When difficult experiences affect the body

You wake up feeling tired, even though you have spent eight hours in bed.

Your shoulders are tense. Perhaps you have had headaches, an unsettled stomach or that familiar tightness in your chest.

Life has been demanding lately, but you are managing. You are going to work, looking after your responsibilities and getting through each day. Yet physically, you do not feel quite yourself.

Sometimes the connection is obvious. We feel nervous before an important meeting, or tense after a difficult conversation. Other times, we are so busy getting on with things that we barely notice how much pressure we are under.

So why can emotional stress affect us physically, even when we feel we are coping?

Part of the answer lies in how our bodies respond to pressure, and in how earlier experiences can sometimes shape those responses. Understanding this may help us recognise what is happening, and consider what support might be useful.

Understanding ourselves does not always mean finding a single cause.

One · Mind and body

Our minds and bodies are not separate systems

Think about the last time you felt embarrassed. Perhaps your face became warm, your heart beat faster or you struggled to find the words you wanted.

Or imagine receiving some unexpectedly good news. You might notice a sudden lift of energy or excitement.

These are everyday examples of how our emotions and physical responses interact. The relationship also works in the other direction. Being unwell, exhausted or in pain can affect how we think, feel and respond to situations.

Our brain, nervous system, hormones and other biological processes are continually working together. One of the clearest examples of this is what happens when we are under stress.

Two · The stress response

What happens when we are under stress?

Imagine you are running late for an important appointment. You are caught in traffic, the clock is moving and you know someone is waiting for you.

Your heart starts beating faster. Your shoulders tighten. Your attention narrows to getting there, and perhaps small things that would not normally bother you begin to irritate you.

These changes are part of the body’s normal response to a demanding situation.

The autonomic nervous system helps regulate functions such as heart rate, breathing and digestion. During stress, its sympathetic branch may become more active, and hormones including adrenaline and cortisol help coordinate changes that increase alertness and make energy available.

These responses serve a purpose. They help us react to challenges and potential threats, and usually our bodies settle again as circumstances change.

But when pressures continue, particularly without enough opportunity for recovery, we may begin to notice changes in how we feel and function.

When pressure continues without recovery

A simplified illustration. Stress responses vary considerably between people and are shaped by many factors.

Think about someone managing a demanding job, financial uncertainty and responsibilities at home. There may be no single major event causing distress. Instead, it is the accumulation of smaller pressures, decisions and worries.

They might be managing well in many areas of life while becoming more irritable, more physically tense or finding everyday demands harder than usual. Prolonged stress can affect wellbeing in different ways, although the effects vary considerably from person to person.

Three · Two words, two meanings

Understanding the difference between stress and trauma

We sometimes hear the words stress and trauma used interchangeably. But they do not mean quite the same thing.

Stress is a normal response to situations we experience as demanding, uncertain or difficult to manage. It might arise from work pressures, financial worries, relationship difficulties or having too many responsibilities at once. It can be brief, such as preparing for an interview, or continue over months when circumstances remain challenging. Even pressures we consider ordinary can have a significant effect when they accumulate.

Trauma is different. The term is commonly used to describe experiences that are deeply frightening, threatening or overwhelming, and the lasting psychological effects they may sometimes have. These might include serious accidents, violence, abuse, threats to personal safety or witnessing something deeply distressing. Trauma-related difficulties can also follow repeated or prolonged harmful experiences.

The distinction is not simply whether an experience was stressful. It is about the nature of what happened, and the difficulties that may follow.

Ongoing stressSomeone dealing with continuing work pressures might feel exhausted, irritable and physically tense.

After traumaSomeone who has been in a serious road accident might find certain sounds or journeys bring back intense fear and unwanted memories.

Both experiences can affect wellbeing, but they may involve different psychological processes and call for different kinds of support.

It is also important to recognise that not everyone who experiences a traumatic event develops ongoing difficulties or post-traumatic stress disorder (PTSD). And someone does not need to have experienced trauma for prolonged stress to have a meaningful impact on their health and daily life.

