The Science of Touch

Touch is one of the things that makes you human. Tactile communication is generally regarded as the first form of human communication, beginning in the womb and then remaining an important factor in human development throughout your lifespan. Touch is one of the primary ways humans communicate, and research shows that a simple touch effectively communicates multiple emotions (1). In fact, physical touch is such an effective communication tool that research has found it is effective in expressing emotions such as love, gratitude, and sympathy even between strangers (2). Touch can also induce physiological responses, activating the secretion of oxytocin (often referred to as the “love” or “hug” hormone) and even decreasing heart rate and blood pressure (3). Overall, giving and receiving regular physical touch is an important factor in overall well-being (4). 

Relationships and Health

Regular touch is one of the hallmarks of healthy social relationships and having strong relationships is directly associated with better health and well-being (5, 6). A systematic review of 63 clinical trials found that the strength of social bonds was the most direct factor associated with mental health outcomes (7). Other studies have found that initiating contact with those in your social circle strengthens your own emotional resolve, decreases depression risk, and that those with close social connections generally have better lifestyle (dietary and exercise) habits (8, 9). Furthermore, analysis of one of the longest and largest investigations into chronic disease provided evidence that you will likely have better heart health, an easier time managing weight, and a longer lifespan if you prioritize relationships (10). 

Embracing Well-Being 

The human brain is designed to respond to physical input, particularly human touch. That hit of oxytocin makes you feel good in the moment, and promotes long-term benefits. A touch can be healing and help ease stress, as it slows secretion of cortisol and activates your parasympathetic nervous system (your “rest and digest” system), slowing your heart rate and lowering blood pressure (11). A simple touch can also:
