How Stress Becomes Suffering: A Nervous System Perspective
Updated: Sep 12
Many stressful situations in life cannot be immediately changed. A difficult workplace may take time to leave. Financial or family responsibilities may limit our options. Broader social or political uncertainty can create instability that no individual person can control.
Stress is a natural response to these situations.
The difficulty is that stress does not always end when the immediate moment has passed. The body may stay tense. The mind keeps going over what happened. Sleep may be affected. Small demands begin to feel harder to manage. Over time, the original stressor and our ongoing response to it can begin to create additional strain.
Understanding this can help us think differently about what it means to cope with difficult periods of life.
Stress Is a Natural Response
When something feels challenging, uncertain, or threatening, the brain and body prepare us to respond. Heart rate may increase. Breathing changes. Muscles prepare for action. Attention shifts toward what needs to be dealt with. Stress hormones such as adrenaline and cortisol also help mobilize energy.
In the short term, these responses are useful. They help us focus and take action.
The problem is not that we have a stress response. Difficulty develops when stress continues for long periods of time, when there is little opportunity for recovery, or when one demand is followed quickly by another.
When Stress Continues
Some stressors resolve quickly. Others do not. Work problems, caregiving responsibilities, financial pressure, relationship conflict, health concerns, or ongoing uncertainty may continue for months or even years.
Under these conditions, people may notice that they are:
constantly tense
mentally overloaded
unable to fully relax
more easily irritated
exhausted but still unable to slow down
overwhelmed by demands they could normally manage
This is not simply a failure to cope. The body and mind are spending more time responding to stress and less time recovering from it. Over time, that has a cost.
How We Protect Ourselves Under Stress
People respond to prolonged stress in different ways. These patterns are influenced by temperament, past experience, the current situation, and what responses are actually available.
Bracing and Chronic Tension
Some people notice that they physically brace when they are under stress.
The jaw tightens.
The shoulders lift.
The abdomen stays tense.
Breathing may become shallower.
These changes can happen without much conscious awareness.
If they continue throughout the day, physical tension itself can become uncomfortable and tiring.
Sometimes simply noticing the bracing is useful. Not because the body needs to be forced to relax, but because it creates an opportunity to ask: Do I still need to be holding myself this way right now?
Withdrawal and Shutdown
Other people respond to overwhelming stress by pulling back. They may feel numb, exhausted, disconnected, or unable to think clearly. Concentration becomes harder. Tasks that normally seem manageable may feel like too much. People sometimes describe this as shutting down or mentally checking out.
There is no single physiological explanation for all of these experiences. But they can occur when someone has been dealing with more stress than they currently have the capacity to manage.
Appeasing and Social Stress
Another pattern is appeasing or accommodating other people in order to reduce conflict.
This may become especially noticeable in situations where speaking up feels risky — a difficult workplace, a strained family relationship, or an environment with a strong power difference.
A person may agree quickly, soften what they really want to say, monitor another person's mood, or avoid bringing up something that could create conflict.
The body may change too.
Someone may notice:
taking up less space
speaking more quietly or cautiously
tension in the throat
difficulty finding words
becoming very focused on another person's reaction
People sometimes describe this as “losing their voice” under stress.
Appeasing can make sense in situations where keeping the peace has felt safer than confrontation. But when it becomes automatic, it can also make it harder to notice and express one's own needs.
The Brain and Body Influence Each Other
Stress is not only something that happens in our thoughts.
The brain is constantly receiving information from inside the body — including signals related to breathing, heart rate, muscle activity, and other internal sensations.
At the same time, thoughts, attention, memories, and the environment can influence what happens in the body.
The relationship goes both ways.
For example, someone who is already tense may become more aware of a racing heart or tight chest. Those sensations may then increase worry, which can further increase physical activation.
This does not mean that posture or muscle tension tells the brain that danger is present.
It means that bodily sensations are one part of the information the brain uses when making sense of what is happening.
Under prolonged stress, these feedback loops can sometimes add to distress.
The Cost of Chronic Stress
When stress continues without enough recovery, people may begin to notice changes in both physical and mental functioning.
These can include:
persistent muscle tension
fatigue
changes in sleep
irritability
difficulty concentrating
feeling overwhelmed more easily
a persistent sense of pressure or urgency
Chronic stress affects more than one part of the nervous system. It involves interactions among the brain, autonomic nervous system, hormonal stress systems, immune system, sleep, behavior, and the person's environment.
I discuss this in more detail in my article on trauma, chronic stress, and the body.
Stress does not affect everyone in the same way. But when demands repeatedly exceed opportunities for recovery, everyday life can begin to require much more effort.
Creating More Capacity
Regulation does not mean being calm all the time. It also does not mean eliminating stress. Sometimes the situation really is stressful. The goal is to have more capacity to move between activation and recovery rather than remaining tense, overwhelmed, or disconnected for long periods of time.
Small changes can matter. A person might notice tension earlier. They may realize that they are holding their breath during a difficult conversation. They may pause before automatically saying yes. They may recognize when they need movement, rest, support, or time away from a demanding situation.
Somatic practice and psychotherapy can be useful here because it brings attention to what is happening in the body while stress is occurring, rather than only thinking about the situation afterward. The goal is not to make every uncomfortable sensation disappear. It is to have more options in how we respond.
Stress Without Added Suffering
Some difficult circumstances cannot be changed immediately. Recognizing this matters.
Somatic practice and psychotherapy should not be used to suggest that people can regulate their way out of unsafe working conditions, financial pressure, discrimination, illness, relationship problems, or other real sources of stress. Sometimes the environment needs to change.
At the same time, noticing how stress is affecting the body can help reduce some of the additional strain that develops around an already difficult situation. The challenge may still be there. But there may be less bracing, less automatic accommodation, or more ability to pause and decide what is needed next.
This is not about becoming unaffected by stress. It is about having more capacity to respond to what is actually happening without carrying every difficult moment forward into the next one.
