Subtle Signs You’re More Stressed Than You Think

I was running a workshop recently when I asked the room a question:

How do you know when you’re stressed?

Poor sleep. Irritability. Elevated heart rate. Lack of motivation. Struggling to think clearly. Forgetting things.

And as we were talking through them, I had a slightly uncomfortable realisation.

I could recognise quite a few myself.

That’s the strange thing about stress.

Sometimes you know you’re stressed.

There’s a deadline tomorrow. Something has gone wrong. Your heart is racing and you can feel the pressure immediately.

But sometimes stress doesn’t announce itself like that.

You just start behaving slightly differently.

Your body might notice before you do

Stress isn’t only a feeling.

It’s a physiological response.

That’s why some of the signs can show up physically: a faster heartbeat, muscle tension, headaches, stomach problems or changes in sleep.

But the signs that interest me most are often less obvious.

You might even find yourself reacting much more strongly to something than you normally would.

Individually, none of those things necessarily means you’re stressed.

But when several start appearing together, they’re worth paying attention to.

Sometimes you don’t realise until afterwards

This is the part I’ve found particularly interesting.

You can spend weeks dealing with work, training, relationships, responsibilities, your phone, meetings, deadlines and everything else life throws at you.

And you deal with it.

You keep moving.

Then eventually things calm down.

Your diary gets lighter. The immediate problems are dealt with. You finally have some space.

Great. Can we recover now?

You can still feel exhausted.

Your training might feel flat. Your motivation can still be low. You might find yourself needing far more downtime than you expected.

Removing the stressor doesn’t necessarily mean you instantly feel normal again.

Stress can affect how you think

This one matters.

When we’re stressed, we don’t necessarily make decisions in exactly the same way we would when we’re calm.

Research has linked stress with problems concentrating, forgetfulness and difficulty making decisions.

That means recognising stress isn’t just about feeling better.

It can affect how you communicate, how you work and how you respond to other people.

Sometimes the email that feels like it desperately needs a response tonight probably doesn’t.

Sometimes the argument isn’t worth having.

Sometimes the decision doesn’t need to be made while you’re exhausted and angry.

Sometimes you need to recognise the state you’re in before you act from it.

Stress isn’t automatically bad

It’s also worth saying that stress itself isn’t the enemy.

Some stress is useful.

Training stresses the body. Deadlines can create focus. Competition creates pressure. Challenging yourself requires discomfort.

The problem is when the stress keeps arriving and the recovery doesn’t.

That’s when “I’m just busy at the moment” can quietly become something more serious.

For workplace burnout specifically, the World Health Organization describes it as resulting from chronic workplace stress that hasn’t been successfully managed.

And this isn’t a small workplace issue.

In Great Britain, an estimated 964,000 workers experienced work-related stress, depression or anxiety in 2024/25.

So learning to notice your own warning signs matters.

Learn your signs

Everyone responds differently.

For one person it might be sleep.

For someone else it’s irritability.

Someone else stops wanting to train. Someone becomes forgetful. Someone withdraws socially. Someone notices their heart rate creeping up.

The useful question isn’t just:

“Am I stressed?”

It might be: “What happens to me when I’m stressed?”

Because once you know your patterns, you have a much better chance of catching them early.

And then actually recover

Recognising stress isn’t particularly useful if you respond by continuing exactly as before.

Sometimes something has to give.

Spend time with people without turning it into another networking opportunity.

Use breathing practices if they work for you.

Make space for whatever spirituality, reflection or stillness looks like for you.

A lighter week isn’t going to destroy your progress.

Missing one training session isn’t going to destroy your fitness.

Moving a meeting isn’t going to destroy your career.

Sometimes slowing down is exactly what allows you to keep going.

Pay attention before your body forces you to

We’re very good at normalising stress when we’re ambitious.

It’s part of the job. It’s a busy period. I’ll rest when this project is finished. I’ll slow down next week.

Sometimes that’s genuinely necessary.

But if you keep ignoring the signals, eventually you may not get to choose when you slow down.

That’s why recovery isn’t something to think about only once you’re completely exhausted.

Notice the changes. Learn your warning signs. And recover while they’re still whispers rather than waiting until they have to shout.
