# Why We Need Physical Contact Even as Adults
There is something profound about being embraced by someone at the moment we need it most. No words, no text messages, no video call – just warm human contact that can say more than a thousand words. And yet we live in an era where we are gradually giving up physical contact without realising what we are losing in the process. Why do we actually need physical contact as adults? And what happens to our bodies and minds when we don't get enough of it?
The answers are surprisingly well-supported by science and yet deeply human. Physical touch is not merely a pleasant addition to social life – it is a biological need rooted deep in our evolution. Just as we need to eat, sleep or breathe, we need to be touched and to touch others. This need does not disappear with age. On the contrary – in adulthood it takes on new dimensions, and its absence can have serious consequences for our health.

What happens in the body when someone touches us
Every hug or handshake is underpinned by a complex biochemical reaction. Oxytocin plays a key role – a hormone released during physical contact, often nicknamed the "love hormone" or "trust hormone". Oxytocin lowers cortisol levels – the stress hormone – slows the heart rate, and creates a sense of safety and calm. Research published in journals such as Psychological Science has repeatedly confirmed that people who regularly touch others – whether through hugging, massage, or simply a friendly pat on the shoulder – show lower levels of stress and anxiety.
Physical contact also affects the immune system. A 2015 study from Carnegie Mellon University found that people with greater social support involving physical touch were less susceptible to illness after exposure to viral infections. In other words, a hug literally strengthens the body's defences. This is no mere romantic notion – touch has a measurable impact on physical health.
Endorphins and serotonin are equally important; they are released during pleasant physical contact and contribute to an overall sense of wellbeing. The skin is the largest sensory organ of the human body and contains specialised nerve receptors – known as C-tactile fibres – that are sensitive to gentle, slow touch and communicate directly with brain centres associated with emotions. Scientists have described these fibres as specialised sensors for social touch, present in mammals and playing a key role in social behaviour.
It is no coincidence that massages, hugs, or even simply holding a stranger's hand in hospital can alleviate pain. Research in neuroscience shows that physical contact activates the same brain regions as emotional support, and can thus literally rewrite the way the brain processes unpleasant feelings.
Adulthood and touch deprivation – a silent epidemic
While the need for physical contact in children is widely recognised and respected – nobody doubts that babies need to be held – this need in adults is frequently overlooked or even stigmatised. An adult who longs for physical contact may be perceived as overly dependent or weak. This prejudice, however, is profoundly mistaken and can have serious consequences.
Psychologists speak of the phenomenon known as touch deprivation (or skin hunger) – a condition in which a person has long lacked sufficient physical contact with other people. This state is not merely unpleasant – it is demonstrably harmful. Research links touch deprivation to increased levels of loneliness, depression, anxiety disorders, and even physical complaints such as headaches and sleep disturbances.
The Covid-19 pandemic dramatically highlighted this issue. Millions of people around the world suddenly lost their everyday physical contact – hugs with friends, handshakes with colleagues, visits with loved ones. The effects manifested very quickly: surveys from 2020 and 2021 recorded a significant rise in feelings of loneliness, anxiety, and depression across age groups. Many people realised for the first time just how fundamental a role physical contact played in their lives – precisely because they had lost it.
Consider an everyday example: Jana is a woman in her forties living alone in a large city. She works from home, sees friends only occasionally, and her family lives far away. On the surface she leads a full life – she has a job, hobbies, and social media. Yet she feels strangely empty, sleeps poorly, and is troubled by a vague anxiety. It is only after a conversation with a psychologist that she realises weeks have passed without a single real hug or physical contact with someone close to her. This is not unusual – a growing number of people in modern society share a similar experience, as physical closeness becomes increasingly rare.
As American psychologist Matthew Hertenstein, who has long studied touch, wrote: "Touch is the first sense to develop in the womb, and the last to leave us before death. It is the foundation of human experience."
Different forms of physical contact and their benefits
Physical contact, of course, does not mean only romantic or sexual touching. The spectrum is far broader, and each of its forms brings specific benefits. A friendly hug activates oxytocin and strengthens a sense of belonging. A handshake or a pat on the shoulder signals trust and respect – it is no coincidence that people instinctively perceive these gestures as expressions of sincerity. Massage has demonstrably therapeutic effects on muscle tension, pain, and mental wellbeing.
Interestingly, physical contact benefits both parties – not only the person being touched, but also the person doing the touching. Research shows that stroking an animal, cuddling a child, or massaging a partner reduces stress and increases wellbeing in the "giver" of touch as well. This bidirectionality is fascinating and shows that physical contact is, by its very nature, a shared experience.
In the context of a healthy lifestyle, it is worth mentioning practices such as partner yoga, dancing, or contact sports, which naturally incorporate physical contact into physical activity. These forms of movement connect physical health with emotional wellbeing in ways that isolated exercise cannot fully replicate.
A mindful approach to physical contact also plays an important role. Modern wellness culture increasingly recognises therapeutic massage, craniosacral therapy, and various forms of bodywork as legitimate tools for mental health care. This is not a luxury – it is a response to a genuine need of the body and mind that all too often goes unmet in a fast-paced world.
Cultural norms also bear their share of responsibility. In Southern European or Latin American countries, physical contact in social interactions is far more common – friends greet each other with kisses on the cheek, and conversations are accompanied by touches of the hand. Research suggests that this cultural openness to physical contact may contribute to lower levels of loneliness and a stronger sense of community. In contrast, in cultures of Northern Europe or North America, where physical contact is more confined to intimate relationships, touch deprivation is a considerably more widespread problem.
Older people represent a particularly significant group in this regard. Seniors who live alone or in care homes receive very little physical contact – yet it is precisely in old age that its absence can accelerate cognitive decline, deepen depression, and worsen overall health. Volunteer programmes focused on visiting seniors or therapeutic animal interaction are therefore not merely pleasant activities – they are meaningful interventions with measurable health outcomes.
So how can we consciously incorporate more physical contact into everyday life? No dramatic changes are necessary. Simply lingering a few seconds longer in a hug with loved ones is a good start – research suggests that a hug lasting at least twenty seconds has a more pronounced physiological effect than a brief, formal gesture. Regular massage, whether professional or with a partner, is another natural approach. For those who live alone, cuddling a pet may offer a solution – contact with a domestic animal demonstrably reduces stress and fulfils part of the need for physical closeness. And last but not least – dance classes, group yoga, or contact sports offer a natural framework for physical contact in a safe and enjoyable environment.
We live in an age that offers unprecedented opportunities for digital connection. We are online constantly, communicating with people on the other side of the world, with access to more information than ever before. And yet – or perhaps precisely because of this – it is becoming increasingly clear that the fundamental human need for physical closeness remains irreplaceable. No emoji, no video call, no virtual reality can fully substitute for warm human touch. The body knows it. The brain knows it. And deep within ourselves, each of us knows it too – we simply need to be reminded.
