The average length of a hug between two people is 3 seconds.
When a hug lasts 20 seconds, a therapeutic effect on the body and mind occurs.
The reason is that a sincere hug produces a hormone called "oxytocin", also known as the love hormone. This substance has many benefits for our physical and mental health, which helps us, among other things, to relax, to feel safe and calm our fears and anxiety.
Dr. David Spiegel of Stanford University, California, USA is a pioneer in observing the correlation between longevity and therapeutic support group for women with metastatic breast cancer. According to their research, the embrace as emotional support improved quality of life and reduced pain in many patients. But more revealing is that the pain has shown that not only was reduced by 50%, but patients lived twice (the women in the control group lived an average of 18.9 months, whereas the group receiving therapy support lived 36.6 months).
