Explanation
A person can feel tired (also known as fatigue) for various reasons. For example, fatigue can be a symptom of anemia, depression, a thyroid problem, or a sleep disorder, among other possible causes.
Anemia is when the number of red blood cells in the body is lower than normal; there are multiple reasons why someone may have anemia and a healthcare provider can investigate what may be causing anemia (and/or fatigue). When someone is experiencing depression, they can have symptoms including mood changes as well as feeling sleepy and/or lacking energy. When the thyroid does not make enough thryoid hormone, a person can feel tired all the time. Sleep disorders include sleep apnea, restless leg syndrome, and other conditions.
If you are wondering why you often feel tired, you should contact a healthcare provider to receive a personalized medical evaluation and advice.
