Signs That Your Anxiety Could be Making You Tired and Weak

Author: Ari Whitten


Normal Tiredness vs. Anxiety-Induced Fatigue

The American Psychological Association (APA) defines anxiety as “an emotion characterized by feelings of tension, worried thoughts and physical changes like increased blood pressure.”

Anxiety generally revolves around work, health, finances, and other issues that demand a person’s attention. Small amounts of stress can be beneficial, such as being worried about being hit by a car, which means that a person will instinctively look both ways before crossing the street, thus ensuring their safety. But sometimes the duration or severity of an anxious feeling can be out of proportion to the original trigger, or stressor. This results in symptoms that include restlessness and feelings of being “on-edge,” uncontrollable worry, increased irritability, concentration difficulties, and sleep problems, such as problems falling or staying asleep or, overall, getting enough sleep.1 All these contribute to feelings of anxiety and extreme fatigue.

Stress-Induced Anxiety Side-Effects

 Stress and anxiety share many common symptoms, and chronic stress causes tension. There are about 16 mechanisms by which stress can affect your energy levels, and understanding these are vital in finding a solution to your extreme fatigue.

Stress Depletes The Endocannabinoid System

This is a system in your brain, which is responsible for shutting down the body’s stress response and re-establishing homeostasis. 2 When the Endocannabinoid System is depleted, we can no longer ward off fear and anxiety and stress becomes chronic, which allows fatigue to set in.

Throws Off Neurotransmitters In The Brain

Stress results in imbalances of serotonin, dopamine, and acetylcholine. 3 4 Low levels contribute to depression, anxiety, binge eating, addiction, lethargy, apathy and anhedonia (inability to take pleasure in life). Chronic stress can also cause GABA resistance. 5 GABA is an inhibitory neurotransmitter that promotes relaxation and rejuvenation. When the brain’s sensitivity to this neurotransmitter is reduced it impacts your mental health and you have racing thoughts, fears, anxiety disorders, tension, and poor sleep. This again, contributes to lack of energy.

Decreases Thyroid Hormones

A proper functioning thyroid is essential in energy production, cognitive function, and muscle function.

HPA Axis Dysfunction 

This is the interaction between the hypothalamus-pituitary and adrenal glands. When you are chronically stressed (and the endocannabinoid system is depleted), the HPA Axis becomes chronically activated and starts to dysfunction. It becomes resistant to the negative feedback loops that try to calm the system and is associated with numerous medical conditions including CFS, Fibromyalgia, IBS, Depression, Bipolar Disorder, ADHD, PTSD, SAD, and even Alzheimer’s and Diabetes. 6 7 8

Lowers Your Intelligence 

Stress can shut down centers in the Prefrontal Cortex, which are responsible for higher thought processes. This, in turn, results in poor self-control and lifestyle choices.

Makes You Hungry And Increases Sugar Cravings

When you eat a diet consisting of high glycemic processed food, lower in protein, and fiber results in inflammation, which directly suppresses the neurotransmitter Orexin (which is crucial in regulating wakefulness and energy levels). 910 Ironically, energy drinks especially sap your energy levels and may induce symptoms of anxiety such as increased heart rate and muscle tension.

Chronic Inflammation 

Inflammation is partly regulated by the stress hormone cortisol. But over time, chronic stress reduces the effectiveness of cortisol, and inflammation gets out of control. 11 Chronic inflammation is linked to almost every disease from heart disease and cancer to depression and Alzheimer’s. It also has a direct impact on energy levels by shutting down Orexin.

Suppresses The Immune System 

A poor functioning immune system makes us more susceptible to infections. 12 

Disrupts Your Circadian Rhythm And Sleep

The key cause of fatigue for most people is not getting a good night’s sleep. When the quality and hours of sleep are affected, it leads to chronic sleep deprivation and may result in other issues such as depression, symptoms of anxiety, weight gain, daytime sleepiness, and fatigue as well as increased rates of dozens of diseases. 13 14

Increases Depression

Depression Concept

 Mood and energy are very much intertwined. Better moods facilitate better energy and vice versa. Chronic stress also causes energy regulating areas of your brain to atrophy. 15

Causes Chronic Physical Pain 

By changing the structure and function of your brain in profound ways, making it more and more sensitive to sensations of pain. The pain itself then causes more stress resulting in a vicious cycle of pain, stress, and chronic fatigue syndrome. 16 17.

