Hugging is free, and it really might make someone feel much less alone. According to The Daily Mail,
University College London researchers have found proof that “slow, gentle stroking by a stranger can reduce feelings of social exclusion after social rejection.” When blindfolded participants had their forearms touched slowly with a soft-bristled brush after being socially rejected they reported feeling better than those who received a fast touch or “neutral” touch from the brush. Senior study author, Dr. Katerina Fotopoulou explains, “Mammals have a well-recognized need for closeness and attachment. […] What is interesting [that we found is that] social support was optimally conveyed only by a simple, yes specific, instance of touch.”
Need a hug? LOL
