Extreme fatigue that does not go away no matter how many hours you sleep at night, excessive lethargy during the day, and inability to concentrate on work—this is a major health problem faced by most people today. Although many people dismiss it as just laziness, it is actually due to some hormonal changes and nutritional deficiencies in the body. Here are the 5 main scientific reasons behind the disruption of the body’s energy levels:
Anemia & Iron Deficiency: The most important scientific reason for fatigue is anemia. Hemoglobin in the blood carries oxygen to billions of cells in the body. When hemoglobin decreases due to iron deficiency, not enough oxygen reaches the cells. With this, the body’s energy production (Mitochondrial energy) slows down and severe fatigue and lethargy are felt.
Vitamin D3 and B12 Nutritional Deficiencies: Vitamin B12 is essential for the smooth functioning of our nervous system and brain. Its deficiency can cause severe muscle pain and fatigue. Along with this, when Vitamin D3, which plays an important role in regulating the body’s metabolism and boosting immunity, decreases, the body always becomes sleepy.
Hypothyroidism: The hormones released by the thyroid gland in the front of the neck control the body’s metabolism and energy. The condition of decreased thyroid hormone production is called hypothyroidism. This slows down all the body’s functions, resulting in unexplained weight gain, extreme lethargy, and inability to tolerate cold.
Poor Sleep Quality and Sleep Apnea: Even after sleeping for 7 to 8 hours, many people do not get deep REM sleep. People with Sleep Apnea, which causes breathing problems and reduced oxygen during sleep, wake up many times at night without realizing it. This causes extreme fatigue during the day and a tendency to always feel sleepy. Using a mobile phone before going to bed can also destroy the sleep hormone melatonin and cause fatigue.
Dehydration and poor diet: When there is not enough water in the body (Dehydration), blood flow slows down and the heart has to work harder. This can quickly cause fatigue. Also, when you eat too much water, flour, and sweets, blood sugar rises quickly and then drops quickly due to the flow of insulin (Sugar Crash). This is also a factor that causes severe lethargy.
