Hugs and touches at the biochemical level cause pleasant (warm, spiritual) sensations due to the release of a substance such as oxytocin from a person, which belongs to the "hormones of happiness". With regular cuddling, the person develops a sense of acceptance, security, calmness, and confidence. On a psychological level, hugs form a person's beliefs that he is loved, that nothing threatens him, that he will always be helped. And such attitudes form his positive emotional background. That is, a person who regularly receives hugs and touches: he feels pleasure, feels loved and considers himself protected. All of these factors have an extremely positive effect on the favorable development of psychological and emotional health.
So hug more often!
