Short answer: Constant tiredness usually traces to poor sleep quality, chronic stress, blood-sugar swings, or low iron/thyroid function. Fixing sleep and blood sugar, managing stress, and supporting energy with adaptogens addresses the most common causes. But persistent fatigue deserves a check-up.
The usual suspects
- Sleep quality: hours in bed aren't the same as restorative sleep.
- Chronic stress: a flattened cortisol curve leaves you drained.
- Blood sugar: spikes and crashes feel like fatigue.
- Iron, B12, thyroid: common, checkable medical causes.

When to see a doctor
If fatigue is sudden, severe, or comes with other symptoms, ask for bloods (iron, thyroid, B12).
