Fatigue is defined as an overwhelming sense of tiredness, lack of energy, and feeling of exhaustion. It can have physical or mental causes. We all experience fatigue at some point from things like lack of sleep, overexertion, stress, or even boredom.
What causes physical fatigue?
Physical fatigue often comes from:
- Hard physical work or exercise
- Lack of sleep or poor sleep quality
- Dehydration or poor nutrition
- Illnesses like anemia, cancer, heart disease, etc.
- Medications, supplements, or other drugs
- Pregnancy
Your muscles use up energy stores. Lactic acid builds up. Your body then forces you slow down so your muscles recover. That feeling is physical fatigue.
What about mental fatigue?
Mental fatigue happens when your brain gets overworked. Causes include:
- Stress from work, family, health issues, etc.
- Information overload
- Lots of mental tasks without breaks
- Poor sleep
- Depression or anxiety
Mental fatigue differs from physical fatigue. But they often go together. A tired body leads to a tired mind and vice versa.
How can you manage fatigue?
Too much fatigue takes a toll on your health and happiness. Try these tips:
- Get enough sleep
- Exercise in moderation
- Eat nutritious foods and stay hydrated
- Take breaks from demanding tasks
- Set priorities and avoid overscheduling
- Reduce stress through relaxation techniques
See your doctor if fatigue lasts weeks. They can check for underlying issues. Treating things like sleep apnea, anemia, or depression may improve your energy.
In summary, fatigue is the body and brain signaling its needs. Listen to these signals. Make rest and self-care a priority in order to have the energy you desire.