Lowers Beneficial Hormones 

Including pregnenolone, which is a precursor to both stress and sex hormones. When stress is chronic, your adrenals “steal” pregnenolone away from the production of sex hormones. 18 This results in inflammation, poor mood, higher stress and anxiety, and lower energy levels.

Damages Your Mitochondria 

By causing oxidative damage when Mitochondria are damaged, it directly lowers our cell’s capacity to produce energy. 19

Leaky Brain Barrier 

By causing immune cells to release histamine and various inflammatory compounds. These chemicals increase the permeability of the blood-brain barrier allowing substances that do not typically enter the brain to enter. 20

Flushes Out Beneficial Minerals From The Kidneys 

This included potassium and magnesium, which most of us are already deficient in. Potassium and magnesium are essential for hundreds of metabolic processes in the body, and depleting these minerals can result in numerous problems, including fatigue, muscle breakdown, heart palpitations, and poor detoxification.

Induces A Leaky Gut

Also known as increased gut permeability, 21 this increases the amount of bacterial toxin (endotoxin) entering the bloodstream and causing inflammation, which, as you now know, directly shuts down Orexin and decreases your energy levels. Leaky gut can also cause food sensitivities and intolerances, IBS, SIBO (small intestinal bacterial overgrowth), and gut pain 22 23.

What You Can Do to Stop Tiredness

Now that you understand how living with anxiety causes fatigue, it is important to learn what lifestyle changes you can do to overcome stress and get your energy back. Six powerful stress management strategies are outlined below:

Minimize Or Eliminate Stimulants Such As Caffeine And Nicotine 

It has been scientifically proven that stimulants such as caffeine have numerous health and disease prevention benefits. However, chronic use can be counterproductive. If you are already stressed, caffeine will further stimulate the stress response system resulting in neurotransmitter resistance. 

Caffeine works to increase energy by blocking the neurotransmitter Adenosine, which normally calms the brain and relaxes you, thus causing an energizing effect. When you drink caffeine every day, the brain feels overstimulated and produces negative feedback adaptations to counter this and calm you back down. Over time, this lowers your baseline level of mood, performance, and energy. If you are currently addicted to caffeine, start weaning yourself off slowly and gradually (so as to avoid withdrawal symptoms). 

Despite initially feeling a little tired, this will be worth your efforts and is the first step in overcoming stress and anxiety.

Lower Your Sensory Load 

In the modern world, we are constantly bombarded by flickering lights, rapidly changing sights and sounds, social media, phones, TV, music, background noise, movies, games, etc. All these things are foreign to our biology and tax our brain in a way that has never been taxed before.

To cope and try and calm itself down, the brain increases the inhibitory neurotransmitters, Serotonin, and GABA, but overtaxing these systems results in burn out and neurotransmitter imbalances. 

If you are always on the go, listen to loud, aggressive music while driving or exercising, stare at a computer monitor (which though you may not realize it, constantly flickers) or TV screen for most of your workday or if you are indoors under artificial light for most of the day then you need to lower the stimuli to your sensory organs.

First of all, do not watch the news or fast-paced or violent movies within 1 hour of bedtime. Make sure you take small 5 minute breaks throughout your day, doing something you enjoy. Finally, get outside, preferably into nature for at least 30 minutes a day.

Optimize Your Circadian Rhythm And Sleep 

As blue light entering your eye after sunset decreases your production of Melatonin (an important hormone responsible for regulating your sleep/wake cycle and also a master antioxidant) and in turn disrupts your Circadian Rhythm, it is important to expose yourself to sunlight during the day and minimize your exposure to blue light at night. Firstly, wear blue light blocking glasses for at least 1hour (but preferably 2-3 hours) before bedtime. One of the best brands of blue light blocking glasses is SafetyBlue Sleep Saviour, which can be found on Amazon.

