Prolonged stress impairs the prefrontal cortex

How burnout alters your brain

Stress is a normal part of everyday life, and it’s not necessarily all bad. But chronic stress—the kind that leads to burnout—can change the size and functioning of parts of your brain. It can alter the ability to make new brain cells and memories and even potentially modify your DNA.

Stress and the brain

While an acute stress response is a normal bodily function, the effects of chronic stress can be extremely damaging to the human body. This is particularly true with regard to the brain. This article explores the effects of stress on the human brain, including how chronic stress may lead to psychological conditions such as depression and memory loss.

Clinical burnout: prolonged exhaustion, mental distance, and persistent negative feelings

Burnout isn’t just stress—it’s a pervasive feeling of exhaustion that can start in the workplace and seep into everyday life. It causes feelings of dread and cynicism about work tasks. On top of emotional distress, there can be physical symptoms and a tendency towards addictive behavior.

What happens to your brain when you burn out?

You've probably heard of burnout, also known as the feeling of exhaustion that happens after a long period of being overwhelmed or stressed. It's often associated with work and careers, but other parts of life, like parenting, can cause burnout, too. Scientists are figuring out what happens, biochemically speaking, in the brain when burnout hits—and spoiler alert, it includes a neurotransmitter called glutamate. Watch this video to learn more.

Chronic stress affects nearly all parts of the body

Stress is our body’s internal mechanism to deal with changes in our internal balance. As such, the stress response affects nearly every organ system through a cascade of both fast and slow hormonal changes. While short-term stress can be adaptive, long-term stress may cause serious health issues.

Grief rewires the human brain

The human brain handles stress and emotional traumas similarly. In response to the emotional stress of a situation like the death of a loved one, divorce, or abuse, the brain may strengthen or weaken connections between nerves to form new neural connections. Over time, chronic stress can diminish brainpower, reducing overall nerve growth and memory to shift resources to enable elevated fear responses and enable humans to survive.

Stress activates the "fight-or-flight" response when we face threats, a reaction that can help keep us alive.

Protect employees from chronic stress

Burnout doesn’t just affect employees’ health. It also increases turnover, reduces productivity, and leads to illness. What kinds of changes can employers make to reduce burnout in the workplace? This white paper encourages employers to modify their cultures to reduce burnout, including offering clear feedback and support, creating more flexible workplaces, and reducing unreasonable workloads.

Exercise improves brain blood flow, stimulates neural growth, and more.

How we frame stress—as good or bad—seems to alter how it affects us

This podcast discusses research that indicates stress perception may drastically affect how we respond to it. In research exploring if our stress is presented as diminishing our health versus if we're told it enhances our performance, it will lead to differences in how successful participants are at performing tasks—with the enhancers doing better.

Our ancient fight-or-flight response may contribute to modern ailments

Many common modern diseases humans struggle with may in fact have their origins in our ancient fight-or-flight stress response. Long-term effects of the stress hormones cortisol and adrenaline—in this case, triggered by things like workplace stressors—can wreak havoc on the delicate internal balance of our organ systems.

The brain will attempt to rest itself in periods of chronic sleep deprivation

Skimping on sleep lengthens reaction times and blunts decision-making skills. At a certain point, the brain will try to sneak sleep where it can, shifting sections offline even as you remain awake. Going without sleep raises blood pressure, undermines the immune system, and increases one's risk of dementia.

These areas of the brain are hard-hit in depression—but the changes are reversible

Depressed brains can have certain characteristic changes, including an overactive amygdala, reduced hippocampus size, and changes to the thalamus and neuromodulating chemicals in the brain.

Key symptoms of burnout can be both mental and physical

Burnout can be accompanied by several symptoms, including low energy and chronic fatigue, trouble concentrating, difficulty sleeping, and depression. It may even manifest physically as musculoskeletal pain, headaches, stomach and intestinal pain, and more. More intense cases have been linked to cardiovascular and mental health disorders.

Links between long-term caregiving and chronic stress

This Cleveland Clinic overview suggests that around 60% of people caring for family or loved ones with health conditions will experience burnout. Caregivers prepare meals, help with transportation, administer medications, and perform daily tasks for others, all while managing their own lives. This guide may help readers overcome the guilt or frustration of long-term caregiving to seek alternative options.

Stress can be contagious—and scientists want to learn more about it

Researchers have shown that being around someone who is stressed can trigger a stress response in your body, such as elevated cortisol levels and elevated heart rate. One way this was recently studied was by having people watch stressful activities, like a recorded job interview or solving challenging math problems, and then sampling hormones in observers' spit.

