Learn to perceive your body again through interoception
We live in an era when we can monitor our heart rate through a wristwatch, measure blood oxygen levels using a phone, and track sleep through smart applications. And yet – paradoxically – fewer and fewer people truly perceive their body from within. Fewer and fewer people notice they are hungry until they are literally starving. Fewer and fewer people recognise they are stressed until it starts to hurt. This ability to perceive the internal signals of one's own organism has a name: interoception. And its gradual loss is one of the quiet health problems of the modern age.
Interoception comes from the Latin intero (inner) and capere (to catch, to grasp). It is the sense that informs us about what is happening inside our body – the heartbeat, breathing, the feeling of fullness in the stomach, muscle tension, temperature, pain, or an inner discomfort that we cannot easily name. It is therefore not only about physical sensations, but also about how we interpret these signals and how we respond to them. Neuroscientists today consider it one of the fundamental human senses, even though it is never taught in schools and most people have never heard of it.

Why We Stopped Listening to Our Body
The answer to this question is not simple, but its roots run deep into the way we live. Modern society teaches us from an early age to prioritise external stimuli over internal ones. Children are guided to eat according to a meal schedule, not when they are hungry. They are encouraged to suppress crying, fear, or fatigue. Adults then work according to fixed time schedules, ignore the body's signals of overload, and take painkillers before even asking what that pain is trying to tell them.
To this is added the omnipresent digital stimulation. Screens, notifications, social media, and a constant stream of information continuously redirect attention outward – towards content, towards other people, towards the virtual world. Attention is a limited resource and if we devote it all day to the external world, there is simply nothing left for the inner space. Research shows that the average person spends more than four hours a day with a phone in hand, and this time grows year by year. That is four hours during which attention is directed exclusively outward.
The consequences are more serious than they might appear. Research published in the scientific journal Biological Psychology showed that people with impaired interoception have a higher tendency towards anxiety, depression, and eating disorders. This is no coincidence. If we cannot correctly read our body's signals, we become disoriented – we do not know what we need, we do not know when we are overfull or exhausted, and we are unable to effectively regulate our emotions, because emotions are to a significant extent precisely bodily sensations.
Neuroscientist and founder of the Affective Neuroscience Laboratory Lisa Feldman Barrett repeatedly emphasises in her work that the brain constantly predicts what the body will need, and interoceptive signals are the key input for these predictions. If these signals are weak, distorted, or ignored, the brain works with incomplete data – and the result can be poor decisions, inappropriate emotional responses, or a chronic sense of inner uncertainty.
A good example from everyday life is the situation familiar to many working parents: they skip lunch all day, drink coffee instead of water, and forget to stretch, because they are simply "too busy." Only in the evening, when the children are asleep, do they sit down and suddenly do not know why they are irritable, why their head hurts, and why they feel so terrible. The body was sending signals all day – hunger, thirst, tension in the neck and shoulders – but the mind was elsewhere. This is not an exceptional situation. For millions of people, it is everyday reality.
How to Reawaken Interoception
The good news is that interoception is not a capacity that disappears forever. It is a skill, and like any skill, it can be trained. Science confirms this: the brain is plastic and interoceptive pathways can be strengthened through targeted practice. It need not involve anything complicated or time-consuming.
One of the most natural and accessible methods is mindfulness, or conscious presence. A study published in the journal Frontiers in Psychology confirmed that regular meditative practice focused on bodily sensations demonstrably improves interoceptive accuracy – that is, the ability to correctly perceive and interpret internal signals. The length of practice does not matter: even five minutes a day spent paying attention to one's breath, heartbeat, or the feeling in one's stomach can have a measurable effect.
Yoga, tai chi, and qigong work in a similar way – movement systems that intentionally connect movement with body awareness. They are not about performance or how the movement looks from the outside, but about how the body moves from within. It is precisely this inner perspective that distinguishes these practices from conventional fitness and what makes them powerful tools for restoring interoceptive awareness.
Another highly effective approach is working with the breath. Breath is the only bodily function that operates both automatically and consciously – and for this very reason it is an ideal bridge between unconscious bodily processes and the conscious mind. Simply stopping and consciously observing a few inhalations and exhalations activates the parasympathetic nervous system while simultaneously training the ability to turn attention inward. It is no coincidence that breathing techniques form the foundation of so many traditional healing systems – from Ayurveda and Tibetan medicine to modern psychotherapeutic approaches such as somatic experiencing.
As American psychiatrist Bessel van der Kolk wrote so aptly in his groundbreaking book The Body Keeps the Score: "For people to change, they need to become aware of their inner sensations and understand how their bodily feelings shape their emotions and thoughts."
Beyond meditation and movement, the environment in which we live also plays an important role. Nature has a demonstrable effect on the ability to perceive the body, because natural surroundings reduce the level of sensory overload and allow the nervous system to calm down. The Japanese practice of shinrin-yoku – forest bathing, that is, consciously spending time in a forest with all the senses engaged – is well documented in this regard. Research by Japanese scientists has shown that time spent in a forest lowers cortisol levels, regulates heart rate and blood pressure, and overall improves the ability to perceive bodily signals. This is not mysticism, but physiology.
Natural materials in everyday life work in a similar way. There is a reason why people feel different in a cotton t-shirt than in a synthetic one, why there is a difference between sleeping on a natural mattress and a foam one, why wood smells different from plastic. These sensory perceptions are part of the interoceptive system in a broader sense – they are information that the body receives and processes, whether we are aware of it or not. The conscious choice of natural materials and products that do not harm the body is therefore also a form of care for interoceptive health.
It is also interesting that diet and the manner of eating have a direct impact on interoception. The gut is today referred to by scientists as the "second brain" – it contains approximately 500 million nerve cells and produces over 90% of the body's serotonin. The gut-brain axis is one of the key interoceptive pathways, and if it is disrupted – for example by industrially processed foods, antibiotics, or chronic stress – this manifests not only as digestive problems, but also as mood changes, reduced ability to regulate emotions, and generally impaired interoceptive sensitivity. Caring for the gut microbiome through fermented foods, fibre, and minimally processed ingredients is therefore also caring for the ability to perceive one's own body.
It is important to mention one less-discussed aspect: interoception is not merely an individual matter, but also a social one. Research shows that people who grew up in environments where their physical and emotional needs were repeatedly ignored or punished tend to have more impaired interoceptive awareness. This means that restoring this capacity may, for many people, also involve deeper psychological work – body-focused therapy, building safe relationships, or gradually learning to trust one's own perceptions.
In any case, regardless of a particular person's starting point, one thing holds true: one can always begin, and one can begin with small steps. Pausing before lunch and taking a moment to notice whether one is truly hungry. Noticing how one feels after an hour spent on social media. Paying attention to where in the body one feels tension during an argument with a partner. These small moments of conscious attention are precisely what gradually builds a stronger interoceptive capacity.
To live in the body, not just in the head – this may sound like a cliché, but it is in fact one of the most pressing challenges of our time. The body is not merely a vehicle for the brain. It is an intelligent system that constantly communicates, warns, signals, and orients. Learning to listen to it again is not a luxury or an alternative trend – it is a return to something we have always had and that we stopped hearing in the noise of the modern world.
