An occasional sleepless night might leave you tired and unpleasant to be around, but repeated sleeplessness and chronic exhaustion can have serious effects on your long-term health and state of mind. If you are frequently overly tired, your ability to function and interact will be affected in many ways.
Exhaustion, due either to extreme physical exertion or extended sleeplessness, affects your ability to communicate and interact with others. You may experience irritability, memory loss, difficulty speaking and depression. Depression can also be a cause of insomnia, which leads to further exhaustion and exhaustion-related problems.
Deprived of adequate rest, your mind has difficulty functioning normally. You may also experience dizziness, blurred vision or mild hallucinations. These problems can affect your spacial perceptions and prevent you from executing tasks that require even nominal levels of dexterity or eye-hand coordination.
Observable Physical Effects
When you are overly tired, your body's systems begin to act in unusual ways. This can lead to nausea or tremors, which further complicate the difficulties presented by the cognitive effects of exhaustion. If you experience long-term exhaustion, dramatic weight loss or weight gain can occur.
The Unseen Effects of Being Overly Tired
Two common health conditions related to chronic fatigue are hypertension and heart disease. Because of the seriousness of these conditions, you should seek the advice of a medical professional if you are affected by fatigue, exhaustion or sleeplessness in other observable ways.
In many cases, sleeplessness or fatigue are due to depression, lack of physical activity, an unbalanced diet or the over-use of stimulants such as caffeine and nicotine. When these causes have been eliminated and your exhaustion persists, you may have a more serious concern. Many other factors, including brain tumors, can cause you to be overly tired. Because your exhaustion can be a symptom of something much more serious, it is important to work with your physician to determine the exact cause.
