Why we hold stress in the body: A guide to somatic therapy and nervous system regulation

Have you ever noticed your shoulders creeping up towards your ears while reading a stressful email? Or perhaps you clench your jaw during difficult conversations, or feel a sudden, unexplainable knot in your stomach when your phone rings. If these physical reactions sound familiar, you are already experiencing how we hold stress in the body.

For a long time, we have been taught to think of mental health as something that happens entirely in our heads. We try to think our way out of anxiety, logic our way out of depression, and talk our way through trauma. But our bodies and minds are not separate entities. They are deeply connected, and when we experience chronic stress or difficult events, our physical form often absorbs the impact.

This is where somatic therapy and nervous system regulation come into play. Somatic therapy is an approach that acknowledges the physical reality of our emotional experiences. It offers a way to release trapped tension, calm an overwhelmed nervous system, and help you feel safe in your own skin again.

In this guide, we will explore exactly why your body holds onto stress, how your nervous system reacts to the modern world, and how somatic therapy can help you find a deeper sense of calm.

What does it mean to hold stress in the body?

When we talk about holding stress in the body, we are not speaking in metaphors. Emotions are physiological events. When you feel angry, scared, or overwhelmed, your brain sends a cascade of chemicals and electrical signals throughout your entire body.

In an ideal scenario, a stressful event happens, your body reacts to help you survive it, and then your body returns to a state of rest. Think of a deer being chased by a predator. The deer's heart races, its muscles flood with energy, and it runs. Once the deer escapes and is safe, it will often literally shake its body to discharge that excess survival energy, and then go back to calmly grazing.

Humans, however, rarely shake off our stress. We sit at our desks, grip our steering wheels, and swallow our frustration. Because we do not physically process the biological stress response, that survival energy gets trapped. Our muscles stay slightly contracted. Our breathing remains shallow. Our body acts as if the threat is still present, even if the stressful event happened years ago.

Over time, this trapped energy manifests as physical symptoms. You might visit a GP for mysterious back pain, chronic headaches, or digestive issues, only to be told that your test results are clear and it is "just stress". If you are curious about how your emotions might be manifesting physically, you can take our PHQ-15 somatic symptoms test to better understand your current physical symptoms.

The science behind stress and nervous system regulation

To understand somatic therapy, it helps to understand a little bit of biology, specifically the autonomic nervous system. This system runs automatically in the background, controlling things like your heart rate, digestion, and breathing.

Your autonomic nervous system has two main branches. The sympathetic nervous system is your internal gas pedal. It is responsible for the fight-or-flight response. When it is activated, your heart rate increases, your pupils dilate, and blood rushes to your muscles so you can deal with a threat.

The parasympathetic nervous system is your internal brake. It is responsible for resting, digesting, and restoring. When this branch is active, your heart rate slows down, your breathing deepens, and your body focuses on healing and repair.

A healthy nervous system moves fluidly between these two states. This is known as nervous system regulation. You encounter a challenge, your sympathetic nervous system kicks in to help you handle it, and then your parasympathetic nervous system helps you calm down.

However, chronic stress or trauma can break this natural rhythm. Your nervous system can become stuck. You might get stuck on the gas pedal, leading to chronic anxiety, panic, and a constant feeling of being on edge. Alternatively, you might get stuck on the brakes, leading to a freeze response, depression, numbness, and exhaustion. If you want to check your current stress levels, our DASS-21 stress test can provide some helpful insights.

Therapists often talk about the "window of tolerance". This is the optimal zone of arousal where you can manage everyday stress without getting completely thrown off balance. When your nervous system is dysregulated, your window of tolerance shrinks, making even minor inconveniences feel like massive threats.

Signs your nervous system is dysregulated

Because the nervous system connects to every organ in your body, a dysregulated system can cause a wide variety of symptoms. Sometimes these signs are subtle, while other times they are impossible to ignore.