The biology of stress in your body

Stress is a normal human response that has evolved over millions of years to handle changes or threats in our environment. This article is a helpful overview of the biological basics of this response. While it is not harmful to our physiology in the acute setting, chronic stress can lead to damaging changes in the human body over many years.

Self-care can't fix burnout on its own

Steps such as exercise, breathing, mindful eating, and spending time with friends, can help alleviate the fight-or-flight mode response of the body to alleviate stress, but they don't fix the stressors causing the burnout. To address those, workplaces may need to consider how to better manage workloads and duties.

How aging degrades neural functioning in the brain over time

Aging affects the brain perhaps more than any other organ in the body. Throughout life, the brain experiences radical shifts in the number of neurons, synaptic connections between neurons, and hormone levels that regulate our mood and processing.

Stress contributes to gray hair because when the body experiences stress, the sympathetic nervous system releases specific hormones that influence pigment-producing cells.

Stress affects different animals in different, but useful, ways

Animals feel stress when they experience actual dangers—such as a zebra chased by a lion. Humans often feel stress from worries, memories, or even thoughts about problems that may occur in the future. For this reason, animals tend to experience stress in short, intense bursts. Conversely, people can feel stressed for long periods, which can eventually be harmful to their health.

Exercise releases chemicals that enhance cognitive function

Neurotransmitters like dopamine, serotonin, and norepinephrine, along with increased brain-derived neurotrophic factor levels, enhance a wide range of brain functions. New research demonstrates a direct link between movement and numerous cognitive benefits, including memory, learning, and stress resilience.

The positives of feeling stressed

Worrying about past events and upcoming challenges is not a pleasant experience, but a reasonable amount of stress can bring a lot of good into our lives. In this episode of "The Happiness Lab" with Dr. Laurie Santos, two psychology experts offer tips for resetting one's relationship with stress. Listen and learn how to make stress a positive tool rather than a debilitating emotion.

ADHD impairs working memory and limits the ability to form long-term memories

While ADHD is most often recognized for producing struggles with attention and organization, these executive functions are critical for capturing the data that creates memories in the brain. Breaking data into pieces, or chunking, helps address these struggles.

How stress affects every organ in the body

If you are a visual learner, this resource is for you. Not only does this article from the World Economic Forum outline the causes of modern stress along with helpful strategies, but they have created an approachable infographic to show exactly how stress manifests throughout our different bodily systems. Pair this visual guide with our other resources to gain a deep knowledge of stress and the human body.

Chronic drug use can cause neurological changes in the brain

Neuroscientist Judy Grisel breaks down the biology of addiction, examining how drugs hijack the brain’s natural reward system and create lasting neural changes. The physiological and neurological impacts of chronic drug use require a multifaceted treatment approach.

Easy resets for stress reduction

Individual solutions for burnout, often called “self-care,” can be helpful for managing stress. Harvard researcher Aditi Nerurkar’s 2024 book The Five Resets details a road map for burnout recovery. In this interview she suggests, among other tactics, gaining focus on what matters the most in one’s life, taking breaks from both work and the internet, and making time for practices that strengthen the mind-body connection.

Age, stress, and neurological disorders can prevent memory formation and recall

Neurons transmit signals between one another at sites called synapses. Repeated interactions at these sites improve the efficiency of signal transmissions, making memories involving sensory data associated with those neurons easier to recall. Biochemical factors impacting these synaptic interactions affect memory quality.

Some types of stress (eustress) have positive benefits

While many perceive stress as solely negative, stress can in fact be divided into two categories: distress (negative stress) and eustress (positive stress). Moderate levels of stress are positive in that they can boost motivation and promote resilience, which have positive mental health benefits.

Burnout became a serious area of study in the 1970s

Psychology professor Christina Maslach developed the first tool to assess the presence of burnout, focusing on six contributing factors within workplaces: an overwhelming workload, a lack of control over one’s work, insufficient reward for one’s efforts, interpersonal conflict, a sense of unfairness, and a mismatch between individual and organizational values.

Workplace overload has spawned the industry of 'burnout coaches'

Chronic stress and burnout aren't just leading to mental-health crises. They're also the foundation of a new career type: burnout coach. These aren't necessarily licensed therapists, but often people who have been through the burnout cycle and received certification as coaches. (Some users may experience a paywall.)

How burnout creep has spread across various areas of life

Burnout primarily refers to the feeling of being overwhelmed at work and is officially considered an occupational hazard, but colloquially people have started referring to other areas of burnout, including workouts or television shows.

