Know your fears and know what makes you feel safe! Why healing is only possible when we feel safe

What actually makes you ill? And what keeps you healthy? These questions sound simple – and if you really look into them, they almost always lead to the same place: the autonomic nervous system. And to two states that decide everything: Fear and safety. Everyone encounters people every day who function, who persevere, who try many things – and who still don’t really recover. Not because the therapy is wrong. But because a crucial step is missing: looking inwards. Getting to know your own fears. Knowing what feels safe to you. Because without this knowledge – and this is not a metaphor, this is neurobiology – the body cannot heal.

The autonomic nervous system – the silent conductor of your life

The autonomic nervous system regulates everything that happens in your body without conscious control: Heartbeat, breathing, digestion, immune defense, sleep, hormone release, inflammation regulation. It works around the clock – and it works automatically. But it is not untouchable. It reacts to everything you experience, think and feel. To every conflict, every loss, every uncertainty. To every fear.

It consists of two major branches: the sympathetic nervous system, the activation system – heartbeat high, muscles energized, digestion paused, brain in survival mode – and the parasympathetic nervous system, the system of regeneration, healing and rest. In a healthy life, the two alternate rhythmically. Tension and relaxation, performance and recovery, wakefulness and sleep. This interplay is called heart rate variability – and it is one of the most reliable indicators of true vitality.

The problem of our time is not that we activate the sympathetic nervous system. The problem is that it no longer switches off.

Fear as the real driver

When we talk about stress, most people think of work, time pressure, noise and excessive demands. All of that is true. But in most cases, there is something deeper underneath: fear. Fear of losing control. Fear of being judged by others. Fear of not being enough. Fear of illness, of loss, of loneliness. Fear that has perhaps been there for so long that it feels like normality.

From a neurobiological perspective, fear is one of the strongest activators of the sympathetic nervous system. It triggers the same cascade as a physical threat: cortisol rises, adrenaline circulates, the body mobilizes for fight or flight. Only this time the threat is not a lion, but a thought. A memory. An expectation. A feeling that can’t be named, but is constantly with us.

And here lies the real problem: a thought does not end. A memory cannot be run away from. An unconscious fear does not switch off the sympathetic nervous system when the external situation is over – because it does not come from outside. It comes from within. And as long as it remains unseen, the nervous system remains on alert.

Perhaps it is worth pausing at this point. Not to force answers, but to take an honest look.

A simple exercise: take a moment and ask yourself – what am I actually afraid of?

The answers are as individual as the people who carry them. And yet there are fears that run through almost all lives:

• Fear of failure
• Fear of losing a loved one
• Fear of illness and death
• Fear of rejection – not being liked or accepted
• Fear of not being good enough – as a mother, as a partner, at work, as a person
• Fear of losing control
• Fear of change and the unknown
• Fear of loneliness
• Fear of abandonment
• Fear of real closeness and vulnerability
• Fear of financial hardship and social decline
• Fear of conflict and your own anger
• Fear of being at the mercy of others
• Fear of being too much – or too little
• Fear of ageing and insignificance
• Fear of being forgotten
• Fear of the opinion of others and public exposure
• Fear of making mistakes – and being punished for them
• Fear of dependency and loss of autonomy
• Fear of your own body, pain and loss of control over your health
• Fear of silence – because things emerge in the silence that you would rather not feel
• Fear of the future and of a world that is changing too quickly
• Fear of losing your own identity
• Fear of disappointing your own parents – even as an adult
• Fear of disappointing or damaging your own children
• Fear of not belonging
• Fear of what others would think of you if they knew the truth

None of these fears make you weak. They all make you human.

And then the counter-question – perhaps the more important one: What would I do if I didn’t have this fear? How would I behave? What would I say, plan, dare to do? How different would my life be if this fear wasn’t at the helm?

This question is not an invitation to flee from reality. It is an invitation to recognize how much of what you do not do, do not say, do not dare – is actually fear disguised as reason.

And it gives you something more: it gives you the opportunity to take a look into the future. To feel what it would be like if you no longer had this fear. How you would move. What you would say. What you would dare to do. And this isn’t just an exercise in wishful thinking – it’s neurobiology. The brain cannot reliably distinguish whether it has walked a path before or whether it has only thought and felt it through once. If you really imagine a situation in detail without fear – with all your senses, with the feeling of your body, with your breath, with your inner experience – then it is as if the brain has already had this experience. It creates a new trail. It creates a new possibility. And where before there was only one path – the path of fear, avoidance, retreat – there is suddenly an alternative. Not a forced one. Not a forced one. But one that the brain has experienced as real – and can therefore choose in the future.

That is why it is not about avoiding everything that triggers fear. It is not about retreating into a world of pure security and avoiding everything that is challenging. Life doesn’t allow that anyway – and it wouldn’t be a cure, but just another form of confinement.

It’s about something else. It’s about getting to know them. First: naming the fears in the first place, bringing them out of the semi-darkness of the unconscious into the light of consciousness. Then: find out when they arose. Because fears almost always have a history. They are not personality flaws – they are responses to past experiences, to situations in which security was lacking, in which something hurt or went wrong. The child who was once not enough often still carries this feeling in the adult body. The nervous system remembers – even if the mind has long since ticked it off.

