What causes fatigue?

Before you can begin to overcome your fatigue, you need first to understand what fatigue is all about. Fatigue is often referred to as lethargy or exhaustion and is that feeling of tiredness and weakness, both physically and mentally.
You can experience temporary fatigue, which is a result of too much work or not getting enough rest. This kind of fatigue can be easily overcome. There is also chronic or medical fatigue, which is more long-term and requires more serious treatment to overcome.
According to research, 10 percent of the world population suffers from fatigue at any given time, with females being affected by
fatigue more than males. Most cases of fatigue have underlying mental causes rather than physical causes and one out of five people who suffer fatigue in the United States, states that it affects their normal function and daily lives.
Two Types of Fatigue
There are two kinds of fatigue that you can suffer from, physical fatigue and mental fatigue. Physical fatigue is when you have a hard time doing the things that you usually do, like carrying grocery bags or climbing stairs.

Physical exhaustion is just not having enough physical strength to complete daily tasks.
Mental, or psychological fatigue, on the other hand, is when you find it difficult to concentrate on things. In severe cases, you may find even the prospect of getting out of bed to be too much work.
You may feel tired all the time and may also suffer from a lower level of consciousness, which can be extremely dangerous, especially when driving or operating heavy machinery. If you suffer from mental fatigue, you may be mistaken for being drunk or intoxicated.
Weakness Often times, when referring to fatigue, the words sleepiness and weakness are used to describe the condition. When the phrase
weakness is used, it refers to a situation where your muscles just don't have enough strength to complete even the simplest of physical tasks.
When you experience weakness as a symptom of fatigue, you often need to apply extra effort just to move your arms, legs, and other body parts. This is usually a result of overexerting yourself at some point, like when running a marathon or spending the entire day hiking.
Your body will feel tired and weak, and you’ll experience some aches and pains. Fortunately, with enough rest,

these symptoms will disappear after a couple of days.
Sleepiness
Sleepiness, also called somnolence, is when you feel sleepy even when you are in the middle of an activity. This can be as a result of not getting enough sleep, which is necessary for you to feel rejuvenated and make you feel more relaxed.
Causes of Fatigue
To overcome fatigue, you must understand the root causes behind it. If you can eliminate the root causes from your life, you can permanently get rid of fatigue from your life. The origins of
fatigue can be divided into three main groups; lifestyle, psychological, and medical.
