Exploring the Profound Impact of Touch on Mental and Physical Well-being: Insights from a Comprehensive Study

New research underscores the positive impact of touch on both mental and physical health A recent comprehensive analysis conducted by researchers at the Netherlands Institute for Neuroscience sheds light on the various ways consensual touch can enhance an individual’s physical and mental well-being.

You may be familiar with the comforting sensation of receiving a hug after a stressful day or having your shoulder gently stroked when feeling down. However, the question remains: does touch truly have the power to uplift our spirits, and does the source of the touch or its manner matter? To delve into these inquiries, scientists from the Social Brain Lab at the Netherlands Institute for Neuroscience and the University Hospital Essen conducted an extensive examination of studies investigating touch interventions.

Benefits of Touch on Mental and Physical Health Does touch genuinely contribute to an individual’s overall well-being? While this question seems straightforward, its answer is multifaceted. Individual studies often focus on specific scenarios, sometimes yielding conflicting results. However, amalgamating these studies for a large-scale analysis provides a clearer insight: indeed, touch significantly enhances both physical and mental well-being by reducing pain, anxiety, depression, and stress in adults. Importantly, individuals with physical or mental health challenges, who arguably require support the most, derive even greater benefits from touch interventions than healthy adults. “This is particularly pertinent given the frequent oversight of touch interventions,” remarked Packheiser, the first author.

“A pivotal aspect of our study is to harness the wealth of individual studies to discern the most effective type of touch,” remarked Professor Keysers, director of the Social Brain Lab. “What if one lacks a nearby friend or partner to offer a hug? Could touch from a stranger or even a machine serve the same purpose? And with what frequency? The study clearly indicates that touch can indeed be optimized, although the most influential factors may not be those initially suspected.”

Interestingly, factors such as the identity of the person providing the touch, the manner in which it is administered, and its duration do not significantly impact its effectiveness. Thus, a prolonged massage by a therapist could be as beneficial as a brief hug from a friend. However, the frequency of touch interventions emerges as a crucial determinant of their impact. A brief hug, offered more frequently, may prove even more impactful than a longer massage.

Human vs. Non-human Touch The subsequent inquiry revolved around whether touch interventions necessitate human involvement at all. Surprisingly, interventions involving objects or robots can be equally effective in enhancing physical well-being. “Many individuals could benefit from improvements in well-being, possibly due to loneliness or clinical conditions. These findings suggest that a touch-robot or even a simple weighted blanket has the potential to aid such individuals,” elucidated last author Frédéric Michon. However, the benefits of robot and object interventions exhibit less efficacy in improving mental well-being. Consequently, mental health disorders like anxiety or depression may still necessitate human touch, “perhaps indicating the significance of an emotional element associated with touch,” as pointed out by Michon.

While the researchers harbored curiosity regarding human-animal contact, studies examining this aspect remain scarce. “It would be valuable to ascertain whether touch from an animal or pet could enhance well-being, and conversely, if they too derive benefits from it. Unfortunately, there is insufficient, or properly controlled, research to draw definitive conclusions on these matters,” clarified Michon.

Touch Interventions Across Different Age Groups Upon investigating the impact of touch on newborns, researchers discovered significant benefits derived from touch interventions. However, the identity of the individual administering the touch emerged as a crucial factor: touch administered by a parent yielded greater benefits compared to touch by a healthcare worker. “This finding holds significant implications,” remarked Packheiser. “In countries with high rates of premature births and associated mortality, the knowledge that a baby benefits more from the touch of their own parent offers a readily implementable form of support for the baby’s health.”

Due to a scarcity of studies, drawing conclusions about the impact of touch on children and teenagers proved challenging. “Large-scale studies like this not only aid in drawing broader conclusions but also pinpoint areas where research is lacking,” elucidated Michon. “We hope that our findings will guide future research to explore lesser-known questions. This encompasses animal touch, touch across various age groups, and within specific clinical settings such as autism, a category that has been relatively underexplored.”
