Your Mind and Body Aren’t Separate: What Happens When Stress Has Nowhere to Go

We often talk about mental health and physical health as though they are two completely separate things.

They aren’t.

Your brain, nervous system and body are constantly communicating with each other. What happens emotionally affects us physically, and what is happening physically can change how we think, feel and respond to the world around us.

This is one of the reasons I think we need to change the conversation around stress.

Because sometimes the question isn’t,“What is wrong with me?”

A better question might be:

“What has my body been trying to cope with for too long?”

We were designed to deal with stress, just not this much of it

The stress response itself isn’t the problem. It is a brilliant survival mechanism.

If you were faced with an immediate threat, your nervous system would very quickly prepare you to deal with it. Your heart rate increases. Blood pressure rises. Glucose becomes readily available for energy. Digestion becomes less of a priority. Muscles tense. Your attention narrows towards the potential danger.

Your body prioritises survival. Once the danger has passed, however, there should be an opportunity to recover.

And this is where modern life can become difficult.

Our threats might not be tigers, but our nervous system is still responding to deadlines, financial worries, difficult relationships, caring responsibilities, illness, bereavement, work pressures, lack of sleep, constant notifications and the never-ending mental list of things we haven’t quite got round to.

One stressful event might be manageable.

But what happens when there is another one an hour later? And another tomorrow?

And you are sleeping badly, rushing meals, relying on coffee to keep going and checking your phone until the moment you fall asleep?

There is very little space for recovery.

When your cup is already full

I often think of our capacity for stress as a cup.

When life is relatively calm and we are sleeping, eating well, moving, resting and feeling supported, there is some room in that cup.

Something stressful happens and we have the capacity to deal with it. But imagine starting every morning with the cup already almost full.

Poor sleep adds a little. Work adds more.

The family WhatsApp goes off. Someone needs something from you.

You skip lunch because you're busy. There is an unexpected bill.

You get stuck in traffic. You remember the thing you forgot to do yesterday.

None of these things individually has to be catastrophic.

But the body experiences the total load. Eventually, something seemingly tiny can make the cup overflow.

You snap at someone you love. You cry over something that normally wouldn’t bother you. Your heart starts racing. You can't concentrate. Your digestion plays up. You wake at 3am with your brain going through everything that needs done. Your shoulders are permanently somewhere around your ears.

And then you wonder why you can't cope with something that looks so insignificant.

Often, it wasn't really about that final thing.

There simply wasn't any capacity left.

Stress doesn't only exist in your thoughts

This is where the connection between mind and body becomes so important.

We experience stress physically. Think about how your body changes when you are anxious, angry, frightened or under pressure.

Your jaw clenches. Your shoulders tighten. Your breathing changes. Your stomach churns. Your heart beats faster. You might feel shaky, restless or unable to sit still.

Or perhaps you go the opposite way and feel completely exhausted, flat and unable to motivate yourself to do anything.

These aren't separate mental and physical experiences. They are different parts of the same stress response.

Experiences from our past can influence that response too. The nervous system learns from what we have experienced. Sometimes the body can react to a situation before our conscious mind has even worked out why it feels threatening.

That doesn't mean every physical symptom is caused by stress, and physical symptoms should always be investigated appropriately.

But it does mean we shouldn't ignore the nervous system when we are trying to understand why someone feels the way they do.

Sometimes we need to look at the environment, not just the individual

One of the things I find interesting about the way we talk about stress and mental health is how quickly the focus can move towards the individual.

Why aren't you coping? Why are you anxious? Why can't you sleep? Why can't you switch off?

Perhaps we also need to ask what we are expecting people to cope with.

For many of us, the boundaries between work and home have almost disappeared. We carry hundreds of people around in our pockets. We can be contacted at any time. We consume distressing news from around the world while making breakfast. We compare our real lives with carefully selected snapshots of everyone else's.

And amongst all of that, we're supposed to eat well, exercise, sleep eight hours, maintain relationships, raise families, look after ageing parents, perform at work and somehow find time for "self-care".

No wonder so many people feel exhausted.

Perhaps some of what we are experiencing isn't evidence that we're failing to cope.

Perhaps our bodies are responding exactly as you might expect them to when the demands consistently outweigh the opportunities to recover.

We need more than "reduce your stress"

Telling someone who is already struggling toreduce their stressisn't particularly helpful.

Most people can't simply remove the job, the financial pressure, the teenager, the caring responsibilities or whatever else is happening in their lives.

We need practical ways to increase our capacity and give the nervous system regular opportunities to experience safety and recovery.

And these don't have to involve completely changing your life. It might be eating breakfast before your first coffee. Putting your phone away earlier at night. Going outside in the morning. Eating lunch away from your desk. Walking after dinner. Singing in the car. Spending time with people who make you feel safe. Taking three slow breaths before you eat. Allowing yourself to rest without feeling that you need to earn it. Getting the nutrients your body needs to support the physiological demands of stress.

Or using hands-on approaches such as Spinal Flow to support the nervous system and help the body move away from constantly being on high alert.

Small moments of recovery matter. Because the aim isn't to create a completely stress-free life.

That's neither realistic nor necessary. The aim is to help your body become better able to move into a stress response when it needs to, and importantly, to move out of it again when the threat has passed.

Maybe the conversation needs to change

There is something powerful about realising that the person sitting next to you who appears to have everything together may also be lying awake at night worrying.

The woman who looks confident might be questioning every decision she makes.

The person who seems incredibly productive might be running almost entirely on adrenaline.

We are very good at hiding the parts of life that feel difficult. And when everyone else appears to be coping, it becomes easy to believe that we are the only ones struggling. I would love to see more honest conversations about this.

Not conversations that dismiss mental health conditions or suggest that every symptom can be solved by regulating the nervous system. There are times when medical and psychological support are absolutely necessary and can be life-changing.

But alongside that, we need to acknowledge something much simpler:

Human beings need recovery.

We need periods where we aren't performing, responding, scrolling, solving problems or anticipating the next thing. Our nervous systems were never designed to spend every waking hour receiving information and responding to demands. Sometimes the most useful place to start isn't asking how we can become better at tolerating an impossible amount of stress.

It's asking what we can do, little by little, to create more room in the cup.

Because when we understand that the mind and body are part of the same system, looking after our nervous system stops being another wellness trend.

It becomes part of looking after our health.
