Common Causes of Fatigue and How to Fix Them

Fatigue is a common complaint that can stem from various underlying causes. Feeling constantly tired or exhausted can greatly impact our quality of life and ability to function optimally. Identifying and addressing the root causes of fatigue is key to regaining energy and vitality. Here are some of the most common causes of fatigue and tips on how to overcome them.

Lack of Quality Sleep

Not getting enough high-quality sleep is one of the most common reasons people feel fatigued. Adults need 7-9 hours of sleep per night, yet many regularly get less due to busy schedules, insomnia, or other sleep disorders. To improve sleep:

  • Maintain a regular sleep-wake cycle by going to bed and waking up at the same times daily. 
  • Limit screen time and stimulants like caffeine before bedtime.
  • Create an optimal sleep environment that is cool, dark, and quiet.
  • Reduce stress through relaxing activities like reading, meditating, or taking a bath before bed.
  • See a doctor if insomnia or other disorders are interfering with sleep.

Poor Diet and Nutrition 

Your diet directly impacts your energy levels. Not eating enough healthy foods or nutrients can lead to fatigue. Tips for improving diet:

  • Eat plenty of fruits, vegetables, and whole grains which provide vitamins, minerals, and fibre.
  • Include lean protein sources like fish, beans, eggs, or chicken.
  • Stay hydrated by drinking enough water throughout the day.
  • Take a multivitamin to fill any nutritional gaps.

If you suffer from periodic energy lulls, try taking a glucose chew to reduce tiredness.

Excess Stress

Chronic stress takes a toll both mentally and physically, often manifesting as constant tiredness. To manage stress:

  • Identify your stress triggers and find ways to mitigate them. 
  • Make time for relaxing activities like yoga, deep breathing, massage, or meditation.
  • Set boundaries and don’t take on too many responsibilities.
  • Focus on things within your control and let go of what you cannot change.
  • Get support from loved ones or see a therapist if stress is overwhelming.

Sedentary Lifestyle

Lack of physical activity can worsen fatigue. Exercise helps increase energy, reduce stress, and lead to better sleep. Try to:

  • Aim for 150 minutes of moderate activity like brisk walking per week.
  • Incorporate strength training 2-3 times a week to build muscle.
  • Take movement breaks throughout your workday.
  • Find an exercise you enjoy like cycling, swimming, or dancing. 
  • Start slow if you are very inactive and increase duration and intensity gradually.

Underlying Health Conditions

Sometimes fatigue results from an underlying medical issue that needs treatment, like anaemia, thyroid disorders, depression, chronic fatigue syndrome, or sleep apnoea. See your doctor if fatigue persists for:

  • Over a month
  • Occurs suddenly or severely
  • Is accompanied by other unexplained symptoms

Get checked for any condition that may be causing your fatigue. Make sure to report all your symptoms and follow treatment plans.

The path to overcoming fatigue starts with identifying and addressing the root causes. Pay attention to your sleep habits, nutrition, activity levels, and health. Making positive lifestyle changes and getting any necessary medical care can help you finally reclaim your energy.
