Episodes of Extreme Fatigue
Episodes of extreme fatigue and exhaustion, such as having periods of severe fatigue, low energy, and feeling completely worn out are common symptoms of anxiety, including anxiety and panic attack symptoms.
The vast majority of anxious people experience episodes of extreme fatigue and exhaustion.
This article explains the relationship between anxiety and episodes of extreme fatigue.

Episodes of Extreme Fatigue Common Symptom Descriptions
- You experience episodes of extreme fatigue, exhaustion, feeling super tired, or feeling burnt out or worn-out.
- You experience sudden and out-of-the-blue episodes of feeling extremely exhausted, and so much so, that you feel like you can barely function.
- You experience episodes of feeling so tired you feel ill.
- You have episodes of feeling so tired that you can barely get out of bed.
Episodes of extreme fatigue can:
- Occur occasionally, frequently, or persistently.
- Precede, accompany, or follow an escalation of other anxiety symptoms or occur by itself.
- Precede, accompany, or follow a period of nervousness, anxiety, fear, and stress, or occur "out of the blue" for no reason.
- Range in intensity from mild, to moderate, to severe.
- Come in waves where it’s strong one moment and eases off the next.
- Occur for a while, subside, and then return for no reason.
- Change from day to day, moment to moment, or remain as a constant background during your struggle with anxiety disorder.
This symptom can seem more noticeable when undistracted, resting, trying to sleep, or waking up.
All the above combinations and variations are common.
For information on chronic fatigue, see the “Chronic fatigue” symptom.
To see if anxiety might be playing a role in your symptoms, rate your level of anxiety using our free one-minute instant results Anxiety Test, Anxiety Disorder Test, or Hyperstimulation Test.
The higher the rating, the more likely anxiety could be contributing to or causing your anxiety symptoms, including feeling like impending doom symptoms.

Causes
Medical Advisory
Talk to your doctor about all new, changing, persistent, and returning symptoms as some medical conditions and medications can cause anxiety-like symptoms.
Stress, including anxiety-caused stress
Anxious behavior, such as worry, activates the stress response, which secretes stress hormones into the bloodstream, where they travel to specific locations to immediately prepare the body for emergency action – to fight or flee. This instinctual survival reaction is often referred to as the Fight Or Flight Response.[1][2]
Visit the “Stress Response” article for the many ways it can affect the body.
Some of the stress response changes include:
- Quickly converts the body’s energy reserves into “fuel” (blood sugar) to provide an instant boost of energy.
- Increases heart rate, respiration, and metabolism due to the boost in energy.
- Stimulates the sympathetic nervous system, increasing nervous system activity to be more sensitive and reactive to danger.
- Heightens most of the body’s senses to be more aware of danger.
- Increases activity in the amygdala (the brain’s fear center) and decreases activity in the pre-frontal cortex (the rationalization area of the brain) so that our attention is focused on the threat and away from thoughts that could be distracting.
- Shunts blood to parts of the body vital to survival, such as the brain, arms, legs, and vital organs, and away from parts less vital for survival, such as the stomach, digestive system, and skin. It accomplishes this by constricting blood vessels in certain parts of the body and dilating them in others.
- Tightens muscles to make the body more resilient to injury.
- Increases respiration to accommodate the increase in heart rate.
- Increases perspiration to keep the body cool and expel toxins.
These are just a few of the changes caused by the stress response.
Since stress responses push the body beyond its balance point, stress responses stress the body. As such, anxiety stresses the body.
Stress taxes the body’s energy reserves much harder than normal. As such, we can become fatigued more easily.
Stress is a common cause of acute episodes of fatigue.
Moreover, when stress occurs to frequently, the body can become stress-response hyperstimulated (chronically stressed).[3][4]
Hyperstimulation can cause the changes of an active stress response even though a stress response hasn’t been activated.
Visit our “Hyperstimulation” article for more information about the many ways hyperstimulation can affect how we feel.
Hyperstimulation is a common cause of chronic episodes of extreme fatigue.
Furthermore, when the body is continually hyperstimulated, it can behave erratically, including causing erratic swings of energy, such as from feeling super-energized to feeling completely exhausted.[4]
Some episodes of depleted energy can be so pronounced that even menial tasks can seem too exhausting to manage.
In addition to the many problems that hyperstimulation-caused exhaustion can cause, it can also disrupt meaningful rest and sleep.
Hyperstimulation-caused fatigue is often not “good” fatigue that allows the body to rest but “nervous” fatigue that makes it difficult to rest.
Being devoid of energy and not being able to rest or sleep can set up a vicious cycle of being exhausted yet unable to gear down enough to adequately re-energize.
See our symptom “Tired But Wired” for more information.
Other Factors

