Feeling tired all the time? Fatigue and weakness are common issues that affect many people, even those who eat a balanced diet and get enough rest. If constant tiredness persists despite a healthy lifestyle, it may indicate an underlying health problem. Experts say fatigue can have multiple causes, from nutritional deficiencies to medical conditions. Let’s explore the major reasons behind persistent fatigue and how to manage it effectively.

1. Depression and Stress

Mental health plays a crucial role in physical well-being. According to the American Psychological Association, chronic stress and depression can increase cortisol hormone levels, leading to low energy and constant fatigue. Moreover, stress can disrupt sleep patterns, making it difficult for the body to recover, which in turn worsens tiredness.

2. Nutritional Deficiencies

A lack of essential nutrients can directly impact energy levels. Iron deficiency (anemia), in particular, leads to low hemoglobin levels, reducing the oxygen supply to the body and causing fatigue.

The National Institute of Health (NIH) reports that around 40% of the global population suffers from iron deficiency. Other vital nutrients like Vitamin B12 and Magnesium also play an essential role in maintaining energy levels, and their deficiency can contribute to fatigue.

3. Anemia (Low Red Blood Cell Count)

Anemia occurs when the body doesn’t produce enough red blood cells (RBCs). These cells transport oxygen to the organs, and their deficiency can lead to constant tiredness and weakness. Common causes of anemia include a lack of iron, folic acid, or Vitamin B12.

4. Sleep Apnea

Sleep apnea is a sleep disorder in which breathing repeatedly stops and starts during sleep. This disrupts deep sleep, preventing the body from getting adequate rest. As a result, people with sleep apnea often feel exhausted throughout the day, regardless of how long they sleep. If you frequently feel sleepy during the day, sleep apnea might be the cause.

5. Diabetes

People with diabetes often experience constant fatigue and weakness. When blood sugar levels are not well-regulated, the body struggles to convert glucose into energy. This leads to low energy levels, sluggishness, and tiredness.

6. Dehydration

Water is essential for maintaining energy and overall body function. When the body lacks enough water, blood circulation slows down, and muscles feel weak, leading to fatigue. To prevent dehydration, drink at least 8-10 glasses of water daily.
