Fatigue is a common symptom that can have many causes. It is a feeling of tiredness, exhaustion, weariness, or lack of energy. Nearly everyone experiences fatigue at some point.
There are two main types of fatigue: physical fatigue and mental fatigue. Physical fatigue occurs after extended periods of physical activity, such as exercise or hard labor. The muscles feel weak and tired. Mental fatigue, on the other hand, is more linked to brain function and occurs after long periods of cognitive activity that drain mental resources, like studying, thinking critically, or completing complex tasks. Mental fatigue can make it hard to concentrate, solve problems, or be productive.
Some common causes of fatigue include:
- Lack of sleep - Not getting enough quality sleep can lead to next-day fatigue. Adults need 7-9 hours per night.
- Poor diet - Eating too much unhealthy food or not enough nutrients can cause fatigue. Make sure your diet includes plenty of protein, fruits, vegetables, and whole grains. Stay hydrated as well.
- Stress - Ongoing stress and anxiety tires out the body and mind. Try relaxation techniques like yoga, meditation, or deep breathing. Talk to a counselor if needed.
- Depression - The feelings of sadness, hopelessness, and lack of motivation in depression can manifest as fatigue. See a doctor if fatigue persists.
- Medications - Some prescription drugs can cause fatigue as a side effect. Check with your pharmacist.
- Underlying health issues - Various medical conditions like anemia, diabetes, thyroid issues, heart disease, cancer, and autoimmune disorders can lead to fatigue. See your doctor.
- Lack of physical activity - Inactivity causes loss of strength and endurance. Doing regular exercise helps fight fatigue.
There are ways to manage fatigue:
- Get enough sleep and improve sleep habits. Keep a consistent bedtime. Limit blue light exposure at night. Make sure your bedroom is dark, cool, and quiet.
- Eat a balanced, nutritious diet and stay hydrated. Limit caffeine, sugars, and processed foods. Take vitamins if deficient.
- Reduce stress through relaxation techniques, sufficient rest, and fun activities. Try not to overschedule yourself. Ask for help when needed.
- Treat any underlying medical or mental health issues. See your doctor for a checkup.
- Exercise regularly to build strength and stamina. Start slow if very fatigued. Even light activity helps.
- Listen to your body and rest when needed. Take breaks between demanding tasks. Don't push yourself to exhaustion.
- Limit alcohol, which can worsen fatigue. Avoid sedatives and sleeping pills long-term.
If fatigue persists, be sure to see a doctor to identify any underlying causes. Blood tests can check for anemia, thyroid issues, vitamin deficiencies, and more. Your doctor may refer you to a sleep specialist if you have signs of a sleep disorder contributing to fatigue.
