We all feel tired at some time during the day. Then at night, you go to sleep, then arise after a good night’s sleep.
But some feel tired for weeks. If that’s the case, mental fatigue—or a lack of energy and motivation—may be the culprit. Mental fatigue can also cause temporary lapse in cognitive performance.
Mental fatigue is not drowsiness, weakness, and apathy. Neither is it physical fatigue, which you normally experience after physical exertion.
It can also be recognized as:
- Somnolence: When you have a strong desire to sleep, or sleep for really long periods.
- Lethargy: Extreme fatigue or drowsiness.
- Directed Attention Fatigue: When the concentration centres of the brain become fatigued.
What causes mental fatigue?
Mental fatigue can arise from various factors, including:
- Infection.
- Medications (like antidepressants, antihistamines, and nausea/pain medicines)
- Medical treatments (like chemotherapy and radiation)
- Major surgery
- Psychological disorders (like anxiety, depression, grief, and stress)
- Personal habits (like staying up too late, eating too much, drinking too much caffeine or alcohol)
How do I manage mental fatigue?
Those with mental fatigue are mainly tired for several weeks without any relief. Your healthcare provider can help diagnose this condition, often by asking questions about sleep patterns, daily activities, appetite, and exercise. You may also receive a physical exam, blood tests, or a sleep study.
Treatment regimens are based on your health history and test results. Lifestyle changes may also be recommended, including:
- Taking short naps instead of long ones
- Moderate exercise, including breathing exercises (like tai chi or yoga)
- A fatigue diary
- A well-balanced diet
- Stopping smoking