Treatment
When this symptom is caused or aggravated by other factors, addressing those factors can reduce and eliminate episodes of extreme fatigue.
When this symptom is caused by an anxiety-triggered stress response, calming yourself will end the active stress response and its changes. Episodes of extreme fatigue will subside as your body recovers from the active stress response.
Keep in mind that it can take up to 20 minutes or more for the body to recover from a major stress response. But this is normal and shouldn’t be a cause for concern.
When this symptom is caused by hyperstimulation, eliminating hyperstimulation will end this anxiety symptom.
You can reduce and eliminate hyperstimulation by:
- Containing anxious behavior.
- Reducing stress.
- Regular deep relaxation.
- Relaxed diaphragmatic breathing.
- Regular light to moderate exercise.
- Getting regular good sleep.
- Eating a healthy diet of whole and natural foods.
- Avoiding stimulants.
- Passively-accepting your symptoms until they subside.
- Being patient as your body recovers.
Visit our “60 Natural Ways To Reduce Stress” article for more ways to reduce stress.
Recovery Support members can read chapters 5,6, 7, and 14 for more ways to reduce stress.
As the body recovers from hyperstimulation, it stops sending symptoms of hyperstimulation, including episodes of extreme fatigue.
However, eliminating hyperstimulation can take much longer than most people think, causing symptoms to linger longer than expected.
Acceptance, practice, and patience are key to recovery.
Short-term remedies:
Even though eliminating hyperstimulation will eliminate chronic anxiety symptoms, including episodes of extreme fatigue, some people have found the following strategies helpful in reducing episodes of this symptom in the short term.
However, keep in mind that each person can have a unique symptom experience since each person is somewhat physically, chemically, psychologically, and emotionally unique. What might work for one person might not for another.
Reduce stress – Since stress, including anxiety-caused stress, is a common cause of episodes of extreme fatigue, reducing stress can reduce episodes of this symptom.
Any stress reduction strategy can help improve this symptom. Visit our article “60 Ways To Reduce Stress And Anxiety” for natural stress reduction strategies.
Recovery Support members can read chapters 4 and 14 for many natural ways to reduce stress and anxiety.
Regular good sleep – Regular good sleep can reduce stress, cortisol, and the body’s overall level of stimulation. Their reduction can reduce and eliminate anxiety symptoms, including this one.
Regular deep relaxation – Deep relaxation reduces the body’s overall level of stimulation and stress, leading to a reduction in anxiety symptoms, including this symptom.
Regular light to moderate exercise – Regular light to moderate exercise can reduce stress and use up excess cortisol, which can help reduce anxiety symptoms, including this one.
Avoid stimulants – Stimulants, such as caffeine, stimulate the body by increasing the circulation of cortisol, the body's most powerful stress hormone. To help the body recover from hyperstimulation, we need to reduce the production of stress hormones and stimulation, not increase it. A reduction in stress and stimulation can help reduce symptoms of hyperstimulation, including episodes of extreme fatigue.
Contain your anxiousness – Since anxiety activates the stress response, which causes anxiety and hyperstimulation symptoms, containing your anxiousness about this anxiety symptom can help reduce and eliminate it, even in the short term.
The more successful you are in containing your anxiousness, the more opportunity your body has to reduce stress and stimulation. A reduction in stress and stimulation can reduce episodes of extreme fatigue.
Keep well hydrated – Dehydration can cause anxiety-like symptoms and aggravate existing anxiety symptoms. Keeping your body well hydrated can reduce and eliminate anxiety symptoms, including this one.
Recovery Support
The Recovery Support area of our website contains thousands of pages of important self-help information to help individuals overcome anxiety disorder, hyperstimulation, and symptoms.
Due to the vast amount of information, including a private Discussion Forum, many of our Recovery Support members consider it their online recovery support group.
Therapy
Unidentified and unaddressed underlying factors cause issues with anxiety. As such, they are the primary reason why anxiety symptoms persist.
Addressing your underlying factors (Level Two recovery) is most important if you want lasting success.
Addressing Level Two recovery can help you:
- Contain anxious behavior.
- Become unafraid of anxiety symptoms and the strong feelings of anxiety.
- End anxiety symptoms.
- Successfully address the underlying factors that so often cause issues with anxiety.
- End what can feel like out-of-control worry.
All our recommended anxiety therapists have had anxiety disorder and overcame it. Their personal experience with anxiety disorder and their Master's Degree and above professional training give them insight other therapists don't have.
If you want to achieve lasting success over anxiety disorder, any one of our recommended therapists would be a good choice.
Working with an experienced anxiety disorder therapist is the most effective way to treat anxiety disorder, especially if you have persistent symptoms and difficulty containing anxious behavior, such as worry.[5][6][7]
In many cases, working with an experienced therapist is the only way to overcome stubborn anxiety.
Research has shown that therapy is the most effective treatment for anxiety disorder, and distance therapy (via phone or the Internet) is equally, if not more effective, than face-to-face in-person therapy.[8][9][10]
