Why You Might Still Feel Tired Even After Sleeping

Why You Might Still Feel Tired Even After Sleeping | Dr. Ali Ghahary

While sleep requirements can vary slightly from person to person, it’s typically recommended that we get at least 8 hours of sleep each night. Getting an adequate amount of sleep allows us to be able to function at our best (for example, by improving our concentration and productivity), can decrease the risk of developing heart disease and diabetes, improve immune function, and more. However, even with 8 hours of sleep, some individuals say they still feel tired after getting a good night’s rest – and there may be some underlying contributors as to why that’s the case.


One of the most common reasons why someone might still feel tired even after sleeping, or have lingering fatigue throughout the day, is due to being anemic. Anemia is a condition that occurs when you don’t have enough red blood cells. As for what causes this condition, there are a humber of contributing factors, such as taking non-steroidal anti-inflammatory drugs (which can lead to GI problems and stomach bleeds), women who suffer from heavy menstrual periods, hemorrhoids, as well as having chronic diseases such as diabetes or kidney disease.

Even more commonly, anemia is also caused by being deficient in iron, folic acid, or vitamin B12. If you are deficient in any of these things, such as iron, then you should consider increasing your intake of iron-rich foods. In some cases, you may also need to take an iron supplement or get vitamin B12 injections, which can help improve your energy levels and leave you feeling less fatigued.

Mental Health

Mental health conditions, such as depression and anxiety, are two of the most common culprits of chronic fatigue. If you suffer from depression or anxiety, you might find that you’re either not getting enough sleep, having trouble falling or staying asleep, or, in some cases, even sleeping too much. It’s also possible to mistake feelings of depression for fatigue. Along with feeling tired, there are other physical symptoms that can occur with depression, including headaches, upset stomach, cramps, and other general body aches and pains; while other signs of depression aside from fatigue can include feelings of sadness, hopelessness or helplessness, lack of interest in hobbies once enjoyed, poor concentration and difficulty making decisions, as well as changing in eating habits.

It’s just as important to take care of your health exactly as you would every other aspect of your health. For example, if you had a wound, you would get it checked out and treated. Therefore, if you’re feeling depressed or anxious, it’s always important to reach out for help, such as speaking to your physician, to let them know how you’re feeling.


While allergy season is typically at its peak during the spring, one can suffer from allergies year-round. What you might not know is that fatigue can also be a symptom of allergies, along with other symptoms such as sneezing, runny nose, nasal congestion, and red and irritated eyes. When you suffer an allergic reaction, chemicals get released that will help you fight said allergies but may also cause you to feel tired. Sometimes, allergies can be so severe that the symptoms themselves will make it difficult for one to get a good night’s rest which will also lead to fatigue. That lack of sleep combined with symptoms of allergies, can give you a tired, brain fog-like feeling.

To reduce allergy symptoms, your physician may prescribe oral or nasal antihistamines. However, one of the common side effects of some of these medications is also fatigue, so you may want to ask your doctor if there are any non-drowsy alternatives. If you’re still experiencing allergies after trying medications, you may need to be referred to an allergist for further testing.

Chronic Pain

One of the most common chronic pain conditions, known as fibromyalgia, can be another cause of fatigue. While fibromyalgia and chronic fatigue are considered separate conditions, they can often go hand in hand as they each share that feeling of tiredness. With fibromyalgia, it’s not uncommon to feel like you’re always tired and never get a good night’s rest. You may also find that, due to your pain, your sleep is always interrupted.

One of the best ways to reduce the effects of fatigue associated with fibromyalgia is with exercise, although it should be low impact so that you do not add to your fatigue. As your body becomes better adjusted to physical activity, you can slowly increase how much you do.
