We lead hectic lives wherein feeling washed out is perfectly normal. But if this tiredness becomes overwhelming and is not being relieved by sleep, then it can be a sign of an underlying health condition. Here are the top 5 reasons why you have fatigue despite getting proper rest.


Fatigue can be caused due to iron deficiency or anemia. Lack of iron in the body means that your body it’s not getting the oxygen it needs for energy. Women having heavy menstrual bleeding or are pregnant have a higher risk of anemia.

Iron-rich foods

  • Green veggies
  • Lentils
  • Beans
  • Nuts and seeds

Go for the Complete Blood Count (CBC)

CBC is one of the first tests done to check the possibility of anemia. It measures all the components of blood including red blood cells (RBCs), white blood cells (WBCs), and platelets. Low RBC count indicates your anemic.

Vitamin B12 deficiency

Vitamin B12 is an essential nutrient that plays an important role in maintaining your overall health. Lack of this nutrient can lead to its deficiency with symptoms of fatigue, appetite loss and tingling sensation in hands and feet. Therefore, this deficiency is quite common in vegetarians and vegans.

Vitamin B-12 sources

Underactive thyroid

The thyroid gland makes hormones that are responsible for maintaining some major functions in the body. To function properly, it needs a good supply of iron which comes from your diet. This gland becomes underactive when it produces too little thyroid hormone in your body which in turn can make you feel tired.

Iodine-rich foods

  • Spinach, broccoli
  • Red meat
  • Legumes
  • Quinoa

Go for the thyroid test

Not just fatigue, an underactive thyroid gland can also lead to hair fall, weight gain, aching muscles and even depression. A thyroid test measures the level of your thyroid hormones. Low levels of the hormones indicate hypothyroidism and high levels indicate hyperthyroidism. Both of them are serious health conditions wherein medical intervention is a must.

Vitamin D deficiency has become quite common in people living in urban areas. Low levels of this nutrient can lead to fatigue, bone and muscle pain. Vitamin D is important for the body since it is needed to keep our teeth, bones and muscles healthy. 

Vitamin D sources

  • Sunlight-the best source
  • Milk
  • Cheese
  • Fatty fish
  • Egg yolk

Go for the vitamin D test

A vitamin D test checks the level of vitamin D in the body. If the deficiency is ignored for a long time, it can lead to rickets in children and osteomalacia in adults. Sometimes, people may have vitamin D deficiency but will not know since they do not exhibit any symptoms. So, if you are a working professional, it is recommended that you take the test at least once a year.
