it is not going to feel natural to do this. That is okay. Do it any way. Whether it feels natural or not you still get the benefit. It will start to feel more natural over time. (see my blog about changing your brain for the neurology behind this strategy.