Left versus right brain strokes vary significantly in long-term effects

Due to the high complexity of the brain, the aftereffects of a stroke can have widely different manifestations, ranging from minor temporary impairments to rapid death. Whether a stroke results in paralysis, speech impairments, loss of bodily function, or death will depend on whether it occurs in the left or right hemispheres or the brain stem.

Sleep disorders can exacerbate neurological and other health conditions

Brain regions that control sleep sit adjacent to those that regulate the autonomic nervous system, which controls involuntary bodily functions like heart and breathing rates. These neighbors influence each other, meaning poor sleep can impair or negatively impact the ANS, further disturbing sleep.

How do anxiety and stress differ?

This article explains that though “stress” and “anxiety” are often used interchangeably, there are distinct differences between the two. Stress is defined as the body's response to an external trigger and can be classified as acute or chronic. Anxiety, however, tends to be triggered internally by excessive thoughts and judgement. Whereas stress disappears when the trigger is gone, anxiety tends to stick around. If left unchecked, both can escalate into more severe mental health conditions.

One-third of early- and mid-career workers have considered quitting due to stress

In 2024, around half of all full-time employees polled by the National Alliance on Mental Illness reported experiencing burnout at their jobs. Around a third of all employees ages 18 to 49 had considered quitting their jobs due to workplace stress.

Consuming true crime media can increase stress and anxiety and create a false sense of danger.

Too little stress can also harm our health because mild or moderate stress—followed by recovery—helps make us resilient.

The WHO defines burnout as an occupational phenomenon

While it’s not a medical condition, the World Health Organization defines burnout as an occupational phenomenon in the International Classification of Diseases (ICD-11), and considers it separate from general stress.

How depression affects the brain

Treatment for depression has historically hinged on the theory that the condition was caused by underactive or abnormal neurotransmitters, specifically serotonin and norepinephrine. This four-minute video by Yale Medicine details how these neurotransmitters didn't explain the symptoms of depression but, two other neurotransmitters involved in regulating mood and emotion did. GABA and glutamate, some of the brain's most plentiful neurotransmitters, may possibly be the source of depressive symptoms.

The second phase of acute stress: the 'slow' response

The body's reaction to acute stress involves two responses: fast and slow. The first occurs immediately, with the central nervous system triggering the release of adrenaline. The second releases cortisol, which elevates blood sugar and blood pressure and restricts nonessential functions like digestion and the immune system.

Recognizing the 12 steps of workplace burnout

Psychologists Herbert Freudenberger and Gail North created a 12-stage model to explain the path to burnout. It begins with employees feeling the drive to prove themselves in the workplace, leading to overwork and neglecting of one's needs, and ends with depersonalization and depression.

Drug tolerance and withdrawals are consequences of overloading dopamine circuits

Addictive substances or behaviors will typically flood our brains with more dopamine than usual. In response to the overstimulation, our brains will decrease the number of available dopamine receptors. This results in the need for more stimulus for the same response (tolerance) and a rise in negative feelings when the stimulus is absent (withdrawal).

How artificial intelligence, which detects patterns, can identify burnout

Researchers are training AI to detect stress-related symptoms, helping physicians and other medical workers recognize and reduce stress from overwork and potentially avoid burnout.

People are experiencing AI 'brain fry' at work

Workers, particularly in marketing, are experiencing mental fatigue in the workplace due to expectations—often unspoken—that they should use AI to multitask beyond their comfort levels. Many feel they are underperforming if they don't embrace this technology. This situation differs from typical burnout. This podcast discussion suggests that this "brain fry" tends to intensify when employees are required to use more than three AI tools.

Psychedelics set off a flurry of brain activity that may permanently alter it

The brain seems to experience a sharp increase in communication between areas that generally don't interact. New research suggests a thin, sheet-like gray matter structure tucked deep within the brain, between the insular cortex and striatum, may be the key to this change. The area is centrally located and home to many of the receptors that psychedelics target, potentially rewiring the brain and rewriting thought patterns.

Music that builds to a crescendo and then resolves relieves stress more than listening to nature sounds.

The two phases of stress: fast and slow

The physiological response to acute stress generally involves two phases—the "fast" response in which adrenaline is released, and a second "slow" response in which cortisol is released. This technical resource reviews what happens in the body during each phase.

Depression changes the brain, causing distinct structural alterations visible on brain scans, but effective treatment can eventually make a depressed brain resemble a healthy one.
