New study highlights the benefit of touch on mental and physical health

You might recognize the comforting feeling when someone offers you a hug at the end of a stressful day or strokes your shoulder when you’re feeling down. But the question remains: can touch really help you feel better, and does it matter who it’s from or how they touch you? To explore these questions, researchers from the Social Brain Lab at the Netherlands Institute for Neuroscience and the University Hospital Essen conducted a large-scale analysis of studies exploring touch interventions.

Benefits

Does touch truly improve someone’s wellbeing? It is an easy question to ask but more complicated to answer. Individual studies often only focus on specific instances and may contradict each other. Combining all these studies together for a large-scale analysis offers a clearer answer: yes, touch substantially improves both physical and mental wellbeing, for example via reduction of pain, anxiety, depression, and stress in adults. But in fact, those with physical or mental health problems (and therefore most in need of support) benefit even more from touch than healthy adults. “This is especially relevant considering how often touch interventions are overlooked” Packheiser, first author, adds.

“A key question of our study is to leverage the hundreds of individual studies out there to identify what type of touch works best,” adds Christian Keysers, director of the Social Brain Lab. “What if you don’t have a friend or partner close by to hug you? Would touch from a stranger or even a machine also help? And how often?. The study clearly shows that touch can indeed be optimized, but the most important factors are not necessarily those we suspect.”

Interestingly, the person touching you, how they touch you, and the duration of their touch doesn’t make a difference in terms of impact. A long-lasting massage by a therapist could therefore be just as effective as a quick hug offered by a friend. That is, until the frequency of the intervention is considered. The more often a touch intervention is offered, the greater the impact. A quick hug could therefore be even more impactful than a massage if it is offered more frequently.
