Anyone who’s experienced even a mild amount of anxiety understands how draining it can be. Even a few anxious minutes can leave you feeling exhausted and ready for a nap. Turns out, there’s plenty of science-backed reasons to explain this phenomenon. 

Here, we explore exactly why anxiety is so tiring, how you can boost your energy levels if your worries are leaving you drained, and when it might be time to seek professional help.

How does anxiety contribute to fatigue and tiredness? 

Anxiety’s impact on the body is significant. In addition to making it hard to get quality rest, anxiety causes chemical changes in your body that can contribute to overall fatigue and leave you tired all the time.

Sleep disturbances

One of the main symptoms of anxiety, and of many anxiety disorders, is sleep problems. For many people, racing thoughts and constant worry are difficult or impossible to “turn off” at night when it’s time to sleep. 

Regular sleeplessness can, of course, contribute to fatigue. It’s unsurprising, then, that tiredness is a very common symptom of anxiety. Unfortunately, a lack of sleep, or poor sleep quality, can also make anxiety worse, leading to a negative feedback loop that can be difficult to break. 

Stress response 

Anxiety can trigger the body’s “fight-or-flight" response—an activation of the nerves of the sympathetic nervous system. “Fight or flight” is a complex biological process meant to ready our bodies to respond to threats by raising blood pressure and heart rate, slowing down digestion, and flooding the body with stress hormones like cortisol and adrenaline.

Unfortunately, chronic, long-term anxiety can mean locking your body in “fight-or-flight.” Unless you can release this state by activating the parasympathetic nervous system, it’s difficult to calm down and relax. This constant physical stress can lead to physical symptoms like fatigue and exhaustion, as well as muscle tension and brain fog. 

What about “adrenal fatigue”?

If you’ve researched the effects of stress and anxiety on the body, you may have come across the term “adrenal fatigue.” “Adrenal fatigue” is not an accepted medical diagnosis since there is no scientific proof that supports adrenal fatigue as a medical condition. 

The phrase is used by some people to describe a collection of vague symptoms—including fatigue, body aches, digestive problems, and sleeplessness—linked to chronic stress. The theory behind “adrenal fatigue” is that chronic stress limits your adrenal glands’ ability to produce adequate amounts of the hormones needed to keep you feeling well. 

If you’re experiencing any of the symptoms listed above, the best course of action is to consult your primary care physician. They can do a full assessment of your symptoms. If your PCP suspects your symptoms may be related to a mental health condition, they may suggest a referral to a psychiatrist, who will discuss treatment options, including medications and/or supportive therapy.

How can you manage fatigue from anxiety? 

If you’re suffering from fatigue caused by anxiety, there’s a number of changes you can institute to help your energy levels.

Practice good sleep hygiene 

All those tips you’ve heard a million times about “good sleep hygiene”? Turns out, there’s something to them. Setting a consistent sleep and wake schedule, avoiding screens for a set period of time before bed, and avoiding large meals, alcohol, and caffeine before bed can all contribute to a longer, more restful night’s sleep. Overhauling your nighttime routine can feel daunting. Start with just one change, like going to bed and waking up at the same time each day, and go from there.

Although the sleep needs of adults vary, most experts agree that aiming for 7-9 hours is appropriate

Try relaxation techniques 

If you constantly find yourself unable to relax thanks to anxiety, it might be worth trying out some tried-and-true relaxation techniques. These can be especially effective at turning off your “fight or flight” response and activating your body’s parasympathetic nervous system—the network of nerves that helps you relax and rest. 

Proven techniques that can help ease anxiety include: 

  • Grounding techniques: coping strategies that can help bring you back into the present moment, i.e., ground you., by offering a mental distraction and snapping you out of “fight-or-flight.”
  • Deep breathing exercises: which can calm you and help activate your parasympathetic nervous system, which helps your body relax.
  • Mindfulness meditations: which involves focusing on your breathing as a way of bringing your mind’s attention to the present moment without worrying about the past or future.

Get moving 

We know, we know—if you’re already tired, how is exercise going to help? Turns out, regular exercise has been demonstrated to be protective against anxiety and other health problems. And one study found that even a single yoga session can help ease anxiety when it hits. That means you’re more protected from the depleting effects of anxiety, leaving you with less fatigue. 

Plus, exercise itself can be energizing. It boosts mitochondria production in your cells, which may increase your overall energy, and increases your overall oxygen circulation, which can leave you feeling more alert. It doesn't have to be high intensity, either. Any sort of physical activity—including simply heading outside for a quick walk—can have positive effects. 

Consult a professional 

If these tips aren’t enough to boost your energy levels, and you constantly find yourself feeling exhausted thanks to anxiety, it might be a sign to seek professional treatment. Up to 30% of Americans will suffer from an anxiety disorder, like generalized anxiety disorder (GAD) or social anxiety disorder, at some point in their lives, making anxiety disorders the most common mental health conditions in the country. If your anxiety is causing symptoms severe enough to disrupt your quality of life and general well-being, help is available.

If you’re living with an anxiety disorder, extra support—with medication, talk therapy (like cognitive behavioral therapy), or both—may be necessary to control your symptoms. While therapists use talk therapy to help you overcome your symptoms, psychiatrists can prescribe you medications to manage your condition. Most people with anxiety disorders will benefit from a treatment plan that combines medication and supportive therapy.
