10 Common Symptoms of Burnout: Signs Your Mind and Body Are On the Edge
Burnout is a growing challenge in today’s world, affecting millions across all professions. It’s officially classified by the World Health Organization as an occupational phenomenon, not a medical diagnosis, and it is definitely an issue.
According to The Burnout Report published by Mental Health UK in 2025, workers aged 18–44 are taking 4% more time off for stress-related mental health issues, while only 29% of UK employees report feeling fulfilled at work.
For a deeper look at causes of burnout, risk factors, and evidence-based treatments, see our complete science-backed guide to this work-related condition. Here, we break down the most common physical, emotional, and behavioral signs to watch for.
Fatigue That Doesn’t Go Away
People experiencing burnout often report a wide range of physical issues, including sleep problems, headaches, stomach discomfort, nausea and indigestion, with constant tiredness being one of the most common symptoms.
Burnout fatigue is a deep, stubborn exhaustion that rest rarely fixes, and is often accompanied by “brain fog1” — a sense of mental fatigue, slowed thinking, and difficulty recovering energy unless the underlying stress is resolved. It lingers because chronic stress triggers dysregulation of the autonomic nervous system, disrupting cortisol rhythms.
Research shows this imbalance reduces both mental and physical energy, leading2 to physiological and behavioral changes. Everyday tasks start feeling monumental, even ones you used to do without effort.
Difficulty Concentrating and Lower Productivity
Burnout doesn’t just drain your energy, it can physically change your brain. Neuroscientists remind that it can thin the gray matter in the prefrontal cortex, the part of the brain responsible for self-awareness, perspective, decision-making, and thoughtful reasoning. When this area weakens, it becomes harder to focus, remember information, and learn new things, increasing the risk of mistakes. At the same time, burnout can enlarge the amygdala, the brain’s fear center that drives our “fight-or-flight” response. This combination makes our thinking more reactive and emotional, causing us to perceive the world as more threatening than it really is.
This creates a frustrating loop. Lower productivity heightens stress, which further harms focus: research confirms that people with already existing clinical burnout experience intensified mental fatigue when engaging in cognitive tasks.
Loss of Motivation and Sense of Achievement
Goals that once excited you may now feel overwhelming or irrelevant. Psychologists call this “reduced professional efficacy,” a core burnout dimension linked to self-doubt and harsher self-criticism. Without a sense of accomplishment, work becomes mechanical, feeding disengagement.
This slump in motivation strongly predicts prolonged absenteeism — regularly missing work or being away from your job when you’re scheduled to be there. Studies confirm3 that people with higher burnout levels, especially exhaustion, are more likely to take unplanned days off from work. Burnout also makes them think about quitting: each small rise in burnout score is linked to a 39% higher chance of frequently considering leaving a job.
High absenteeism can not only hurt your wellbeing, productivity and career, but also put extra strain on coworkers, and cost employers money. For example, in the UK, absenteeism costs small businesses (fewer than 250 employees) about £547 per worker each year in lost work hours and replacement expenses, and large organizations with over 1,000 staff face the highest cost — around £702 per person annually.
Cynicism and Negative Attitude Toward Work
Burnout often comes with distress, feeling less capable, and losing motivation, but also with developing an unhelpful or cynical attitude toward work. The phenomena isn’t new: psychologist Herbert Freudenberger introduced the term “burnout” to research in 1974 after observing a troubling pattern among volunteers at a free clinic in New York City. Once highly motivated and idealistic, these mental health workers began to feel emotionally drained, cynical, and resentful toward the very patients they wanted to help.
You might catch yourself rolling your eyes at meetings, feeling detached from projects, or distrusting leadership. While cynicism can feel like self-protection from disappointment, research links it to lower job satisfaction, strained relationships, and higher job turnover. Left unchecked, it corrodes your life and workplace culture.
Emotional Exhaustion and Feeling Numb
In 1993, psychologist Christina Maslach described burnout as having three core dimensions: emotional exhaustion (feeling drained and unable to cope), depersonalization (developing a detached, negative attitude toward clients or customers, and losing personal ideals), and reduced personal accomplishment (feeling ineffective, unproductive, and less committed to one’s work or profession). This framework remains one of the most widely used models for understanding burnout today.
