Fatigue and low energy

Q: What is fatigue and low energy?

## Understanding Fatigue and Low Energy Fatigue is more than just feeling tired after a busy day. It's a persistent sense of exhaustion, weakness, or lack of energy that doesn't improve significantly with rest or sleep. Unlike normal tiredness, fatigue can make even simple tasks feel overwhelming and may persist for weeks or months.

A persistent sense of physical and mental depletion characterised by low energy, reduced motivation, and difficulty sustaining daily activity. Often overlaps with fatigue but emphasises a subjective sense of depleted vitality.