Understanding the difference helps us avoid treating every strong emotional or physical response as evidence of trauma.

Four · Noticing the signs

How might stress show up physically?

Stress does not look or feel the same for everyone. Some people notice physical changes first. Others become aware of differences in their mood, concentration or energy.

Muscle tension: Tight shoulders, jaw tension, neck discomfort or tension-type headaches.
Heart and breathing: A faster heartbeat, changes in breathing or a sense of physical agitation.
Digestion: Changes in appetite, nausea, stomach discomfort or altered bowel habits.
Sleep: Difficulty falling asleep, waking in the night or feeling unrefreshed.
Concentration: Finding it harder to focus, remember information, make decisions or manage competing demands.
Energy: Feeling unusually tired, or finding it difficult to recover after demanding days.

These experiences can have many causes, including medical conditions, medication effects and lifestyle factors. Stress is one possible influence, not an explanation for every symptom.

New, persistent, severe or unexplained symptoms should be assessed by your GP or another appropriate healthcare professional. Sudden or severe chest pain, particularly with breathlessness, fainting or feeling very unwell, needs urgent medical attention: call 999.

Five · Earlier experiences

How earlier experiences can shape our reactions

Sometimes our reactions seem stronger than we would expect. You might feel your stomach tighten before a meeting, even though you know there is nothing particularly worrying about it. Or notice your heart racing when someone speaks sharply, despite knowing you are not in danger.

Consider someone who once worked somewhere criticism was frequent and unpredictable. They may have grown used to feeling anxious whenever their manager wanted to speak with them.

Eventually, they move to a workplace where they are treated with respect. Their new manager is supportive, and there is no reason to expect an unpleasant conversation. Yet an unexpected invitation to a meeting still brings that familiar tightening in their stomach.

One possible explanation involves learning and memory. Through experience, we develop associations between situations and what we expect might happen. A particular tone of voice, setting or interaction can become linked with earlier distress. When something similar happens later, it may bring an emotional or physical response, even though the present circumstances are different.

This does not mean the person is deliberately dwelling on the past. It is one way earlier learning can influence present-day reactions.

These patterns can develop through ordinary experiences as well as more distressing ones. Perhaps someone has repeatedly been criticised for making mistakes, or has learned to avoid disagreement because previous conversations ended badly. Over time, they may begin to anticipate similar outcomes in situations that resemble those experiences.

Recognising a pattern can help us understand it, but it does not automatically tell us why it developed. And it certainly does not mean every uncomfortable response has a traumatic origin.

Six · A closer look at a popular idea

Does the body really store trauma?

You may have come across expressions such as “the body keeps the score”, or heard it suggested that trauma becomes trapped in the body. These phrases are often used to describe how distressing experiences can have lasting effects.

There is a genuine relationship between traumatic memories, emotional responses and physical sensations. Someone who has been in a serious accident, for example, may notice a racing heart or nausea when reminded of what happened. People experiencing PTSD may also notice heightened alertness, unwanted memories, avoidance or strong reactions to reminders of trauma.

However, the idea that traumatic memories are literally stored in muscles, organs or particular areas of the body is not an established scientific explanation. Memory involves complex processes within the brain, while the physical reactions linked with memories involve several interacting biological systems.

Difficult experiences can influence what we remember, what we anticipate and how we respond.

That does not mean trauma is physically trapped somewhere, waiting to be released.

Nor does tension or discomfort automatically suggest unresolved trauma.

The language we use matters, because it shapes how people understand their experiences. An explanation should offer clarity, rather than leave someone worrying that every physical sensation reveals something hidden in their past.

Seven · Pain

When stress and pain overlap

Pain is particularly complex. We often think of it as a straightforward signal from an injured part of the body. But the experience of pain involves the nervous system, and is influenced by biological, psychological and social factors.

Stress can sometimes affect muscle tension or how intensely pain is felt. And living with pain can itself become a significant source of stress.

