The Many Causes of Fatigue (and What You Can Do About Them)

Dec 7, 2022

We’ve all been there—you’re dragging yourself through the day, struggling to keep your eyes open, and feeling like you could fall asleep at any moment. Fatigue is a common issue, but it can also be a sign of something more serious. 

Experts estimate that anywhere from 836,000 to 2.5 million Americans suffer from Chronic Fatigue Syndrome, and 90% of people with Chronic Fatigue Syndrome go undiagnosed.  

Let’s explore some of the most common causes of fatigue and some supportive measures you can take to alleviate it!

  • Lack of Sleep

    • This one might seem obvious, but it’s worth mentioning because it’s such a common cause of fatigue. If you’re not getting enough sleep, you’re going to be tired! The National Sleep Foundation recommends that adults get 7-9 hours of sleep per night. If you’re not hitting that mark, it might be time to reassess your sleep habits. Consider cutting back on caffeine and screens before bed, setting a regular sleep schedule, and creating a relaxing bedtime routine.

  • Dehydration

    • Dehydration can also lead to fatigue. When you’re even slightly dehydrated, your body must work harder to function properly, which can leave you feeling exhausted. Make sure you’re drinking plenty of water throughout the day—aim for half your body weight in ounces each day! —and cut back on diuretics like caffeine and alcohol.

  • Poor Nutrition

    • What you eat also plays a role in how you feel. If you’re not eating enough or getting the right nutrients, you can feel the effects in the form of fatigue. Make sure you’re eating a well-rounded diet with plenty of fruits, vegetables, and protein. And don’t forget those essential vitamins and minerals! A daily multivitamin can help ensure that your body is getting everything it needs to function at its best.

  • Anemia

    • Anemia is a condition in which your blood doesn’t have enough healthy red blood cells. Red blood cells are responsible for carrying oxygen to your tissues, so if you don’t have enough of them, your body isn’t getting the oxygen it needs to function properly. This can lead to fatigue, shortness of breath, and other symptoms. If you think you might be anemic, talk to your health care practitioner—anemia is usually easily treated with iron supplements and supportive dietary measures, but it is always important to address the underlying cause of the anemia.

  • Stress

    • Stress is another common cause of fatigue. When you’re stressed out, your body goes into “fight or flight” mode, releasing hormones like adrenaline and cortisol. This can lead to increased heart rate and blood pressure as well as feelings of anxiety—and all that takes a toll on your energy levels. If stress is causing your fatigue, there are plenty of things you can do to manage it better. Exercise, relaxation techniques like yoga or meditation, and talking to a therapist are all great options for managing stress levels and improving your overall sense of well-being.

  • Medications

    • Certain medications can cause fatigue as a side effect. If you’re taking any prescription drugs, be sure to check the list of possible side effects; fatigue is a common one. If you think your medication might be to blame for your fatigue, talk to your doctor about changing doses or switching to a different drug altogether. Better yet, find out if there is a natural alternative that can replace the medication. In many cases, there are safer, more natural ways to treat health conditions without medication.

Bottom line…fatigue is a common issue that can have many different causes. If you’re feeling tired all the time, look at your lifestyle and see if there are any changes you can make to improve your sleep habits or nutrition. You might also want to talk to your doctor about possible underlying health conditions like anemia or stress that could be contributing to your fatigue levels. By taking some simple steps to improve your overall health and wellbeing, you may just say goodbye to fatigue for good!
