As someone who never leaves home without her Free Hugs sign and who has had amazing, deep connections & conversations with people all across the world of all ages, cultures and socio-economic backgrounds (including purposefully seeking out homeless and hugging them; remember we are all human) I agree emphatically! YES, Hugs boost our immune system and make us feel good. Every time we hug, we release oxytocin which as you said boosts the immune system, and lowers blood pressure as well as decrease stress. That little card board sign saved my life.