Imagine someone living with persistent back pain. Everyday activities become more difficult. Tasks that once felt straightforward now take more effort, and they may begin to worry about whether the pain will affect their work or family responsibilities. That worry can add to their distress and make the discomfort harder to cope with. Over time, several difficulties can begin to influence one another.

None of this makes the pain any less real.

Understanding the wider factors involved can help identify additional sources of support, alongside appropriate medical care and pain management. It also reminds us that caring for a person involves more than focusing on one symptom in isolation.

Eight · Sleep

When sleep becomes part of the picture

You might recognise the experience of feeling exhausted all evening, only to become wide awake the moment you get into bed.

Suddenly, you are thinking about tomorrow.

You remember something you forgot to do.

You replay a conversation, or begin worrying about something you cannot resolve right now.

For some people, the difficulty is falling asleep. For others, it is waking repeatedly, or feeling as though they have not rested at all.

The effects can carry into the following day. You may feel more irritable, less patient or find it harder to concentrate. Things that would normally feel manageable can seem much more demanding when you are exhausted, and poor sleep can make existing pressures harder to cope with, creating a cycle that is difficult to interrupt.

For persistent insomnia, cognitive behavioural therapy for insomnia (CBT-I) is an evidence-based treatment and is recommended as the first-line approach for long-term insomnia. Sometimes the most helpful starting point is simply to understand what is interfering with someone’s sleep, and what might help them rest.

Nine · EMDR

Can EMDR help with physical reactions linked to distressing memories?

For some people, the physical responses associated with trauma can be among the most difficult parts of their experience. They may know a situation is safe, yet notice their heart racing, their breathing changing or their muscles tensing. Sometimes these reactions come alongside unwanted memories or images. At other times, the physical response is what they notice first.

Eye Movement Desensitisation and Reprocessing (EMDR) is an evidence-based psychological therapy for PTSD. NICE guidance includes EMDR as a treatment option for adults with PTSD or clinically important PTSD symptoms following non-combat-related trauma, depending on the person’s circumstances.

EMDR involves working with distressing memories through a structured treatment process that includes bilateral stimulation, often guided eye movements. The aim is to reduce the distress associated with traumatic memories and their impact on everyday life. As those memories become less distressing, some people also notice changes in the physical reactions linked with reminders.

EMDR is not simply a matter of revisiting a difficult experience. Assessment, preparation and an individually appropriate pace are important parts of treatment. During processing, attention may be given to the thoughts, emotions and bodily sensations associated with a memory.

However, bodily sensations are not used to diagnose physical illness or to establish that someone has experienced hidden trauma. EMDR is not an established general treatment for unexplained physical symptoms. Whether it is appropriate depends on the difficulties someone is experiencing and a careful clinical assessment.

Ten · Supporting yourself

Looking after yourself during demanding periods

When we feel tense, exhausted or overwhelmed, it is understandable to want something that will make the discomfort disappear. We might look for a breathing exercise, a relaxation technique or a way to quieten racing thoughts.

Some approaches can be useful. But there is no single technique that works for everyone, and not every source of stress can be resolved by changing how we respond internally. Sometimes the pressure comes from circumstances that genuinely need attention: a demanding workload, financial uncertainty, a difficult relationship, caring responsibilities, or a lack of rest and support.

In those situations, relaxation may ease some of the discomfort, but it does not necessarily change what is creating the pressure. It can help to consider both what might help us feel more settled, and what might need to change around us.

Movement that feels manageable

Physical activity can support mood and general health. That does not mean pushing yourself through an intense workout when you are already exhausted. For some people, a walk, gentle stretching or simply changing position after sitting for a long time may feel helpful. What matters is finding something suited to your health and circumstances.

Finding opportunities to recover

Rest does not always mean doing nothing. For some people, it is time outdoors. For others, it is reading, gardening, listening to music or a conversation that does not involve solving a problem. A useful question may be whether there are moments in your day when nothing is being asked of you.

