Fatigue is something every human being has experienced at some point in his or her lives. It is a problem to get out of bed and even when you do, it feels like you could die of exhaustion if you do not have a nap in the afternoon. And the more you sleep, the more tired you feel. However fatigue can be cured, but it is important to distinguish when it is a one - off and a result of changes in the lifestyle and when it is a medical problem.

Sometimes stress can be the cause of fatigue, if you are rushed on your feet and under constant stress it means even when you slow down you cannot relax. Eventually lack of relaxation will wear you down.

Lack of sleep is another common cause, be it that you go to sleep late, wake up earlier in the morning or you are unable to get decent, uninterrupted sleep. It can all lead to lower energy levels and drowsiness. Lack of proper nutrition as well as dehydration can lead to fatigue as your body will be lacking fluids and the essential nutrients it needs to function at its optimum.

Excluding physical activity out of your daily routine may also lead to fatigue. You are tired so you do not feel like exercising, but even when you do you get tired more easily. Benefits of mild to moderate workout 5 days a week are plenty, better mood, higher energy levels and less stress. However make sure not to exercise too close to bedtime. If you are on some types of medication it can also lead to fatigue problems. Antihistamine and beta-blockers make you drowsy, while some painkillers that contain caffeine may keep you up at night.

All of these factors are lifestyle changes and if addressed accordingly fatigue should be gone over a short period of time. However even if you do make the changes in your lifestyle and get plenty of rest, but are still suffering from fatigue you might have to consult a doctor to find the medical cause. Fatigue might be a symptom of some of the following medical conditions anemia (lack of iron in the blood), restless leg syndrome (main characteristic is that the legs can not stand still, resulting in restless sleep), diabetes, cancer, sleep apnea or thyroid problems.

Fatigue in general is a sign that certain changes have to be made in your lifestyle so pinpoint the case and make the necessary changes. However if fatigue persists consult a doctor.
