Burnt out? The three signs and one thing to do about it!

We live in a culture that glorifies busy. We wear exhaustion like a badge of honour, push through when our bodies beg us to stop, and convince ourselves that rest is something we'll earn later. But there's a point where "tired" becomes something more serious — and that point is burnout.

As a naturopathic doctor, I see burn out manifest for many folks in their health journey. Although it has been classically considered an “occupational diagnosis”, it doesn't just affect high-powered executives or overworked parents. It shows up in students, caregivers, healthcare workers, entrepreneurs, and anyone who has been giving more than they've been able to restore. The tricky thing about burnout is that it creeps in slowly, and by the time most people recognize it, they've been running on fumes for months.

So let's talk about what burnout actually looks like — and one surprisingly powerful tool to begin the recovery process.

The Signs of Burnout

Burnout isn't just being tired. It's a state of chronic depletion — physical, emotional, and cognitive — that doesn't resolve with a good night's sleep or a weekend off.

The three key signs to watch for:

Persistent, bone-deep exhaustion. This goes beyond normal fatigue. You wake up already tired. Rest doesn't restore you. You feel depleted before the day has even begun, and no amount of sleep seems to touch it.

Emotional detachment and cynicism. Things that used to matter to you — your work, your relationships, causes you care about — start to feel meaningless. You go through the motions. You feel numb, disconnected, or inexplicably resentful.

Reduced sense of accomplishment. Even when you complete tasks, nothing feels satisfying. You second-guess yourself constantly, feel ineffective, and struggle to see the value in what you're doing. The inner critic gets louder.
Here’s a fun FYI for ya on this one: This symptom most commonly shows up in cis-females. Their cis-male counterparts who may be equally burnt out do not actually feel a reduced sense of accomplishment.

Other symptoms that can come along with burn out:

Cognitive fog. Concentration becomes difficult. You lose your train of thought mid-sentence, forget things you normally wouldn't, and feel like your brain is running through mud. Decision-making, even for small things, feels overwhelming.

Physical symptoms with no clear cause. Burnout lives in the body. Headaches, digestive issues, frequent illness, muscle tension, heart palpitations, disrupted sleep, and changes in appetite are all common. The nervous system has been in overdrive for so long that the physical toll becomes undeniable.

Social withdrawal. Interactions that would normally energize you start to feel like demands you can't meet. You cancel plans, become irritable with loved ones, and crave isolation — not as restoration, but as collapse.

Loss of joy. Activities, hobbies, or people that once brought you pleasure stop feeling good. This flattening of affect is one of the most telling signs that the system is genuinely overwhelmed.

If you're nodding along to several of these, I want you to know: this is not a character flaw. Burnout is a physiological and psychological response to sustained, unrelenting stress. And recovery is possible.

And if you’re looking at the list and thinking “hmmm that also sounds like some other diagnoses”, you are correct! As I say, diagnosing burn out correctly requires a full assessment to ensure that we have the right condition and therefore the right treatment.

There are also specific assessments created to screen for burn out. Speak to your healthcare provider to get more information and proceed with an assessment!

One Tool to Begin the Recovery: Gratitude Journaling

I know what some of you are thinking. Gratitude journaling? <Insert eye roll> BUT hear me out because the science behind this practice is genuinely compelling, and it works precisely because of what burnout does to the brain.

Why the Brain Needs This

Chronic stress and burnout fundamentally alter brain function. Prolonged elevated cortisol — the body's primary stress hormone — shrinks the hippocampus (involved in memory and learning) and hyperactivates the amygdala, the brain's threat-detection centre. The result is a nervous system locked in survival mode: scanning for danger, amplifying negative experiences, and filtering out the good.

This is called the negativity bias, and burnout throws it into overdrive. Your brain becomes a machine for finding problems. Every interaction feels like a threat. Every small difficulty feels insurmountable. This isn't pessimism — it's neurobiology.

Here's where gratitude journaling intervenes.

Research in neuroscience and positive psychology shows that deliberately focusing on gratitude activates the brain's reward circuitry — specifically the medial prefrontal cortex and the limbic system. This stimulates the release of dopamine and serotonin, two neurotransmitters central to mood regulation, motivation, and a sense of wellbeing — all of which are depleted in burnout.

Crucially, gratitude also activates the parasympathetic nervous system — the "rest and digest" branch that is the physiological antidote to the fight-or-flight state burnout locks you into. Regular gratitude practice has been shown to lower cortisol levels, reduce inflammatory markers, and improve heart rate variability — a key indicator of nervous system resilience.

Perhaps most importantly, gratitude journaling begins to rewire neural pathways through a process called neuroplasticity. The brain is experience-dependent: The more you deliberately direct attention toward positive experiences, the stronger those neural circuits become. You are, quite literally, training your brain to notice what is working — counteracting the negativity bias that burnout has entrenched.

If you want to recover from burn out but you are uninterested in training your brain, it’s the equivalent of wanting biceps but refusing to do a bicep curl.

A landmark study by Emmons and McCullough (2003) found that participants who wrote weekly about things they were grateful for reported higher levels of wellbeing, more optimism, fewer physical complaints, and more hours of sleep than those who wrote about hassles or neutral events. More recent neuroimaging studies have shown that even brief gratitude exercises produce measurable changes in brain activity — particularly in regions associated with moral cognition, reward, and interpersonal bonding.

How to Actually Do It

The goal is not to perform positivity or pretend everything is fine. Burnout recovery requires honesty. This practice works best when it's simple, consistent, and genuine.

Start small. Three to five minutes before bed is enough. You don't need a special journal — a notebook, a notes app, whatever creates the least friction.

Write three specific things you're grateful for. Specificity matters more than quantity. "I'm grateful for coffee" lands differently in the brain than "I'm grateful for the ten minutes I sat quietly with my coffee this morning before the day started." Specificity requires you to actually relive the experience, which deepens the neurological effect.

Include at least one thing related to a person. Social connection is a core human need that burnout systematically erodes. Acknowledging gratitude for someone — even briefly — begins to rebuild that sense of connection.

Don't force it on hard days. On the days when you can barely find anything, write smaller. "My bed is comfortable." "I had enough to eat." "The meeting ended on time." That's enough. The practice is about direction, not performance.

A Note on Recovery

Gratitude journaling is a starting point — a way to begin shifting your nervous system out of survival mode. It is not a substitute for sleep, nourishment, boundaries, or professional support when needed. Burnout is a serious condition, and full recovery often requires looking honestly at the structural and lifestyle factors that contributed to it in the first place.
