Apparently the average length of a hug between two people is 3 seconds. I recently read that researchers have discovered that when a hug lasts 20 seconds, there is a therapeutic effect on our body and mind. The reason-a ‘sincere’ hug produces a hormone called "oxytocin", also known as the love hormone. It has many benefits,helps us relax, feel safe and calm our anxieties. Free every time we have a person in our arms, we cradle a child, we cherish a dog or cat. Awww. Go give a hug!