Emotional exhaustion shows up as a sense of running on empty, feeling too depleted to connect or care. Detachment often follows, creating an emotional buffer that can protect short-term energy but at the cost of warmth and connection. Over time, this numbness can erode personal and professional relationships.
Research consistently shows that social identification and social support help protect against burnout, highlighting the importance of early intervention and building supportive networks for effective recovery.
Irritability, Anger, and Mood Swings
Key findings from The Burnout Report 2025 reveal that stress levels have increased compared to 2024, with 9 in 10 UK workers experiencing high or extreme levels of pressure or stress.
Where does it leave us? Chronic stress disrupts4 serotonin and dopamine balance, making it harder to regulate mood. Small inconveniences feel bigger, and patience wears thin. No surprise you might be snapping at minor annoyances or feeling on edge without clear reason. Recognizing these mood shifts early opens the door for helping strategies: physical activity, breathing exercises, and deliberate downtime, that can rebalance emotional stability.
Trouble Sleeping or Persistent Insomnia
Burnout frequently disrupts sleep patterns, even in people who never struggled before. The stress response system, particularly the HPA axis, becomes dysregulated, making it harder to fall asleep, stay asleep, or wake up feeling refreshed.
One of the earlier studies found5 that people experiencing burnout were almost twice as likely to develop insomnia within 18 months. Similarly, those with insomnia were more likely to develop burnout during the same period. In other words, burnout and insomnia feed into each other, with each condition increasing the risk of the other over time.
Poor sleep in turn worsens6 concentration, mood, and resilience, creating a vicious cycle. Prioritizing sleep hygiene like consistent bedtimes, no screens before bed, and calming routines, can help break the loop, but deeper burnout recovery often requires broader stress management.
Frequent Headaches, Muscle Pain, and Stomach Problems
Burnout often shows up in the body before the mind fully catches on. Tension headaches, neck and back pain, and digestive issues are common physical expressions of chronic stress. Other frequent symptoms include a pounding or racing heart, joint and limb pain, chest pain, and shortness of breath. Menstrual problems and sexual pain can also occur, along with fainting and general feelings of fatigue or low energy.
Nearly all patients with burnout report7 at least one physical symptom and many have six or more. Chest pain and sexual problems were more common in men, while older patients reported more joint and limb pain. Overall, these physical symptoms are closely linked to stress and affect men and women, young and old, equally.
Withdrawing from Friends, Family, and Colleagues
Social withdrawal is a classic burnout sign, and a real red flag. When exhaustion sets in, people often cancel plans, avoid calls, or disengage at work. Withdrawing from social interactions may go hand in hand with losing empathy, which psychiatrists understand as a general “inability to feel” or emotional numbness. It also cuts off one of the strongest buffers against burnout: social support8. Isolation accelerates emotional exhaustion and slows recovery. Staying connected, even in small ways, can help interrupt the downward spiral.
Depression Symptoms
There’s been ongoing debate about whether burnout and depression are the same or different conditions since burnout often shares symptoms like loss of interest and difficulty concentrating. However, while they may overlap, important differences in their symptoms and causes set them apart.
People with burnout tend to have less social withdrawal but more empathy loss than those with depression, and the second more often experience low mood, loss of interest, feelings of low self-worth, passive suicidal thoughts, and oversleeping. Psychiatrists find burnout to be more similar to reactive depression — the one primarily triggered by external stressors and life events, rather than biological factors.
To explore this problem deeper, researchers conducted9 a systematic review and meta-analysis of studies published over the course of 10 years examining the relationship between burnout, depression, and anxiety. While they found a clear connection between burnout and both depression and anxiety, the findings suggest that burnout is a distinct condition, not a form of depression or anxiety, and should be addressed differently. Depression is typically treated with therapy and medication, whereas burnout is often managed by improving work environments and making lifestyle changes.
