From Tiredness to Persistent Fatigue: Understanding and Managing Energy Levels

Posted by Farzannah Nasser on

Most of us experience tiredness at some point, often after a poor night's sleep or a particularly busy day. This kind of fatigue is usually temporary and can be alleviated with rest, proper nutrition, and hydration. However, persistent fatigue is a more severe and enduring condition that requires a comprehensive approach to identify the root cause and implement effective interventions.

Ordinary Tiredness is often the result of:

  • Lack of Sleep: A single night of insufficient sleep can leave you feeling drained but is usually remedied by a good night's rest.
  • Physical Exertion: Intense physical activity can lead to temporary fatigue, which resolves after adequate rest.
  • Mental Stress: High levels of stress can lead to tiredness, which generally improves with relaxation and stress management techniques.

Persistent Fatigue, on the other hand, is characterised by:

  • Long-Lasting Exhaustion: Fatigue that lasts for more than six months and is not relieved by rest.
  • Whole-System Impact: It affects multiple aspects of life, including physical, mental, and emotional well-being.
  • Underlying Health Issues: Often associated with conditions such as autoimmune diseases, thyroid disorders, or chronic infections, requiring a holistic approach to treatment.

If you experience unexplained fatigue, it is crucial to consult your doctor to investigate potential underlying health issues and receive appropriate treatmen

Potential Nutrient Deficiencies Contributing to Tiredness and Fatigue

Nutrient deficiencies can significantly contribute to feelings of tiredness and fatigue. Ensuring a balanced intake of essential vitamins and minerals is crucial for maintaining energy levels.

Here are some key nutrients to be mindful of:

  • Iron. Essential for producing haemoglobin, a protein in red blood cells that carries oxygen throughout the body. Deficiency Symptoms: Fatigue, weakness, pale skin, and shortness of breath. Dietary Sources: Red meat, poultry, fish, lentils, beans, and fortified cereals.
  • Vitamin B12. Crucial for nerve function, red blood cell production, and DNA synthesis. Deficiency Symptoms: Fatigue, weakness, anaemia, and neurological issues like tingling or numbness in extremities. Dietary Sources: Red meat, dairy products, eggs, and fortified plant-based milks or cereals.
  • Vitamin D. Important for bone health, immune function, and energy production. Deficiency Symptoms: Fatigue, bone pain, muscle weakness, and mood changes. Dietary Sources: Sunlight exposure, fatty fish, fortified dairy products, and supplements.
  • Magnesium. Involved in over 300 biochemical reactions, including energy production, muscle and nerve function, and blood glucose control. Deficiency Symptoms: Fatigue, muscle cramps, mental disorders, and irregular heartbeats. Dietary Sources: Nuts, seeds, whole grains, leafy green vegetables, and legumes.
  • Folate (Vitamin B9). Necessary for DNA synthesis, red blood cell formation, and overall cellular function. Deficiency Symptoms: Fatigue, weakness, irritability, and difficulty concentrating. Dietary Sources: Leafy green vegetables, legumes, nuts, seeds, and fortified grains.

Ensuring a diet rich in these nutrients can help combat tiredness and persistent fatigue. If you suspect you have a deficiency, it's essential to consult with a qualified nutritionist for proper testing and supplementation if needed.

The Role of the Circadian Rhythm

Our bodies follow a natural internal process known as the circadian rhythm, which regulates the sleep-wake cycle and repeats roughly every 24 hours. This rhythm influences various bodily functions, including hormone release, eating habits, digestion, and body temperature. Understanding and optimising your circadian rhythm can significantly impact your energy levels, feelings of tiredness and overall health.

Key Components of the Circadian Rhythm:

  • Suprachiasmatic Nucleus (SCN): Located in the hypothalamus, the SCN is the central pacemaker of the circadian rhythm. It receives information about light exposure from the eyes and adjusts the timing of the sleep-wake cycle accordingly.
  • Melatonin Production: Melatonin, a hormone produced by the pineal gland, plays a crucial role in regulating sleep. Its production increases in the evening as it gets darker, promoting sleep, and decreases in the morning when exposed to light, promoting wakefulness.
  • Cortisol Levels: Cortisol, often referred to as the "stress hormone," follows a circadian pattern with levels peaking in the early morning to help wake you up and gradually declining throughout the day.
  • Body Temperature: Your body temperature fluctuates throughout the day, being higher during the day and lower at night, which helps signal sleep and wakefulness.

Disruptions to the Circadian Rhythm and Their Effects

Several factors can disrupt your circadian rhythm, leading to various health issues, including persistent fatigue.


Common Disruptors:

  • Irregular Sleep Patterns: Inconsistent sleep schedules, such as varying bedtimes and wake times, can confuse your internal clock.
  • Shift Work: Working night shifts or rotating shifts can severely disrupt your circadian rhythm, as it requires being awake and active during times when your body expects to be asleep.
  • Exposure to Artificial Light: Prolonged exposure to artificial light, especially blue light from screens, can inhibit melatonin production, making it harder to fall asleep.
  • Jet Lag: Rapid travel across multiple time zones can cause a mismatch between your internal clock and the external environment, leading to symptoms of jet lag.

Managing and Minimising the Effects of Jet Lag

Jet lag occurs when there is a disruption to the circadian rhythm, typically due to rapid long-distance travel across multiple time zones. Symptoms of jet lag include sleep disturbances, tiredness/daytime fatigue, difficulty concentrating, and digestive issues.

Here are some strategies to manage and minimise the effects of jet lag:


Pre-Travel Preparation

  • Adjust Sleep Schedule: Gradually adjust your sleep schedule several days before travelling to match your destination's time zone. This can help your body begin to acclimate to the new schedule.
  • Light Exposure: Plan light exposure to shift your circadian rhythm. If travelling east, seek morning light exposure. If travelling west, seek evening light exposure.

During Travel

  • Stay Hydrated: Drink plenty of water to stay hydrated, as dehydration can exacerbate jet lag symptoms. Avoid alcohol and caffeine, which can disrupt sleep.
  • Move Around: Periodically get up and move around during the flight to maintain circulation and reduce stiffness.

Post-Arrival Adjustments

  • Spend Time Outdoors: Natural light exposure helps reset your circadian rhythm. Spend time outdoors during daylight hours at your destination.
  • Align with Local Time: Upon arrival, immediately adjust your schedule to the local time. Eat meals and sleep according to the new time zone.

By understanding how energy is produced in the body and the factors that affect this process, you can make informed choices to maintain your energy levels and overall health. Protecting your mitochondria through a balanced diet, regular exercise, stress management, and adequate sleep will ensure your cells continue to produce the energy you need to thrive. Recognising the role of the circadian rhythm and implementing strategies to maintain its natural cycle can further enhance your well-being and prevent persistent fatigue. If you experience unexplained fatigue, it is crucial to consult your doctor to investigate potential underlying health issues and receive appropriate treatment.
