Psychotherapist Lucy Beresford explains we crave touch because it plays a fundamental role in our very existence. “Touch is part of our life from the very beginning, at birth, and conveys love and care without words,” she says. ... We can even feel bereft, as though we have lost our loved ones in some way,” she adds

Physical intimacy is sensual proximity or touching. It is an act or reaction, such as an expression of feelings (including close friendship, platonic love, romantic love or sexual attraction), between people. 

A hug or touch can result in the release of oxytocin hormone and in a reduction in stress hormones.

Physical contact from someone you care about can make you feel all kinds of things — excitement, arousal, peace. 

We immediately feel safe and secure when touched by a partner who loves us. There's a sense of calm stability.
