A hug is a form of physical intimacy that usually involves closing or holding the arms around another person or group of persons. The hug is one of the most common human signs of love and affection, along with kissing.[1] Unlike some other forms of physical intimacy, it is practiced publicly and privately without stigma in many nations, religions and cultures, within families, and also across age and gender lines.
Sometimes, hugs are a romantic exchange. Hugs may also be exchanged as a sign of support and comfort. A hug can be a demonstration of affection and emotional warmth, sometimes arising out of joy or happiness at meeting someone.
Brief in most cases, it is used to show many levels of affection. It is not particular to human beings alone, as there are many species of animals that engage in similar exchanges of warmth.
Hugging has been proven to have health benefits. One study has shown that hugs increase levels of oxytocin, and reduce blood pressure.[2]
There are different variations of hugs. Prolonged hugging in a cozy, comfortable position is called cuddling[3]. Spooning is a cuddling position, a kind of hugging when both the hugger and the hugged persons face the same direction, i.e., the front of one person is in contact with the back of the second one.[4]