Make sure you also wear your glasses when watching TV after sunset. Secondly, download f.lux or Twilight apps on your computer, tablet, and/or smartphone. These free apps automatically lower the blue light emissions from your device after sunset. Thirdly, get incandescent, red, or amber colored light bulbs for a few lights in your house, in areas you spend time in at night, and also for your bedroom and bathroom. After sunset, make sure you only use these lights.

Incorporate Re-Charge Rituals Into Your Daily Life

These are predetermined periods of the day where you engage in consciously cultivating the kinds of brain performance habits you want (ones that build energy, focus, laughter, play, and gratitude). There are three types of rituals you should implement: a morning ritual, a nighttime ritual, and brief rituals interspersed throughout the day (ideally for about 1-5 minutes every hour). How you start and end your day teach your brain how to behave and reinforce the right neural circuits that help you focus, relax, and enjoy love and happiness. 

Some powerful re-charge rituals include mindfulness, meditation, prayer, deep breathing, laughter, positive social relationships, resistance breathing and breathing exercises, cold exposure, singing or chanting, dancing, music and sound therapy, yoga, exercise, massage, tai chi, acupuncture, spending time in nature, napping, power postures, sunbathing and hobbies. It’s important to identify which of these work for you personally and start building a daily practice. These rituals are incredibly powerful when practiced daily.



 Meditation is a must-do when it comes to overcoming stress. The benefits of meditation are well documented and backed by a mountain of evidence. It is, by far, one of the most powerful medicines available to humans and can help reduce mental health symptoms. 

Meditation can decrease stress 24, decrease anxiety 25, decrease feelings of loneliness 26, improves your ability to regulate mood and emotions 27, decrease anxiety symptoms and make you happier 28 29 30 decrease pain 31, decrease inflammation 32, increase your sense of connection to others 33, improve cognitive performance 34 35 and literally re-shapes your brain in beneficial ways 36 37 38

Rebuild And Balance Your Endocannabinoid System 

This is important to get your body to calm down and enter rest and relaxation mode.

First and foremost, you need to de-stress by following the recommendations above.

Second, optimize your intake of Omega 3 fatty acids, which are linked to the endocannabinoid system and protect your brain cells from damage and inflammation.39 If you supplement with Omega 3’s, take Krill oil with high-dose astaxanthin (which is in itself a powerful neuroprotective and anti-inflammatory compound).

Third, double or triple the amounts of dark green leafy veggies you eat each day. In fact, you should aim to have greens with every meal. Greens are a great source of beta-caryophyllene, which is a phytocannabinoid that has a powerful effect on the endocannabinoid system.

Fourth, cut down on alcohol, as alcohol can throw the endocannabinoid system out of balance.

Fifth, use massage, acupressure mats (or acupuncture), and self-myofascial release. These also help balance the endocannabinoid system.

Lastly, use CBD (Cannabidiol), which is a powerful endocannabinoid signaller found in marijuana and hemp plants (note, this is legal and does not contain any psychoactive compounds). Hundreds of studies have shown that CBD can benefit human physiology. If you suffer from chronic stress, CBD is one of the most beneficial compounds in existence, as it is a powerful anti-anxiety and anti-stress cannabinoid signaling compound. Oral intake of CBD is best, and Bluebird Botanicals is a highly recommended brand.


As you have probably realized from the above, fatigue is very complicated health condition and involves multiple pathways and systems. Most people assume their fatigue is a result of “ adrenal fatigue,” but it is much more complicated than that. 

If anxiety is causing your fatigue to use some of the powerful strategies outlined above. A whole system-based approach is necessary to really make a difference and create a positive upward spiral of low stress, low inflammation, positive mood, resistance to infection, and healthy mitochondria.
