Holding hands is a psychological and social action as much as it is a physical one. Director of the Touch Research Institute (TRI) at the University of Miami/Miller School of Medicine, Dr. Tiffany Field, stated that holding hands is one of the most powerful forms of touch because the skin is a sense organ that needs stimulation. In addition, in another study at the University of Virginia and the University of Wisconsin, neuroscientists studied the effect of holding hands with partners in stressful situations. The participants underwent the threat of electric shock and when holding hands with their significant other the levels of stress hormones like cortisol in their body decreased, so in other words “loving touch reassures.”. And in the same study, it was also shown that holding hands can promote health and wellbeing.
Moreover, a lot of studies — including one made at (UCLA) — show that human touch triggers the release of oxytocin (The love hormone) which increase the feeling of generosity, trust, and compassion. And it decreases the feelings of fear and anxiety. All in all; holding hands provides warmth, pressure relieves pain, and serves as a powerful statement.