And then: find solutions. Your own, individual ways. This can be psychotherapeutic support, body-oriented methods, naturopathy, acupuncture, NLP, systemic work, meditation – or simply an honest conversation with someone you trust. Sometimes, quietly and patiently looking at yourself over time is enough. There is no one right way. There is only the path that suits you – and the courage to take it.

What it does to your body

A permanently activated sympathetic nervous system leaves traces – in every organ, in every system. Sleep disorders because the brain cannot find its way out of waking mode even at night. Digestive problems because the intestines are not sufficiently supplied with blood under sympathetic dominance. An immune system that is exhausted or derailed – be it in the direction of chronic infections or autoimmunity. High blood pressure, cardiac arrhythmia, chronic pain, silent inflammation in the tissue.

There is hardly a disease in which the autonomic nervous system does not play a role. This is no exaggeration – it is anatomy. This system supplies literally every corner of the body: heart, lungs, liver, kidneys, intestines, skin, glands, immune cells. No organ works independently of which mode the nervous system is currently in. Chronic fatigue, fibromyalgia, irritable bowel syndrome, migraines, psoriasis, neurodermatitis, diabetes, heart disease – despite their different causes, they all have one thing in common: the autonomic nervous system is part of the process. Always.

Conversely, this means that anyone who does not learn to relax – who does not find inner security – will become sicker in the long term. Not because they want to. But because a body in survival mode has no resources left for regeneration. The repair programs do not work. The inflammation regulation fails. And every therapeutic measure, however good it may be, only has a fraction of its potential effect – as long as the nervous system remains permanently on alert.

Relaxation is therefore part of any serious therapy. Not as a nice extra. As a solid foundation.

Safety – the biological entry condition for healing

Your body can only heal when it feels safe enough to let survival pause. The parasympathetic nervous system does not switch on on command. It switches on when the nervous system registers: I am safe.

Stephen Porges describes this process with the term neuroception – the unconscious, constant scanning of the nervous system for signals of safety or danger. Even before your mind has classified anything, your body has already reacted. It reads facial expressions, voices, postures, rooms and smells. It decides in milliseconds: safe or not safe.

And now comes the crucial question – not as rhetoric, but as a genuine invitation to self-reflection: When do you actually feel safe? What do you need to feel safe? What does safety mean to you?

The answer is highly individual. For some, security lies in structure and predictability. For others, it lies in the freedom to be spontaneous. Some feel safe in silence. Others need closeness, warmth and touch. Some find security in the body – through movement, breathing exercises, nature. Others find it in understanding – when something is given a name, when chaos is organized into language.

Security does not come automatically. It often has to be actively built up – internally and externally. Internally: Which beliefs, which images, which memories give you a sense of stability? Externally: Which people, which places, which rituals signal to your nervous system – can I let go here?

That’s why the psyche is always the most important part of any therapy in the end. Without an honest look at yourself – at your feelings, your thoughts, your past, your wishes, your hopes and, above all, your fears – without this getting to know yourself, this gradual understanding of what moves you and what holds you back, you cannot really heal. A nervous system that is a stranger to itself cannot find peace. If you don’t know yourself, you look for security on the outside – and only find it there incompletely.

Safety is not a weakness. It is the prerequisite for everything else.

The vagus nerve – your direct path to safety

At the center of parasympathetic activation is the vagus nerve – the longest cranial nerve in the body, which runs from the brain stem to the abdomen and supplies the heart, lungs, stomach and intestines. It is the main conduit of the parasympathetic nervous system. And it can be trained.

You can actively invite yourself into this state of safety – not through willpower, but through very specific physical signals that tell the nervous system: It’s over. You are safe. You can let go.

Deep, prolonged exhalation is the most direct way. Breathing in for four seconds, breathing out for six to eight seconds – this measurably changes the heart rate variability after just a few minutes. Humming, singing and tinting stimulate the vagus via the laryngeal branches – which is why singing in community has been one of the most effective forms of collective regulation for thousands of years. Genuine social connection – not a substitute for a screen, but real conversation, real eye contact, real touch – is essential nourishment for the nervous system. Cold water on the face activates the diving reflex and lowers the heart rate within seconds. Exercise in nature, without time pressure and without a screen, is one of the oldest forms of human regulation. And Qi Gong and meditation combine breath, body and inner awareness in a way that has a direct effect on vagal tone.

None of these ways replaces the other. The decisive factor is not the intensity, but the regularity – the daily, conscious offer to your nervous system: you can let go.

One last thought

Your autonomic nervous system has accompanied you through everything – through every difficult phase, every loss, every overwhelm, every fear. It has adapted as best it could. What it needs now is not to function on command. It needs an environment – inside and out – in which it feels safe enough to let go.

And that starts with getting to know yourself. Your feelings. Your patterns. Your fears. Not to fight them – but to understand them. Because what we know, we no longer have to fear. And what we no longer fear no longer holds us captive.

Health arises where security arises. And safety arises where you meet yourself.