Physical signs that you might be holding stress in your body include:

• Chronic muscle tension, especially in the jaw, neck, shoulders, and hips.
• Frequent headaches or migraines that seem to flare up during busy periods.
• Digestive issues, such as bloating, nausea, or irritable bowel syndrome (IBS).
• A racing heart or a feeling of fluttering in your chest when there is no immediate danger.
• Shallow, rapid breathing, or frequently catching yourself holding your breath.
• Chronic fatigue that does not improve with a good night of sleep.

Emotional and behavioural signs of dysregulation can include:

• Feeling constantly on edge, jumpy, or easily startled by loud noises.
• A persistent sense of dread or waiting for the other shoe to drop.
• Difficulty concentrating, brain fog, or feeling detached from reality.
• Snapping at loved ones over minor issues due to a low tolerance for frustration.
• Feeling emotionally numb, disconnected, or completely shut down.

It is important to distinguish between temporary stress and chronic dysregulation. If you are unsure where you stand, reading our article on Burnout vs stress: How to spot the signs and when to take a step back can help clarify what you are experiencing.

What is somatic therapy?

Somatic therapy, also known as somatic experiencing or body-based therapy, is a therapeutic approach that places the body at the centre of the healing process. The word "somatic" comes from the Greek word "soma", which simply means the living body.

While traditional therapies focus primarily on the mind, somatic therapy operates on the principle that trauma and chronic stress are physiological experiences. Therefore, they must be addressed on a physical level. Somatic therapy aims to help you safely release pent-up survival energy, process difficult emotions, and restore a sense of safety within your physical self.

A somatic therapist will guide you to pay close attention to your physical sensations. Instead of just asking, "How did that make you feel emotionally?", they might ask, "Where do you feel that anger in your body right now?" or "What happens to your breath when you talk about that memory?"

The goal is not to relive trauma or dive deeply into painful narratives. In fact, somatic therapy is often very gentle. The focus is on helping your nervous system complete the biological stress responses that were interrupted in the past, allowing your body to finally understand that the danger has passed.

How somatic therapy differs from traditional talk therapy

To understand the value of somatic therapy, it helps to look at how the brain processes information. Traditional talk therapies, such as cognitive behavioural therapy (CBT), use what is called a "top-down" approach. They start with the conscious mind, helping you change your thoughts and beliefs, which in turn influences your emotions and bodily responses.

Top-down approaches are highly effective for many people and are the standard treatment offered by NHS Talking Therapies. However, when it comes to deep-rooted trauma or chronic nervous system dysregulation, top-down therapy sometimes hits a wall. You might logically know that you are safe, but your body still feels terrified. You cannot simply think your way out of a racing heart.

Somatic therapy uses a "bottom-up" approach. It starts with the body and the nervous system, addressing the physical sensations of stress first. By calming the body, it sends a message up to the brain that you are safe, which then allows your thoughts and emotions to settle.

Neither approach is inherently better than the other. In fact, many therapists integrate both. If you are curious about how different methods compare, our guide on CBT and beyond: Understanding different types of therapy explores this in more detail. But for those who feel they have talked about their problems for years without feeling any physical relief, somatic therapy often provides the missing piece of the puzzle.

Common techniques used in somatic therapy

If you have never experienced somatic therapy before, you might wonder what actually happens in a session. It is important to note that you will still talk with your therapist, but the conversation will frequently anchor back to your physical experience. Here are some common techniques your therapist might use.

Body scanning: Your therapist will ask you to direct your attention to different parts of your body, noticing any areas of tension, warmth, cold, numbness, or relaxation. This builds your interoception, which is your ability to perceive sensations inside your body.

Resourcing: Before exploring any difficult emotions, a somatic therapist will help you build "resources". These are internal or external things that make you feel safe and grounded. It could be the feeling of your feet on the floor, a comforting memory, or focusing on a part of your body that feels neutral and calm.

Titration: Trauma can be overwhelming to process all at once. Titration involves breaking down difficult experiences into very small, manageable pieces. You only process a tiny drop of distress at a time, ensuring your nervous system does not become flooded or re-traumatised.

Pendulation: This technique involves gently guiding your attention back and forth between a state of stress and a state of calm. You might focus on a tight knot in your chest for a moment, and then shift your focus to the grounded feeling of your feet on the floor. This teaches your nervous system that it can experience stress and successfully return to a state of safety.

