Stress gets talked about as though it’s primarily a mental or emotional experience — something you feel. But stress is fundamentally a physiological event, and its physical effects on the body are extensive, well-documented, and significant. Understanding what stress actually does in the body is one of the most useful things you can do for your health.
The Stress Response
When the brain perceives a threat — whether that’s a physical danger, a difficult conversation, a work deadline, or a worrying thought — it triggers the hypothalamic-pituitary-adrenal (HPA) axis. The adrenal glands release cortisol and adrenaline. The body mobilises for action: heart rate increases, blood pressure rises, blood is redirected to the muscles and away from the digestive organs, the immune system’s anti-inflammatory response is suppressed, and non-essential functions are reduced.
This response is brilliant in an acute emergency. The problem is that for most people in modern life, it runs continuously — triggered by psychological and social stressors dozens of times a day, never fully completing its cycle, never returning the body to proper rest.
What Chronic Stress Does
Chronically elevated cortisol disrupts virtually every system in the body. Digestion suffers — which is why stress reliably causes or worsens IBS, bloating, constipation, and acid reflux. Immunity is suppressed — which is why stressed people get more colds, take longer to heal, and are more prone to inflammatory conditions. The hormonal system is disrupted — cortisol suppresses progesterone production, interferes with thyroid function, and destabilises the entire endocrine cascade. Sleep is affected because cortisol should be low at night, and chronically elevated levels prevent the deep, restorative sleep the body needs.
Cardiovascular health, blood sugar regulation, bone density, skin, and reproductive health are all affected by chronic stress. The brain itself changes — the amygdala (threat detection) becomes hyperactivated, while the prefrontal cortex (rational thinking, perspective) becomes less effective. This is why chronic stress makes it harder to think clearly, maintain perspective, and feel emotionally stable.
The Body’s Storage of Stress
Unresolved stress doesn’t disappear — it accumulates in the body’s tissues. Muscle tension patterns, altered breathing habits, chronic postural holding, and the energetic imprints that approaches like Emotion Code work with are all physical residues of stress that wasn’t fully discharged. This is why people carry stress in their shoulders, their jaw, their gut — and why those physical patterns persist even when the original stressor is gone.
How Holistic Therapy Addresses Stress Physically
This is exactly the territory that all of the therapies I offer address. Reflexology produces measurable reductions in cortisol and activates the parasympathetic response. Reiki induces deep nervous system relaxation. Craniosacral therapy releases the deep holding patterns in the central nervous system. KORE Therapy addresses the structural, energetic, and emotional dimensions simultaneously.
I’m based in Wilby, near Wellingborough, and I see clients from across Northamptonshire. More about how I work with stress and nervous system regulation is on the trauma and emotional release page.
Frequently Asked Questions
How do I know if stress is affecting my physical health? Common signs include chronic muscle tension (especially shoulders, neck, jaw), digestive problems, poor sleep, frequent illness, fatigue, hormonal disruption, and a feeling of never quite recovering between demands.
Can you reverse the physical effects of long-term stress? Yes — the body has remarkable capacity for recovery when the stress response is finally regulated. Holistic therapy is one of the most effective ways to initiate and support that recovery process.
Where should I start? I’d suggest starting with whichever therapy resonates most, and discussing your specific physical symptoms in the first session so we can target the approach to what your body most needs. Get in touch to discuss.
