Why Am I Feeling More than Tired?

Fatigue is more than just feeling sleepy — it’s a constant state of tiredness that can be physical, mental, or both. Normal tiredness usually improves with rest or sleep. Ongoing persistent fatigue doesn’t always resolve after a good night’s sleep and may affect motivation, concentration, and daily functioning.

Acute fatigue is short-term and often linked to temporary stress, illness, or lack of sleep. Chronic fatigue lasts for several weeks or longer and may signal an underlying medical or psychological condition.

Common Causes of Fatigue

There are many potential causes of fatigue, ranging from lifestyle factors to medical conditions. They can include:

Lifestyle Factors (Sleep, Diet, Stress)

Poor sleep hygiene, shift work, and high stress levels can contribute to ongoing tiredness. Inadequate nutrition, dehydration, and excessive caffeine or alcohol intake may also affect energy levels. In our busy lives, workplace stress and long hours is another common factor when it comes to physical and mental fatigue.

Medical Conditions

Health conditions such as iron deficiency, thyroid disorders, diabetes, sleep apnoea and infections can cause unexplained fatigue. Anxiety, depression and prolonged stress are also common contributors to ongoing fatigue. A thorough medical review is important to rule out underlying illness.

Medications

Some prescription and over-the-counter medicines can list tiredness as a side effect. Your GP can review your medications if fatigue develops after starting a new treatment.

Signs and Symptoms of Fatigue

Fatigue presents in different ways from person to person, but common symptoms are:

Physical Symptoms

• Constant tiredness
• Muscle weakness
• Headaches
• Reduced stamina

Cognitive Symptoms (Poor Concentration, Brain Fog)

• Difficulty focusing
• Memory lapses
• Slower thinking or brain fog

Emotional Symptoms

• Irritability
• Low motivation
• Feeling overwhelmed

Practical Tips for Managing Fatigue

While medical input may be necessary, simple changes can help you manage fatigue. Try:

• Maintaining a consistent sleep schedule and limiting screen time before bed.
• Eating balanced meals rich in whole foods and staying hydrated to support steady energy levels.
• Engaging in regular light exercise and relaxation techniques helps improve mood and stamina over time.

It’s important to seek medical advice if your symptoms persist or if you experience chest pain, shortness of breath, unexplained weight loss, or severe or sudden fatigue. If your fatigue symptoms last more than a few weeks, are getting worse, or are affecting your work, study, sleep, or relationships, it’s time to book a GP appointment.
