The Unlikely Power of a Hug: How Touch Can Save Lives and Boost Wellbeing
In a truly extraordinary and potentially life-saving act, 35-year-old Nathan Newby faced down a would-be terrorist in 2023. Instead of resorting to aggression, Newby chose an approach that might seem counterintuitive: a hug. He encountered Mohammad Farooq, who was planning to detonate a bomb at St James’s Hospital in Leeds with the explicit aim of “killing as many nurses as possible.” Newby, who is now set to be awarded the George Medal for his remarkable bravery, initiated a conversation with Farooq, noticing his agitated state. His intention was simply to “cheer him up.”
The situation escalated when Farooq confessed to carrying a bomb in his bag. Rather than fleeing or confronting him violently, Newby attempted to de-escalate the situation through dialogue. He recounted that Farooq had requested a hug multiple times, to which Newby readily agreed. Following the embrace, Farooq urged Newby to “phone the police before I change my mind.” This simple act of human connection, a hug, appears to have averted a catastrophic tragedy. Farooq has since been convicted of preparing acts of terrorism and received a life sentence with a minimum of 37 years.
This extreme example powerfully illustrates the profound impact of human touch, even between strangers, in the most challenging circumstances. Touch is not merely a superficial gesture; it is a fundamental human requirement with a wealth of scientific research supporting its numerous benefits.
The Science Behind the Embrace: How Hugs Affect Our Brains and Bodies
Experts suggest that the innate human drive to cuddle may stem from our primate ancestors. Anyone familiar with nature documentaries will have observed apes and monkeys engaging in mutual grooming and stroking as a crucial method of social bonding.
Physiologically, a hug stimulates C-tactile afferent fibres, a specific type of nerve receptor in the skin that is particularly sensitive to light touch delivered at a speed of three to five centimetres per second. This stimulation activates the parasympathetic nervous system, which is responsible for the body’s “rest and digest” response. Crucially, this process triggers the release of oxytocin, often referred to as the “bonding hormone,” alongside other mood-boosting endorphins.
Dr. Michael Swift, founder of Swift Psychology and a spokesperson for the British Psychological Society, explains that “touch has a direct line to the brain’s calming system.” As these nerve fibres transmit signals to brain regions associated with emotion and safety, he elaborates, “a hug can feel soothing almost instantly, rather than being something we have to ‘think’ our way into.”
The Nuances of Touch: Duration and Relationship Matter
It’s important to acknowledge that not all touch elicits the same response. An accidental nudge from a fellow commuter, for instance, will not trigger the same physiological and emotional benefits as more deliberate and meaningful contact. Dr. Ravi Lukha, medical director at Bupa, highlights that the duration of a hug also plays a significant role in its potential health advantages.
- Ten-second hugs: These can contribute to increased alertness, bolster the body’s ability to combat infections, and reduce the likelihood of experiencing depressive feelings.
- Twenty-second hugs: A hug of this extended duration, Dr. Lukha notes, can offer particular benefits for cardiovascular health, including a reduction in stress levels and blood pressure.
Touch from Cradle to Grave: Lifelong Benefits of Physical Connection
The positive impact of touch begins from the earliest stages of life. “From early life onwards, consistent, warm touch helps build a sense of security,” states Dr. Swift. From birth, skin-to-skin contact, typically with a parent, plays a vital role in regulating a newborn’s heart rate, breathing, and body temperature, and has even been linked to a decrease in infant crying.
As adults, touch continues to serve as a powerful non-verbal cue for trust and reassurance, particularly during periods of uncertainty or distress. A well-known 2006 study from the University of Virginia demonstrated that women experiencing stress reported immediate relief when holding their partner’s hand. More recent research, conducted in 2022 by German scientists, analysed 36 young couples and found that women who had hugged their male partners before undertaking a stress-inducing test exhibited a smaller rise in the stress hormone cortisol compared to those who did not hug.
Indeed, the advantages of touch are often amplified when there is a positive relationship with the person providing the contact. However, intriguing research from UCL in 2017 suggested that even “slow, gentle stroking by a stranger” can mitigate feelings of social exclusion following rejection.
Boosting Immunity and Combating Stress: The Far-Reaching Health Impacts
Emerging evidence also points towards hugging’s potential to strengthen the immune system. A study by scientists at Carnegie Mellon University in Pittsburgh discovered that individuals who engaged in regular hugging in the two weeks prior to being exposed to the common cold virus were less susceptible to infection. Furthermore, their cold symptoms were less severe, and they experienced a quicker recovery.
A longitudinal study from 2021, which tracked older American adults over an extended period, found a correlation between higher reported instances of hugging and touch from loved ones and a reduced likelihood of developing chronic inflammation later in life.
Conversely, a lack of physical contact and hugging has been associated with elevated physiological stress, marked by increased levels of the hormone cortisol. The COVID-19 lockdowns, during which contact with anyone outside one’s immediate household was strictly prohibited, brought concepts like “touch deprivation” and “skin hunger” into sharp focus for many.
The Modern Dilemma: A Growing “Crisis of Touch”
Even before the pandemic, concerns were being raised about a “crisis of touch.” Our increasing reliance on digital interactions means that in-person contact and conversations are often being replaced by endless scrolling. This trend has been significantly exacerbated since the onset of COVID-19, with a lifestyle mediated through screens leaving many feeling isolated and starved of physical connection.
In response to this growing void, a range of commercial services have emerged to attempt to fill the gap. The first “cuddle cafes” opened in Japan in 2012, offering patrons the opportunity to pay for the experience of hugging, holding hands, or even napping alongside a staff member in a non-judgmental environment. This trend has since spread to the United States, and even within the United Kingdom, individuals can access the services of cuddle therapists who offer restorative platonic touch or facilitate group cuddle sessions.
While such offerings might initially seem unusual, they underscore a fundamental human need. Perhaps, in our increasingly disconnected world, embracing the simple, yet powerful, act of a hug is something we could all benefit from.