Movement and discharging: Sometimes, the body needs to physically move to release trapped energy. A therapist might encourage you to allow a natural physical response to happen, such as shaking, trembling, pushing your hands against a wall, or taking a deep, vocal sigh.

Who can benefit from somatic therapy?

Somatic therapy can be beneficial for almost anyone, as we all experience stress and hold tension in our bodies. However, it is particularly effective for certain challenges where the body is deeply impacted.

It is widely recognised as a powerful approach for trauma. If you have experienced a single traumatic event or complex, ongoing trauma, your nervous system may be stuck in survival mode. Somatic approaches are often a core component of therapy for trauma and PTSD, as they help process the trauma safely without requiring you to retell the painful story repeatedly.

People struggling with chronic anxiety also find great relief in somatic work. Anxiety is highly physical, often bringing a racing heart, shallow breathing, and muscle tension. Somatic therapy for anxiety teaches you how to interrupt the physical panic cycle and signal safety to your brain.

Additionally, those dealing with burnout, chronic fatigue, or unexplained physical pain can benefit immensely. When you are burnt out, your nervous system is depleted. Somatic therapy helps you gently rebuild your energy reserves and learn how to rest properly.

Simple ways to start regulating your nervous system at home

While working with a trained somatic therapist is the safest way to process deep trauma, there are many gentle nervous system regulation techniques you can practice on your own. These simple tools can help you expand your window of tolerance in everyday life.

The physiological sigh: This is a breathing technique scientifically shown to rapidly lower stress. Take two quick inhales through your nose, followed by one long, slow exhale through your mouth. Repeat this three to five times. The double inhale fully inflates the lungs, and the long exhale engages the parasympathetic nervous system.

Orienting to your environment: When you feel overwhelmed, your brain often acts as if you are in immediate danger. Look around the room and slowly name five objects you can see, focusing on their colours and textures. This simple act tells your brain that you are present in a safe environment right now.

Therapeutic shaking: Remember the deer shaking off its stress? You can do this too. Stand up and gently start shaking your hands, then your arms, then your legs, and finally your whole body. Do this for one or two minutes. It is a fantastic way to discharge nervous energy after a stressful meeting or a difficult commute.

Temperature shifts: Cold water stimulates the vagus nerve, which is a major part of your parasympathetic nervous system. If you are feeling panicked or highly anxious, try splashing cold water on your face, holding an ice cube, or placing a cold flannel on the back of your neck.

Mindful touch: Place one hand on your heart and the other on your belly. Notice the warmth of your hands. Feel the gentle rise and fall of your breath beneath your palms. This self-soothing touch releases oxytocin, a hormone that promotes feelings of safety and connection.

Finding the right somatic therapist in the UK

If you are ready to explore somatic therapy, finding the right professional is an important first step. In the UK, somatic therapy is most commonly accessed through private practice, as NHS Talking Therapies primarily focus on cognitive and behavioural approaches.

When searching for a therapist, it is vital to ensure they are properly qualified and registered with a professional body, such as the British Association for Counselling and Psychotherapy (BACP), the UK Council for Psychotherapy (UKCP), or the Health and Care Professions Council (HCPC). You should look for practitioners who specifically mention somatic experiencing, sensorimotor psychotherapy, or body-oriented psychotherapy in their profiles.

The relationship you have with your therapist is the most important factor in your healing. You need to feel physically and emotionally safe with them. Do not be afraid to ask potential therapists about their specific training in somatic modalities and how they usually structure their sessions.

Taking the next step towards healing

Holding stress in the body is a natural, biological response to a challenging world. Your body has been working incredibly hard to protect you, absorbing the impact of difficult experiences so you could keep going. But you do not have to carry that tension forever.

Somatic therapy and nervous system regulation offer a compassionate, gentle path back to yourself. By learning to listen to your body's signals and working with your biology rather than against it, you can release trapped stress, expand your capacity for joy, and finally feel at home in your own skin.

Remember that healing is not about never feeling stressed again. It is about building a resilient nervous system that knows how to return to a place of calm.
