Introduction to Fatigue

Fatigue is the sensation of tiredness, weakness and lack of energy. It is different from drowsiness. Drowsiness is feeling of wanting to sleep, while fatigue is a lack of energy and motivation to do daily tasks. It can occur due to various factors such as any underlying health condition, poor sleep patterns, poor diet and lack of physical activities. 

Lack of sleep may be the major cause. However, it is not necessary that fewer sleeping hours are the only cause of fatigue. Furthermore, it has been observed that men and women differ in the way they describe fatigue. Men typically say they feel tired, whereas women say they feel depressed or anxious.

If you are taking proper nutrition, supplements, and sleep and are physically active but still experiencing fatigue, consult your doctor for the diagnosis. They can figure out the cause of fatigue and help you deal with it.
