Lowri Dowthwaite, a senior lecturer at the University of Central Lancashire, explains that it's in our biological make-up to seek out social contact – which is why hugging is so important to us.
"We are social creatures by nature and are hardwired to seek out contact with others, as this has been key to our survival. Our early ancestors relied on the support of their tribe for food, shelter and safety. Building relationships within the tribe was essential as being outcast was fatal," she told The Metro news.
"Physical contact allows us to bond closely with others. This attachment is vital from birth as, when we are born, we are dependent on a caregiver for food and safety. When we hug we tap into this primary attachment. Touching each other allows us to share warmth through our body and experience biochemical changes that further connect us to each other," she added.
"When we hug, we release a neurohormone called oxytocin – a powerful bonding hormone that makes us feel warm and fuzzy. Research has also found that the release of oxytocin is linked to increased trust and empathy, and it can also help you to cope during stressful times by nudging you to seek out social support," she explained.
Further research also shows that the release of oxytocin reduces feeling of pain – so giving someone a hug when they are suffering can really help.
Hugging, kissing, cuddling, and sexual intimacy can all trigger oxytocin production and it's also produced during childbirth and breastfeeding.
