How to Recognise Early Stress Signals From Your Nervous System

Finding the secret messages in your unconscious habits

Whenever I’m anxious or under pressure, I catch myself doing this one little thing. At first I don't realise I'm doing it, but others often notice, glancing down and then politely looking away or, if they know me, giving a knowing grin.

That’s when I realise, I’m doing it again.

I’m untying my shoelaces, pulling up my socks and then re-tying those same laces. And to be clear my laces and socks we're fine to begin with. Yes, peculiar I know, but stay with me.

Yep! I have a nervous habit of untying my laces, pulling socks up and then re-tying my shoelaces. Not figuratively pulling up my socks like we’re always told to do, but literally pulling them up, occasionally taking my shoes off to make the adjustment, for good measure.

I’m unsure when or why it started, but for a long time I viewed it as something strange I needed to curb. After all, kicking off your shoes and adjusting  your socks is a bit, well, weird. It felt like one of those unconscious habits that revealed more than I wanted people to see, particularly in professional environments where composure is valued, and taking your shoes off is generally frowned upon.

Let's face facts, it’s not exactly a subtle habit.

Over time though, I’ve started to see this quirk a little differently. The sock-pulling itself isn’t important; it’s a signal that my body feels stress before my mind does

In a strange way, the sock ritual has become a somatic awareness, a small physical cue that my body is generating stress signals before my mind has caught up. The more I’ve paid attention to it, the more I’ve realised this otherwise odd unconscious habit is often connected to my nervous system regulation and my body’s attempt to manage pressure in real time.

Maybe you’re reading this thinking you don’t have an unconscious habit like mine, but the reality is most of us do, even if it's a little more subtle than kicking off your footwear for some sock readjustments. For some it’s coughing unnecessarily during tense moments, rubbing their nose when they’re uncomfortable, tapping a foot under the table or the old favourite, clicking pens repeatedly.

Unconscious habits like mine are often dismissed as quirks, but many are signals that our nervous system has recognised stress before our conscious thinking has fully processed it. 

Research increasingly shows unconscious habits are stress signals, providing an early warning of disequilibrium in our nervous system. Psychologists and neuroscientists studying interoception, the brain’s interpretation of bodily signals, have found that physical responses to stress frequently appear before consciousness catches up. 

The challenge is we have been conditioned to ignore those stress signals presenting as unconscious habits, even the ones a little more discrete than my sock and shoes routine. Professional environments reward composure and emotional control, creating the impression that capable people should remain unaffected by pressure. As a result, people become dangerously good at managing appearances while ignoring early stress signals that come from our unconscious habits.

Whether or not we heed the early warning, the stress being signalled doesn’t disappear, rather surfacing as impatience, defensiveness or the inability to switch off. Organisational psychologists have long found that emotional strain often becomes behaviorally visible long before people openly acknowledge what’s happening internally.

This comes back to subconscious habits and how the nervous system manages stress. When stress isn’t recognised via the early signals of our unconscious habits, the body often keeps signalling in subtle and, eventually, not so subtle ways until the pressure becomes too difficult to ignore.

That's why I’ve begun to embrace the sock and shoe routine that has haunted me for years. When I catch myself pulling my socks up, I now take it as a cue from my nervous system instead of feeling embarrassed. Sometimes this reason is obvious, like I’m avoiding a necessary conversation, carrying pressure I haven’t acknowledged or I’m trying to control an outcome that simply can’t  be controlled. The stress signals manifesting as my need to adjust my socks and footwear creates the opportunity for me to respond earlier and more thoughtfully. It’s part of my nervous system regulation, allowing me to consider and deal with what my consciousness may not yet be aware of.

The more we become attuned to stress signals via unconscious habits, the better chance we have of responding constructively instead of operating purely from reflexive and reactive behaviour.

I still pull my socks up and re-tie my shoes when I’m anxious, and I probably always will. But I no longer see it as something I need to hide or eliminate, it helps me notice when I’m downplaying pressure so I can deal with it before it gets worse. 

For years, I thought the unconscious sock and shoe habit itself was the problem, but really, it was merely a subtle warning.

Is there an unconscious habit you have that could well be a stress signal?
