Today is International Hug Day
International Hug Day is an annual holiday occurring on January 21. The holiday was founded on January 21, 1986 in Caro, Michigan, and has since spread to Canada, England, Australia, Germany and Poland.
A hug is a form of physical intimacy, not necessarily sexual, that usually involves closing or holding the arms around the neck or waist of another person. Hugging has been proven to have health benefits. One study has shown that hugs increase levels of oxytocin, and reduce blood pressure. Hugging is not particular to human beings, as there are many species of animals that engage in similar exchanges of warmth.
