Causes of Fatigue
Not Enough Sleep
It may seem obvious but you could be getting too little sleep. That can negatively affect your concentration and health. Adults should get seven to eight hours every night.
Not Enough Fuel
Eating too little causes fatigue, but eating the wrong foods can also be a problem.
Depression
You may think of depression as an emotional disorder, but it contributes to many physical symptoms, as well. Fatigue, headaches, and loss of appetite are among the most common symptoms. If you feel tired and “down” for more than a few weeks, see your doctor.
Hypothyroidism
When the thyroid gland is underactive and the metabolism functions too slowly, you may feel sluggish and put on weight.
Caffeine Overload
Caffeine can improve alertness and concentration in moderate doses. But too much can increase heart rate, blood pressure, and jitteriness.
Sleep Apnea
Some people think they’re sleeping enough, but sleep apnea gets in the way. It briefly stops your breathing throughout the night.
Diabetes
If you have persistent, unexplained fatigue, ask your doctor about being tested for diabetes.
Dehydration
Whether you’re working out or working a desk job, your body needs water to work well and keep cool. If you’re thirsty, you’re already dehydrated.
Fibromyalgia
If your fatigue lasts more than six months and is so severe that you can’t manage your daily activities, chronic fatigue syndrome or fibromyalgia are a possibility.
