Why do people need a hug?

 An airport in New Zealand recently introduced a restriction on hugging time. 

Why do people need a hug?

People hug when greeting or saying farewell, mostly to show and express their feelings. Maybe they also hug because of their culture or habit, but it is true that hugs have positive effects phisically and psychologically.

A very scientific stimulation, such as light, slow strokingtriggers endorphons which induces calm & relaxed emotions. Hugs can also benefit our immune system. Scientists have found that huggers are less likely to catch colds than non-huggers.

Looking at this behaviour widely, not only humans but also monkeys and apes hug. We evolved. Do we do it for the same reasons? Maybe not, but nevertheless, hugs have a lot of positive effects. We may want to try it now! But be careful, hugging for too long can be stressful.

From these points, it is understandable that many people spend their time at an airport before saying good-bye, but it is possible that the airport rule is doing travellers a favour in minimising the stress of parting.
