SCIENCE, SOFTLY EXPLAINED

When fatigue becomes your normal

By Dr Haïfa Machat · Published

Persistent fatigue deserves curiosity, not an automatic diagnosis of stress. A pharmacist's perspective on possible causes, useful observations and the limited role of rituals.

Key takeaways

  • Persistent fatigue is a symptom to investigate, not a diagnosis of stress or a 'dysregulated nervous system'.
  • Noting its duration, patterns and associated symptoms can help a healthcare professional assess it.
  • A mindful pause may support your day; it does not replace medical evaluation.

Fatigue is a symptom, not a diagnosis.

We can grow used to almost anything, including waking without energy. What begins as a demanding week can become the background of everyday life: concentration fades and activities we enjoy take more effort. This experience deserves attention without panic and without being dismissed.

Possible causes include insufficient or disturbed sleep, stress, medication effects, anaemia, thyroid conditions, sleep apnoea, infections and other situations. A systematic review in primary care illustrates how varied the diagnoses associated with tiredness can be. It would be reductive to call every persistent fatigue a 'dysregulated nervous system'. Equally, not seeing an obvious cause does not mean there is nothing to examine. [1][4]

Observe before you conclude.

When did the fatigue begin? Does rest change it? How are you sleeping? Does your energy fluctuate during the day? Have your medication, routine or activity changed? A short diary can help you describe patterns at a consultation. This is observation, not self-diagnosis or an invitation to watch every sensation with fear. [4]

A ritual is not a treatment.

A minute of attentive breathing, a screen-free pause or gentle movement can make room to notice how we feel. Research into mindfulness programmes suggests possible benefits for some psychological symptoms. In one meta-analysis, evidence for stress or distress was more limited than for anxiety. A separate review found effects on sleep quality against some control groups, but not against specific sleep treatments. These studies investigated programmes over weeks; they do not show that a minute of breathing treats fatigue. [2][3]

Science and sensitivity can meet here: take evidence seriously while making room for lived experience. Gentleness should help us listen more accurately, not look away from a symptom.

When should you seek help?

If fatigue lasts for several weeks, does not improve, interferes with daily life or comes with other symptoms, arrange a medical appointment. A professional can explore causes that matter in your situation. Write down what you notice and bring those observations with you. [4][5]