Looking at the pressures themselves

Sometimes we spend a great deal of energy managing our reactions to a situation without asking whether the situation itself could be different. Perhaps a boundary needs to be discussed. Perhaps you are carrying responsibilities that could be shared. Or perhaps there is something you have been putting off because addressing it feels uncomfortable.

Not every circumstance is within our control. But recognising where change or support may be possible can be just as important as learning ways to manage stress.

Noticing patterns without overanalysing

If you are already anxious about your health, constantly checking how you feel may increase worry rather than ease it. So the aim is not to monitor every heartbeat, muscle or change in energy. It is simply to stay open to patterns that might be useful.

Perhaps you notice that headaches are more frequent during particularly demanding weeks, or that your shoulders tense during difficult conversations. Observations like these can offer useful information about how you are responding to everyday pressures, and may help you recognise when something in your routine, responsibilities or circumstances needs attention.

A moment to pause

If it feels helpful, you might gently consider:

Have I noticed any changes in how I feel physically?
Are there particular situations when those changes seem more noticeable?
Have I had enough opportunity to rest and recover?
Has anything in my life been particularly demanding recently?
Are there pressures I could address, or seek support with?
Are there physical symptoms that need medical advice?

These are not questions to answer all at once, or to revisit every day. They are simply a way of looking at the wider picture.

Eleven · Professional support

When might professional support be helpful?

If physical symptoms are worrying you, your GP or another appropriate healthcare professional is a sensible starting point. They can consider possible medical explanations, discuss any investigations that may be needed and help identify suitable treatment.

If stress, anxiety or distressing experiences are affecting your wellbeing, psychological support may also be useful. That might involve exploring current pressures, understanding emotional responses, developing ways of coping or, where appropriate, addressing trauma-related difficulties.

Sometimes people benefit from both medical and psychological care. What matters is finding support that reflects the difficulties someone is experiencing, rather than assuming one approach will address everything.

Twelve · How I work

How I work at Wellness Within UK

In my work as an EMDR therapist and therapeutic coach, I often meet people who are managing a great deal more than might be apparent from the outside. They may be keeping up with work, family life and responsibilities while privately feeling exhausted, anxious or constantly under pressure.

Some have noticed physical tension, or changes in how strongly they react to certain situations. Others are trying to understand why something that happened before still seems to affect them today.

I think it is important to understand what is happening in a person’s life now, what they have experienced before, what they have already tried and what they hope might be different.

Sometimes our work focuses on understanding stress and developing ways of responding to everyday challenges. Sometimes it involves recognising patterns that have become difficult to change. And where trauma-related difficulties are present, EMDR may be an appropriate option following assessment and preparation.

I do not approach everyone with the expectation that we need to explore trauma. The starting point is understanding the individual, their circumstances and what they hope to achieve. For me, the aim is not to find one explanation for everything. It is to work together to identify what support may be genuinely helpful.

In short · What is worth remembering

Emotions and physical responses are closely connected, and the relationship works in both directions.
The stress response is normal and useful; difficulties are more likely when pressure continues without enough recovery.
Stress and trauma are not the same, and not every strong reaction is a sign of trauma.
Trauma is not literally stored in muscles or organs, although distressing memories can bring real physical reactions.
New, persistent or unexplained physical symptoms deserve a medical assessment.
Support can involve medical care, psychological care, practical change or a combination of these.

A final thought

Perhaps you have recognised something of your own experience while reading this. A period when you were managing everything on the outside but feeling exhausted. A physical reaction that seemed stronger than you expected. Or a time when the demands of everyday life left little room to recover.

Sometimes we become so focused on getting through the day that we give little thought to how we are actually feeling. And when we do notice something has changed, we may be unsure what to make of it.

Rather than immediately searching for one explanation, it may be more useful to ask:

What might be influencing how I am feeling, and what would be helpful for me right now?

Sometimes the answer involves practical changes. Sometimes it means seeking professional advice. And sometimes it begins with a conversation about something we have been carrying for longer than we realised.

Often, understanding ourselves means recognising that several things may be contributing, and gently considering what we might do next.
