Feeling lifeless when you wake up in the morning, feeling extremely tired even after doing small tasks, and always wanting to lie down—this is a major problem that bothers most people today. Fatigue caused by mere physical exertion will go away with rest. But chronic fatigue that doesn’t go away no matter how much rest you get may be due to a lack of some important nutrients in the body or other diseases. Here are the 5 main scientific reasons behind this:
Anemia: The most important scientific reason behind chronic fatigue is anemia. The oxygen we breathe is carried to the cells and organs of the body by hemoglobin in the red blood cells. When there is a deficiency of iron in the body, the production of hemoglobin decreases. As a result, the cells do not get enough oxygen and the body always shows extreme fatigue and shortness of breath.
Vitamin D3 and Vitamin B12 Deficiency (Nutritional Deficiencies): Vitamin B12 and vitamin D3 are essential for the energy production process in our body. B12 is required for the health of the nervous system (when it is low, there will be numbness and fatigue in the limbs). Vitamin D3 maintains the rhythm of bones, immunity and hormones. Deficiency of these two vitamins can cause chronic severe fatigue and muscle pain.
Hypothyroidism: The hormones released by the thyroid gland in the front of our neck control the body’s metabolism (the process of converting food into energy). The condition of decreased production of thyroid hormone is scientifically called hypothyroidism. As the body’s energy production slows down, people with this disease experience extreme fatigue, obesity, depression, hair loss and always feeling cold.
Diabetes and Insulin Resistance: The main symptom of diabetes is feeling extremely tired despite having high levels of glucose (sugar) in the blood. This condition occurs when the hormone insulin is unable to transport the glucose from the food you eat into the cells and convert it into energy (Insulin Resistance). Just as a car does not run even though it has fuel, the body is always tired if the cells do not get energy even though there is sugar in the blood.
Chronic Stress & Insomnia: In people with chronic severe mental stress, the body always produces stress hormones like cortisol. This always makes the brain and muscles work excessively (Burnout). Along with this, not getting exactly 7-8 hours of deep sleep at night can also cause extreme fatigue and lack of attention during the day.
