"Chemicals get released into our brain and make us connect and want to be loving instead of fighting," he said.
The study interviewed 404 adult men and women, not all in a romantic relationship with their hugger, about conflicts, hug receipts, and their moods.
The answers suggested receiving a hug after a conflict associated with a smaller decrease in positive emotions and a smaller increase in negative emotions.

"Oxytocin, the love chemical, tends to act against or lessen any form of conflict we've got.
"Our brain which was set up millions of years ago is primarily designed for survival and looking for problems and dangers," he said.
For every one negative thing we say, it needs to be outweighed by five positive things to release oxytocin, Thorpe said.
